I've just updated the OEM shocks and springs with the VWR offering, and so far i'm happy with it. Compared to the OEM which was 14 years old and on 144k miles i'd say the VWR kit is more comfortable, yet the car seems to have less body roll. It's lowered the car by 20mm rear and 25mm at the front which hasn't provided any ground clearance issues so far.
I've also replaced the top mounts for the Audi S1/S3 versions, and replaced the front bushes with the Superpro ALK kit.
At £540 i think the VWR kit is good value for money, compared to VW quoting £1250 to replace them for OEM. For all the above supplied and fitted by Indigo GT including a hunter 4 wheel alignment i paid £1500.
