Hi TwoDogs,
I expect that you must be rubbing against the suspension, when turning, if you are running 17"x8" with 35 offset on the front.
I have 17"x7" on the front with 32 offset, which sits flush with the guard and just clears the suspension, at a -1.0 degree camber.
Another important factor is how your wheels are aligned. I expect that with 8" fronts you must have the top of the wheels cambered-in so that they don't protrude beyond the guard. This will add to your problem, and wear the inside of your tyres much quicker.
I bought my 17" Work wheels new to get the 7"/8" stagger, and get as close as possible to the original offsets and alignment. To get 35 offset I would have to pay a lot more for custom offsets, but it would have been even closer to my suspension.
A wheel alignment may help, but dropping the fronts to 7" is better for steering. If you find that you are needing wheel alignments often, then you may need to replace some front wheel elements, like the ball-joints.
Your local Toyota Service Department should be able to photocopy the relevant page of the MR2 manual that provides the proper wheel alignment specifications. Generic wheel alignment business don't have the correct alignment settings, and you need to tell them what the correct settings are.
Hope this is of some help.
Cheers, M
