Guys, not being from a Subaru back ground but looing at picking one up I'm wondering what upgrades there are for the RB320, ideally I dont want to go with things that havent got a proven track record......happy to push the car up a few BHP as long as the pack is from a reliable seller....
Will happily look at any sites that you could recommend, going to have about £3.5k to spend on it initially.
