The only Mustang I’ve ever owned that I didn’t change the gears out is my Boss... so I’m thinking a gear change in the GT350 would be a hot ticket.There's a thread over on one of the 6G forums bout an owner trying both 4.11 and even 4.56 gears. I'd be very tempted by the 4.56 option as 80mp is still only like 2700 in 6th, but it would make the lower gears more useable on the street.
