My AIS friends,

The powers that be are receptive to members of this class (and hopefully past and current officials) revising last years Super Stock Rules. It’s not guaranteed any changes will be made. They really want to make sure that the drivers are aware that nothing we post is definitely going to be used in the creation/ revision of the rules, but they will listen. Personally, I think if done well and stay within the intent of the rules, they would appreciate the help, and we’ll see some of our recommendations adopted. I can’t speak for the other classes, but if this works for the SS class, maybe it will work in the other classes. We can be the guinea pigs, but the way I see it we have nothing to lose and a lot to gain. For those who think this is a complete waste of time, that’s fine, but your future complaints about the rules will likely fall on deaf ears if you don’t like the rules.

I will post sections of the 2009 SS Rules. We can all discuss them, working our way through each section, and revise as necessary. Then we can keep adding each newly edited section to the original post, eventually “building” a completely revised edition to present to Paul and Rob.

It appears that the majority of the teams do have access to this forum, so I think we should have a representative number of teams to do a good job on the project. If anyone knows of any team members that don’t have internet access please talk with them and get their input too. This whole project will only be as good as the input.

If we can work through this without too many “distractions”, I don’t see why we can’t finish a revision ready for presentation in 2-3 weeks.

I only ask that everyone keep an open mind and please realize there is no way on this green earth that each rule will be 100% of what each individual team wants. There will be some compromises. It doesn’t hurt to think a little outside the box, or use other tracks rules for guidance either, we shouldn’t have to reinvent the wheel.

As you can see, I posted the first few sections of our rules before this post. I will go back and add revisions to the original post to keep building the rules. This will keep the rules at the top of this post so watching the progress of “rebuilding” should be easier.

Wish us luck,
Steve Burton, AIS SS #10

For starters, I see a potential grey area....

3.2. Not Eligible – No convertibles, T-tops, mini-vans, or station wagons.

Just to avoid any questions, should we add; no trucks and no independent rear suspensions. (Stole it from DIRTcar Street Stock Rules!)

I actually had access to a damaged corvette chassis and asked Rob if it would be a legal chassis to build up for the SS class. He thought it could be if I replaced the IRS with a live axle which loses all the benefits of running a corvette! Technically by the 2009 rules corvettes would be a legal with the IRS.... definite gray area!
Steve Burton, AIS SS #10

Thats a good idea. Smart thinkin.

Hello Gang,

Let's keep chugging along.

Section 4 - Bodies draft is posted. I'm sorry but it was easier to just start with a clean sheet of paper. You may have to have a set of the 2009 rules in hand to make sure we catch everything here. Again this is a collection of other tracks rules that seem applicable to us to and help eliminate those grey areas. Let's get everyone's input. Only 7 more sections after this!

Steve Burton, IS SS #10

I say we add a rule to have everyone that is planning on running a chevrolet this season go get a mandatory professional evaluation of their mental health because obviously something is not quite right upstairs. Did you hear enough from the ford guys yet ben? LOL!!

4.8. Fords- All ford bodies must include OEM rust for the original year make and model.

Seriously though I think the body rules Steve has posted are better and more specific than the ones we had for 2009.

Section 5 posted.

Hey, Tommy you're awake. I thought you already started your hibernation! LOL

Ben, that rust thing is serious stuff. I was always worried I wouldn't make minimum weight in that first Camaro I raced. Every time I got hit, I'd swear I'd loose 5 pounds of rust!!!

Steve Burton, AIS SS #10

Section 6 posted.

I need to get a real job.....my staff hasn't seen me work this hard on anything in a long time! LOL

I think that the worst of the most controversial stuff. Enjoy....my beer is calling me.

Steve Burton, AIS SS #10

http://www.johnsonchassis.com/CATALOG.html, hey guys, this is a link to Johnson chassis take a look at it .they have stock oem dimension and weight clips, frame sections for metric gm cars, I gave all the info to the tech guy at the last race to see if it could be approved for next year seeing how my front clip is bent and I didnt have much luck finding a replacement in any junkyard that wasnt already bent or too rotted to useits a little pricey at first at $675 but after you put it on all parts of the clip can be ordered in pieces so you dont have to replace the whole thing, sorry to all two of the Ford guys but they dont offer any parts for you but someone else probably does, I will check it out. The tech guy said he would probably allow it but wanted to investigate it more before making a decision, I think it would benefit us all to get this allowed in the rules as parts are getting near impossible to find anymore.. Scott

FOR ALL YOU FORD FREAKS. Howe makes a fabricated front clip replacement part #358-8-01, weight is 61 lbs dont know what stock weight is but is an f car replacement clip , here is the discription from Howes site.... The LLM front frame is made to directly replace the stock F-car front frame that is slowly disappearing from salvage yards. Made with tough 2"x4" tubing main rails to retain the durability of a stock frame. Accepts stock lowers & steering, conventional springs and a 3rd design sway bar. Engine mounts are slotted for 0" to 1" of set back. Inspection tags are welded to the top of the rails (shown in red). maybe you could lobby for this alsoif it is the same weight as stock, I didnt want you guys to feel left out!

