TT regs?

[Joe freda]

I am currently preparing a car for TT competition in 2009. It is a 71 camaro Z-28. I seached the SCCA nat web site and they discussed TT's but did not reference any regs. Therefore, I would appreciate if you could help me with some questions.

What regulations govern the safety/prep of the car and car classification?

Is it the GCR, and classes are those listed in the GCR (i.e A sedan or GT-1)?


Thanks

There are basically two ways to go on the car preparation.

First is to prepare it totally for the Road Race class it would be in (A Sedan, GT, etc). THat will require the full rollcage, etc that a road race car has to have. It has to meet the requirements for Road Race with two exceptions - you can use arm restraints instead of the window net and the harnesses are good for 5 years (vice 2 years for RR). THe Road Race requirements are in the GCR.

Second is to prepare it to the SOLO Street Prepared rules plus the extra TT Safety equipment. In this case it would have to have the additional rollbar (not the full road race cage), fire extinguisher, race harnesses, etc. as the necessary safety equipment for TT. If you are going to use the car as a street driver or SOLO car, then the SP route is the best way for you to go. It is also the least expensive.

thanks for the info!

I have read the rules and have some additional questions.

First, The TT rules break events down into 4 levels. What levels are the TT events in the SE listed as??

Next, our level of car preparation will probably exceed what is allowed in SP. I am unfamilar with the street modified class but it seems like to next step up. Unless I missed it, the solo rules say very little about SM. Can someone fill me in about the basics to run this class.

Thanks

Here's a nice page with info that might help - http://www.rivergate5speed.com/scca/...als/index.html

Most of the competitive TT events in SEDiv are level 3 or 4, with one or two level 2 events mixed in, IIRC. There will also be a few level 1, or PDX events.

There are some catch-all classes, in SEDiv, for cars that exceed or otherwise don't fit the GCR or Solo classes. Maybe one of the current TTers can point you to those rules.

Joe,
I guess a question I need to ask you is are you going to run slicks or DOT tires (even r compound). If you decide to run slicks then your car prep goes up (as in full cage) and you would need to run GT1 or ASedan. If you go with DOT's then the SM or Street Prepared may be your gig and a supported roll bar is sufficent (it is your neck). SM tends to have your base model and a change of engine as long as it was made by the same manufacturer. What do you think makes the car illegal for SP?
Yes the rules are vague in some areas but the more we know about the car you have may help us get you the correct class.

[Joe freda]

I think the Cmaro will be illegal for SP because it will have a 4 link ford rear end, non stock five speed, non stock front frame with corvete Z07 suspension, 17 X 12 rims, dry sump, fuel cell, etc (I think you get the picture). The tires are hoosier DOT R compound race tires, but not slicks. The car will have a full cage, but will be totally street legal. If any of you are familar with the muscle car scene, it will basically be a "resto-mod".

The car will not meet the specs for GT-1 because of issues such as the doors will be functional and have door glass in them, and the 17 inch rims. Similarly it does not meet the strict rules for A sedan because it is an old camaro 1971, which is not allowed in AS.

Thats why I thought it should fall under the solo rules, maybe Street modified or C prepared.
I read the solo rules, and it sounded like any street legal sedan was allowed in SM, but offered few olther details. When I looked the the race results for SM, they were mostly import type cars.

Our goal is to run the car hard and have a good time. I'm sure the car will fit somewhere, so I don't want too hung up on the class. However, as I am building the car right now, so it would be good to know what class we are shooting for, if there are any special requirements.

If you get to constricted by all the different rules for all the different classes and it doesn't look like you fit in any, then there is always the SP_ classes. Not to be confused with the Solo 2 Street Prepared SP classes, these are production-based classes for cars that do not conform to SCCA Production or GT Rules.

SPO=Super Production Over (2.5 liters and over)
SPU=Super Production Under (less than 2.5 liters)

"...January 1997 this class was accepted Division wide as a catch all for closed wheel
vehicles from other road racing series and as a place for unique creations to have a venue
in which to get track time. Vehicles must not be other wise classed in the GCR and
Category Specifications. The displacement separation for Over (O) (2500cc and above)
and Under (U) (2499cc and below) [Effective January 2003 and reconfirmed July 2007]
and all Turbo or Supercharged vehicles will run in SP O. Series vehicles must conform to
configuration safety rules of the series (owners responsibility to show proof). All non
series vehicles must at a minimum comply with safety specifications as published in the
SCCA GCR and GT/Production Category specifications.

GCR Optional Regional-Only Classes
Super Production Class (SP) (Regional Class Only): Cars which exceed the preparation
limitations of the applicable Production or GT Specifications but which meet the general
regulations for GT category cars. This includes cars not listed in the GT or Production
spec pages, such as FIA homologated Production cars..."

Designed just for unclassible cars or for cars that it would take too much money/work to make fit into one of the 'normal' classes. It's a region-only type class (but used throughout the SEDivison. Only problem is I don't think it translates to a Club Racing class (in case you ever though about trying your hand at Club Racing), except 'maybe' ITE.

It kinda follows the GT-1 rules, especially on the safety items, but prep can be more than what is allowed in GT-1.

This is the class that a lot of the ex-NASCAR Road Race cars end up in, not to mention other racing venue cars like Rally, etc. So, depending on who else shows up, you could be dramatically out classed, but it is the catch-all class and if you're just out there to have fun and not looking for a Championship run, then this might be your best/only choice.

X Rat has some good info - the SPO and SPU classes were orignally brought into Regional Road Racing to have a place for cars meeting the rules of other organizations a place to play. Shafers SPO Camaro is an ex Trans Am car and some of the SPO I see Road Race were from ASA but those cars meet that past series rules (even NASA) and can be put into SPO. There are several SPO and SPU cars that road race in SARRC. Did your car get made following anyone elses rules if not we may be looking at SM with the DOT tires.

There's also the GTA class, another SEDiv class, which is where most of the stock cars fall, down here. In addition, I think there are some TT-only SEDiv classes, but I don't know where to find those rules.
