PFC 08 vs 11 for occasional HPDE

As far as the noise goes, concealing the sound of your exhaust may be a good thing in the F8x. I love this car but it sounds so terrible.

LOL

My experiences with the NT01 are limited to my E90 and E92. I haven't wasted any time with the CS screwing around with Nittos. Never again.

By the way the 265/295 RE71 setup on the stock CS wheels looks fine, I thought they'd look fat but it's ok

After I get my HAS installed, I'm going to run a fresh set of Nittos on an actual aggressive alignment and then give the RE71Rs or the Eagle F1 Super Sports a try.

Thanks, that's some great info on the tires. I'll scratch the nittos off the list since I was going to buy a tire to drive TO and FROM the track as well as at the track.

I'm looking at the sizing for the RE71R, looks like it comes in 265/35/19 and 285/35/19 (I don't see a 295 on tirerack)? It looks like these might fit on the stock 437 wheels if I pick up a used set of those?

I run 265/35/19 F and 285/35/19 rears on a spare set of 437's.
Great summer tire that has far more grip than PS4S, PS4S are currently on my other set of 437's that I will swap back on occasionally for long road trips.

I really wish they offered more size configurations for the 71s. It would be amazing if you could get 275/305 for an 18 inch wheel setup. 265/285/19 are still great though.

The 285 rear would be a much better fitment. I've actually run 255/275 combo on the F80 but now I'm using the stock CS wheels and the rear is a 20", so I'm forced to go to the 295

Agreed, although their 285/30/18 is quite wide. That's what I'd run on 11" rear if I had one

Pm your email and i'll send my alignment specs over. They are great

I ran both 255/265 and 275/285. Seemed like very marginal differences between the two (437M wheels). Turn-in quite nice with the 255 tho.

Thanks, I'll have to look into that.

-3 degrees? I ran -2.6 and it seemed like a little more could be beneficial. Same for the rear.

I find 305 to be a little excessive in the rear.

What pyro readings are you getting with -2.6?

Yup, it's all related to widths. If you have 9 fronts and 10 rears the ideal is 255/275 combo.
As you go adding tire width you need more wheel width to accommodate it.

In an ideal world I'd run a 10.5 front and 11 rear on the F8X. But I refuse to pay almost 500/wheel for flowforged stuff that should be 300/wheel. I'll wait until other ones are released.
On those wheels I'd run a 275 front and 285 rear RE71, then the same widths with R1's.

Now I'm running 265/295 on the CS only because I don't have any dedicated wheels for it and those were the only sizes for the CS wheels. The 255/275 combo is the E92 ZCP wheels but those weigh a lot so they're a pain to move around

I run -3 in the front at the track with appropriate toe. I can post the settings here but taking a flight soon so it'll be another time.

The rotors are as much of an upgrade as the calipers. I was hoping to keep the stock REAR F80 CS rotors and calipers but after 3 days the dust boots are charred right off

holy fu@#$, that was quite a BBK thread on M3post, great read. You know your brakes.

I'm right with ya. Only once have I ever had the pleasure of experiencing NT01s in the rain, never again. VIR full course, rain showers hit on certain sections of track and it was literally like driving on an ice skating rink. Not going to risk balling up my nice car to prove a point. I'd rather pull in, throw on my streets, slow the pace, and practice my technique.
