4.08 gears and Lightened Flywheel

Srm would slightly undershoot target if final drive is changed so there is still a slight jerk after clutch is let out...but your right hardly that big of a deal

Good discussion on the Gears. I want the extra jam, but I do not want to lose syn rev so I'm interested to see if there will be a solution.

If I were a vendor I could see this as being a good combo pack, gears and a Syn rev tune sold together.

Yes on this chuck , but I have also heard that although the overshoot is not bad, and that by raising the rev limiter by about 300 rpm it will essentially eliminate the issue. I have also heard that unfortunately the ECU starts to figure out that it is "missing the mark" so to say and can actually cause some other problems. It gets pretty vague at this point, and is all hearsay as far as I am concerned.

The ECUtek solution, yeah don't hold your breath.

Yeah I am looking at a decent set of pedals as a "real" solution. I completely hate our pedal configuration, the throttle is too far back and too narrow imo.

I want to go lighter flywheel myself for throttle response, but also because I feel like when I shift, I have to shift slowly so the RPM's will drop enough for a smooth engagement. Will a lighter flywheel drop RPM's faster too?

The light weight fly wheel will drop RPM quickly due to less rotational mass.

Just got my Nismo back from Zspeed with the Z1 clutch and lightened flywheel, plus the Zspeed CSC. All I can say is WOW. The Z just feels more alive and shifting is so much better IMHO. Also the feel of the clutch is so much closer to what I think it should have been from the factory.

I noticed quite a bite of improvement with a lightened flywheel. Both in the lack of surge in first, and muuuccchhh better throttle response. It's a bit chattier than the oem, but honestly not much. I had the southbend 12lb flywheel and the endurance disk/pp.

As got the gears...if you're staying n/a it's great, but you will likely lose s-mode functionality. If you plan in boosting the car, for gods sake don't go with 4.08 gears. Go taller if anything.

And go ahead and get the RJM clutch pedal. The helper spring is good, but nowhere near the RJM setup.
