Tire setup, mixing compounds?

[AlCap0ne]

Just blew out a set of rear tires after doing a few burnouts back to back, came across a set of Sport Cup 2s from a local listing in a 305/30/20 and had to pull the trigger.

My question is, I'm running PS4S's in the OEM size up front and wanted to mount these Cup 2s in the rear but I know there's a pretty big difference in compound.

Will I still be okay having PS4S's up front and SC2's in the rear?

BTW - I'm not too concerned with driving in the rain so please spare me the reminders about how terrible the SC2's are in the rain

You'll be just fine. Lost of people running R888r just in the back.

its ok, my setup 4S 265 front and CUP2 325 rear and before was with 315 R888R rear

That’s what I have now 265 /35/20 PS4S in front and 315/30/20 Toyo R888r in the rear

You will likely have more under-steer at the limit when cornering, but better grip in the rear for cornering and acceleration

325 rear??... Does it cause any problems with rubbing, clearance, speedometer, clocked miles, etc? But mostly rubbing? I am thinking going 305 as the stock is 295 using the same stock wheels. No issues?

i have aftermarket wheels 11.5 on rear, stock wheels 10.5 for M6

for stock wheels you can go Toyo R888R 315/30/20 or MP4S without any problems

Can you guys post pics of the R888r setups? I'm thinking about going from 325 Cup2 to 315 R888r on a 20x12

I am running a 325 R888r on a stock wheel without any issues.
