i was thinking STS but it says up to 3.1L and mines a 3.2L so would that put me in STU???

Just off the top of my head, and with the assumption that you are running street tires, I'd point you towards STU. Some of those mods need more detail, as their are specific rules on what is allowed in ST in general. To be honest, I don't even think there is an STU competitor out there for us, so you might just be all alone to yourself. Other classes that may be considered is the SP classes or Street Mod (SM).

STU sounds like a good fit. I'm not sure about chassis stiffening, outside of strut tower bars, in street touring classes though.

Im with Kurt, STU would be most appropriate, however if the cross brace is welded, youre out to Street prepared, or Prepared classes. Xbrace only bolt on. The welded reinforcements may also toss you out. I believe all other mods to be in the spirit of Street Touring.

Remember, Under the provisions of Section 1.1 of these rules, Regions are free to allow any other version of the ST concept which meets their local needs.

Check out section 14 (ST) from the 2010 rules, if you find something you have that isnt allowed you're out. Although you may be able to convince the event chair to take into consideration Section 1.1 due to a small amount of active STU competitors.

Work on the driver, then worry about the car. If you are too fast, someone will inevitably chime in.

Good luck,

Ya the x brace is the only thing I was unsure about, it's not welded though,

so STU?, the tires are street, anything else that I can clarify please let me know

thanks for all the help fellas



Edit* ya I forgot about the sway reinforcements, those are probably an inch or so by no more that 3 inches to keep the sway bars from ripping out of their mounts, pretty common failure on e36s

Street Touring (within spirits):

• suspension point of connections (POC) must remain in the stock locations.
• Only bracing you can use are strut/shock tower bars.
• Sway bars are in their own section, but once again, mounting points are important.
• Tire width restrictions varies from class to class. 225 for me in STS, and I think in STX and STU it also varies if you are 2WD or AWD too.
• Rim width follows the same spirits as tire rules with max widths and varying from 2WD to AWD.
• Engine mods: Definitely I/H/E is allowable, but even then, some of the basic intake systems don't follow the AWESOME autocross rules . A good rule to remember is if it means messing around with the body of the car to make it fit, it's going to be illegal.
• No back date or update on cars, only allowable OE parts is if they were an option on that production year.
• Control Arms: You can upgrade one if your car is equipped with double wishbone suspension. I think this applies to all ST classes. Again, OE mounting points.
• Bushings: Some certain percentage about metal can only be used, or something like that, not too great in this area obviously. I know Poly bushings are legal for me.
• Aero: Search it
• Brakes: For sure, ST and STS you can only have OE size equipment, and no multipiece brake rotors. SS lines are good. I've seen an STX WRX have a BBK, as well as the STX RX8 (SportsCar) with an BBK, so I'll assume a BBK is allowed in STX and STU.
• Seats must weigh a minimum of 25lbs with mounting equipment. OE mounting points only.
• Steering wheel, if it came with an airbag, then aftermarket steering wheels are a no no (just don't check my car).

Note: If you begin to improve the rigidity of the chassis you are going deep into other classes, probably SM at least or even Prepared. Welding it on, for sure Prepared. Unless these were additions as OE options for that production year.

Hey guys thanks again for all the usefull input, after reading through the section 14.7 i just have another question. it says in the second sentence, "busching material, method of attachment, and locating points are unrestricted." since i altered the point of attachment does that classify it as chassis stiffining?

also i do believe that because my car was 8.5" wide wheels in the rear it would place me into the STX (2WD) category correct?

seriously please feel free to school me because ill be the first to tell you all im a complete n0oB at this

E36 M3's are specifically excluded from STX. From what you've stated, I think STU will fit pretty well. We can always look the car over at the events, and its not like we've had people fighting for STX/STU championships, who will get tweaked by someone with an extra brace here and there...


No harm no foul I say, I'm just here to have fun.

That is exactly the intention of Section 1.1 of the Solo Rules! It is more important to have fun, work on the loose nut behind the wheel, than penalize fellow competitors for trying out the club and its activities by playing capricious scrutineer.

With that said, I won't run the 350Z in STR due to 9.5 inch wheels until I get a couple that are legal. Just my choice, I doubt many would care unless a driver walks away with top times in the class several times...

ok so since we've been disussing this i've decided to add a few things to the car that i wasnt sure if i was gonna do or not. I've decided i might as well..

im gonna be swapping my intake manifold for another that has larger runners, and im also goin to be deleting my engine driven fan

im also adding an aluminum underpanel to replace the stock plastic one thats currently missing


so thats gonna certainly put me into street prepared, correct??

sorry to be such a PITA im just trying to make sure im in the right place


also what kind of cars is that gonna put me against??
