Hi ben, will be doing a couple of races in the superlight. Want to keep my license up to date and have it upgraded too.

Sure I will be seeing you about.

Just not got the time to do another full series.

average drivers in quick cars, you know who you are Mr M3 CSL owner




Surely the drivers of these cars are quick because their cars are quick? MPSCs let you get away with murder!!

What about when they are on normal road tyres?

That's just exactly what I was saying. I'm sure BMW spent lots of time at the Ring tuning the stability control - we don't owners doing it too, we need owners learning how NOT to trigger it and still go quick!

MPSC is a tyre, not a stability program

Hello, this has prompted my first post.

The stability program on the CSL doesn't actually make you lap faster - in fact it gets in the way and murders your exit speed (even in track mode) and messes up a properly commited entry as it's yaw sensors panic. Particularly if you are use to trailbraking into a corner to generate some yaw to quash understeer and then expect to get on the power and balance the chassis through mid-corner and exit. In those situations it refuses to give you power, letting the nose run wider and wider until the yaw has stopped - very irritating. You almost have to drive even neater and smoother with it on then off - at least with it off you get some rampaging wheelspin and a bit of a skid - but can maintain momentum. The stabilty stuff just steals that whole range of options away.

It works well in getting a driver out of trouble, but it does not in anyway assist cornering speed like AYC on an Evo.

Thanks Tony...interesting. Do you know if the TC/Stability on the CSL is different to the stock M3, 'cause it was killing me around Rockingham corners in a stock M3.

I think it may be in the different modes it has - but Nathan can answer this better I'm sure - it was his poor car I was ragging around. I just got in and pressed circle, square, held down ctrl+alt+delete and typed in 'BMWs rock' on the keyboard. Then I got 1000 extra credits to spend on upgrades.
(These electronics do my head in) Press pedal - go. That'll do me.

Was fun chasing a 996 turbo (running on P zeros). Even more fun was the drivers suprised eyes when he eventually let me past (on two different sessions). Didn't mentioned the fact that the CSL was still on normal road tyres, not cups. Nice fella though, good smooth drive - great to see the traction on that thing and he wasn't upset at us getting past him. Had a nice chat before his brakes caught fire in the paddock.

Also did some skidding. Which has to be the best bit about Bedford's layout!

Tony

PS: Rockingham is usualy a very dusty ciruit and that will trigger any stability control sooner, so I'd imagine you'd have to be even more gentle in how you tip the car into a corner and even more smooth and controlled with the throttle to stop it triggering. If you are going to that much effort you might as well turn the damn stuff off anyway.

The CSL has ABS designed for cup tyres and m-track mode on the dsc which is much, much more leniant than dsc but once it cuts in stays in for too long. The standard DSC strangles the car and cuts the throttle before the car is moving about, never mind once it is moving.

Tony - the turbo was on p zero corsa motorsports:

Of course there is the other view that says I've paid my £200 or whatever therefore, I'll drive my car however the I please within the rules laid down by xyz track day company. If I break the rules report me otherwise stfu.

wee_skids - interesting post. Sounds like the DSC on mine then - converts everything into speed-scrubbing understeer. As you say, good for predictability and protecting you from your own mistakes, but bad for lap times.

Realised after I'd posted that we were talking about tyres, but ho hum

So you CAN drive round by just chucking it in on the wrong line, waiting for it to slow down enough to get back into shape, and then booting it out, but that's not my idea of fun!

Yup, but the rules at MSV for instance are "be considerate of other drivers" and "no excessive and prolonged tyre squeal". So no hooning.

Fortunately the instructors generally take a sensible view of what "excessive" means...

How is one supposed to set up proper 4-wheel drift exits without prolonged tyre squeal, that's what I want to know!

Same difference though isn't it. If I break the circuit rules the marshals will have words with me and if I continue to do it they'll send me home. I expect their main issue with prolonged tyre squeal has more to do with local noise issues than it does with anything else. That said, I've driven all of MSV's circuits several times this year and neither the TDO or the circuit marshal have never briefed against excessive prolonged tyre squeal, whatever that might mean as you say.
