I recently purchased a hatch STI, I’ve had a couple of WRX’s in the past. I’m really impressed with the car over all, I’ve been going to the Nurburgring ring last few years took one of the WRX which was awful previously running my Pulsar GTIR until reliability became an issue. I’m looking to improve a few bits before I go this year, what gearbox diff oils do people recommend I’ve always used millers in my Nissan. I also want a strut brace front and rear I know what brake set up to do, may be tempted to change the suspension should funds allow, Ive always liked KW anyone suggest an alternative?
