Cheers for your reply. The ratios are the same but I'm sure i read that the 4x4 cossie one is restricted to keep it to 2.4 turns lock to lock instead of the XR's 2.9 turns. On full lock I get a metal to metal grinding sound. Not actually sure what it is but I know its not good!

I'm running 215/40/16s and they don't seem to rub at all.
