The final portions of the car Jason gave his attention to were the suspension and brakes. After all, he wanted his newfound pride and joy to hook hard at the track and run the best it could. First, let's check out the suspension, where up front, Jason threw in QA1 struts and springs, as well as performing a manual steering rack conversion. In the middle of the car is a pair of subframe connectors, while the hind end showcases Steeda upper and lower control arms and QA1 shocks and springs. For stopping power, Jason relies on Aerospace binders on all four corners. The Coupri rolls on BBS RK rims-the 18x8.5 fronts are wrapped in 255/40/18 Nitto shoes, while the 18x10 rears are shod in 305/35/18s. The back of the car benefits from mini-tubs that swallow up the large wheel/tire combo. If you think this car is a trailer queen, think again. Even though the rear tires screamed in agony, Jason shifted the Coupri to a best lap of 11.31 seconds at 136 mph.
"I just picked up a set of 315/30/18 Mickey Thompson drag radials that should easily get it into the 10.50s," Jason says. "The thing is, I built this car to run in the 9s. If I put in race gas and turn up the boost, the car should make 900 hp, which is more than enough to get it there. I think it's going to take me switching out the Tremec for an AOD automatic to do it, though. This way it eliminates my driving and makes accomplishing that task easier."
When all is said and done, only one phrase comes to mind when describing Jason's creation: It's one cool Coupri.
Take one small-block Ford,...
Take one small-block Ford, stroke it out to 347 ci, add a Turbonetics turbo, and the result is a bullet that will smoke the hides with the flick of the right foot.
From the rear, the Coupri...
From the rear, the Coupri looks just like the '88 Mustang it started out life as. That is, until you make your way around to the front end, where a nose from a '79 Mustang is mated to '84 Mercury Capri front fenders.
