I have an 03 WRX with PPP and 18" PFF-7 wheels. I am considering prodirve springs. Are they any good and what do they cost to have fitted.
Will fitting these springs cause my insurance rise?

Good springs, they are actually Eibachs set to Prodrive specs.
Provide a good balance between ride and handling, also gets rid of a lot of the 'wallowy' feeling.

Usually about £350/£400ish all in.

I would recommend. Had them fitted to my previous WRX 03 5 dr with 18s and the handling improved significantly. Ride is harder though. It also improved the way the car looked. Cost is around the £ 350 mark (excluding allignment) and may up your insurance a bit.

yup - recommeded.
