As my clutch appears to be coming to the end of its useful life (creaking and the pedal going from easy to stiff half way down) I guess it's time to reach for the cheque book.

Anyone done the LWF upgrade on a TT?

Recommendations for a shock or shock and spring upgrade. I don't want any adjustments - I have enough trouble deciding on my seat position.

MOD500 has recently fitted the PSS9 suspension to his car.

I recently put bilstein HD's on mine. Seems to ride slightly better, but I don't really track it so I wasn't really bothered about making it stiffer etc.
Was tempted by PSS9's.

Although I like the odd track day, I'm sure that my time would be better spend steering my steed than tweaking it.

Have found the PSS 9 kit to be proper 'bo. I adjusted the front dampers to a stiffer setting for v-max and the front end bite was very good.......as I demonstrated to Clubsport, until I span on a corner!

Don't know about the LW fly wheel, I think DeR has one installed though.

I had adjustable suspension on my mini - i had a setting for going to the shops and another setting for taking a bird out etc.

With the pss-9 is it possible to set and forget for all road use and then another setting for track?

I remember 9M mentioning he doesn't use adjustables.

Yes, I run one damper setting for road, and one for Brunters. I only change the front dampers setting to a firmer one to try to stop understeer on the track. So Malton told me (they fitted the system)...too stiff a front setting on the road can cause the wheels to skip over bumps during cornering on less than good roads.

Thanks

What settings do you use front / back?

Have settings written down in car, will check tomorrow, but from memory:

The adjustment runs from 9 (soft) to 1 (hard) on each shock.

For the road I use:

8 front and 5 rear

On Sunday at Brunters I used:

6 front and 5 rear, though maybe the back could have been more stiff.

Regards camber, ride height, etc I will have to check the paper work and post tomorrow.

In general I have found even though the car sits quite a bit lower after installing the Bilstein kit the ride comfort is much better than the OE set up, though when you press on it feels much more controlled.


Thanks


Martyn.

PSS9 kit on mine too. If you do a search you should find my previous comments and experience from fitting it. Basically, if you want to keep near to the M0030 ride height, wind them up the maximum allowable height on the thread adjustment before fitting. Any lower than that and I'd never get it out of my garage!

In terms of adjustment, I've kept the dampers on the softest setting all round since fitting - haven't done a track day with her yet, but will be cranking up the stiffness when I do.

Overall the transformation is radical - the original dampers and springs had done 50k miles, and the car wallowed over dips and bumps, and in some places was alarming under braking because of it. I won't pretend that bumpy roads are a pleasure with the PSS9 kit, but you soon learn where the holes are!

Have just had the clutch done and went for the GT2 flywheel and clutch assembly. A bit of low revs "coffee grinder" noise, but the clutch works well and the engine does spin up a bit quicker. However, I suspect that the GT2 flywheel is not a REALLY lightweight one, because the fellows on Rennlist forums were moaning about how easy it was to stall their cars after the flywheel change - I've had no problems. Maybe theirs were skimmed versions.

I can only echo these comments.

Glad I'm not alone in the grinding department, this really is a dreadful racket but it's essential for resisting the bludgeoning effects of higher than normal power outputs.

Even so, I find it so harsh I wish I hadn't bothered: it would be preferable to fork out for more clutches than suffer that level of mechanical crudity.

My 57k 993 C4S has (eventually) just had suspension changed to PSS9. 9M did the fitting and set up, I let Robin do what he thought was best. I don't really anticipate doing track days at the moment so he set middle position front and back. Sounds like it's set a bit firmer than Martyns or Nels (my wife has become quite adept at pointing out potholes and drain covers in advance) so I may start experimenting. I have to say that there is a tremendous difference in the whole feel of the car (for the better), and it sits menacingly lower (even than standard 4S). I really like it. Having said that, we (the good lady and the 2 teenage moneyburners) took the 240 mile round trip to Walton Hall on Sunday but pressing on through the twisties 4-up I thought some extra damping on the back end may even have been in order. I'm pretty sure I will be making some adjustments before we head off on the 5 and a half hour trek to TV2005 (TMBs don't want to go in the Freelander, even though it means packing only one tub of hair gel!).
The Bilstein kit makes the car much more sure-footed and instills confidence (even on poorly surfaced Welsh roads), so If the funds are there, I would recommend it. If you are trying to be careful with the pennies, talk to Gert at Carnewal for the kit; even with fitting and alignment, overall cost was probably less than £1800 (but I can say that quite brazenly knowing that she doesn't read this forum!)

I have a 993TT with normal clutch (and Bilsteins).
I had a 993C4 previously which I had an uprated cluttch and lightweight flywheel fitted to.
Personally, although I quickly got used to this set up the mechanical noise at low revs and the stop start motoring convinces me in retrospect that I far prefer my Turbo set up. If you use your car every day like me then I would forget the flywheel.

I had the Bilstein HDs fitted earlier this year. They are kind of Adjustable but its at installation time. I hade mine lowered a little at the front (10mm). The ride quality is much improved over the original dampers. Like you I wanted no adjustment once on. They cost about £700 plus fitting. Got them from Gert and had them fitted by GTOne at the same time as new front wishbones with ployeurethane bushes - excellent.
