hi all i have an xr3i with 17s but it keeps grounding out on every bump,also i have spax fitted which are crap...ive been told today that coilovers wont help as you cant raise the suspension on the rears???will it make any difference if i switch wheel sizes as garage dont seem to think so due to the weight of the ice in the car???so here we go what can i do apart from ditching all the ice which i dont want to do...would be gratefull for any help with this.cheers.andy
