Ken,

With the ZCP option, you should be on 9" and 10" wheels instead of 8.5/9.5?

Thanks for the GRM link!

Regards,
Chuck

Correct for ZCP but I’m running a borrowed set of 18s.

Just got done with my first SCCA Track-Cross in this new 13’ Comp. I was running General G-Max RS tires which were way too slippery, so I went to 32/29psi hot at VIR today. Fronts rolled a decent amount.

Looking to get either a dedicated set of 18’s and tires for track duty, or just tires for my ZCP wheels. Any suggestions on what to get on the budget side? Or better to just shell out for some 71r’s and have a good time?

To answer your first inquiry, I ran any number of sets of tire setups with my 2.5 sets of competition wheels. The happy air pressures would range from 34-32 (less happy but grippy) front to as low as 26 rear with 28 most common. Obviously, this varied from Stones and Yoks but what I almost always found was that with my alignment, the Dinan bar, I always wanted a split of 4# staggered higher front to rear because it allowed for max accel mid-late apex. I know of two sets of FS legal Apex wheel/tire sets that are for sale. It may be the easy button or at least the easier button. I'm sure Ido is around here somewhere.

I am selling both my FS prepped car: https://www.m3post.com/forums/showthread.php?t=1702711

And two sets of FS legal wheels for it: https://www.m3post.com/forums/showpo...14&postcount=1

This car won FS at Nationals at the hands of my codriver. Comes with all the best FS bits on it and it's probably the lightest FS car in the country.

I would strongly encourage you to express your opinions with supported information concerning the widespread proposal concerning FS. I no longer have a dog in the fight, and don't have access to my prior letter in response, but you may be looking at some serious competition changes in 2021.

I recommended they switch the M3 into BS and move the super ponies into FS. Then the mustang owners who are whining will keep to themselves as they get smacked by new mustangs instead of bimmers. Problem solved.

I hear. One of the reasons I moved on from my car was all the whining and complaining on the forums.

Should've come over and played in STU

The real problem though IMO is not the M3 being better, its just that the other pony-cars have CAM to play in.
Moving down the other options from BS though probably wouldn't be so bad. Option 2 is just wishful thinking. I can't think of any affordable RWD 4-seat car I would want to drive besides an FRZ, and they already have a spec class.

thanks for the heads-up, haven't been following the SCCA drama recently.

Link for easy reference:

Haven't thought through Concept 1 yet but what a facking disaster #2 is.. who wants to ride the way-back machine to 2005? Why does anyone think a vintage street class for 20yr old cars that have either rotted away or been modified/molested beyond recognition by their 3rd and 4th owners by now is in anyone's best interests?

I actually like Concept 2 a lot, in theory, but as proposed, big meh. It's correct that ES is popular for the reasons of affordability and stability.

The problem is, it's also popular because it's almost a spec class, and the consumables are cheap, and the cars are just plain fun to autocross

The tires that a lot of the proposed Concept 2 cars need aren't all that cheap, they eat tires, t and there's a lot of unicorn-finding needed for some of those cars to be quickest permutation, followed by a lot of maintenance, followed by potentially still haven't the SAC decide to plop a brand new Mazda/Honda/Toyota in the class as a good "fit" which proceeds to be the fastness (GR Corolla parking only!) . Then there's the problem of narrow wheel, camber-free, relatively low power and soft sedan cars and their "fun" factor. Resounding meh for those reasons

Concept 1 is what I've been advocating (aka, shitposting on the internet) for. I have no idea why when Ford and GM go to the trouble fo making track handling packages they aren't classed to compete against eachother at the top of their Solo classes. It's dumb to make them potential maybe can-get-it-done in BS so long as there's no Tesla weirdness or whatever, just to avoid some annoyed base model owners etc. I love the E9xM but it's old and getting older, and it's had its shot, a longer shot than most, and capitalized on it, those victories will always be in the rulebook, AND 2019 was also an STU victory for the platform, which is exactly how the progression is supposed to work.

Also DS and FS are still often on top of eachother. Splitting a ton of hairs just to avoid sand in shorts

If the E9x M3 was removed from FS, would it suddenly 'fix' the class? A big part of the problem seems to be that no one is autocrossing stock prep Mustangs and Camaros anymore. Round here, seems like they all come from the dealer with CAM mods (not STP mods obviously) already installed.

The super ponies seem to fare for themselves just fine in BS. Maybe the answer is to wait for the next round of Pony car model updates to reassess what people want to drive? should be circa 2022, assuming they survive the SUV/CUV apocalypse.. in which case we better start arguing over where the Mach-E & Tesla Y fit.

I was going to sell after 2018 Nat's and was talked out of it when my letter was cited as the basis for withdrawing the move the M3 to BS proposal. Over breakfast multiple days at 2019 Nat's, conversations with higher ups made it pretty clear that they see FS as a class which is supposed to be won by Merica muscle cars and not a M3. I loved the car but the whining about classing starting in 2015 was tiresome. As much as STU is appealing, I didn't want to take all the comfort features out of the car to loose weight and make it competitive.

Speaking of STU, haven't seen much commentary on the M2 -> STU proposal. Is there a STU specific thread I'm missing?

M2 AutoX forum is in the F87 area -> https://f87.bimmerpost.com/forums/fo...play.php?f=660

There's a BS set-up thread on page 2 now but doesn't look like STU is on the radar over there.

No STU specific thread around here fsmtnbiker, tigermack, and myself are the only of us on here with STU-ish cars that I'm aware of.
I personally am maybe ok with OG M2 and f8x M3/4 coming down as long as they don't get unlimited boost. FBO within the rule changes proposed for turbo cars those cars could make quite a bit of power. But please please I'm all for bigger tires for all lol

No, to be honest I will probably go to ESP if I do nats this year. Having to scrounge around paddock to find A052s last year at the last second was stupid.

If the M2 is in STU, kiss it good bye as they've already ruled years ago boost can't be readily monitored which simply widens the gap the M2 has on the E92 M3. As for ESP, I guarantee that if a full fore build is prepped, it will be a one and done experience as it will blow ESP out of the water.

I would’ve agreed prior to the new camaro being lumped into ESP. Now I think it’s still a reasonable fit. The Camaro is wider and heavier but has a big power advantage and fits all the tire with no bodywork changes. I’m going to try to fit 315s under the stock bodywork so that if it ends us as a clarifi-change that it’s LP-ESP I’m still safe. 295s fit easy, 315 hoosiers are big boys though... we shall see.

Edit: as for the M2,3,4 and Supra into STU... it really depends on the tire rules. I wouldn’t expect to go any faster in a car with 500+ ft lbs at the wheels than one with 300ft lbs or less when stuck on <285 street tires.

I agree on the ESP thing. the Camaro/BMW battle should be a good one!

The issue with all the STU changes becomes opening it up to 305+ tires which was also included in the proposal. 285 with what's on the market tire wise (basically only one option) may need an update to 295, but going much bigger and those 500+ cars will put the power down better, and with the case of something like the M2, less weight.
