I have a manual C30 T5 R-design, currently has the Polestar tune. It also has the Polestar exhaust (which I don't think you guys got in the US), it's still a 2.5" system but it has a much sportier muffler.
At some stage I'm planning to do some upgrades.
Performance wise I'll probably get a downpipe and intercooler, and a tune.
For handling I'll probably go for Bilstein B8's with Eibach springs, but not 100% certain yet.
I'm also going to replace the clutch, probably with the Focus RS unit, and install an LSD.
I can't afford to do all these at once, but I'm struggling to decide on what to do first! I can probably afford to do one of the three (either performance, suspension or LSD) in the next few months.
Any suggestions would be great!
