1999-01 Mustang Cobra
If you want a lightweight corner carver this may be your Mustang. The all aluminum 4.6 4V can make 400+hp with intake, exhaust, tuning and cams - enough power for street, autocross and open track days. Add some springs, shocks, camber plates and IRS bushings and the Cobra will out handle the euro cars. These cars are ageing so a Ford Racing shortblock and Tremec 6 speed just might be what you need.
