Default 5.1 Final Drive

I know j's racing sells it, but I suspect much like the 4.44 and 4.77 the 5.1 can be found from another mfgr. Anyone know what cars run it?

You can also customize your Quaife gear ratios. Did you pick too tall gears?

we have the lowest quaife gearset.
With 4.77's we have a top speed of 142, but we don't get any where near that on the ca tracks. 5.1 will give us 133 top speed.

ckit: yes you can but I think you buy the whole gear set and then we could swap some around. way simpler and cheaper to swap rearends,
