I just installed 4.30s gears and I really can't tell. If anybody else has done the gears would you please tell me what mph your car does in 5th at 3000, so I can compare. I also have 275/40/17s so that will make a difference. Thanks for the help

 

I am assuming by your tire size you have a 3rd. gen right?

I have 4.38's but I have a 1st gen., I go through the gears pretty quickly. The top of 4th gear is about 110mph for me, but I can check 5th at 3000rpms if it will help you.

 

Thanks but no, my rpm and mph would be the same as before. I'll check the mph against another car. Thanks
