Hi I have a 2001 3.8L Ford Mustang first 9 of vin 1FAFP4047 I was wondering what I could do in the rear end to safely increase my top speed I heard that the driveshafts are only rated for 120 and under or they explode what else should I replace that can’t handle 140 also what differential do I have and what could I change it to?
