James,
There are many Boxster forum posts describing spacer use from 5-18MM. There may be
one who said he had a problem with a wheel bearing. But, the bearings will fail anyway with mileage and there are several postings of this normal failure.
2MM clearance: I remember a description of a "credit card" thickness clearance by an established Boxster forum poster (on a different board).
We had a wheel rubbing on the damper; turned out to be a bent wheel and we ground it smooth to solve the rubbing. The wheel would only rub and very hard right hand turns on the track.
If you have a tire rubbing yhe tire would fail before the damper would have any problem with heat, IMHO of course.
James, when you get your project done put up a photo on the forum
Take care,
Ed
