Default M6 guys 4.10,3.73 gear question

Ok ive been thinking about putting some gear in the car. When it is tuned and speedo is recalibrated what is the top MPH that your car seems to go how much topend have you guys lost in MPH. Ive taken mine up past 155 and rpms are still climbing this was with stock gears. Just wondering where the car would usually top out at

Hit 150 with my 4.10's. Was close to redline though in 5th. I took them out and went back to 3.42's and i like it better. In my opinion, unless you have a big cam and will spin it around 6900 do 3.73's

General rule of thumb is a4-3.73, m6-4.10.

I have 3.43 gears and 3200 stall works great !!!!! Try changing out your driveshaft to aluminum instead of steel
