Any tire besides a dedicated radial/DOT slick is going to struggle if you’re hammering it on a 650whp+ blower car. The simple physics of trying to instantly thrust a 4000lb car forward with that much torque means it’s going to knock the tires off in almost every instance. I do not believe that on these cars there’s many suspension options to increase grip once you’ve done all the suspension arms in the rear. Unless of course you want to switch to MRC or Viking coilovers.

In terms of tires the PS4 sucks at anything other than being an OK summer performance tire that lasts, is comfortable, and quiet. My Goodyear Supercar 3s hook up way better than my PS4s did (when they’re hot) and give far better steering feel and lateral performance. IMO you’ll want to ditch the PS4s ASAP and pick up at a minimum a GYSC3, or even better a Toyo R888, or Nitto NT555 RII. Just remember, even with those tires there’s a good chance you’ll spin a bit if you hammer it. It’s best to roll into it if you can. These cars have a lot of torque and are quite heavy as I previously mentioned. Good luck
