Gotcha.. I agree they're kinda funky looking.
What I'm looking for is for something to give me clearance when the suspension is compressed, so I don't touch the fender with the tire. I think I'll actually be ok with the current setup, but I'll find out soon enough.
By b/s I assume you mean bump-steer? So the spacer was necessary for you? And you are on stock K-member/stock A-arms, or aftermarket?
Do you currently get rubbing with compression?
Also, would you say the K-member is required to run the 10" RPF1's?
I've crunched some numbers, and realized that with my power level, and range, 3.55 is a good fit for local tracks. Going from 3.08 rear end will probably feel fairly stout.
