you’re from ACT, Canberra area right?, just a few k’s from Sydney isn’t it?, why not head down to autostyle prestige and performance cars, they’ve got some of the best performance parts that I can think of, got my ordered from them at pretty reasonable prices, I don’t remember there location but I do know that its located in an area called hurstville on the Stoney Creek road (hey this might not be the right address even, I don’t live there, been to sydney a couple of times to visit a friend and he took me there) but I can tell you that they’re one of the best Tuners on the east side Australia.
Spending first on the interior seems like a ricery move to me, if you’re really going to work the engine then you gotta forget the fancy thousands and thousands of watts of I.C.E with flip down LCD’s every where, a nice black paint job on 18" Alloys (I don’t personally like Chromies) with some leather touches to the interior personally is more then enough for me atleast but every ones got there own taste, I’d personally recommend JDM style, much more aggressive yet very simple, head turning, light weight, etc…
and lastly is this a DIY project?
