Stability control in some corners?

[shad0wca7]

Today I noticed something weird - I took a corner, not particularly fast or exciting and the stability control came on - I'd previously thought that it only came on during breaking?

Stock car? What wheel/tyre sizes and brands?

[shad0wca7]

Stock car, spacers on the wheels (20mm front, 25mm rear). Fronts are Falken ZE950 (225,45,18) (I think) rears are Eagle F1 Assymetric 3's (245/45/18)

From having a read of the manual... sounds like it's fairly expected if it thinks the road is slippery. Didn't seem to be (and it's nice sunshine today) but oh well.. Probably nothing to get too concerned about

Must be what saved my ass last week in on the Runcorn slip road onto the M56. Very tight bend, wet, back end flipped out, then it kind of just gripped and righted itself.

Cool.

Sometimes even at reasonable speeds the rear wheel can hit a bump/pothole and skip, therefore spinning a little quicker than the front, enabling the TCS to kick in. Another option is the rear tyre - front tyre tread depth, if the rears are near worn out and the fronts are new, this can unsettle it also.

Also mixed tyres

Rears are new and fronts are a little worn. it was a downhill turn and there seemed to be dust around so could just be something like that I guess!

I was leaving that one for you to say

It's useful for those unexpected scary moments. Keep mine on if very wet / motorway etc.

 

Mostly keep it turned off now; don't like trying to join a busy roundabout when a little slip occurs due to slightly dirty off line / tight junction / camber etc - a few degrees opposite lock and the rewarding sensation of a small slip angle rather than, oh I've had all my power cut and now I'm a sitting duck!

I would say this is definitely mixed tyres! My zed when i bought it had toyo proxies on the front and Eagle f1s on the back and used to come on all the time under all sorts of cornering. When i changed to MPSS all round i never had it again.

[shad0wca7]

Ah I see. Well I'll swap the fronts to F1s as soon as I can..

I believe its to do with the different grip levels front to back that makes the traction control think the car is going to spin when it isn't really. You could probably get away with mixing tyres if the grip levels are similar

Precisely, its just one end losing traction before the other .......... exactly the same as if you were running 4 tyres that were the same all round, if they were 4 Fullrun Nogrips it would be happening a lot sooner than with F1's on the back and Proxes on the front as well.

 

The TC doesnt do anything until a wheel starts slipping, and that is specific to the single wheel or tyre, not the combination of 4 tyres.
