I doubt putting a bunch of heat into the tops of the strut towers is going to help. The Minis are notorious for this and a bolt in pinch plate style is fine. Looking at the 1's towers, I doubt it will ever be a problem.
On a race car that is running 1000# springs, solid bushings and splined swaybars would cause more problems. But most cages should be tied in to the strut towers to absorb the loads.
On a street car and even occasional HPDE car I would be suprised
