ABS on the Track - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I had my 2000 Boxster S at the track on Saturday and under really hard braking it seems that the ABS would kick in. As this is my first track car with ABS, I never experienced that before. Is it normal? Also, is there some technique I'm missing that would prevent the ABS from taking over in these situations?

Thanks,

Art

1a) It is normal, especially in bumpy brake zones.

1b) You may try different ways of applying the brakes. I found ABS engaged much more often with a hard initial application than with a "soft" initial application.

2) Not sure what tires you are running but I noticed a SIGNIFICANT drop in ABS pulses when I switched from "street" tires to nice grippy "R" compound tires.

Interesting. I rarely engage the ABS on the track.

My approach is for threshold braking that takes me right up to the point that ABS would engage. This is probably carry over from learning in a 911 SC, without ABS. Smooth, yet hard, consistently applied pressure is the key. Understanding what it takes really comes with practice.

I'd be curious to know how many people that track car their cars, consistently brake to the point of ABS activiation.

I commonly use ABS at the track. Not every corner, mind you, but at the end of a long straight or where maximum braking is needed (instead of just a jab to set the car). It's not EVERY time I threshold brake, but it's not uncommon.

Yes. Occasionally I go into ABS at the track. I like to explore my breaking limits early in the day. Usually If I stab the brakes a little too hard or if I hit a patch of sand. ABS can be a good training tool, my own HAL9000 "Sorry Dave, you've just exceeded your traction limits."

A little smoother next time, no ABS, slow in, fast out, life is good.

I seem to, and try to, rarely get into the ABS on the track, unless its an oops situation. Last time I did, I'd picked up a lot of speed in the straight after exiting the entry corner perfectly, (well.. at least a lot better than previously) and didn't adjust my braking point. oops! LOL.. the instructor was also trying to apply the brakes, his right foot trying to put a hole in the floorboard. Darn.. missed the corner but kept all four on the track, barely. I think ABS is a great learning tool for where your threshhold braking point is, and where traction runs out. Topless is right... it tells you you're at the limit. Slow in, fast out..ain't it fun!
