Thanks for all that info guys! Good stuff. Yes I'm doing it voluntarily....no yellow sticker (yet). I'd like to get it done "right" so that I can insure my car, and also not worry about trouble with cops.

Coilovers I'm not so worried about, I can just get Koni or Bilstein dampers with eibach springs....and that should be fine.

I know there's no guarantees, but I gather that with my Brembo (with HEL lines) conversion I should be fine without engineers report.....yeah?

Now with the sprintex kit, this is what they provide:


Sprintex says i'll still need to take it over the pits, but Tokyo says not required. So i'm confused.
