Last 3-4 Months I have worked on a friends/clients Mustang GT, Supercharged.
We upgraded it with a Magnaflow exhaust system, new set of brakes, headlamps, rearlights, koni shocks, springs from Ford Performance, new ignintion system from MSD, new rear axle system etc etc.
We have also given the car a full over servicing. And it now runs perfect!
About 500bhp to the rear wheels. And a sub 10 second car on the quarter mile, 9,22 seconds.
Also more upgrades will come! (On some of the pictures, the car runs on temporererly spring set for transport use only). New ones are now fitted.
