What weight spring and what size wastegate do you have?

I think it is a 7 or 8 lb.

If FI kits come with Tial then I’d guess you have the 1/2bar spring in them. That’s what I’m running.

Yup, the same.

1st and 2nd is still pretty scary.

It snaked a bit before straightening up the other day when I was coming out of a corner hard.

My GF shat her pants. But I told her I am learning the new car.

C. is about the last thing you should care about. Z people need to stop chasing the widest tire they can fit and focus more about how sticky the tire is. A 255mm drag radial will be a hell of a lot better than a 305mm Pilot sport.

You need to learn throttle control. When you feel the car spinning gently reduce throttle until it gains traction. Never fully take your foot of the gas, pretty much the worst thing you can do.

Can you elaborate on this? No else mentioned this in the thread, why is this so important?

It's called back pedaling. When you feel the rear coming loose. You lift a little on the gas pedal. Not all the way off. Until the rear reagains traction. Then you start pressing down again. If you lift all the way off. There is a good chance that the rear will whip around the other way. Causing brown stains in your underwear.

When you let off the gas, you change the loading of the suspension (load moves forward, similar to as if you had hit the brakes). You're already in a precarious position and a sudden change in handling can make things (much) worse. Probably other variables involved.

OK fair enough. This happend the other day when I took a hard exit out of a corner, the car started snaking a bit and instead of fully letting go of the acc. pedal like I normally would when I freak out, I only slightly lifted the pedal put still kept some throttle on and it made the car straighten out in a more controllable fashion.

But god damm, it is so easy to lose traction on this setup, I wish it was more predictable lol

It's a turbo car with some HP/TQ. They are very rewarding when driven properly. You just have to practice. It's not easy to learn but when you get it you will appreciate other folks skill even more.

Im prolly gonna need a good few laps at the track to learn the new power/tq.

THIS! Stop worshiping those damn pilot super sports. They're really not THAT good, just okay. Look at the Toyo R888R or Nitto NT01 if you want something that holds traction better in dry weather and still can handle well. Hell, even the Bridgestone RE-71R is fantastic and still keeps 200 treadwear (okay, barely, and just on paper). Drag radials if you're that desperate for traction, but don't expect them to handle turns all too well. Compound > tire size

PSS are a lot better on the street for every day driving then drag radials. Like you said. They don't handle turns too well. This will get him killed. R Comp tires NEED heat in them to work properly. You would have to drive at least at 80% level to keep some heat in them. All you are doing is heat cycling the tire too much on the street. Too much cycling and the tires become hard. R Comp tires don't work well in the rain either.
