Dave, I just had a conversation this morning with my local garage about aftermarket suspension and the guy summed it up nicely " Some people buy aftermarket dampers and then spend all their time trying to get it set up as though they had Bilsteins" Not a dig at you

After going trying

Gaz Nickles
Gaz Gold Pros
Gaz Monos

All were terrible.

I think the Nitrins are the business , I run them soft for the road and a TVR specialist thought they were Bilsteins.
They are useable in any setting not like GAZ.
biggrin there we go
I'm listening to ray von and I'm listening to Ben Lang, but mostly I'm listening to the things I've discovered myself over the last few days. What I've not been listening to over the last two days is all the banging, crashing and rattles my Chimaera suspension has been making for the last few years.

All this came out of an happy accident really, I only fitted the Bilsteins while the GGPs were being rebuilt so I could move the car about, and I only drove it for a bit of fun to see how dreadful the ride and handling was in this state.

It's genuinely come as a massive surprise to me but I now have to accept what I'm looking for from the ride and handing of my Chimaera may be yellow and have a Bilstein sticker on it scratchchin

A custom Tuscan S sprung & valved set of Bilsteins bespoke built for 'Ol Gasbag's' special requirements, with the addition of the proper modern type road focussed drop links we've been discussing here may well deliver the perfect noise free compliant ride with tight handling I've been dreaming of all along.

It's a funny old world chaps rolleyes

We're all in the shed trying to find them old rusting Bilstein's.

I don't know if it's just me but I go from thinking my adjustables are terrible to thinking there not bad at all, is it a mood thing.

Maybe your Gaz were so shot anything would feel better

As this is so fundamental to the enjoyment of the car will you just have another drive before swapping to the Gaz again Dave, just to be sure your happy with the Bilstein's and then try the Gaz.

It's just some days I think mine are good then other days not so, your pleasant surprise today might not feel quite so tomorrow kind of thing!

That's a very good point. Only really applies if Dave was ever totally happy with the way the car handled with his Gaz shocks on, but I know what you mean.

I definitely agree with this Alun, the first 50 miles or so on the GGPs never bothered me but they would either go off after that or I would progressively get more and more tiered with the ride. Saying that they're fine on the motorway, actually I had no issues with them at all when covering big miles on smooth roads its just I don't spend my entire time on the motorway. As soon as I turn off the motorway especially onto a 'B' road the ride becomes poor.


ClassiChimi said:

Absolutely Alun, my rear GGPs were indeed totally shot but my above observations and experiences come right from the day I fitted the brand new set. For the first six months the front end had an annoying habit of nodding, this calmed down as the springs settled but they were never what I'd call a comfortable damper offering a compliant ride on 'B' roads or poor surfaces.

Absolutely I will Alun, I'm going to Kop Hill this Sunday with the boys which will give the Billies another good workout, following this there'll be a lot of swapping back and forth of the different brands of coil overs over the next month or so including trialling ARB connected & disconnected to explore every single permeation. Last Sunday I took the car out with the old Billies back on and no anti roll bar simply to see what happened, I only did about 10 gentle miles so it didn't really tell me anything. I then did 100 miles yesterday but only because my wife had accidentally gone to work with my Toyota keys, if she hadn't taken those keys I would have taken the company car instead and never would have found out just how compliant my old billies really are. I actually ended up with so much confidence in the way the car rode & handled I started having some back road fun in a way that would have had the car banging and crashing about on the GGPs... even when they were brand new.


ClassiChimi said:

Again I tend to agree, our moods change and the way we drive will change with our mood. The other thing that changes is the type of roads we're driving on that day, a lot of motorway work when I'm feeling chilled out and the GGPs are just fine, but if I'm in the mood for some back road scratching those GGPs can be way too harsh.

No surprise really when you look at how the GGP solid spacer rose joint rigidly connects them to the TVR chassis....



Compare this with the big rubber bush you get on the Bilsteins.



Damper sophistication aside my experience with drop links is a solid rose joint can never offer the comfort/compliance of a vibration and shock isolating rubber bush. If the Billies also offer better damping as I suspect they do, their rubber bushed connection with the chassis combined with some modern road type drop links should deliver three clear ride quality improvements over the GGPs & Leven rose jointed drop links I've been running for the last few years.

Rose joints really have no place on a road car, great for race car but my Chimaera is not a race car, I don't even do track days with it so why I chose to rose joint everything is beyond me?

I now need to put the type of suspension on my TVR that actually suits what I want from my car, rather than trying to turn it into a race car only to discover track focussed suspension will never give me the nice compliant on road ride quality I seek.

Bilsteins were only on early cars - TVR switched to HBE in 1995 and back to Bilstein in 2004/5, well after the end of the Chimaera production run. So people who say 'their Bilsteins were awful' might well have run on HBE bicycle pumps that were fitted to the vast majority of 'modern' TVRs?

