i fitted the r+b shim kit to my 4x4 cossie, and it does make a difference, it seems to make the car more stable at speed , and i feel much more confident thriugh corners at speed.

but the best thing about it is...... the rear tyres dont wear on the inner edges anymore

when a standard cossie is stationary the rear wheels are almost parallel, and when it pulls off the rear wheels toe out which causes no end of problems ,

with the shim kit fitted the rear wheels have a stationary toe in, so when the car pulls off the rear wheels become parallel.
