370Z Track Build Potential? - Compete with 911 GT3

FL 4Motion

As far as benchmarking the gt3, imo, the only choice for lsd is the os giken. And all clutch based lsds should run a diff cooler if pushed hard.

As far as helical gear lsds go, I still stand by it not being necessary to run a diff cooler, just change the fluid regularly and you’ll be gtg.

I’m a big believer in keeping stuff as low maintenance and simple as possible wherever possible, less stuff to break and ruin your day.

I will add one caveat to the above however, regarding the wavetrac, since it has carbon fiber plates in it and is a little bit of a hybrid type diff, a cooler might be helpful there, but for a traditional gear lsd like a torsen or quaife, I still say not necessary.
