Going to Sonoma next weekend and need new tires. What should I get - RE71Rs or try MPSC2s with slightly wider front, like I alway wanted?

 

Re71r so you can help me figure out if they work! Lol

 

Good point. I'll ship them to sonoma so that I can lap on MPSC2s, do a quick pit-stop at lunch time and then lap on RE71R. MPSC2s have 4 days on them though.

 

What pressures would you recommend to start the experiments with?

 

Ben was running 32/33 hot, but don had me run 31/32 on his car.

 

I am not here, but I thought I'd leave this. GT3 is on Hoosiers. Puts the issue of power and course-dependence into perspective I think. I'll let you decide which car is which.

 

Air vents and steering wheel give it away

 

Well, I'm coming back to post my final thoughts on the RE71 295 rear tires on the GT3:

Unfortunately, I don't think it's a good combo. After making all the sway bar adjustments I could, the car continues to lack stability on corner entry. The back end breaks loose too easily from lack of rubber and the stretched tires in the rear. The car is still driveable, but the setup just isn't right.

 

try lower pressures in the rear. It got much better once I dropped it to 30-31 hot. I'll do a full writeup once I have a chance. Love the tires. The car was unbalanced still, but it was gripping really well.

 

They really just need to make the correct sizes!! Lots of GT3s hitting the track. Missed opportunity for sure

 

I have used the RE71R's for my last four track days. I am using them on 19" Forgeline wheels and thus am able to put the new 305's they started selling in August as well as 245's up front. I've been very happy with them so far and am throwing down some very good lap times. I'm running about 2 seconds slower than other experienced GT3 drivers running a 265F and 325R setup with Hoosiers on very technical twisty (2 minute) tracks like Buttonwillow and Chuckwalla. Shooting for about 31 front and 34 rear hot pressures. I have already bought another set so that I am ready to go when I need them, but will use 255's up front to try to dial out some of the cars natural understeer.

 

Yeah, 19" wheels and Re71r in proper oem width seems like a wining combo.

 

What times are you turning at BW?

 

My best time was a 1:55.58. Track config #13 CW

 

Please remind me which 19" wheels you guys are using with the RE71R.
