Hi,
I just bought a set of these. the Racing ones. on the fronts there are some modifications you will need done to your original lower arms to retain full stearing lock. ill take some photo's of what ive done to correct this an post later today.
I've also had another slight problem that im trying to nut out right now. it appears left an right side of the vehicle are slightly different. which make no sence to me what so ever. might goto local tyre shop an pick there brains for a bit later. c if i can come up with an answer.
