Hey Wagz, I was wondering if you ever considered putting a really good traction control on your Z? RACELOGIC is really big in the BMW community with turboed/supercharged cars. (http://www.racelogic.co.uk/traction.htm) It's not just some factory piece of crap that just pulls fuel and timing. It runs off of the ABS sensors and senses when some wheels are spinning faster then the others. It has an adjustable percentage of slipping that'll be allowed (i.e. 10% slip allows the wheels to just lightly break loose). Supra guys are starting to use it more and more because they put it on 0% slip at the track and floor it. It's sounds weird when it engages (Kinda like a bunch of really quick misfires) but you're still accelerating. Plus you can get a bunch of cool options like lauch control and shit like that. I know you are planning on selling it, but it's just an idea to help get the tires on the pavement.
