Pirelli DIABLO SUPERCORSA SP vs Bridgestone Potenza RE 71RS — Compared

“They are an amazing tire, both for autocross and track days. I'm currently running Falkens but my next track set will be RE71s for sure. Should be able to get a half second off my laps from what I've seen so far.”

“When I said 'they are more different than I expected,' the best way to describe that with one word is SMOOTH! These tires are smooth in all aspects. They are substantially quieter than the old 71R, maybe a 2 out of 10. After driving on two lane blacktops, I have not noticed any measurable gravel or other debris picked up at this point, definitely less than the 71R, maybe 50% reduction. Handling is the most important aspect for me personally and Bridgestone has hit a home run! Stopping fantastic and according to Bridgestone they are better on wet roads, IDK as I try to avoid driving in the rain. Steering is amazing and more sensitive! There is even a level of comfort that I did not expect for performance tires. Honestly, I am unable to come up with any negative. Five Stars! The post by jst2878 was spot on about them being a 'gift!' After break in greater than 300 miles, they just need to be hammered! After doing so yesterday, I have returned home for Pina Coladas & Pool this weekend!”

“Track tire fitment Just got some new Bridgestone Potenza RE-71rs in 245/40r18. I did my research on this subreddit and it seems like that will fit without rubbing/camber bolts. Does anyone know if the RE-71rs’ run wide cause they measure a full inch wider than the stock PS4s’, I’m just wondering now if I’ll need camber bolts. I’d prefer not, just want to throw them on and go. For reference they are being mounted onto a 18x8.5 +45 Enkei TS-V wheel. If anyone could offer insight cause I just can’t understand how they would fit but maybe I’m just over thinking it. Stock suspension by the way. I searched the sub and didn’t see anything with exact matching specs, only bigger and different tires. Tl;dr Will 245/40r18 Bridgestone Potenza RE-71rs’ fit on an 18x8.5 +45 wheel without clearance issues/adding other modifications (camber bolts) on our car? Thanks for any help! Read more”
