Put some AP’s on that monster of yours and you’ll be able to run better tire options on track, and save a ton of weight in the brakes/wheels/tires than regular M2C’s.

Thanks for the link. I had high hopes for the RE71R on track, but something about that tire and my GT4 and me didn't mix. I ended up destroying the center rib of the left front tread surface in one day at Lime Rock. Might have been overinflation--I was running about 32-33psi front hot, and some recommend as low as 30psi hot--but nonetheless disappointing. Back to the PSCup2 for now...

The 71R is a great track tire when it’s cold and wet out.

Altho, it’s a very easy tire to kill when it’s warm or hot, and it takes a lot of patience not to overheat it, which gets old after a while. Your pressures were fine, it’s just an easy tire to kill.

The Yoko is supposed to be much more durable at higher temps, but I don’t have first hand experience, yet.

I couldn’t find any 19” tires I thoroughly enjoyed on track, so back to the 18’s!

I have 18's, R888's and Brembo Monoblocs on my M3 which is perfect; I really like the 763M and 2NH brakes on the M2C and won't be changing them. If I wanted an upgrade over the RE71R I would go to R888R.

Tried them, wasn’t impressed. Less grip than 71R and life is just as short.

Also saw three 911s blowout rear R888R sidewalls in one weekend, with one almost going into the wall.

RE-71 center rib wears very quickly regardless of the car, that's a normal usage pattern. I'm normally at 35-36 hot.

Tons of options in this segment now. Falkens sound interesting. If they were noticeably cheaper and came in 19's (curse you beautiful M2C brakes!!) i'd give them a shot.

Good info. Nice to know I'm not alone in this with the RE71R.

Yowza!

A050 FTW, too bad we don't get it on this side of the pond.

I'm not sure I believe these tests. I bought some Hankooks based on a review that put them within 5% of MPSS for half the price. I got half the grip instead.

The RS4? They’ve never been known to be that grippy or fast, but they last a good bit longer than most tires in the category: https://www.tirerack.com/tires/tests...y.jsp?ttid=234

No, sorry about posting basically off-topic info. V12 vs MPSS, not track oriented like this test. I was just trying to say that tests in general need to be taken with a grain of salt.

Gotcha. Well, interestingly the fastest tire in this group also had the best road manners (A052), mostly bc of it’s ride comfort.

Btw, I find Tire Rack’s test to be pretty decent, even if they’re more street focused. Here are a couple with the V12 getting beaten by two tires that were beaten by the MPSS in a second review:

https://m.tirerack.com/tires/tests/t...b=ResultCharts
https://www.tirerack.com/tires/tests...y.jsp?ttid=148

As for MPSS vs MP4S, dry grip is negligibly better, but wet and cold grip of the 4S is a decent bit better. You won’t find that in the TR tests, tho.

I’m excited to try the A052 eventually. Looking forward to hearing some experiences on heavier cars.

I intended to pick some up a few weeks ago but then saw RS4 at 25% off at Tire Rack. I’ve been running them for the last year and really like them, so I couldn’t resist. Maybe I’ll get to the A052 late this year or at the start of the next season.

My wife has 5 days now on the A052. She’s in a 718 Cayman, so not really comparable for us, but they’re holding up well and probably have a couple days left. No tearing/chunking or overheating.

Outside shoulder is on the left in this photo.

Im really interested in trying out the RT660. For the price, you cant beat them and it's like just a bit under the RE71R in terms of rating. Too bad they dont make any 19s yet.

Hey ZM2 - I'm thinking about going with a similar setup as you for track (18" EC-7, still deciding on forged or not). I'm wondering if I can get your opinion on the difference if I switch from MPS4S (which I'm running now on my 19") to 18" A052? I've never run a dedicated track set before as I both street and track my MPS4S, but I figure if it's a big step up then it would be worth spending all the $$$.

This would be for HDPEs - I notice my MPS4S getting real greasy towards the 2nd half of the day - I'm assume this is due to the MPS4S's being street tires and not being able to handle high heat for long.

Yeah, that’s typical for 4S’s when they get hot on track. I still use them as my <40F & heavy rain track tire, tho.

Do you have camber plates installed? If not, you’ll kill any track tire really quickly without a proper track alignment.

As for the tire, two schools of thought: 1. If you’re still learning the limits of the car, a track tire with less grip may be a better intermediate step. 2. If you feel very comfortable with the car at the limit, get the A052 and take your level of “comfort” a couple notches higher.

For better, for worse, I tend to jump headfirst into things to try to learn quickly, so I’d opt for the A052 so you can learn its limits as a new baseline going forward.

Thanks for the insight! Good one on the camber plates... I wouldn't want to tear up my new tires immediately.

I am running the MP Coilovers, so I do have some slight camber, but definitely not enough as I notice more wear on the inner shoulder of my MPS4Ss. I'll take a look into camber plates, although I'm weighing the performance gain vs. potential warranty issues haha - I might have to get real good at swapping the camber plates in and out whenever I bring it in for warranty work.

I have roughly 10 HDPEs under my belt already, which probably isn't all that much, but I feel like I'm ready to step from MPS4Ss as I dislike only being able to get a good few laps per session before they start falling off.

10 HPDEs sounds about right to move away from the 4S's. There's only so much you can ask from them, and you'll just make them louder on the street if you keep tearing them up on track.

The camber plates will definitely pay for themselves, vs killing soft track tires prematurely.

Most dealers won't hassle you regarding warranty if you have camber plates on, but you may want to ask in the regional forum section for input on which local dealers are more "mod" friendly.

Just don't let the dealer do your track alignment. You should find a good local race shop, and those guys will be much better at dialing it in. As for settings, you'll find a ton of input in various threads, but let us know if you get confused on anything.

Yeah, the dealership I go to won't hassle me unless the warranty work is something related to the suspension, then they'll give me a hard time

I appreciate the advice!
