The Porsche guys like the RE 71R’s a lot. But those cars weigh 4-600 lbs less.

...I won't buy another set of RE71R.

I have tried Michelin PSS for several years and they are easily the best all around tire in terms of performance. The only trouble with PSS is soft sidewalls so you need a really wide tire and lots of camber to make them last up front, or square sizes to rotate often. Both would be ideal. The PS4S that replaced the PSS is supposedly better in that regard and they perform better and are similar price too. I think that should be a great tire to try if you've only been doing this a few times. Going to an RE 71R or similar tire with little experience is not great for developing skill or safety so I'd give the Michelin's some thought.
RE 71R will likely not last once you start pushing them to 10/10th. They were developed as an autoX tire and for lighter cars. They don't like open track or heavy cars. You are asking them to do both so they won't last. They are the stickiest tire based on local lap times at 200 tw rating, though. For what it's worth, I'm seriously considering trying them next season, but only because the 200 tw rating would put me in a lower class than anything else that has similar grip. And they likely won't last long lol.
My point was that you get the half inch of lowering without touching the suspension at all.Yeah idk if I'd want to be a half inch lower. I'm sure it would be okay, but haven't moved to coilovers yet so don't have that adjustability. I will probably go with a 35 anyways due to availability. To be honest I do love the meaty look of the 40 series as well.
Thanks man. Based on instructor feedback, and fellow driver feedback a stickier tire would definitely help me on track. I have moved out of instructed classes with the organizations I run with. I think my main push is I just bought some wheels for a good deal and would like to start looking at what tire to wrap them in. I'm definitely gonna finish out this year with my contis and 19s. Based on how they look after my last two events this year I may squeeze another event or two on them just to get more experience before I jump to the 200tw.
Oh yeah I'm not all about looks so not dead set on 275/40/18, but I do still street drive the car often. I'm lowered a bit over 2" on springs and koni yellows. I doubt the half inch would do too much to me, but still a concern as the frames of these cars sit way lower than the car looks. Which if I kept my 19s and used for dailying the car this wouldn't be a concern.
The more I look at the options out there I really don't even see many 274/40/18 tires. I'll definitely give the MPSS or MPS4S a thought though. Also have you done any rainy events on your tires? I do enjoy rainy events as a learning experience.
Yeah I'm running the Conti EC DWs and I've had so much fun at rainy events.
Going to cost a bit more initially , but moving up to bigger tires ( width wise ) will help you pick up some speed and should , theoretically last a little longer with more meat holding them up ---Apex 18x10.5 or 11s gives one a wealth of 200 TWR rubber donuts to try. BFGs are about as sticky on the Autocross course, but seemed to take a bit longer before they reach the slip sliding away phase of the RE71rs.
