I just got my hands on a 2002.5' golf, for pretty cheap. I have already got 17' wheels and low profile z-rated tyres. I lowered it by 2 inches front and back, and dropped in a nice sub... I've got about $2000 dollars left to spend, and i want it to be spent purely on performance. I can do all the labour, (my dad's got a complete garage, complete with hydraulic lift) so all i need to do is to buy the parts.
You've already modded your car ... and don't know what engine is in it ... lol
Since its the Golf, not GTI, I assume its just the 2.0L .. if it's a TDI, have fun lol
an ECU chip, exhaust, and intake prolly run ~$1000 or maybe a bit more I'd think
In an unrelated question, I assume most/all mods void parts/all of one's warranty? I just bought a Golf with a 2-year warranty, but don't wanna kill it by modding immediately =\
