Im not doing competitions yet, but the more steering angle the better. I took the little plastic c clip limiters off (gave me 1 degree prob.) And put wheel spacers up front. One guy does make front LCA's that'll give you 65 deg. Of steering angle but the whole kit is $1200. Ima do that after coilovers and motor fix.
Anyway, ended up w/ welded diff. The spool the shop had was not right one. But It works great so far, no more 1 wheel peelin. Not too bad on the street as well. Tire skips on tight turns obviously, but It wont break loose in a corner without trying/clutch kicking. (On dry pavement) Im down on hp tho b/c of valve seal or piston ring on 1 or 2 cylinders.
