Back in 1989 two Ford engineers, Arch Cothram and Lou Williams, supplied Car Craft magazine with SC they had modified to explore the limits of the then new MN-12 chassis. Their performance goals were to equal or surpass the current Corvette in acceleration, top speed, braking, handleing, and lateral acceleration numbers. They exceeded it in all areas. Car Craft was all over the engine mods and quarter mile performance but listed the suspension mods as "HD suspension" and noted the BBS 17x9 wheels with 275/40ZR17 tires. The ride height was 1.1" lower in the front and 0.8 in the rear (including the 0.4 from the tires). They managed to remove 180 lbs in spite of a 6-8 point roll bar install, total wieght was 3667 lbs. Weight distribution was improved from 57/43 to 54/56.
The car generated 0.935g lateral acceleration.
Other things of interest since many will be qurious are the quarter mile time of 13.61 at 102.04, 0 to 60 mph in 5.0 seconds, top speed over 160 mph, and would out stop a 1989 Corvette by 15 feet (thats a mile in brakeing).
Other mods: 3.8 liter with billet crank, 8.0:1 forged pistons, 282/292 degree cam, 125 cu.in. Eaton blower (engineering prototype for the M112) driven at 2.25:1, larger intercooler and tubes, 1.75" headers, no cats, 2.5" exhausts, Flowmaster mufflers, and a 3.55:1 rear axle.
