I have a standard r33 GTST. I am wanting to get into some Track days, Tarmac Rallys or the odd hill climb. Basically i want to do a bit of work to get some better times and was wondering what would have a greater improvement on lap times, Suspension or HorsePower? I am eventually going to do both sides of it but was either concidering a whiteline suspension kit or a 3inch exhaust and front mount, then raise the boost. 1/4 racing istnt o important to me at the moment.
Anyway i just wanted to know what side of the mods would give better lap times.
