Bought a 2020 Mini Cooper SE a few weeks back, and while it's great the torque steer is crazy. Any suggestions on how to reduce it, or do I have to live with it?

The only fast-ish front wheel drive cars I've had have been N/A and low on torque so I've not really encountered this problem before. Having said that, it's not actually got much more torque than the R53 Cooper S I had 10 years ago...

Would wider wheels and tyres help mask the problem? Upgraded dampers and/or springs?

Wider wheels would make it worse I think. More grip = more torque steer.

I used to find that when I fitted new front tyres to my Clio 172 the steering would feel much cleaner with far less tramlining and torque steer. I believe this was the increased tread depth meaning there was (in the dry at least) less grip.

It could be that worn suspension components aren't helping matters either, but I'm no expert.

torque steer is affected by unequal driveshaft length isn't it?

I'd look at suspension alignment and tyre choice to see if you can mitigate some of it out, or accelerate less harshly smile

Suspension alignment is a good shout, will get it checked.

I was kind of hoping that wider wheels and upgraded suspension would be the answer, since I'd quite like to get new wheels and some nice coilovers! Disappointing.

It's 6 years and 40k miles, so you'd expect suspension components to still be good, but I have had BMW's with dampers fail earlier than that so it's very possible.

Tyres are Hankooks. Never had them before, I usually go more premium. Tempted to change them but they're fairly recent and they're supposed to be a decent brand... don't want to waste money.

Accelerating less harshly is not an option, sorry. On that note, sport mode in the Mini is the stupidest thing I've ever encountered in a car - it's pretty much full power or no power, on or off. Who on earth wants that? Playstation mode, I suppose.

Has it got the standard wheels and tyres, and no aftermarket wheel spacers? Some torque steer is pretty much unavoidable on nippy cars without PAS, but there are mods that will make it much worse.

Yeah original wheels and the Hankooks are same spec as when new. Haven't specifically checked for spacers, but I'm 99.9% sure it doesn't have them fitted.

Pretty sure a 2020 Mini has power assisted steering?

I wouldn't know either way, but if it has I'd have thought that would suppress a lot of the torque steer.

When I had an R53 I was told by someone better experienced than I that the longer drive shaft had exactly the same "moveable" half as the other to dial out the torque steer.

I don't know if this is true or not but I took mine up to 235bhp & certainly never experienced any significant torque steer.

ETA.
Even with wider & stickier track day tyres there wasn't any.

It does have PAS.

They put hankooks on the top of the range audis AFAIK, RS5's etc so they are a decent brand, does depend what version of the tyre you have though.

When I had my GTR it came with factory dunlops and tramlined like a bar steward, switching to Michelins cured that.
