Hersch,
The 'adjustabilty' of the RF & other spaceframe cars can be made a lot more user friendly if the inner bushes of top/bottom wishbones are replaced with spherical bushes( similar to a rod end, but press in & retained by circlips ) and the chassis pickup points reworked so that all bolts run parallel to the car centerline. This also dictates that the top/wishbone ball joint be either a rod end or threaded type ball joint ( I think they use a Ford Transit tie rod end in the UK ) for camber adjustment.
With the pickup points reworked in this fashion the castor can be changed without affecting camber or wheelbase at the same time-by shifting the lower w/bone fwd & top w/bone rearward the castor can be increased without altering the wheelbase. All this is acheived by simply altering the spacer stack on each side of the spherical joints. Doing it in this manner virtually eliminates the possibility of the tire contacting the wheel arch or sponson at either lock limits.
[NB- this only works if the inner ends of w/bones re modded as above- will not work with plain bushes or nolathane etc]
