Was thinking of lowering 20mm, but read a few posts tonight saying it alters the geometry to the degree that the tyres wear unevenly, have you lowered yours?, what has happened with tyre wear?
Uneven tyre wear shouldn't take place if the suspension is in good condition (ie shocks and springs are ideally uprated to eibach prokit springs and koni sports adjustables, and all bushes are good), plus the car is tracking correctly (adjusting rear toe first before checking front is crucial for this).I've lowered a few GTV's for people; no-one has ever complained afterwards. Well, not about increased tyre wear, anyway...
Fact is GTV's suffer from uneven tyre wear in any case.
Make sure when your GTV is tracked the rear toe is done first (this is adjusted by the swivel rods on each side, connected from the subframe to the hub) then the fronts. If there is any issue with camber (which won't be much) a little compensation may be made by further toe adjustment.Thanks all, looks like it will be eibachs and proper adjustment afterwards then.
+!I put Eibach springs on mine, camber and tracking is all within tolerance, chops off the inside of front tyres. I adjusted the toe a bit to give a little less toe-out, and it has helped, the wear could be adjusted out but then the steering would be dead, so really its a choice between handling and wear. All of the suspension components are new. I think if the standard springs were put back the wear problem would disappear.
