G stock Question

[Chin]

Can you reduce the weight IE taking out the interior, but then just add the weight back onto the car where you want to?

[Slash]

i would have to say no.. thats hardly stock..


However I dont have the manual for it

i'm doing the same thing: trying to figure out what i can do and still remain in the stock class. i don't want to be STS at the fairgrounds this year. i'll get beaten by everyone.

per SCCA handbook:

"13.2 Bodywork

Accessories, gauges, indicators, lights and other appearance, comfort and convenience modifications which have no effect on performance and/or handling and do not materially reduce the weight of the car are permitted. This does not allow driver's seat substitutions or the removal of "tow hooks", a.k.a. "tie down loops". Delayed shutdown devices such as the "Turbo Timer", which perform no function while the car is in motion, are permitted......"

So, basically, no you can't gut out the interior. Whether they enforce that or not at a local level is questionable, but if you ever go to regional's, expect them to care.

[b16aRacer]

Also, whether or not you could gut the interior and then add-in "ballast", im not sure. Two reasons against doing it:

1. You'll have all the disadvantages of a gutted interior (loudness, appearance, etc.) and still weigh the same

2. Since they dont have scales at local events for your car, how would SCCA officials know whether you added in any ballast, and if so, how much? They're going to see the gutted interior and bump you out of G Stock.


I've been mulling over competing in G Stock for a while, and came to this conclusion: Unless youre a REALLY good autocrosser, you are going to get kicked all over the place. Stock really means stock, and besides tires, youre pretty much limited to what the factory gives you.


BTW- What car are you considering running in G Stock? Not a swapped 240SX, I would assume . I dont think they'd look the other way on a motor swap.

[Chin]

no, a 240sx coupe, whats the next level up?

most of your answers can be found here:

Hierarchy goes:

Stock>Street Touring> Street Mod> Street Prepared, then Prepared and Modified I believe?

Someone correct me if im wrong

[Loren]

The short answer "NO". They call it "stock" for a reason, silly! You can replace certain "wear items" like brake pads, tires, wheels (with the same dimensions), shocks, air filters and spark plugs... but removing stuff? Bolting in ballast? That's not stock.

My advice: "First tune the driver, then tune the car."

Unless there's something inherently wrong with your car, don't "fix" it. Just drive it. When you're driving it to its full potential, THEN it's time to either find another car or make mods to the one you have.

also front swaybar is open in STOCK class....

BIG help for most RWD cars, and a lot of FWD cars, although the ricer idiots will tell you otherwise...

[neurovish]

how about lsd?
stock class allows for 'trim upgrades', but what about 1/2 trim upgrades?
I have a 240 vlsd in my car, but not the anti-lock brakes and whatever else came with it...I would assume nobody would really care but would like to be sure so I'll have a reply ready if I get called on it.

RE: LSD (wow it's been years) :smirk:

Was it available from the factory with an LSD for that year AND trim level? If so, it's legal - the car can be configured to how it "could have" been ordered from the factory. If not, or if it's an aftermarket unit, than no.

[Chin]

hahah yeah LSD, and also a rollcage is allowed

[mofugga]

i have some sticky rear tires for you if you're interested!

[Matt Vassallo]

the limited slip differential is an option on a 1995-1998 240sx, but its 'package' includes abs. but putting abs into a non abs 240 is like a 3-4 thousand dollar ordeal.. the diff is a 300-400 dollar ordeal.

[Matt Vassallo]

you could, theroetically, take all of the cars interior

stick it into a grinder or shredder or wood chipper

bag it up and compress it, and move its weight around in the car, right ? :lol:

its still in the damn car, right?

[Loren]

Unfortunately, SCCA rules care not about the expense of your modifications. And the one thing to remember above all is "if it doesn't say you can, you can't".

In the case of the 240's in question, if the LSD and ABS were not available as separate options, you can't run in STOCK class with one and not the other. Will anyone care if you run a Regional event that way? Probably not... unless you start winning.

There is more flexibility in some of the other SCCA classes. If you move up to Street Prepared (or Street Touring), you can take advantage of what they call the "update/backdate" rule. That's the one that lets you do what you're talking about. You can take the best factory parts from cars of the same model range (the rule book defines them) and create your very own "option package". LSD from one year, trans with better gear ratios from another, engine from another (they don't allow you to break into the engine to swap parts), lighter radiator, bumpers and whatever from another year. You name it, it's been done.

But you don't get to grind up your interior and redistribute the weight until you get up into Prepared and Modified classes. :)

If you're gonna get serious about SCCA competition, you really should buy a rule book.

[Matt Vassallo]

hey i was just taking a shot at it. i know in road racing a few friends were doing that

[Leonard]

Prepared... interior??? What's that? You mean aluminum floor panels, right? :-D

Yep... and you can distribute those aluminum panels in any way you see fit. :cool:

Do SCCA rules also include cars from Canada?
Canadian 240s had the lsd without the abs.
Splitting hairs really, I'm not gonna start taking GS anytime soon

[PseudoRealityX]

technically, no, not allowed. nobody will care around here. Or even at national events until you start winning...
