I have a 05 WRX with PPP and don't want to invalidate the Subaru warranty or 'hammer' the insurance. Are there any mods I can do which fit this criteria. I'm thinking PPP springs & geometry set up, K & N or green cotton air filter, 'red stuff ' or similar brake pads with strut braces front and rear & lightened fly wheel. I would do some of this when the relevant parts were worn out e.g. brake pads & air filter. Your views/comments would be appreciated.

Cheers Barney.

 

Your dealer may not like your choice of pads if you damage the discs. The flywheel will invalidate your warranty, if they find it, which they will because your idle will be poor. If you fit the panel filter and you stuff your MAF then you'll kill the engine and they won't pay for that either.

IMO all the mods bar the prodrive springs and settings will not gain you any better performance. Wait until you are out of warranty and do some significant mods or dig deep now and stop faffing
