Well, I do work for a major Bilstein distributor, as a test to see how it would work on the STi, so I didn't pay full price for the kit
Normally on these boards, people are all interested in power mods, and have very little interest in brakes/suspension/chassis, etc. Yes, it's a major mod, but doesn't have nearly the glory as a lot of the other mods get. (exhaust, intake, BOV, 20" chrome wheels, underbody pulsing neon kit, etc...) As an example, I currently own 3 cars, and have a grand total of zero car stereos.
Except for the unintended bodywork that the previous owner did to the car, the Porsche is the closest to stock of the cars I own, and is basically being repaired to stock specs. The other 944 I recently sold was the most modded car, as it was set up as an SCCA ITS car. The Miata runs in SSB, so there's not really much done to it. Except for the roll cage and tires, I probably have more $$$ in mods in the STi than in the Miata due to the rules package.
My budget isn't nearly what a lot of my competitors is (my $15k Miata against at least one $40k Miata), it's just that cars and racing are always what I've been into, and what I spend virtually all of my disposable income on.
