Default t5 and 4.11 diff

Can anyone give me a idea of speed in each gear using standard t5 ratios and 4.11 final with 205/50 15s.

Is anyone running this?

Cheers

Im sure you could find a gear calculator on the web.

Standard ratio is 3.72 i believe or very near that.

Lower the ratio quicker the car but lower top end, higher the ratio higher the top endso decide what you want in the car.

What axle are you using? And what size wheels? I was using a 3.77 with a T5 before and it seemed alright. That was on 15-inch wheels with a 195/50/15 tyre.
