ABS when racing?........

Do you guys race using ABS or do you dissable/remove it?.....I do a fair amount of track days and when i does kick in it feels kinda strange.

Any advantages or disadvantages for not using it?......

Thanks in advance.

Most track guys disable it. The disadvantages of running ABS occur when you have an off. You've heard the expression "two feet in". Well, with ABS that whole concept gets screwed up. The tires don't lock and your out of control spin/crash gets unpredictable for the other cars behind you. The other disadvantage is when you're off in the mud/gravel trying to get it whoa'd up. With ABS, again the wheels don't lock which means you'll fly over the surface instead of digging in. I've seen lots of DE guys go into the barriers instead of stopping in the gravel because of this.

I think our ABS systems suck-ass. Everyone who has it should pull their ABS fuse. Especially for auto-x and track work. JMO of course.

i agree with everything said above...but i want to add something. no human can modulate a brake pedal with the same speed and efficency as an abs comp. so your stopping distances (normal braking line) may become longer than usual.

You haven't driven a B13 with ABS then.

Not only is it painfully slow, but it's just 2 channel instead of 4, so when your right front tire for example starts to slip, it cuts brake pressure to it, as well as the left rear.

The only good thing about B13 ABS is that it's easy to disable.

Well, you tell me. Have you driven this ABS equipped car?

You're not going to get anything positive about the ABS in a B13 from me. I had a 92 B13 with it years ago, and disabled it after experiencing how bad it was in the dry, in the wet and in the snow.

One thing to check though, I was going through this same conversation with another fellow on the forum a few months back. I think he was from the UK, and IIRC, they got a different system than the US, perhaps a 4 channel one.

LOL, yeah our ABS system is quite innefective really. To slow to really react properly. I disabled it on the street and for SURE would have it disabled on the track.

Yes for the past 4.5 yrs! It is 4 channel. It rarely comes on but when it does, like i say it`s a kinda funny sensation.

In that case, I reserve all comments. Your system is different.

I am absolutely positive I can outperform the ABS system on U.S. B13s. No problem at all. In all honesty, I think locked up squeeling tires stop more effectively than our ABS system.

All the kids remove it completely. I saved 15.8 pounds on the actuator and 3.2 on the bracket. The fasteners, computer, wire, and sensors are probably just North of 1 pound. I did not, however, weigh all the different brake lines from switching over to a non-ABS BMC and lines. Maybe another pound here to be conservative?

Based on Matt's comments, that's 21-23 pounds of pure crap that's easy to ditch. And cheap too! Bringbring!

Is there a simple way to know/check if my B13 has ABS? I've always assumed it didn't, but I've never really tried to figure it out for sure. Is just the fact that I don't think I do evidence enough that I don't?

There's a really big indicator light right in the middle of the instrument cluster that says "ANTILOCK".

My guess is you don't have ABS. Because it's such a horrible system you absolutely would not forget what it feels like when it engages.

After reading the seething hatred for the ABS system on the B13's, I'm almost afraid to ask this, but has anybody ever tried retrofitting a functional 4-channel ABS system into a B13? I hate my ABS system on my B13 6 months out of the year, but I will say that with my high performance all-season tires, it has saved my ass a couple of times in the snow piles I have to deal with in MI.
