Default SCCA Solo classing question

I have a hard time understanding the rule book for some reason.

Quote:
Equipment and/or specifications may be exchanged between
different years and models of a vehicle if (a) the item is standard
on the year/model from which it was taken, and (b) the years/
models are listed on the same line of Appendix A (Street Prepared
Classes). The updated/backdated part or the part to which
it is to be attached may not be altered, modified, machined or
otherwise changed to facilitate the updating/backdating allowance.
Standard factory installation methods, locations, and configurations
are allowed. The updating and/or backdating of
engines, transmissions or transaxles must be done as a unit;
component parts of these units may not be interchanged. Cars
not listed in the Street Prepared sections of Appendix A may not
be updated/backdated until approved by the SEB and published in
the official SCCA publication.
This is the section I'm having difficulty with. I've swapped over the majority of factory suspension parts from an 05 STI to my 98 RS, using exclusively factory mounting locations. So, am I still ok for SP or have I bumped myself into GT? (It's the difference between a streetable rollbar and a full cage here, fairly important :P)

The cars need to be listed on the same line in the appendix (maybe that's what your is about). Since the Sti and certain impreza, wrx model years are seperated in the appendix the parts on each are not interchangeable via UD/BD. They are different cars to the rule makers. What is open in *SP i.e. suspension, intake, fuel, steering wheels, seats, etc is not bound by UD/BD. What is restricted (or not clearly allowed in the *SP section) i.e. chassis, hubs, crossmembers, transmissions, complete engines, body parts, things I'm not thinking of, etc. are bound by UD/BD.

It depends on what you've changed. Suspension is basically open so if you've only swapped struts your good for *SP. If you've changed the crossmember, rack, and/or hubs or something your out.

Exactly what have you changed? I don't know what the majority of suspension parts means.

^^^ Exactly. Shocks, struts and springs are unrestriced in *SP, as long as they mount in the same manner, so those changes wouldn't effect the update/backdate rule that was quoted.

I'm not sure where you picked up the "GT class" from....I wouldn't worry about being bumped there. You don't need a rollbar to compete in autocross, but if you have one, it must comply with rules from the roadracing side of the SCCA. Pertinent sections of the GCR (roadracing rules) are listed in the Solo Rules for reference.

As long as you keep in mind that if the rules for a certain category (Stock, Street Prepared, , Street Touring, Prepared, Modified) do not allow it, you cannot do it. You may read threads where it's mentioned "If it doesn't say you can....you cant." That is how the Solo rules attempt to keep things simple, since we/they don't use a very thorough "scrutineering" operation. It's loosely based on honor, but random checks are made to ensure fair competition. Protests usually keep us honest too, as they can come up anywhere at any time.

Give the book some more time and ask more questions as they come up. Most likely someone has either done it, tried it, or found out it worked or didn't work.

Anyone that autoxes can answer almost any question about the rules for hillclimb if the driver is classing their car using the solo rules.

If you're using Solo rules to classify your car for Solo Trials (Solo rule book appendix D) in SP, then the answers that people gave you above are the answers you're looking for.

If you're using GCR rules, then I can't help.

Maybe this is what's tripping me up. In the rules for the hillcimb I'm interested in (Knox Mountain), it says this

Quote:
Cars competing in SP, and vintage cars raced before 1980 must have roll bars conforming to CACC GCR Appendix II, or Appendix L of the SCCA Solo events rules, although rollcages are highly recommended.
Cars competing in GTX, GTO, GTU classes must have roll cages complying with CACC GCR Appendix I,
But there doesn't seem to be a GT class listing in the SCCA rules. Argh.

But I guess it's safe to say that the suspension swap has put me out of SP class regardless, from what I've read.

That one?

CACC - Confederation of Car Clubs and the General Competition Rules (GCR's).

More research in a little while. Going home.

No, but it'd be easy for me to get it, Ive gone through 3 performance driving schools and 3 years of autocross.

What it boils down to, is that I'm not putting a cage into my car. I'll going to put a proper rollbar in tho. If I've put myself into a class that requires a cage, I won't compete in solo or hill climb, I'll just stick to drag and autox.

Hill Climbs are governed by time trial rules under SCCA:

Then your question has been answered. If they only refer to the SCCA rules in section 15... you're good to go since pretty much anything suspension wise (I'm assuming struts, springs, top hats, maybe even swaybars?) from a stock STi bolts right up and is legal to change.

You might be better off listing what you changed/swapped over and we can help, but if it's struts/springs/sways/tophats only... no problem.
no need. Legal.

He's in Canada. Their rules refer to certain parts within the SCCA rules, not the SCCA hillclimb rules.

Ahhh... missed that.

No. You're not legal for SP according to the Solo rules. Control arms, hubs, crossmembers are what prevent it from being legal (unless the part numbers from those pieces have superceded the part numbers found in the RS parts manual, and I don't think they have, especially the hubs... completely different).

Lateral links, coilovers and swaybars are legal.

Here you have a case of modding a car and then trying to race, instead of trying to race, and then prepping a car to the rules.

Well the primary usage of this car is for street, drag and autocross. Hillclimbs and solo sprints were only going to be an extra bonus. I wouldn't build a car for an event that only happens once a year in my neck of the woods

Thanks for your help tho!
