Drivetrain Torque steer anyone? R56
Torque steer anyone? R56
I am highly curious as to what can be done to squash a vicious case of torque steer. I have the DSC which is disengaged (if I want to straight line accelerate) and the sport button on. The car is plenty fast, but I notice tremedous side to side torque steer. It pulls hard to the right then switches up to the left equally in distance about 6-8 meter intervals all the way to 4th. Is there ANYTHING to buy to limit this? I am curious to hear everyones ideas.
Many have reported that lowering springs help a ton, or the JCW suspension if you have money to spare. Both keep body roll and drastic weight transitions under control. Also a good set of non-RF performance tires should combat it to some amount.
Other than that, options are rather limited. It's pretty much 'the nature of the beast' when your dealing with a relatively high powered FWD vehicle. Hold on to the wheel tight and enjoy the ride!
Hmm, that said, maybe the JCW 'fatty' would be of assistance as well.

I have lsd (i leave dsc off) and I find that it pulls pretty straight, it fights you a little, but that its WAY easier to control with sport off, the steering isn't quite so hernia inducing. Its not that bad but it certainly wanders a little bit. I have hankook RS2s, they're really sticky, so it doesn't really happen anymore in a straight line.
Trust me....I have nothing but high-respect for the MCS, but as msteadman mentioned, the MCS is a different "beast" and power is one of the variables that could be dialed-down for perfectly capable MINI motoring. Naturally, some want more than that and so certain accomodations must be made as unsalada says.
Not intending to flame here at all...just trying to get at the issue by all realistic means available to the potential owner trying to configure the MINI they'll motor in every day.

Got to agree. I have the MCS and, personally wouldn't get an MC. But, it is that "S" that gets you the torque steer. If it bothers you that much, and you can't back off the quick-starts, an MC is a great solution.
anyone have get their mini with the sports package? any comment on any significant torque steering. i hate torque steering but have yet to purchase a mini myself. im planning on gettin the sports package which i think comes with a different suspension setting or suspension all together.

I rented a 06 cabriolet for 2 months non S and it was a terrific car. So terrific I didnt even drive the R56 Coop S before buying it. I definetly want to lower it seems like that might help, It sounds like I should get the front end "locked" up 100% power to each wheel.
Is there any after market steering componets that combat the torque steer?

Like unsalada, I've actually come to appreciate it to a certain extent.

Mine has been lowered with H&R springs on Sport Suspension. Runflats have been replaced with regular rubber.
DSC & sport button "ON"... LSD spec'd... and I get ZERO straight line torque steer. You can go WOT with the peddal to the floor and take your hands off the wheel. It does nothing but go straight and true.
Cornering and adding power is a different matter, though. You definately have to put some effort to keep the drive wheels pointed in the right direction.

This supports my theory that the wild ride under hard acceleration comes more from differential traction than true torque steer.
Nice to know that it can be tamed. Too bad Mini won't do it at the factory...

911,
I'm not sure how a lowering spring supports your theory on this one. I would think that the lower spring is stiffer and thus when you accelerate there is less weight transfer to the rear. When the front lifts, the angle of the suspension changes, thus my theory is less front lift equals less steer????
Are you thinking that the tires are actually losing grip?

Yes.
But, according to my theory at least, they lose and regain grip at different times which leads to the squirrelly pulling in both directions during hard acceleration. The LSD, stiffer springs and non-run-flat tires might be improving the traction just enough to avoid slippage given the available torque.
True torque steer would cause the car to veer in the same direction each time during hard acceleration and that's not what I've experienced.

LSD makes much more the torque steer when cornering. If I floor it on a corner, the car tries to tighten up and you have to force the steering wheel to get it to start to unwind from the corner. This is very repeatable but I don't understand it. I would have expected LSD to try to even up the rate of rotation of the wheels - making the inside wheel try to turn faster and the outside one slower. This should be straightening out the car, not tightening the corner. What is the physics that tightens the corner?
