regarding the spin at 100 mph... you’ve got the right tires... in sufficient sizes.....I’m wondering if you’re reaching a point (speed-wise) where lift is now becoming an issue. It is for me at 100 mph. much faster and I can feel the front end getting light. Additional aero is probably in the cards for me.
I plan on the Carbon fiber front spoiler (Larger) & rear diffuser. They will help settle down the rear when over 100mph.

It’s the torque. I believe getting the tires on the ground in the rear nearly identical to a drag racer is the ticket. When I moved closer last year, it was good/better, but I can get it even closer. I have a little bit of camber to go (I have it already set), not much toe from the last, but a bit. It don’t make sense. It should hold on. We will see. Get the Chinese disease over and I’ll come down all the way to Dallas early in the season.

I’m not doing that. I have been in the mid-160’s many laps now at BIR, and these are rock solid if they are dialed in correct. Could just buy a race car, that may be cheaper. This one must work for show, comfort on the street and as well as we can get it on the track. It will hook up. My ‘15 is a unicorn with stupid good power and it hung on at the very same track with PS4S 285’s, and even with its OEM Pirelli’s on many, many nasty laps. @sad tell us what a beast that little sucker is. This Redeye will either bust that base Hellcat’s sector time in that 1/2 + mile straight the first time out next year or me and @sad are going to have more in common with car ownership very soon.

Either way have fun with it. Hope to see you soon.

Back to the OPs original post, FWIW, try not matting the throttle. I have had similar confusion with what is going on with my Redeye, but have recently experimented with Sport mode, manual shift (shifter to the left and paddle shifting), and mash the throttle a bit. In third gear, 40ish mph on a 60° day and P-Zero summers, it will just roast the tires in a straight line. Probable better in fourth gear as it won't hit the limiter and shift. Be careful with TC/SC completely off. Lots of guys that have been burning rubber a long time have learned the expensive way. Good luck with controlling it on a road course with 1250hp!

Well I have also decided on Velgen SL-7's for the Redeye. 20x12 Rears and 20x11 fronts. I haven't seen a ton of choices for tires in 345/30's. Anybody tried anything other than the Cup2's?

Both PS4S and Cup 2’s. Get the PS4S.
I may even will use those for my next rear track set and not the Cup 2’s.

Why is that?
They are too particular compared to the PS4S. They don’t seem to give a big benefit over them either. May be the bigger car? I know everyone likes them on lighter machines. I’ll try them again until this set wears. I really need to think about why that last set shed its shoulders on the way into Tulsa last year. Going to really test that problem. I had to buy two for my front street set!! The taller tires just were scraping too much for me and I really like the rears. I also have a fresh front set for the track. So you can’t ding me for not trying. Ask me around the 4th.

Depends on your wheel size, and unfortunately what size the chosen model is made in, which opens other problems. I know it is not a big sin to mix Pilot Sport different models with each either front and back. I just like the PS4S over the Cup 2’s is my point. But because of the sizes made and what will specifically work, it is giving me problems with my street size selections up front. That is mainly due to the incorrect 11” wheel offset a supplier gave me and did not realize a 305/35 rubs. What is fun is when they basically ignore your feedback and 1) keep doing it, or 2) not even offer to make it right.

12 x 11 will be interesting. You mean an 11” wide front?
