I have a '97 993 coupe that fits into D stock. Do any of the following modifications bump it up a class if I meet the weight minimum ?

Lower dash removed
RS wing with carbon fiber hood
A/C compressor removed
JRZ remote shocks

If something as simple as installing the a/c would keep me in D that is the plan. D stock weight is 3064 and I am right at 2900 depending on fuel. Add 175ish pounds? Drive in C as a RS which allows 2794.

Is this weight with minimum fuel?

thanks,

DCLee

Cuz:

The wing bumps you up to C-- specifically, the center vane.

The under-dash removal also sounds problematic.

And you're way under stock 993 weight.

The hood is a gray area-- I think tech inspectors have discretion to accept it because of the just-enacted rule change in GTC, which permits backdating using substitute materials when original parts are not widely available (for instance, a factory aluminum hood). I have extensive e-mail traffic form Tom Charlesworth, until recently the national tech guru, and he assured me it's gonna be OK. Plus Hank and a certain Dude I won't mention have gotten their cars classed in C as RS Clubsports with the composite material. It does not constitute a performance gain and is certainly in the spirit of the original RS car.

But overall... Welcome to C stock, ol' buddy. (No need to add 175 lbs. ballast-- just use the gravel you picked up at Summit Point last weekend

Lower dash removed
Only allowed to facilitate a rollcage installation, otherwise bumped to GT-1

RS wing with carbon fiber hood
Not allowed, bumped to GT-1

A/C compressor removed
Not allowed, bumped to GT-1

JRZ remote shocks
OK

Clarification: If the "wing" you refer to is the 993 RS spoiler you are OK in "D". If you are talking about the 993 RS Clubsport wing then you are bumped to "C". Carbon hood still bumps to GT-1.

Further clarification: The weight is when the race is over, period. Whatever you got when you are brought into the scales minus the driver. It's up to you to manage the fuel.

Hmmmmmmmmm, so I can easily put the lower dash back and hang the a/c compressor and drive C. The carbon fiber hood I will investigate further.

How about the rest of the interior missing like behind the seats is nothing but yellow metal. No seats, side panels...

Lee: That Summit Point gravel was part of a tire test. You did not think I lost control of my car did you?

Bill, I just had my car looked at by the Chief scrutineer at Sebring( I bought my car from him with the intent to race stock class).

1. You will need to replace ALL interior parts in order to stay in your class. The one exception is if, as someone mentioned before, removing items to install safety devices. For example, I can replace my door panels with RSA ones in order to fit in a NASCAR style cage.

2. AC compressor and all condensors must be in place but belts and hoses do not have to be hooked up.

3. The hood was not a factory option on you car if I'm not mistaken?? Then you will have to stick on the original.

4. I believe that the shocks themselves are not a problem but the inboard adjustability is. I will check with him if you want.

I hope this helps and I look forward to seeing you out there!! I will be at Limerock corner working this year and Club Racing there next year. I believe my friend will be scrutineering this event. Once again, feel free to ask me any questions and I will pass them on to Dave.

Cheers, James

James, The remotes for the rear shocks are inside the car. I could not put the back seats in without relocating them. Sounds like this is turning into a big deal to get the car stock legal. I would get killed in any GT class.

I should have investigated this before I modified the car. I was sure DE's would be my only track events.

I remember you saying that too Bill. Oh well, shouldn't be too hard to change a few things back. I think you can get an RS carpet piece to cover the whole back seat area simply.

Bill,
I thought we had this conversation last year!
Put the stock hood back on. Add carpet to the interior. If you want to run "D" stock remove the center wing (provided you haven't done any other mods that would put you in "C") and add the AC compressor.
Or as Lee said run as a RS Club Sport in C stock at 2800#.

Good luck,
Greg

Phil

excuse me for my complete ignorence here. What are the differnt specs for each class? Why would "not having carpet" affect which class? etc?.......seems to me, that some of these things are not that big of a deal? but then what do I know?

Greg Fishman

Phil,
I don't know why some of the things mentioned are not allowed or required but that is the way it is.
PCA wants the stock class cars to be very close to stock.

Greg, We did look at this last year but I decided to work on the driver instead of the car. Now I want to avoid showing up and having a issue. The C stock adding the carpet and a/c compressor is easy. Last year I also had all those little jobs that needed to be done like the cut off switch and seat brace.

I am looking forward to trying a Club Race. From what I hear it is as exciting as 10 DE's.

Here is a novel idea...

Check the rules book so you can see exactly what you can do to keep the car stock and what would put you into a prepared class. IF you go GT prepare to spend a lot of money to be competitive in GT2 (where a na 993 would be classed).

My last race was in an F class 911 that was fitted with factory spoilers, factory ROW sport suspension, RS door panels to facilitate the cage.

Your car can be bone stock, but as soon as you start to strip out the interior it bumps you into GT.

Have fun and stay safe.

Phil,

Check the link to the rules, it lays out in detail what mods are permitted, and there's a "500-Pound Gorilla" rule that says that all modifications not specifically enumerated are prohibited.

The spirit here is, if we're going to control costs, let's have a racing series that will allow you, with minimal modifications permitted, to show up in a street car and compete on the track- pretty closely tied in with the Porsche philosophy of building a sports car that you can drive off the showroom floor, bolt on some slicks and a roll cage and compete (as some guys did at Daytona in recent past).

Like everything else there's a significant amount of "creep" in the rules-- carbon bumpers and spoilers, super-stiff suspensions and tires that clear the fender lips by the thickness of a credit card (with the numbers worn off by excessive use getting there, naturally), racing seats and harnesses, fuel cells are all permitted in stock class, so that the COMPETITIVE cars are pretty significantly removed from what you would find in a showroom, but the scrutineers hold the line, e.g. every Carrera exported to the US came with Air Conditioning, so you have to have an a/c compressor.

There's an intermediate step called "prepared" that allows more aggressive modifications, which bump you up the classification ladder (move you with the faster cars). It's still "stock" but you are reclassed if you have certain modifications, e.g. converting to carburetors on a fuel injected car (except MFI).

Any modifications that are outside the scope of stock will immediately bump you into the appropriate "Super" or GT-n class, but the problem with that is, GT cars that are competitive have had EVERYTHING done, e.g. carbon bodywork, professionally built motors ($$,$$$), reworked suspension pickup points etc. so that if you're (Stock + 1 mod) it's like being a sheep in among the wolves.

Hope that clarifies things a bit. It's actually a pretty easy rulebook to understand compared to some other sanctioning bodies.
