Pat, the tubular reinforcements must be extended slightly so they meet the chassis rail. The attachment point is a rivnut with large washer underneath it to spread the load.

Excellent! You wouldn't happen to have a picture of that? Or know by how much they need to be extended?

The Golf is still trucking on. Now on 91k and about to go back to VW for its annual service.

I have a couple of maintenance bits to do: a front spring snapped so I'm replacing both with Sachs TT sport springs (OEM type not an after market lowering spring). The front ARB bushes were a bit softer than I'd like so I'm replacing those at the same time.


The mounts are the originals and not doing their job as well as they once were, so I'm replacing with OEM: a Febi engine mount (oil filled), and Lemforder gearbox mounts. I got them from ECP and Miser Auto. The parts come in the supplier boxes but are OEM with the VAG part numbers ground off.

How is the Golf coming along Mark?

I'm about to do a refresh of my 1.8t 180bhp Golf front end (all the rubber bits) so took a look back at this thread for some inspiration biggrin

This post prompted me to do the gearbox mount and dogbone on my car, had a surprisingly big effect on how refined it was and solved a 'clunk' on taking up drive that had been worrying me. Brilliant thread by the way, I've now just got to work on staying away from those remaps... biggrin

I'm posting to check if anyone would be interested in this car.

Two months ago it went to VW for a service, plus fuel, air, and cabin filters. It has brand new Brembo discs & pads all round, new Sachs front springs, lower arm bushes, ARB bushes, and ball joints (Lemforder) so the suspension and brakes are optimal. Conti sport contacts are good. Also a new MOT with no advisories.

It has not been used since and is stored in a dry place. SORN.

90k miles or thereabouts. Two former keepers (original owner then my other half). Serviced by VW.

Bit of an unusual one to price given the spec and standard of maintenance, but I had 2.4 in mind.

Bargain I would think, based on the amount of work you have put into it

Tempting, but at the wrong time for us annoyingly and the 2001 A3 we had left a bad impression. Though that was a bit of a dog really - this is totally different.

I've known you for years now, Max - if it is something you're interested in you can take it now and pay when you're ready. Just shoot me a PM within the next week before I formally advertise it.

Hi, do you still have the part information on these?

I've just had new front springs & dampers fitted on my MkIV GT TDI PD130 and it's sitting a bit high. The new front shocks are Bilstein B4 22-045751, unsure about the springs hence the reason for asking.

I did. It went to another PHer over a year ago; he went on to a 5 series so I don't know where it is now.

Thanks for that. Having got these my garage are recommending not to fit, on account of them being physically quite a bit shorter than the springs that came off the car. Can I ask how you arrived at using TT springs for a Golf and was it to lower the suspension or stay with stock height?

The springs taken off the car are marked 1 x Violet 1 x Yellow diamonds. They appear identical to the replacements the garage have actually fitted (which ECP swear are correct) but the problem is the car now sits 20mm higher at the front. The shocks have been replaced as well, for Bilstein B4's.

According to http://forums.tdiclub.com/showthread.php?t=308471 Violet/Yellow is 161lb/in. Bilstein list 37-155155 as their part for the TDI with sports suspension, and by email they tell me it's 23N/mm (131lb/in). That chart does not mark Violet/Yellow as 'S', but it does say PD130. It just doesn't add up. frown Sorry to hijack your thread.

I fitted TT suspension to lower the ride height / sharpen up the handling, which in original form was quite ungainly. I used Bilstein B4 front dampers and OEM Audi rear dampers, both for the FWD Mk1 TT with Sport suspension. The springs were the Sachs ones you've purchased - the part number is taken from my invoice. Details on page five: https://www.pistonheads.com/gassing/topic.asp?h=0&...

Bear in mind the PD130 came in model variants with Sports and standard suspension, and to add confusion throughout the the period the 130 was produced this actually changed in spec, with later cars having a different ARB setup and potentially spring rates than the earlier, softer cars.

It sounds like you had the original (Golf) sports suspension on yours.

They are from eBay and to my knowledge are legal. I think sidelight bulbs only become illegal if they are a silly colour.

I'm not in a rush to fit the Ferrari clutch as the car won't be in use again until next summer, so I've decided to perform some annual maintenance and improvements on the Golf as I'll feel the benefits of that work straight away - it in constant use.

The Golf has now covered 60k miles and as with most cars it is the point when a full suspension overhaul is required if spirited driving is to be enjoyed as much as it should be. The Gold recently passed its MOT without any advisories but there is a potential gulf between suspension suitable that passes an MOT and suspension which is still near optimal; the Mk4 has a benign setup as we know but I was finding an increased lack of precision at the rear end - likely beam bushes - and wear at the front end - likely lower arms.

I've been accruing a selection of parts to improve on whatever I take off. This involved eBay and a trip down to Norfolk to VAG breakers 'VAG Shack' - their prices are good and the service is excellent. I really recommend them.

TT lower arms - shot blasted and coated, billet inserts so I can run the early TT front bush, LEMFÖRDER bushes and ball joints. Old bushes left in for coating purposes. As per the M3 project I found that LEMFÖRDER are the OEM supplier to VW and most of their parts have the OEM markings and numbers on them, and some come with the VW logo ground off. They cost a fraction of the VW supplied identical equivalent.


TT hubs and spindles - shot blasted and coated, new OEM nuts, bolts, and disc splash shields to suit 312mm brakes, which I'll cover in a later update.


TT front and rear ARBs, LEMFÖRDER drop links and bushes. I got really lucky with these ARBs which were from a scrap TT but were both recently brand new OEM parts and the early pre-understeer type.


TT quick rack, LEMFÖRDER tie rods and ends, Cupra R ESP module coded ready for the quick rack, TT master cylinder and servo with two pressure sensors to suit the upgraded ESP program, and new OEM fluid and fluid port crush washers. I also went for Powerflex Black Series Polyurethane rack mount as I prefer solidly mounted steering racks.


The Cupra R and TT both run the same quick rack and upgraded ESP program, however for some reason the TT module - although still an MK60 - is wired very differently to the Cupra R, hence it makes more sense to get the latter. There are still wiring differences as I have found out, but nothing ridiculous. Here's my working out sheet in case it is of use to anyone else:


Bilstein B4. More sport biased than OEM but still comfortable.


TT facelift (>2001) springs which are 10mm lower than the launch versions. I decided that if I'm going to this trouble I may as well increase the spring rates slightly.


LEMFÖRDER front & rear top mounts, and front bearings.


New rear splash shields to suit the vented disc setup as I just trimmed my standard versions, and all new OEM fastenings for the front/rear suspension upgrades.


TT Roadster/3.2 front subframe which features the two additional reinforcement legs to tie it into the chassis - shot blasted and coated, lower strut brace from a BAM engined TT - shot blasted and coated, new OEM fastenings, and new OEM TT Roadster/3.2 subframe bushings, which are stiffer than the rest.


LEMFÖRDER Fabia VRS rear beam bushes. These have a built in limiter.


BAM S3 upper strut brace.


I haven't eradicated all the trim noises so I'll try to do a better job this time!


Electric window switches with chrome accents to match the Mk4/6 headlamp switch included with the auto headlight conversion kit.


My drivers side Recaro was looking tatty on the bolster so I was over the moon when I found a heated, cream, Recaro in amazing condition. It is incredibly hard to find leather Golf seats in acceptable condition let alone the driver’s side seat in cream leather! It's a bit grubby at the moment but there is a fantastic seat underneath that'll clean up like new.
mwstewart i need your help on steering rack upgrade.

Ahh, my car was fine so I didn't have to fit the module or investigate further. You may have luck on ukmkivs.