Not so sure. My '99 Griff was fitted with Bilsteins from new? I should add that I am the second owner and have every invoice from new, with no evidence of a change of shocks before my ownership.

As much as I am a Bilstein fanboy from Ford days wink driven hard they just cant cope under damped and under sprung on standard cars although the springing can be sorted and no fault of the damper scratchchin in saying this I haven't tried the latest Billies my new old stock ones inc Eibach springs did not inspire confidence frown I have since defected to Gaz Mono's and although harder with 450Fr 400Rr springs handling is transformed and although firmer not teeth rattling hard but then I dont use wheel sizes with rubber bands for tyres either eek of course down bumpy B roads at speed the car still jitters about but they all do IMO, I was worried the springing may be too much but over 1k later I am still impressed and driven sedately I forget they are fitted although the stock suspension would be hard to beat here wink if good all round manners are to be preserved I would stick with the Billies yes not forgetting mine is not an everyday driver just my cents worth scratchchin

My car is a late 1996 facelift Chimaera and definitely had Bilsteins fitted, here they are back on the car last Sunday after having a six year lay up.



In addition to going the full hog and buying new biddies Ben Lang is also offering me a rebuild option on my originals, he can only do this if I genuinely have Bilstiens which I clearly do. This rebuild service can include a revalve to suit the proposed revised spring rates and the cutting of circlip grooves to give me the ride height adjustment.

According to Ben this rebuild option is available on all yellow bodied Bilstiens, what he can't do is rebuild the green body units which he told me were subject to a recall, Ben made no mention of HBE but I can qualify this point with him when we next speak.

I take Simon's point on the standard original Chimaera Bilsteins but what I'm being offered here is what Ben refers to TVR Mk4 specification, he's then proposing we take it one step further by building a set of these TVR Mk4 specification coil overs in a Chim/Griff damper body using Tuscan s springs and matched valving.

If I go the full hog I end up with the MK4 Chim/Griff Bilstein mono-tube/upside-down gas pressure technology dampers in brand new bodies complete with the correct road friendly rubber bushes and quality Eibach springs all custom built to Tuscan S specification.

Ben Lang worked at TVR and talking with him he was clearly involved in suspension development work alongside the Bilstein engineers TVR eventually contracted. Ben explained his time came after the Chimaera/Griffith years, while the Chim was still just in production when he joined all the development work had been done so he didn't actually work on the model. He seems to have been recruited to develop the suspension on the Tuscan S and Sagaris and he's suggesting the things learned during this development work can be retro installed into the bodies of the Chimaera/Griff Bilstein units.

The way see it is, if my basic unmodified 20 year old Bilsteins that have been sat in a box for the last 6 years can work so well then a set of brand new MK4 Chim/Griff Bilstein mono-tube/upside-down gas pressure technology dampers built to Tuscan S specification combined with the better drop link design we've been discussing here could give me a fantastic handling TVR that also has the compliant ride I'm looking for?

Best of all the proposed price even if I go with the "All New Bodies" option is a good chunk of money cheaper than Powers Performance Nitron comfort kit, they would actually sit somewhere right between the price of Nitrons and GGPs which makes a set of Ben's custom built road friendly but Tuscan S spec Bilsteins very tempting indeed.

If they work out as good as it sounds these Bilstiens being offered to me have to represent the best value going, all you really lose is the on car adjustability of the GGPs, Nitrons ect ect, but as I don't track the car I really don't think I need this feature. What I need is coil overs that just work and give me a nice ride and handling.

Surely if the Bilstiens are set up correctly from the outset I should never need to crawl under the car to wind an adjuster up & down in an attempt to get them just right, I spent ages doing this with my GGPs only to eventually admit to myself 13 clicks all around was the best compromise setting and I was best off just leaving them there.

I think we can safely say the Honda Accord 1998-03 links work on the front as a few guys on the forum seem to have fitted them now with no issues. I'm certain the TVR specialist havent had something specially made, the TVR market is just way too small for that. They've just found something that fits from another car and are selling them as special uprated TVR links at a premium.

On the rears you can use Mondeo estate links as Phased has but there may be some modification required? In the next day or so I should also be able to confirm if Nissan 200sx fronts serve as TVR Chimaera rears.

The spec & dimensions of these Nissan links seems to suggest they'll be a straight fit but there's a world of difference between Googling something online and actually holding the physical link in your hand and offering it up to the car.

My trial Nissan link is currently waiting for me to collect at the post office so I'll be picking it up later today.

From Ben Lang - Former Chief Chassis Engineer - TVR Design & Development.

In late 2004, following a nine year gap the decision was taken to reinstate Bilstein as OE damper supplier for all TVR models. Bilstein had traditionally supplied units for Griffith and Chimaera, but since 1995 the bulk of production units had been supplied by HBE. This encompassed Cerbera, Tuscan, Tamora and T350 models.

