You can probably use the same front bar for the STX build.

there are no height changes in stock class. And one could easily take out 100lb from the rear via exhaust, fuel, and spare+tools, and without any ability to adjust for the increased rake and height.

This is all about playing around within strict rule set

and as was pointed out, even if I was to implement some of this, it wouldn't be legal per rules.

Your theory of adding weight falls flat because it is not inclusive of situations like slaloms. Predictability is what you want, and there's no reason to add weight to achieve it. If your car is loose, you can even play with toe settings in the rear to make it easier to drive.

Again, rear, does not mean on my bumper. Rear means before the rear axles and as close to the ground as possible. In fact I'd say that I wish the spare tire sat further inboard. I am fully aware of the effects of adding weight aft and above of the rear axle, any sort of weight THERE is without argument detrimental to performance for exactly the reasons you're stating. But I'm not suggesting wrapping a bag of cement to the top of my trunk lid, am I?


as an aside, a few friends on another forum jokes that maybe I should just pour cement into my gas tank

The closest thing you can do to what you're stating is to put the rear seat back down flat, as it'll shift the weight down some, but still a bit more forward than where you would want it. What you're trying to create, more or less is the effect of a mid-engined car I suppose, but I still think it would be detrimental under most conditions when compared to a car without the weight. Like I said, in a sustained corner that you ease into it'll probably do as you describe and handle better, but in autocross there's too much weight transfer. More weight means that when that weight transfers and you go past the limit of grip, it'll snap a bit harder than the car without the weight, making it more difficult to reel back in. It's more worthwhile, and fun (subjectively), to learn to drive a car to it's potential than to lower the bar because you run out of ability. There's always room for improvement. Get a good coach, not ballast. :P

I'd say just try it and experiment. You aren't causing harm to any of us by adding ballast in a stock class car... unless you start winning because of it.

In that case we'll protest

[bslate3]

Crazy question. Can I debadge the trunk, take off the Subaru and BRZ, and still be CS legal? Or will I get protested for removing half a pound off the trunk?

[14stu]

I believe 13.2A allows for removing the badges as "accessories".

[VADERR]

I thought it was only allowed in street touring since the rules specifically mention it :-/ 14.2 c

[14stu]

"Appearance and comfort modifications which do not effect performance or handling and do not materially reduce weight are permitted".

That's 13.2A, and I would consider the badges to fall under appearance items (I'm assuming they weigh about a pound, but we could always wait to protest later in the season if the points are close )

[VADERR]

Haha good point lol go ahead Brandon!!
