And you're right, I didn't even check wheel widths until last night when I started looking for tires. This was not a planned purchase and I didn't look into all the variables. I don't see it fitting into an ST class yet per the rulebook but maybe stx?! |

i'd bet they won't let the 235i go to STX and will be in STU since you will be able to overcome much of the issues noted above with wider wheels, coils and camber plates but good luck in that mix.

I'm pretty sure you have to request the M235i to be class in a "ST" class thru the SEB, they don't automatically do it. I did the same thing back then when I had a 370Z, tried to argue for STU but they put it in STR. You can try to argue for it to be in STX but like Z3papa says, I'm almost sure it will be STU.

The differential is a port-installed option now I believe, and as such is legal. That would be something to verify and look into as it will significantly help everything.
I thought the M235i had 7.5/8.5 wheels, but a quick google search says I'm mistaken. I wonder why they went so tiny - even the 135i had 7.5/8.5. |

I agree, however I bet the 228i goes to STX. That's what I'd pick for the class, if I wanted a non-twin. The door has already been opened by putting the 2015+ WRX there.

No argument there since the 128i is already in STX.

It probably needs to be clarified, as there was a tech bulletin in September which said it was dealer-installed and thus illegal. However, I think at that time it wasn't listed on the build screen. Edit: If you mouse-over the differential it talks about installers and such, so I actually don't think this clarifies anything.

I personally would not show up at an event with a diff previously ruled ineligible upon the assumption that if a protest were thrown, I could overcome it. Assuming you would not have to do the "tear down" and just admit it was an M LSD, you'd still have spent the time and $$ registering, traveling, staying at hotels, and then running, all of which could be dashed by their disagreement on sight whereas you could get the clarification ahead of time, and avoid much of this uncertainty. For those who have events 1-2 hours away, this is not as much of an inconvenience. For most of my Nat'l events last year, it was 5-6 hours one way dragging a trailer.

Should be pretty easy to document the M235i's LSD as port-installed if it is indeed port-installed. Documents should come with the car. Get protested, show documents, look at rulebook, protest goes away. Clarification by fastrack would help but the SEB can't issue a pronouncement on every M235i because some will be retrofits so what would be the point? If it's port-installed, it's legal, if it's a retrofit, it's not. There are lots of good reasons why this has to be the line in the sand, it's been this way for a long time. Documenting that is on the owner of the car. The SEB basically read the rule back to whoever wrote the letter, they didn't change the rule with that tech bulletin.
That said, I think the M235i is DOA in FS with no LSD or 50 LSD's. Not enough front wheel and not enough front wheel well, but the real killer would be no camber adjustment allowance that I know of? The E46 M3 is probably the worst front camber in FS and it can get a little over a degree, and has an 8" front wheel and weighs less than M235i, and the new Mustang and old Mustang both got ~-2 front, with a 9" front wheel and room for a big tire. I'm never one to discourage somebody from autocrossing an oddball car, but if the M235i can't get more than 1 degree of front camber, I wouldn't bother, it will just piss you off, just go to ST with it Setup wise, yes, big front bar is the biggest bang for your buck. Does F8x front bar work on F22? Quote:
Short answer, the front reservoirs are routed to, and rest in, the windshield drains and secured with fuel cell foam, this allows easy access without subjecting them to the heat of the engine bay, and the foam allows water to flow past without clogging the drains. The fronts have quick-disconnects so I just routed the lines along the harness runs Rears are just zip-tied to the carpet behind the wheel wells inside the trunk, routed the hoses through the vent panels behind each wheel well I think the MCS remotes are probably overkill for street class. I'd go with the non-remotes if I had it to do over again (they weren't available back in 2011 or whatever when I was one of the first to try anything semi-serious with the E9x M3 autocross-wise), for ease of install, ease of removal, and because the remotes are really better suited for a car that needs longer-run stability and heat resistance, neither of which is that important for a street/autocross car. That said, if you just want to burn money, they're awesome, and having the canisters up where you can get to them is very convenient for nitrogen pressure adjustments. And on Hoosiers, the car was magic. This thread makes me miss hoosiers.

On the BMWUSA web site, the LSD is not listed as an official option for the car. It is located in the "accessories" section. Not sure how that effects the outcome of the argument, but it states that it does not include installation costs, and that the final cost will depend on your "centers" (i.e. dealer as it refers to dealers as BMW centers) labor rate and that freight costs may be additional. I see nothing on here yet that does anything but support the notion that these are dealer installed accessories. It's likely a moot point anyway given the points made just above by Rich.

Yeah that's true. But if you have a document that says my LSD was installed in NJ before shipping to the dealer, it should be good. The definition is pretty clear, and all the SEB did in their "tech bulletin" was regurgitate it because they probably had no evidence (back in August) that the LSD could be port-installed. Now, if BMW is unwilling or unable to properly paper the car's history (which I doubt) that could be a problem. A port-installed part (as in, THIS part installed on THIS car) is considered a factory-installed part, regardless of whether or not it's also available through other channels. The logical leap people make is that if it's OK if port-installed, then it's just plain ok for everyone even if it's a retrofit, and that's to my knowledge not the case under the rules.

Oh ok, that's even better then. I didn't think the rules got any more granular than model year so yeah, retrofit to model year where a port-installed option was not available I thought was not OK under any circumstances

I don't know how I missed this! Buried in the M235 discussion I guess? Thanks for the response. Do you have any pictures of the routing? I'm interested in getting shocks with remotes -- but I can't say that I'm interested in dealing with the install. |
