Turn-in on these tires are amazing, they communicate well and you're able to play at the threshold of grip quite easily and if you overdo it, check up and they come back to life. Really fast when at ambient temperature, and they only get faster. Basically, you need this tire. No way another street tire can compete with this |

Cup 2's and DZ2's are very popular for serious track cars here in Germany. I can't afford them lol, but that's what people buy here.

Im quite happy with my new Dunlop Direzza ZII Star Spec's. Got to truly put them to the test yesterday on a hot track. The grip and responsiveness were unbelievable. My new suspension and brake pads also helped. The car is so much more predictable and stable now.
I hesitated for a while between the RE71R and the ZII SS, but had a great experience with the 1st gen ZII, which influenced my decision. I ran with the RE-11 the first year I tracked the 135i, and the tires were exceptional on the street, but not as responsive on the track (sidewalls were softer than the ZII and ZII-SS). Because the RE71R was just released this year, I wanted to wait for other feedback before comitting. But according to Kgolf, looks like the RE71R is up to the task, and probably similar to the behavior of ZII StarSpec. Sounds promising ...

In addition, I saw the design of the new R888R, they seems to be much more aggressive than the R888. They are closer to a slick tire. Really interested in them ! In addition, they are available here in France in 225/40/18 ...

Im asking to determine whether rcomp tires are really for you. Dont take this the wrong way. Im an instructor at two local clubs, and develop 440 ft-lbs at the wheels. Im quite satisfied with the Extreme Performance category tires. I drive my car hard, and my tires are at the cord after 8-9 months. The Dunlop Direzza ZII have been excellent, and the new Direzza ZII Star Specs (probably the RE71R's too) are simply exceptional on the track. Are you willing to accept r-comps that will last half as long, will not be very good in the rain, and will break traction with very little warning, which may throw your car in an uncontrollable spin? Dont want to come through as harsh - just some food for thought. I went through the same cycle as you did, and some experienced members on this board talked some sense into me, before making the mistake of going down the r-comp path. Maybe you can afford spending on a couple more sets of tires per year, or raising the risks of damaging your car. Not the case for me so I would rather play it safe ... To conclude, there are three types of slick that I know off: DOT legal r-comp tires can be used on the street (have minimal grooves for water evacuation such as Toyo R-888, Nitto NT01, Michelin Pilot Sport Cups, Yoko AO48, etc), dry r-comp tires (slicks such as Hoosier A6 or R6, that cannot be used on the street), wet r-comps (such as RADIAL WET H2O slicks that cannot be used on the street). Take care "mon ami Français" !

Great advice from the guys on this thread. I've used it and have now had one track day on my ZII*s. Amazing tire. Going from a PSS to ZII* is a whole different world. Turn in is so crisp. I was almost alarmed initially at first at how fast they react lol.
Just out of pure curiosity, has anyone had personal experience with the BFGoodrich Gforce Rival? I read some good on-track comparisons so was wondering if anyone here has used them. No good 18" tire options so it would be one of you guys on 17s.

Quite impressive if the RE-71R can handle that amount of grip ! The 1.18G are with which tires ? |

a couple of misunderstandings "mon pot" ...
#1 - Kgolf got a maximum/peak of 1.4g , and a constant/persistent 1.18g of cornering force, on the same RE-71R tire... #2 - What Im referring to when writing "without warning" is that r-comps will be lose grip all of a sudden, when you ask too much of them. Extreme Perf tires will start making noise before you lose complete grip ...

Here's the data from the tire.
Keep in mine, this is the 2nd run on the tire, EVER. No scrub in, no heat cycle. The tire is brand spanking new. Still settled for 3rd out of 178 |

So guys, little update !
I finally went to the Michelin Pilot Sport Cup 2 route which seem to be easier to drive as the Cup 1 and much more grippy. I bought a set of OZ Ultraleggera to a friend of mine too. I will review the tires this weekend after some track session

I have relatively little experience on tires for the 1er, but have run Star Specs on my old Stage three Subaru, and now the 71r's on Biene.
I have to say that the 71r's are and insane amount of grip and love them for the last three crosses. I mean these things are full potato stupid grip. They are significantly softer than a 200 rated tire though, and have no idea how SCCA allows them in Street classes. The break away is linear and predictable, and I didn't really notice them getting greasy with the heat. I haven't run them in the wet, but I have heard from others that they are still very good in that situation. Between the two types of Extreme performance tires I have tried, I prefer the 71r's, however they are expensive and wear quickly.

Any reviews of G-Force Rivals on 17s on a 1er? They seem to be matched against some of the top street extreme performance tires and their marketing looks good.

So, little review on the Cup 2 tires ... For the guys who said they are not crying when you're tracking them: they are screaming like other tires.
The grip is enormous ... Quite insane. At the begining, the Harry's Laptimer app shown us a cornering force of 1.56G ... And it was only the begining. After, the app failed, so I cannont say much more (I will try to have precise numbers). Contrary to the Michelin PSS, these Cup 2 tires are far better: after 1 hour of tracking, they were still able to run and fight against the time. I was very surprised ! I put 2.4bar (when they were hot) as Michelin recommanded between 2.3 and 2.5bar when the tire is hot. The ability of cornering is incredible and I'm very satisfied with these tires. In addition, the braking is considerable now (I have F2x M135i brakes with Endless MX72 pads): the Cup 2 help a lot the car to stop or to slow. For example, I arrived at the end of a straight line at 150-155kph (more or less 95mph), decided to brake at 50 meters before taking a very hard corner at 50kph (31mph). The car slowed down like nothing else ... Thanks my brakes and the Pilot Sport Cup 2 tires ! So, yeah, strongly recommended ! You will here a bit more of my review next week

No one has mentioned the RE11. I have lots of experience with them on my E90 and very much like them on the track and street. The RE11 used to be one of the best. I'm looking for a single set of street and track tires for my E82 that I won't be swapping out.
I'm currently running square MPSS 245/35-18 and am looking at 235/40-18 square options. In addition to tire rack test results and feedback from yourselves I'm looking at the total tread width.
If I consider your feedback, Tire Rack results, and the above I'm leaning towards the RE11, RE71Rs, or possibly the Direzzas. I'm hearing that the RE71Rs are great but can't get past the fact that their tread width is only 8 inches compared to the Direzza and my current MPSS which are both at 9. My current preferred of the three is the RE11 since I am very familiar with it and know exactly what I'm getting, has a tread width which is about the same as the stock tires, and doesn't have the tread noise that the Direzzas have. I had Direzza SS1s a couple years back on my wife's Audi and we ended up selling them because they were intolerably loud. I don't know if the SS2s are any better than the SS1s are but I'm not reading good things. Any additional thoughts from yourselves on the RE11 8.5 inch vs RE71R 8 inch observation.
