any comments on handling and what you liked v not? which diff are you running again?

The 370z was absolutely fabulous, even though we have just barely scratched the surface. In many ways, it handles very similar to the GT-R, except about 600lbs lighter, and 250whp less. As you can tell in the video, you just have to keep the revs way way up to keep the car moving along.

It took me a couple laps to realize there is no midrange and no turbos....LOL. But running the car repeatedly to 7500rpm was music to my ears. The car feels incredibly light on turn in, and exhibits zero body roll. It's extremely tossable, and easy to point the nose. There is a trace of oversteer on corner exit but nothing out of the ordinary. This is usually how we like our cars setup. The brakes are out of this world. I can honestly tell you these Trophy Series Race brakes from Stop Tech are the best I have ever used. Just breathing on the brakes is enough to snap your neck forward. It will completely overpower the ABS system and cause a slight hint of lock-up if you aren't ready for it. There is no pad knockback at all, with the full floating rotors and superb consistency and confidence under braking.

Roebling is handling track, rather than an HP track, so the times between a GT-R and 370Z well prepped should be fairly close. On something like VIR or Road Atlanta which are much higher speed tracks, I would expect a much greater delta between lap times.

We are running the Carbonetic 1.5 way LSD in the rear. I really love this diff...I would have hated this car had we retained the stock LSD for the test.

With respect to the question about the Porsches, they were definitely running at full tilt. Keep in mind, this was the Red Instructors group, so passing was permitted anywhere with a point. Usually once they saw me filling their mirrors, they moved over to let me pass by. This way, we avoid a drag race to the next corner. All good.

Happy to answer any more questions you all have.

Excellent stuff man! I'm going to have to call you about that diff once I start participating in some events this spring! If you dont mind could you give us a little insight into the alignment setup?

Sure can. We run about 1/8th inch toe-in rear, and 3/16th inch toe-out up front. Camber up front is -3.5 and rear camber is -2.3
