Default ZR1 tranny ratio

Hi all, for 2012, I'm plan to get some miles even to see what my bolt-on car are capable of. So to acheive a nice to end speed, I have ordered a complete ZR1 ratio to custom my TR6060. (Ask for Kevin at partstaxi.com)
Very very nice services and prices for all the parts envolved in my ratio swap.

My stock tr6060 are now opened, and I'm waiting my new parts.
So I will end up with my lowered ratio t-56 for drag race, and then my tr6060 with zr1 ratio good for street racing and top speed run.



Seb

Cool. It's always nice to have spares

But really for mile racing I think the main issue is to have something in the range of a .8 ratio for 5th gear instead of the .7 range.

Interestingly the CTS-V TR6060 (2009-2012) has this covered with 3.01, 2.07, 1.43, 1.00, .84, .57

Cheers, Paul.

Can the 5th and 6th ratios be upgraded on a T56?

Yep I can get you taken care of if you want to do just 5th & 6th, or all gears.

Sebastian - Thanks for the mention! Working on getting all this together for you, shouldn't be long. I'm looking forward to pics as you go through the build process


Thanks
