Most likely that is normal because torque steer exists.
It's not heavily pronounced on the MINI, but it's definitely there.

It is normal to have some torque steer on FWD (and probably front-based AWD?) when you floor it (especially in lower gears). As long as the car doesn't pull to any of the sides under normal circumstances or minor acceleration, there's nothing to worry about

That depends on the FWD design. I had a Honda CRX (mk 2 VTEC) which had equal-length half-shafts so didn't suffer torque steer. Typical FWD has unequal shafts though (as the engine is usually mounted transversely with the gearbox on one end), so you have to just deal with it.

Yep, I know. Not saying all FWD have torque steer but that it’s normal to have torque steer on FWD. However, IIRC barely any fwd cars nowadays have no-torque steer suspension design. Megane RS maybe?
