I would guess not

Poly bushings are usually marketed towards the high performance driver. They have less give and your suspension and alignment does not "wander" as much in the twisties.

They are a little harsher due to the less "give" and will squeak in not lubed properly when installing.

I don't think they wear any faster. I had a set in my 914 Porsche for about 8-9 years & 30,000 miles. I sold the used bushings later when I chopped the car and they bushings had no noticable wear.

Not too many people racing the Benz
