The FK Coilover Kits do look quite reasonable (compared to other kits on the market).
Looking at a good £450 for the FK's. For comparison Eibach Kit is £650 notes!!
.....add on to that the price of your chosen garage installing the kit on your car (for those not anticipating fitting the Kit themselves) - say an extra £100 at least.
Will create quite a hole in your wallet
but I suppose the look of a decently SLAMMED
Ibiza over one on standard springs/shocks = no comparison.
