'98 Sport w/ California roof and Kompressor (Downing Atlanta Supercharger). The DASC easily fixes the only criticism I've ever heard about the ti--i.e. not enough power. I now have ~210hp (at the crank) in a 2800lb chassis which allows this "Budget M3" to keep up with (stock) E36 M3's on track straightaways as well as in the turns! ...and I still get 28-30 mpg around town!
BTW, I replaced the stock M-sport suspension, too. If you have an Active or Base and would like to upgrade the handling, please email me. Asking only $250 plus shipping for 4 lowering springs (~.75") and 4 shocks with ~75K one owner miles.
