Should work fine, this was the diff that was fitted in the Tech 2 sports as standard i think. The tech1's were 3,64 if i am remembering the correct way round.

the 3.64 will give you a better top end 3.91 is a bit better on acceleration. Higher the number the lower the ratio (acceleration).

I use the 3:91 on my car and the acceleration is very good.

Top end not affected noticably, and I cough cough believe the INDICATED speed can reach 152 mph if you were cough cough chasing a pug lol !!!

A GPS may say a different speed but you dont lose much at all vice the 3:64
