ABS cut-off switch

[Porker]

I'm struggling with the ABS on my CSL, it triggers too easily on road and track. On bad roads the stiff suspension tends to trigger ABS, on the Nordschleife after Pflanzgarten the ABS is also triggered, with obvious hair-raising consequences.

Has anyone else installed a cut-off switch? Who to recommend?

Thanks in advance!

'ABS'? Do you not mean DSC?

ABS should not be triggered except in the obvious situations.

DSC will however be a big pain in the ass if you leave it engaged on track. Even in M-Track mode it will occasionally trigger unless you drive super smoothly.

What tyres, suspension, brakes and pads do you have, as I consider myself a very late braker and have never yet managed to trigger the ABS on the CSL (APs, RS29s, H&R coilovers and Cups)?

Also, with Planzgarten it is absolutely crucial to do all your braking before the drop or after the drop. If you brake during the drop, as the car unloads and reloads the suspension, it will indeed cause issues with ANY braking system and you could quite easily end up crashing by braking this way.....

I tend to brake come off the brakes, go over the drop and then when the suspension is reloaded again, give another stab if the car hasn't scrubbed off sufficient speed.

I think the OP means DSC.

.....as I consider myself a very late braker .

I was like that until I was taught better :thumbs:

GAS - YEs
DSC - OFF
ABS - GOOD
Brakes - Only if you have to

I use the handbrake.
No issues with ABS being activated :-D

I'd be looking at the suspension.

Agree

Or tyre pressures/grip,

I'd be looking at the suspension.

True enough, or geo, too much camber for example.

[Porker]

I do mean ABS, not DSC. On rough roads, it cuts in even under relatively soft breaking. On smooth roads or tracks there is no issue (except for Pflanzgarten).

I do run -3deg front camber, suspension is Intrax 1K2, brakes AP-racing 6pots with Pagid RS29.

Id say you have a problem, never had any ABS issues and have same set up as you. Cant recall last tme i felt ABS cut in

[Porker]

Although I should probably mention, by rough roads, I mean Belgian roads, that might clarify a thing or two...

What spring rates and damper settings are you running?

By turning off ABS you'll just lock the wheels so I can't see that improving things.

Unless there is indeed something wrong with my ABS sensor which makes it trigger too easily.

Don't know my spring rates, they were made specifically for Nordschleife-use, so I'd reckon not too stiff. Dampers are in their half way setting.

you might have really hard springs which would make this happen more htan normal (something like 140F/70R)
