with the longest straightest road I've ever found in IL or IA I've had my stock 96GT Auto to 147 and it took about seven miles to get their I'd say. maybe more? It doesn't handle the best at those speeds! very light
hmm thats weird... i've hit 140mph in a short distance, on the 5-North Fwy heading towards Cars&Coffee Saturday Morning car show, and it felt fine, i have a 1996 Mustang GT Convertible with 275/40ZR17's .
