Just because an engine that is also bolted to a suspension subframe via a bushing doesn't make that bushing a suspension bushing.
But the GCR doesn't say only suspension bushings are free. It says "Bushing material, INCLUDING that used to mount a suspension subframe to the chassis, is unrestricted." While itincludes suspension subframe bushings in saying they are unrestricted it doesn't limit those bushing that can be modified to only suspension bushings in any way. It simply says bushing material is unrestricted. The intention may have been to limit changes to only suspension bushings, but the wording doesn't reflect that. Moreover the front subframe on many cars IS the front suspension subframe. If that's the case, any bushings on it are free by that wording.

"Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall, torque is how far you take the wall with you."
