1999 SS gear choices
I have a 99 camaro SS M6 and wonder what gear is in it. If i wanted to do 373's then how bad would it affect my 6th gear gas mileage over stock? Thanks, Brian Kaiser

Re: 1999 SS gear choices
You should have 3.42's, RPO code GU6. You won't loose much 6th gear gas mileage w/3.73's. To see what RPM's you'll be running go to www.f-body.org/gears/
