You can spend that easily on a decent set of wheels & coilovers
Exhaust £600
Plenum spacer £200
CAI £100
ECU and decent tune £3000
All in about £4k for 15bhp
Anyways, verma's asking about styling mods
IMO wheels & coilovers are more important to the way the car looks than a body kit
No matter how good a kit you go for, if you get the wrong wheels then it ruins the entire look
