Track Alignment Settings?

[BigBird]

Yup. I was aiming for -2.5 (middle adjustment). I think max settings would place it around -3.8 with pulled pins

when lowered and max setting with pins pulled, you can possible get over -4.

-3.8 is easily doable.

That seems like a wildly high pressure compared to what people run on other cars, is that really what you are going to move to?

This seems crazy high. I’m running V730s hot in the low to mid 30s generally, max. Am I doing it wrong?

I'll preface by saying I'm no expert.

But yes, absolutely I want to try these "wildly" high pressures. It's a free country; I can do what I want.

Kidding aside, they don't make V730s in 265/30/19, right? So I couldn't tell you if you're doing it wrong because I can only assume you're on 18s? But no, if I were to run this car on these tires at low 30s hot, I would absolutely slide the tire off the rim. It's happened before.

You could always try the chalk thing.

I currently run 19's in 255/35/19 and I run 18's in 275/35/18 - and then I ran the 20 inch stocks for awhile too, which are 245/30/20. I've driven all of these on the track at least once, and I've spent quite a bit of time reading about our platform and what people are doing on the track. I've also spent a lot of time talking to other Type R drivers at the track, and I regularly attend with 2 other CTR's. I've pulled in a lot of data points, but that is the real extent of my experience. I too am not even remotely an expert, and if your real answer is that you have no idea what reasonable track pressures actually are and you just want to try everything out, including "wildly" high pressures, I think it's a completely acceptable one and you can definitely do what you want. That being said, I've just never read about anyone running any of these wheel/tire dimensions at 50 PSI on really any tire to be honest. What tires are you on that are going to "slide the tire off the rim" at over 30 PSI hot? The video you linked is a guy on cold PS4S tires, which are basically like hockey pucks, and not really comparable to a warm tire, let alone a warm 200 TW tire. Eesh, video guy is also running those cold tires at 25 PSI. Ouch.

I remember in my Elantra N manual which also has PS4S, they recommended 35 psi hot for track use

I've run 71RS in 265/35/18 at 24psi cold (front), and 26psi cold (rear). No issues. Typically run the 265/35/19 SC3 at 26 cold front.
