Actually it is covered by 14.2.C, which has been partially quoted a few times:[QUOTE]Strut bars are permitted with all types of suspension.

 

Page 144 section 18.1-F. Subframe connectors are allowed, but each connector must be attached individually with out any lateral components attaching the two longitudinal frame rails. Subframe connectors may be bolted or welded.


which part of this do you not understand?

you state: "The Street Mod rules do not have any additional provisions to allow an X brace. The closest thing is 18.1.F, which allows subframe connectors. The subframe connectors can only be longitudinal and cannot connect transversely." where are you getting the verbage "The subframe connectors can only be longitudinal and cannot connect transversely." from this section(18.1 F)? That is not how it reads.

The Digrappa X brace which is what I have, which is one solid billett aluminum piece it is not 2 pieces connected together by lateral pieces. Am I just misunderstanding this or what?

 

the MUZ brace would be a good example of: 2 latteral pieces attached attached by two longitudinal frame rails.

 

To me, "without any lateral components attaching the two longitudinal frame rails" means that the brace cannot run across the car (lateral means sideways or transverse), only along one side of the car.

The X-brace has two attachment points on the same side of the car, so it can't be a strut bar. It also has lateral components that connect the two sides of the car, so it can't be a subframe connector.

It's not a big deal to me -- I don't run in your class or in your region, but if you really want to know what the rules are supposed to mean, you ought to ask on the Street Mod list or on the "Ask the SEB" section of sccaforums.com. It would really suck if, on the day you finally earned a trophy, it suddenly became worth it to one of your competitors to protest you.

One thing that is emphasized in the SM rules in the SCCA rulebook is not to get too carried away with liberal interpretations of the rules, but check first to see whether everyone (nationally, not just locally) sees it your way. That way you don't end up spending money for a mod that you later find out is illegal, the hard way.

 

I know 18.1-E and the problem with the mounts is right there. It says - "UNLIMITED as long as they use the original attachment points".

No matter that upper mounts come as a part of the coilover kit, they are not counted as part of the shock or spring. And where the shock bolts to the upper mount is counted as a suspension attachment point. Aftermarket pillow ball upper mounts = not original attachment point.

Example with the Miatas -> The Tein Flex coilover kits come like that - with its own upper mounts. They are currently illegal in SM2 unless you remove the the upper mount from the Tein kit and re-use the OEM Mazda non pillowball upper mount.

Of course you can run them if you want, but my thought was more that if you have these already you shouldn't worry about installing X brace too - since already someone can contest against you in SM2 if he wants ...

[B]I didn't replace them, they are already made this way. Again, it is only illegal if my commrads feel that this gave me an edge. This is a self-police sport. I clearly explained to every one at the Pro-Solo that the JIC came with pillow ball upper mount. I didn''t take the stock shock and modify them.

 

I have had the local region look at and evaluate the x-brace and suspension they did not see any problems with them. At the next meet I will have them evaluate it again.

 

I'm not "against" you on this, but you would really need to bring all these points up to the official, or he may not come up with the correct judgement. If someone protests you, they will be arguing one of these points, and the official may change his mind. It would really suck to have to hear from the official later "well I didn't think about regulation X.XX in THAT way...".

 

Oh, I will.

MX5,
"And where the shock bolts to the upper mount is counted as a suspension attachment point."

where is this stated in the Cestion 18?

 

Here is an email exchange I had today with the local Assistant Regional Executive:

Guntersmurf,

Thank you for helping me out here!
