Default Is pulling ABS fuse legal in Solo stock?

I did a search but could find only one reference of pulling the fuse in stock class but I was wondering if it was legal in SCCA. I am very familiar with the Solo rule book and the general statement that if it doesn't say you can do something then you can't. I also know that is not always true in actual practice. What I am asking is it accepted at divisionals and national tour events?

I don't believe it's legal. First of all, as you noticed, it doesn't say you can. Another indication is that the SP rules (14.6) explicitly allow it: "ABS braking systems may be disabled, but not removed". If it were legal in Stock, there wouldn't be a need for that rule in SP.

So I would say: No in Stock and STS/STX. Yes in SP/SM.

Thanks for pointing out the SP rule allowing it. I think your logic is correct. Tom H, did you pull your fuse regularly? Anyone else?

I tried it, but only in my Region. We didn't have STX, we had and Unlimited class that pretty much had no rules.

It's not worth it IMHO. Wnything more aggressive than the OEM pads would constantly lock everythign up even with a light touch.
Of course our asphalt didn't have as much grip as others.

Nope, its not legal to do it, and in autox I would not recommend it. I've done some testing and as long as you brake in a straight line youre supposed to, ABS doesnt become an issue unless you need it

I actually thinking runnning ABS in autox can give you a small advantage over not having it. I certainly have always felt more comfortable braking later knowing that the ABS will even out the braking.

This is a very old issue that comes back every so often. For some reason, some people think they can out-brake factory ABS systems and there comes that thing about disabling the system while racing.

Here are the facts. A very good driver can out-brake a decent ABS system in very controlled and planed environment.

Some of the ABS systems that where shoving up lately here in the States (like f-body systems and so...) where not that good while racing and just because of the low quality of those, people think that is the case with all the others.

While racing, there is no way that you can control everything that you need to do and still take a perfect care of your brakes. And if you are left foot braker (as most of people driving turbo charged cars should), than things get even more difficult. Now, if we add the rain to the whole equation...


Good luck and keep those systems running and work an your skills with that system ON!

Although, for anyone racing a slushbox in these sorts of competitions, the transmission automatically _upshifts_ when ABS engages! It's the only time that the current generation 4EAT will upshift beyond the setting of the shift selector.

Makes for very slow runs around hairpins.

I know when I had my ABS pulled I wasn't able to modulate effetively due to the way-to-squishy Subaru brake pedal. Although the feel was better I found I was constantly locking the brakes, to the point of turning my rotors after every couple of events. Not worth it.

I have to completely disagree with pulling the ABS fuse while autocrossing. If you look at the ABS system (factory service manuals) you notice that there are G sensors located around the car to determine the conditions of braking. In a straight line, I agree ABS will outperform a vast majority of drivers. While cornering, ABS in is these cars is nothing short of hazardous. Rather than being able to able the brakes in a controlled fashion as you start, progress, or exit a turn to compensate for extra speed, or off line issues, the ABS will completely eliminate what ever traction you had. Since most of auto-crossing is turning, I find the ABS gets in the way and does not allow for mid-turn corrections.

If you have to brake in the middle of corner, or even worse at the exit of one, you are doing things way wrong and no ABS system can fix that. The only correction for that one is that nut behind the wheel.

Do not expect that ABS will be able to correct your mistake of braking too late in the turn or to compensate for the bad tuning of your suspension. Unfortunately, lots of people would rather complain about the brakes or whatever else, instead of blaming themselves, but at least that is what makes us humans...unless you are Mark Dadio

Thats what I was going to say as well. Fedja just beat me to it

Our ABS works just fine. I havent had any issues with mine when I learned how to brake in a straght line and modulate the brake pedal.
