2009 Rule change suggestions
 (United States) Modified By Travis  on 7/23/2008 10:21:28 AM)

 

 

Hope this works. Provide rule proposal and argument for it

1. Brake ducts allowed to be run from openings in front bumper created by removal of turn signals.  (modify : "Removal of the side turn signal assembles is permitted with the provision that any ensuing holes be covered." adding or holes are used as entry for brake duct hose. IF holes are not used for brake ducts, they MUST be covered")  modify: Backing plates and dirt shields may be ventilated or removed.  Air ducts (maximum 3" diameter) may be fitted to the brakes, provided that they extend in a forward direction only.  2 ventilation holes may be cut into the lower valance for the purpose of cooling the brakes adding or holes that front turn signals occupied may be used for cooling brakes.  Each hole is not to exceed 33 sq inches in area (including the stock brake duct ventilation on later cars.)  No material may be added forward or below the air dam.  Brake rotors and drums shall not be modified other than for truing within manufacturer's specifications.   - zero competitive advantage by using exsiting holes in bumper.

2. Remove door glass. - I dont see this in rules, so it must be in GCR per SS rules.  - SAFETY, zero cost to remove, lightens car

Not sure about SS but in IT, I think the door bars have to extend into the door in order to remove the glass.

Are the SRX7 rules supplementary to the IT rules? If you want to stay within IT rules check out 9.1.3.D.9 about items to be removed http://www.scca.com/documents/Club%20Rules/ImprovedTouring.pdf. Door glass is not listed as an item that can be removed and the only way it is done legally is "to provide for the installation of required safety equipment" as noted in the previous post.

IT rules on brake ducts...

Where an air dam/spoiler is used, two total openings may
be cut in the front valance to allow the passage of up to a
three (3) inch diameter duct leading to each front brake/rotor
assembly.


Where no air dam/spoiler is used, two total openings of a
maximum size five (5) inches by seven (7) inches maybe cut
in the front valance so that brake ducts can be added with a
three (3) inch diameter hose leading to each front brake/rotor
assembly.

Our rules supercede the SS/IT rules (though our Spec Book is SS) -- where the SS rules come in is where we don't have any specs listed. i.e. our rules are an addendum to the SS rulebook as they relate specifically to our cars; keeps our rules from being 50 pages long.

That is my only concern with removing windows and mechanisms is that then the cars no longer fall legally into IT, and with the incredible lack of cars at SCCA events, the ability to run them in ITA is a legitimate concern in the short-term, I think.

Travis,

 

 You'll hate me for this but...

 brake ducts where they are are fine, Yours just suck, that why your'e breaking rotors :))))))

As for the window glass, I don't think we should remove them, yes it would be nice to lighten the cars but it would restrict our compliance to IT. also I like closing the car up when it rains.

Donato, you wouldn't *have* to remove the glass.

Just like we don't *have* to remove passenger seats. ;)

Actually I guess I don't have a problem with the turn signal hole being used for air ducts.

I did that the first time I ran Spec7 until Tom Thrash told me I had to remove them.

I thought it was a good idea then and still do. I guess the only problem we had with that was people could'nt drive their road cars to the track race them and drive them home.....LOL!!!!!

Ohh remember those days when all rule changes centered around the drive to track and race philosophy. I actually remember a few that did it.  Have to wear your helmet down 6 because of the roll cage. :)

It's me again, hard  A$$ Mike. I agree with Donato about the brakes ducts. One thing I see in Spec7 is that not evryone understands the car and how things works. If you are having brake fade don't assume it is excess heat ( rotors are a different story).  If your problem is brake fade or a long pedal, you can easily test your brakes without starting the car. Just press your brake pedal hard, feel the pressure and if the pedal takes a inital set them fades, you have blow-by in your master. Replace it. Ask Rob and Bill S., they experienced this. Another thing about brake fluid, it needs to be changed. No matter the DOT rating it absorbs moisture from the air and  becomes comtainated (easier to boil the brake fluid/ brake fade). Purge all old fluid at least a couple of time a season.  Start at the right rear, left rear, right front and last the left front.  Run at least a quart thru the lines, it is cheap. I may not be the brightess racer but I did work for Skip Barber for 5+ years and learned a little.

Also, for the beginners. Go on ebay and purchase the books by Carroll Smith ... "Prepare to Race". It will tell you about the way different  componates of a car should work (steering, suspension, brakes). It was a racers bible when written ( and still valid) but sadly nobody bothers with them anymore, so they are cheap.

Another FYI, this time on rotors to prevent cracking. After a run when the rotors are hot, never sit with your foot on the brake pedal (paddock, tech, wherever)( aka Donato, use chokes to keep your car from rolling). This will trap heat in the rotor where it contacts the pad while the rest of the rotor cools naturally. This is the big cause of cracks. Think about it, it never happen on the track. The result is a stress crack caused by uneven cooling of the rotor.  Remember that a cool down lap is not just for the driver. Avoid standing water. Rotors do wear down and the tollarances are less than you think. If you see a groove cut into the rotor it is already past street car specs and probably should not be raced. Hawks pads are far more abrasive than stock so beware. That is unless you are a Tony or Donate who know when to brake and when to just let the car roll.

Thre old Skippy World sayings. "If you spin, both feet in. If in doubt, both feet out".  "Don't over rev" and lastly "Take you foot off the damn brake". Time for another beer and bed, I had a start to the day.

Re: 2009 Rule change suggestions

we didn't vote on anything in 2009..and I have heard some rule proposal ideas from some racers.. so this will be for 2010. .  For sake of making this a simple process. I believe we have to get the change proposal to SCCA by the June meeting? Chris you can confirm this.. Lets open up rule changes until January 31 2010.  Then voting will open up February 15th and close February 22nd. I will compile a list of rule proposal changes

You need to include the re-write for the rule book.

my two I posted earlier I still propose

1. brake duct placement

2. remove door glass

It's in July, but yes -- the only meeting they'll allow us to present rules changes at is the one that's in the middle of the damn season.

I'm all for removing door glass, what about the window tracks? Buncha weight there for the hefty guys (I still don't know how Mark is 200 pounds over weight). Plus then our LeMons car is Spec7 legal through and through! Okay I have to swap intakes because the LeMons car has water pump studs in place of the carb studs and 4 of the deck spacers.... but it's one step closer! Hey that's all bolt on stuff...... R&R carb studs with water pump studs, up to 4 total manifold spacers and a hole in the hood no bigger than 2" greater than the air cleaner diameter! AND it gives us more torque/power!!!!!!!!!!!!!!!!

In order to run STU the cars must remain IT "legal."

What rules? We are PTF. That's what a NASA official told us years ago.
