They messed up. I think you could run in STX due to the fact that you have a J30 diff. It changes the gear ratio from stock. However, nobody would know the difference so it could be OK to run in STS.

Just a correction: For Street Mod... brakes are unrestricted, meaning an e-brake is unnecessary, as far as my understanding of it goes (makes it easier for you to run a z32 rear brake, actually).

Nope.
Street Modified 18.1.C. Section 15.6 (Prepared Category, Brakes) applies, except for subsection 15.6.H. Guess what 15.6.H. says... The hand brake and operating mechanism may be removed. The rest of 15.6 allows any metal brake rotor/drum in original location, any caliper, any dual master cylinder, any proportioning device, any servo assist, any pads, any lines, and ducting (restricted). |

Going on 15.6, if any caliper can be used, then a caliper without the e-brake mechanism on it can also be used (i.e. Q45 or z32). Otherwise my car is illegal, using a different e-brake setup, having the original caliper removed. My guess is: since the rules that DO apply for 15.6 state that ANY caliper can be used, the e-brake does not need to be operational, if the e-brake caliper is taken out.

Interesting indeed.
The e-brake is integrated into the rear caliper, so replacing it with a caliper without an e-brake appears legal per the rules. However, the actuating mechanism and cables cannot be legally removed since they are not integrated into the caliper. But which comes first? The implied "You cannot remove the parking break." (which means you can't remove the stock caliper). Or the "any metal caliper may be used." (which means, in effect, you can remove the e-brake system in part). One of the great things about SM is the un-written "No Weenies Rule", which basically says that you'll be looked upon very negatively if you protest modification based on a slightly different interpretation of the rules that really has little effect on vehicle ability. If you don't want to rely on an un-written rule, you could write the SEB for clarification. If it means anything, I wouldn't protest you. ![]() |

here's the thing though: according to the wording, there is no rule saying you can or can't remove the parking brake, since the rule that states you CAN is excluded from SM rules (and so isn't an SM rule and should imply anything for SM). therefore, the clearly written rule, which states clearly that ANY caliper can be used, implies that a parking brake caliper does not need to be retained.

This Page is probably the most inclusive source on the net. But it's 2 years old, so some rules have been added, removed, or changed...and it doesn't include Prepared and Modified class rules (which likely won't matter to you anyway).
You have to purchase a rulebook if you need more than that page can give you. BTW, anybody with a '04 rulebook want to see if I need to add/remove/change anything in this guide? It's based off the '03 book. |

you sign up and register. or spectate at an event first. to get an idea of the cost associated with the respective classes.

I am also looking into joining solo2 and I know I have to join a team first so that I can get a points card. Anybody on here can let me know what team I can join? If you are interested in a new member for the 08 season please let me know. Just remember that I am new to this and have only done 1 auto x event at the California Speedway on the 18th of November.

Here's my Q: My car is basically stock besides the f/r STBs and 17" spec V rims -- no lowering springs. I ran in DSP, am I handicapping myself? Should i run in STS or STX?

As far as RUCAs being allowed in STS/STX, take a look at this:
"Camber kits may be installed on vehicles that do not have McPherson strut type suspensions." 240's have Mac Struts in the front but not the rear, so does that mean RUCAs are allowed because they are (obviously) not installed in the front? Or does it mean they are not allowed since the car as a whole IS equipped with mac struts? |

You can easily put on some stock rims & run GS. Of course, if you don't care about placing (which usually doesn't happen during the first year or so anyway), then run what you brung - figure out where you stand w/ respect to whatever class you eventually want to be in, then start modding your car toward the maximum limits of that class. Quote:
1) Don't install RUCA's - or just do the bushings + stock ruca's. 2) Ask your fellow competitors locally if they mind if you run that class w/ a RUCA - for the most part, no one cars unless you are in contention for 1st place. Most famous STS 240sx build up (stock ruca + bushings) - don't think this build up is on Zilvia, so linking to where I found it: http://forums.freshalloy.com/showthread.php?t=139581

You will just run most likely in SM class - no one is there handing out tickets, it's autox, not fast & furious midnight drag racing.

Yeah but I would drive my car to the event.
The reason I ask is because there is another racing organization here in San Diego. The cops hang out there and I have seen people get ticketed when they leave. No one goes to the race event anymore (that is just one of the reasons) but it still makes me weary. |
