Is it feasible to use the roadster top front wishbone and the old book bottom wishbone.

The old books bottom bone is 72..mm shorter and I could then make the bottom rail that much wider each side so helping to line up the pivot points on the top, bottom and steering rack for adjusting out bump steer..

thanks

you seem to be trying to design OUT the camber change in roll that chris g spent so long trying to design IN.

the wishbones need to be different lengths to maintain contact patch as the suspension moves.

if you're building a roadster, build a roadster unless you know what you're doing otherwise. with a mk2 escort rack, there's near on no bump steer anyway if it's anything like the one i saw.