All the Super Stock Rules sections are now edited and posted. Sorry, I just got on a roll and couldn’t stop. Understand this is only a draft, so please don’t think any of this is cast in stone. I just wanted to put something together that made reading sense to all of us, now we have to work on the technical and practical sense. Remember, we still have to present it to Paul and Rob for possible approval, be it all, part, or none. So let’s put a little more spit and polish on this and see if we can get a clear cut set of rules.

Steve Burton, AIS SS #10

4.3. Spoilers – A rear spoiler is allowed with a maximum 4.0” (inches) of material exposed to airflow and no wider than 60.0”. All spoilers must follow the contour of the rear bodywork.

this rule was change before the 2009 season from a 6in. spoiler in the 2008, I would lkie to go back to the 6in. rule
we are not running at speeds that create a lot of down force so a 4in. spoiler was almost useless. Tommy had a tall spoiler at the last race and he was fast, I believe that would be a big help for all competetors to make for a faster class !

I know this is not a grey area or anything but I saw it and wanted to put in my 2-cents

section 5.1 - I feel needs to be reworded as there is probably not a car in the lineup that hasn't relocated some of these mounting points

5.1. Frame Construction:
All spring, swaybar, and suspension mounts must be located in the exact same position and manner as on the original frame.

7.1 & 7.2 are not very spacific

7.1. Clutches – Must use a steel external clutch that meets OEM stock specifications.

7.2. Flywheel/Flexplate – Must use steel flywheel or flexplate that meets OEM stock specification. Must be bolted to and turn positive with the crankshaft.

no time to go over anymore now

i think the flywheel rule should be cleared up...

Thanks for the input guys, remember the revised rules allow us to run at several other tracks.

Gunner & Josh –

4.3 - I think the rule was ever changed last year because there was confusion about how the measurement was taken - height perpendicular to body or length of material(It was 5” above body)? I agree pick a number and just go with it. I don’t think the number matters as long as everyone uses the same size. When I ordered my body from Performance Bodies, the package came with your choice of 5” or 8”, so I ordered the 5” then had to hack it down to 4”. What a waste of time.

5.1 – Seems to be a racing rule standard. Does changing a spring mount 2” produce the same results in a leaf spring car as a coil car? Boy, could be a can of worms and that’s why the other tracks make the point. Just guessing.

7.1 & 7.2 – Maybe this is best explained with an example. OK, my car was built from a 1978 Camaro. I run a four speed and I need a new flywheel.
If the rule said;
“Flywheel/Flexplate – Must use steel flywheel or flexplate that meets OEM stock specification.” That means I can walk into a GM dealer or my local parts store and I can use any steel flywheel his computer says replaces the flywheel on a 1978 Camaro, 350 CID engine, 4 Speed.
Now if the rule says;
“Flywheel/Flexplate – Must use steel flywheel or flexplate that meets OEM specification.” In this case, I can use any steel flywheel that replaces any GM flywheel. From a Chevette to a Dump Truck!
Now if the rule says;
“Flywheel/Flexplate – Must use steel flywheel or flexplate.” In this case, any steel flywheel, produced by anyone for any manual transmission. If a magnet stick to it, it’s legal!
I don’t know what “Must be bolted to and turn positive with the crankshaft.” Is trying to eliminate. It’s in our 2009 rules. Are there flexplates/flywheels that aren’t attached to the crankshaft or turn the opposite way?

Now from a practical sense, when you go to NAPA, have them print out all the different part numbers that apply showing the flywheel is applicable.

Now it might be easier to just say, “ Must use a steel external clutch, minimum 9” in diameter, and 15 pounds minimum weight.” (Just picking numbers out of my hat.) Or something like that anywhere where OEM Stock specifications are required, but we’ll all need to check our components to come up with numbers that are reasonable.

Does that answer the question?
