Lowering mk4's serious stress on components
« on: 22 October 2008, 23:11 »
I've lowered my car on coilovers found that wishbone bushes are split. The thing is arms are only 6 months old and when looking at arms they look under serious stress pointing upwards. thinking about poly bushes but way arms look poly bushes would drop out. Anyone had probs with lowering there cars. mine's dropped about 60-70mm all round.

Wind it up to a 40mm drop IMO

lowering causes stress on componets because of altered geometry the only way to avoid it is to raise it closer to standard, large wheels also cause problems to bearings and bushes, upgrading the bushes will help but where does the stress go then?? through metal components and cracks are possible, but thats is unlikely unless it's seriously low and you have massive wheels

Audi TT wishbone's? or do you mean Audi TT front arm rear bushes? If Audi TT arms fit then i may go that way.

I spoke to balance motorsport he said betsway round it was to fit everything thing from audi tt if lowering 50+. What would car drive like if arb removed, they don't fit one to mk2 driver only gti. My old mk2 driver was on Jreg with 2.1lt tsr engine in and had no arb. lowered 40mm that drove well. will get pics up tomorrow take some in morning when get car on ramp.
