Personally, I really like all the incremental improvements, performance or otherwise, with each modification I make. None of the changes are huge, but each one is noticeable and significant enough to put a smile on my face and make me not regret the money I just spent. Faster goodies: intake, Stock to stage 1, then throttle body and turbo outlet pipes, then downpipe then stage 2 tune (it was even noticeable difference before the tune), stock clutch to single mass flywheel, then light weight wheels, then fluidampr, then APR 2.1 to 2.4, then wagner intercooler. Handling goodies: VWR springs, then diesel geek shifter, then sway bars, then wheels and tires, then brake pads and SS brake lines, then unibrace UB, then tyrolsport brake stiffening kit and subframe kit. Other: kick ass stereo
. Next: water meth, then KO4.
Done all at once I would sh!t a brick if I saw what I've spent or worse, the wife would castrate me! Spread it out and it's like Christmas several times a year and each time you either go a little faster and or take that corner with more speed
!!
...my two cents.
