As above. You'd have to change the hubs too. Better off going aftermarket.
I don't think its a straight swap, its something to do with the bolt spacing on the front hubs i think. Yours will be 54mm and cup has 60mm. (im pretty sure anyway)
You would be better buying some coilovers, k-tec ones look good and there a v-maxx as well, all round the £400 mark.
As in any aftermarket suspention.aftermarket meaning? buying the k-tec kit?
