I was just wondering if anybody had the measurements for how much should be considered a sensible and usable drop using BC coilovers and 18" wheels with 40 profile tyres? (im thinking its a long shot but i'll at least try)

Cheers.

im running 63.5cm on the front and 66cm on the rear from floor to the highest point of the arch

Cheers Aaron. I have measured mine and the front is 63cm but the back is 59.5 I dont think im going to need to go as high as 66 if i cut the arches - that lip on them sticks in quite far and with 225 tyres on there now its only a few mm away.

Angle grinder will be out this weekend and i'll post my results...

You could also pop a pm to Asi, he has the same coilovers and 18" wheels.
