Go with Waynne on this - insurers are more concerned about thief appeal than performance is my experience. Even changing a factory alloy for an aftermarket one of THE SAME SIZE can arouse interest, though could probably knock that aside fairly easily in a court and defend yourself by saying that you simply replaced like with like. After all, no-one cares if your car came with Dunlop tyres and you replaced with Continental or Bridgestone of the same size!
Interestingly I had a query with my insurer over swapping the 15" PEUGEOT alloy things on my 406 (205/60 15V) with 17" PEUGEOT alloy things (225/45 17W). They wanted another 120 quid a year. Guess what, I stuck with the 15" ones. Moreover the insurer charged me precisely nothing to allow a ECu remap from 136 to 192bhp. I suppose a remap is not visible or stealable.
There ya go! |
