i no but i just forget that you have to declare your alloys wouldn't it improve your braking in time of an accident though i can understand if i tried to claim for them and didn't declare them in the first place and well i was paying £1500 third party to insure my esco cos of my past so i don't think it'd of been 4 pounds for me but point taken and tbh that is it just wheels and K&N and that was only to try and improve my MPG the rest is standard exhaust everything so i'm no angel but nowhere near as bad as some people out there though
