Does anyone have the stock hub dimensions? I have been looking around the interweb at vented rotors and calipers and man they want just way too much of my cash! Just because I own a BMW does not mean I am going to spend that much on a kit that should cost 1/2 as much as they are trying to sell.

I also build and sell parts for MR2s... I think it is time to start doing some BMW parts.

Not sure what's too much cash IYO, but I went with Bavauto front rotors for around $150/pr. Power discs are less but don't offer a rear rotor (hence my choice of bavauto). A common upgrade for our ti's is the larger and vented calipers/rotors of other e36 3 series. Have you considered that or are you looking at Brembo big brake kits or something?
