My guess is you will not see much of difference. The main reason is because you don't have a flat floor and your rear bumper is a giant parachute. The diffuser would have to extend beyond the rear diff to be effective. This is why you see so many track cars with shaved bumpers. Just letting the air flow unimpeded by the bumper will create less drag and a small amount of downforce.

What are you struggling with in cornering and were is it happening, turn in, mid corner or exit? Also is it high speed turns above 60 or 70 mph, slow speed or all of the?

I just hoping it will take the rear end down under high speed braking and trail braking. I don’t like how it moves. High speed cornering is fine. I’ve gone flat footing around turn 9 @ R.A. And done 113 through bishops bend @ sebring. I mean turn in due tire and suspension work, it was all oem besides hotchkis front sway and spl end links. Corner exit I was on a oem diff with a diff cooler. Oem alignment. I was working with what I had, all my money was saving for this build.

Copy that! Sounds like you might be at the limit of what your Z can do given the tracks you drive on and no suspension upgrades. You need coilovers to help with stability and if you haven't done so remove or detach your rear sway bar and see if that helps.

To perfectly honest, I have spent the money for the rear diffuser to by quality suspension parts. That is where the benefits are at. I built my suspension before before I ever hit the track.

I ran no rear sway. When the car comes back I’ll be on swift springs, oem Nismo shocks, oem mid links, oem Nismo shocks, and full spl everything down to the bushings, knuckles, arms etc.... hopefully this will help. I’ll run oem alignment until I get used to the car, then I’ll take the car to speed syndicate for a track alignment, run street tires for a track day, then throw on the slicks. If I don’t run into any mechanical issues along the way

Why not just get the track alignment? The car is going to be totally new to you anyway and the track alignment will only make it handle better. I guess if you are just curious to see what the real difference is in the two alignment setups that's cool but other than that I don't see any benefit to driving a dedicated track car with a OEM setup. Anyway you are going to have a blast with it.

Driving it 10 hours to get picked up, or slight chance I have to drive it 18 hours to get it back home.

Plus I want to drive it on the streets when I first get the car back. It’s say long enough. I’m going to enjoy everything about, turning it on, pissing off my neighbors, filling it up with E, feeling all 7-800 HP. Might even do some roll racing or 1/2 mile event.

I have never run slicks either but that will be changing too!