The motivation for the change was that Bilstein could offer better quality and more durable units backed up by assistance and input in the development of ride and handling. The first car to benefit from this was the Sagaris, followed in the summer of 2005 by the Tuscan 2 and Tuscan convertible. The level of development carried out on these cars far exceeded what had been carried out on previous models. The positive results achieved are evident in some of the road tests published in the motoring press. One of the main improvements, especially noticeable on Tuscan models, is the improvement in ride quality.

In addition to the development of the OE units, TVR was also obliged to develop spares units for older models originally equipped with HBE dampers, without any change of springs or anti-roll bars. Again, a marked improvement in ride and handling quality was experienced when compared with the original parts.




Chimpongas says.. "I'm going back to Bilsteins built specifically for 'Ol Gasbag' to the Mk2 Tuscan specification"

By the way Ben's credentials seem pretty watertight to me as following his time at TVR working on their final models (Mk2 Tuscan and the mighty Sagaris) he now works as Chief Chassis Engineer for The Ariel Motor Company, so I guess that means he works with Intrax these days more than Bilstein as he did in his TVR days but he clearly still retains his Bilstein contacts.

It seems Ben is developing the Ariel Atom by day and building new Bilstein suspension for some old LPG powered TVR by night wink

I've been very clear about the weight distribution difference between 'Ol Gasbag' and a standard Chimaera but this didn't seem to phase Ben one bit, actually I got the feeling he was relishing the challenge and he agreed that Chims and Griffs could do with a bit more rearward weight bias. I've also been clear I want a compliant ride combined with great handling, Ben seemed confident I'll get exactly that and all for a very reasonable real world price.

Here's hoping I finally get the fine handling and compliant ride I seek from my Chimaera.... scratchchin

I went through this exact scenario 18 months ago, my car had completed 36k miles on the original billies, they weren't leaking and worked well, however, as I had replaced/upgraded all other joints and bushes, I wanted to do the same with the suspension.
I looked at all options and as my car is used on the road, I opted for the mk4 billies from Ben Lang, once fitted, the handling of my car is night and day different, so I suspect my old billies were way past their best, even though they weren't leaking.

The 3 height adjustability is a bonus too smile

Fantastic feedback and just what I'm looking for.

Mk4 Billies from Ben Lang are my next TVR purchase, on paper they seem like they may offer the perfect balance between handling, ride quality and affordability for Chimaera owners who predominantly use their car on the road as I do?

Only time will tell if I've chosen well.. scratchchin

Another Bilstein user here smile
I scrounged a used set of yellow Bilsteins to get them refurbed via Ben, with the late Tuscan single rate rear springs, three circlip grooves to hold the spring seats, and the revalving. Fronts are still std springs but not sure if the front shocks are retuned. All new bushes throughout - note if you have the larger bush eyes on the shocks they're a heck of a lot more expensive to rebush than the smaller diameter ones, £28-odd vs well under a tenner each from memory.
Refurbing/retuning was substantially less than the Mk4 new price, and Ben is very easy to deal with.
Can't remember if my setup is now the same as the Mk4 spec or not, but it has made a definite difference to the previous standard 22k mile set up, and I'm not the worlds best driver/chassis analyst by a long way. Will corkscrew on big undulations which can catch me out but overall it feels less likely to want to kill me now.
Road use only for me, so I came to the conclusion that I want compliance and predictable handling (as far as possible on a budget with a bendy standard chassis cobbled together with old Ford bits) and most importantly decent longevity.
Compare a steel tubed Bilstein and some of these all-singing-all-dancing fully adjustable ally bodied units, and there's not much in it pricewise - why?
Money no object and I'd have a Sportmotive evo chassis please, with Intrax, Ohlins, top of the range Nitrons etc, but I'm more than happy with these Bilsteins although technically I suppose they still belong to ChilliWhizz - shhhh wink

Just out of curiosity, what height setting is the normal one to use with these new shocks? Mine are not fitted yet and they came set to the highest ride height, not sure what this will look like in reality?

Ok, so here's the answer we've all been waiting for...



Basically the distance between the lower bush saddle (washer) and the centre line of the ball joint is 60mm, so 10mm less that the 70mm measured on the Leven links.

I'm keen to understand the impacts of this 10mm, an anti roll bar is essentially a laterally mounted torsion bar that ties both lower wishbones together so one can act on the other.

The ARB bushes allow the ARB to rotate within them and as long as both links are the same length there will be no uneven loading, but in theory a shorter drop link would reduce the leverage on the ARB.

If I'm right and a shorter drop link offers less of a mechanical advantage over the anti roll bar (torsion bar) using the shorter link will be much the safe as fitting a stiffer ARB. In which case the 10mm shorter Nissan 200sx will deliver less rear roll than the Leven ones I removed?

I'll now put my theory out to the floor for debate.. coffee

Is that bolt long enough to go through the roll bar? Looks considerably shorter than the leven one...
