POC classification question and confusion

[450knotOffice]

Guys, I'm trying to figure out the class my '84 Carrera will be in with the POC. I'm only planning to use it for STS events, nothing beyond that. I realize it needs a roll bar and I’m having one installed by TRE Motorsports in a month or two.

The problem I’m having is that I’m a it confused by the rule book as it pertains to classifying my car. I’m not sure if it would be JI or JP. Maybe you can tell ME.

Here’s what I have:

- 1984 Carrera (USA)
- Air Conditioning removed entirely
- DME re-chipped with a “performance” chip (i.e., re-mapped ignition and injection)
- Catalytic Converter removed
- Toolkit and Jack missing but spare wheel/tire still in place
- RS-style inside door panels
- Stock size wheels/tires with 140 treadwear rating DOT tires (non R-compound)
- Strut brace bolted in
- Torsion bars are larger than stock (stock is 19mm front/23mm rear – I have 22mm front/28mm rear size bars)
- Stock bushings
- Steering rack spacer to compensate for bump steer caused by slight lowering of car from stock height
- Turbo tie rods
- Weight is 2671 with full fuel (rollbar not yet installed. I imagine that would add 40 pounds or so)

That’s all there is. Can you figure out which class that car would be in? I’m pretty sure it’s either JI or JP, but I’m really not sure.

Thank you very much for your help.

JP at a minimum due to the t-bars. Improved only allows sway bar upgrade and r-compound tires.

You'll have some work to do...some quick cars in JP. I think top times with the bowl are around 1:30 and maybe a tad under. Practice good

Ha Ha, Todd!

Yea, unfortunately, I have what I have and this is just supposed to be for "fun" with my car anyway. I'll be playing with the back markers, I suppose, but that's OK. Like you said, practice, practice.

JP

And you are leaving a allowable mods on the table, so the car won't really be competitive. JP cars actually have a pretty high performance potential.

I just got a detailed response back from Martin Schacht of POC and he gave me a nice detailed breakdown.

Yes, I'm in JP class. He mentioned that I should definitely go with R-compound rubber since it's allowed in my class and de-cambered ball joints to allow up to 2.5 degrees negative camber (I only have about 1.8 degrees right now)

I have quite a few things which automatically drop me into prepared class - AC removed, a SW chip, and larger torsion bars. As you mentioned, Chuck, other mods are still on the table. I'll probably add them one by one over time.

Hey, I don't mind. It'll be a fun challenge.

JP can be a pretty competitive class and there are some well developed cars in it. Unless winning a little plaque every weekend is your main goal don't worry about it, the emphasis of the STS program is on developing better drivers. You have a good car to learn in.

Scott,
With the mods i've done to my car I'm in the IP class, so i guess you and i will be going at it together.

Whilst I have the POC Old Guard's attention here...
Where would my car classify...
I'm signed up for the Clinic on Saturday, and on the waiting list for Sunday- Funday! I left the class section blank on the registration, as I wasn't sure where my car would be classified

- '85 Carrera (USA)
- Air conditioning intact
- DME re-chipped with a “performance” chip (i.e., re-mapped ignition and injection)
- Catalytic Converter removed
- Toolkit, Jack, spare wheel/tire still in place.
- Larger than stock size wheel & tire combo.
8&9x16 Fuchs, 225/45&245/45/16 200 treadware tires(Non-R).
- No Catalytic Converter.
- Non stock exhaust - Headers & Dynomax Muffler.
- Stock torsion bars & bushings.
- After market adjustable front sway bar (Tarrett.)
-Turbo tie rods.
- Re programmed DME Chip.
- Weight unknown, as I've never weighed it... Might be a few pounds lighter with different exhaust.

Thanks!!!

Guys,

No worries on where your car is classified. There will be sooo many improvements that you can make as a driver, that having your car competitive is the least of your worries to begin with. I bought a prepared car that is in the V4 class. The first sts I went to, there was a new track record set on the streets @1:27 for V4 (in a car that I could've bought). It's laughable to think I could get close to that time in that car. You are going to have more fun than you've ever had in a car and although your times are important, they are important for improvement, not comptetiveness. Atleast not yet. I wouldn't even worry about changes to your car. You might find out down the road that you don't want to be in the same class anyway and go up or down. Now, for that 1:27!

Patrick, the headers are putting you in JP.

While Steven is very right that it is about developing the driver at this stage, it is also important to classify your car correctly. Else you my hose up someone who is a legitimate contender in your incorrectly-claimed class.

Further, you need to understand the classes and allowed mods so that as you develop the car you are moving towards your chosen class - and not creating a bastard that fits nowhere.

Yea, I hear you, Steven.

The biggest concern for me was simply trying to figure out which classification my car is in. That's all. I realize I am there to learn and have fun and I certainly know that my car won't really be even remotely competitive due to the fact that it's a cabriolet (more flexible). But hey, like I said, I just want to have fun and improve my driving skills.

I have a looooong way to go before I could be considered any good at all by the POC, but Patrick, Greg, and I all have quite a few informal track days with Open Track Racing and ACRA and I've already done one event with the POC, so I'm not a complete newbie at this. I've been on the track enough to know that I'm hooked!!

[PatrickB]

Thanks guys! Hope to meet you at the track?
I'm scraping my coins together to buy more of your fine products Chuck!!
I'll be talking with you more down the road about suspension mods I can do
to stay within JP Class...

I didn't mean to discount the importance of classification. It could definitely spoil someone's day or your own for that matter. After all, that's what this thread started out as right? Classification!

JP allows a fair amount of suspension mods. That is the main reason I moved from improved to prepared.

I have an 81 sc with webers and don't quite understand if that automatically puts me into a v class or if I'm in prepared. I have under 13pts. including the webers but the rules have me stumped. hope to meet you all at the sts event next weekend.

It seems I'm not the only one who thinks the POC's rulebook is a bit lacking in it's clarity. Confusing it is.

You're in a V class with webers.

The list of allowed mods in prepared is tightly defined, and webers are not in it. Your 13 prepared points must come from the "prepared" list of allowable mods. And they are use-it-or-lose-it, if you don't use them on the prepared list you can't use them on "V" mods.

carbs take a big hit, 10 points for non-stock manifolds, welcome to V class!
