M coupe/roadster diff ratio?

1q2w3e4r · 10-08-2007, 12:46 AM

Hey guys, I was wondering if you could help a newbie out on the standard ratio of the M diff in the Z M Coupe/Roadster cars.

Im assuming its a 3.64 ratio from the E46 M3, but can't find any info around these parts. I'm interested in a 4.10 swap which is the reason for asking.

Z4M-coupe/roadster have 3.62. E46 M3 has 3.62 also.

Dinan offers a performance diff swap, i think it boosts torque by 8 percent in 1st gear. Check out their website.
