If you have 7x13 wheels, then you might very well experience "torque steer" even with a 998, simply because they run a large KPI to contact patch offset, and the smaller sidewalls are a lot less tolerant of un-matching geometry (side to side) than a compliant tire like a 10".

Follow everything Steve says - Oh, and it is never due to the driveshaft length difference... It's always down to geometry.

Check the steering arm bolts are tight on both swivel hubs and their dowels are a good fit.. I've seen torque steer in Minis a few times when these come loose.

A Mini that has something close to standard power, let's say 100BHP or lower, won't show touque steer. The drive shafts aren't very different in length (about 20%), they are substantial in diameter for the amount of power(the same diameter as some 200+BHP cars). 

If the car is pulling on acceleration or deceleration the problem is likely to be in the suspension bearings/bushings, engine/subframe mounts, or the alignment.

Any thoughts if it could be a suspect upper engine stabalizer?

I don't think torque steer occurs on deceleration.

Suspension is great, new bushings, tie rods are good, new shocks.  All is set up properly. 

 

What would you not check? Out board steering rack ends, have someone hold the steering wheel and check free play 3 and 9 oclock around the wheel / tire. Ball joints again check free play 12 and 6 oclock. Lower control arm inner bushings take a close look with some light. Either they are in place and sound, coming apart or gone. Tie rods from outer lower arm to front corner of sub frame. Check both bushes at front and bolt at lower arm. Some times the off side rack bushing goes out and allows free play at the rack. I'd also check the toe should be about 1/16 to 1/8 out. If that isn't it we can talk about torque steer. Steve (CTR)

its totally normal the car to have some torque steer. This is caused from the unequal driveshafts length.

When I accelerate hard in my Mini and then let off the accelerator the car jumps left, any diagnostic thoughts?  It is a 1308, Hydrolastic car  converted to dry with newer suspension pieces.  I am going to look at it this weekend, was looking for a starting point.
