Track Day - ABS and Tractions control lights
Brought the RX8 out on track recently for the first time. All went pretty well except that after a while the ABS and traction control lights came on and stayed on until I let the car cool down.
I'm guessing the ABS light could be caused by overheating brake fluid (hasn't been changed in the 1.5 yrs I have the car so gonna change that soon), but could this also cause the traction control light to stay on? It's been fine since so I immagine it was something overheating, but just curious as to what exactly. |

The brakes are very good, and I don't think I've ever set the light off by the heat or even if its possible. The DSC on the 8 doesn't interfer with your driving unless tires are slipping, but likes all 4 tires to be same brand and size (which also means close to same wear as a worn tire can be up to 2% smaller). I tried to run with new 225/40r18 in front and worn 225/45r18 in back which is about 1.5% smaller on the 40 series. On the street everything was fine, but on the track the DSC even caused me to spin at 30mph so I turned it off that day, and hung the tail out. :eek: Also, my 07 GT 6spd AUTO was even slipping the rears when turning and setting off the DSC, so I aligned to straighten up the rear excess neg camber from -2.1 to the minimum I could get on both sides: -1.65 and slight toe in with me in the car. Now, I can't lose traction under acceleration (unless wet); only braking or cornering, and the lights only come on if I've really gotten careless. |
I've the same brand (and wear) tyres all round, so it wouldn't be that. It was a wet day though and the track was very slippery, so both the DSC and ABS were being engaged a lot. Maybe it just reached a point where it had enough so the lights just stayed on until they were reset?

dont track with DSC on, you will get problems like this...
In all years I have tracked my rex i have had it off, except for heavy rain and I havent hade any of these problems. DSC on rx-8 are quite crappy and shall always be OFF. otherwise you cook your brakes and throw of PCM errors. |
Thanks for that. Will keep it in mind next time.
