265/35R19 front and 295/30R20 for the rear is $1482. I'm reading they don't wear as well as the NT-01.

Pretty interesting conversation going on here. I think SYT_Shadow's first post is pretty spot on. Novices need no changes with the F80/F82. Camber plates + pads are definitely the next step, plenty of evidence of destroying tires with stock alignment and the stock pads quickly get overwhelmed.
The tire discussion is interesting. I'll be in a great position where I can gather some valuable data. I'll be trailering my car + spares, I have a ton of laps at my local track, the weather is pretty consistent in Colorado, and I plan on testing square + staggered wheel setups in 18". I won't be modifying this car past brakes, wheels, and the already installed camber plates, and without too much effort I could do back-to-back testing of tire sets. I'll do my best to log everything in a spreadsheet + notebook. I'll likely start wheel/tire testing in April/May, I've got an ej257 to install, an e82 rear subframe to replace, and then the f82 is back at the top of the queue. Quote:

If durability is a factor, Dunlop zII Star spec are slower than Re71r but consistent at the track and super durable MP4S is the stock tire on my model 3P and after 26k street miles they are at around 40% tread left so it’s a much more commuter oriented tire. |

When you also consider in the M2C brakes don't have removable caliper bridges at the front and weigh a ton they don't feel like much of an upgrade for track use. On the flip side they look fantastic, and feel excellent on the street with great pedal feel and are easy to modulate. Compared to the brakes put on M cars of the past (I'm looking at you E46!) they are light years ahead. |

Nice discussion here....
I've ran 19" 71R's (265 / 305) as dual-duty daily + track use the previous season. This is with ~ -2.8 or .9 camber up front. As they wore (I think down to about 4/32 or so), rain became significantly scarier during daily driving, in part related to the increased baseline tramlining due to the fairly aggressive negative camber. As this is my daily driver (which often includes hauling 2 kids around), this actually made me go for the 18" 275 / 305 NT01 setup for this coming season. I'm just going to suck it up and switch back and forth to 437M with stock PSS in between events (then eventually go to PS4S 265 /285 when those are toast). Will see how that goes. If anyone's going to be at NJMP this season let me know, would be fun to meet up. |

It just seems like we're repeating the same-old information to new track drivers without re-evaluating the current scene. It happens in this sub way too often and it's a bit frustrating to read. It not only happens with tires, but brake pads, maintenance intervals, etc. At some point you just gotta try it for yourself rather than relying on hearsay.
The RE71Rs are completely fine for daily driving, the noise level even with heavily unbalanced wear is tolerable for daily and/or road trips, and with minimal tread depth they are fine in heavy rain if cautiously driven. I've driven 3, 5, and 6 hr one-way trips with RE11s and RE71s over the past 3 yrs and neither were a problem. Those same sets of tires accumulated thousands of street miles between events/daily use without appreciable wear. Mind you, I wouldn't wanna do it with a 1990 Civic with no sound insulation, but with a BMW it's totally acceptable. Even the NT01 didn't seem all that bad noise wise, but they just don't inspire the same confidence level as true-street tires in adverse conditions. Maybe my ears are going bad?! If you gotta go with a smaller wheel option, could you make a 265/40 + 275-95/40/18 Hankook RS4 work on the APEX or OEM 18inch wheels? While not very wide, that might be your best bang for your buck while still offering great wear rates and commuting possibilities (daily and/or to-from the track). If I were to do it again, I would have tried using the Hankook or Nankang's over the Nittos from day one. |

You could always drive down here to the desert region! I was just at Streets Of Willow 2 weeks ago.

P.S. Just for the reference, I have 19" x9/10 OZ Hyper HLT wheels with RE-71R 265/35 and 285/35 tires and Pagid RSL29 pads for the track.

As soon as dealer sees obvious evidence of tracking they can deny to cover the affected items, but it's not the same as using the word 'flagged.' Interestingly even after they stopped giving me free pads, they did free brake fluid for me. One SA told me, "as long as you don't chip the car you are fine." |

If not, just stick to a front only BBK. Or stick to the OEM brakes and get a set of 19" track wheels, or just put RE71s on your stock wheels There's no need for a full BBK unless you're tracking very seriously. |

I'm not anti-RE71 by any means (or any other track tire alternative for that matter), but I am very pro dedicated track wheel/tire setup. Who wants to put track wear on a nice set of street tires, then live with the fallout for the other 350+ days a year that we aren't on the track ? That all said, in the end, it's good to have choices. It's what allows us as individuals to decide on a product that best meets our personal criteria. For me personally, I try to balance ultimate performance vs cost/benefit. Long term consumables cost is a very important factor to me, more important then shaving a few tenths, as it has a very big impact on the number of track days I potentially do in a year. If RE71s were the same cost, then sure, I'd run them, if no other other reason then it would be nice to not have to pit in and switch back to street tires if it starts to rain. Neither of the tire options being discussed here are shit track tires, so I just don't think labeling them as good/bad is helpful. Trade-offs any direction you choose to go, having realistic conversations about pros/cons about each option is what helps the community learn

Even RE-71Rs on my Miata are on dedicated track wheels and I only drive them on street on a way to track because like the you said you want to protect street tires, as well as I don't want to drive the RE-71Rs daily and wear/heat cycle them out.
