i just wanted to know the benifits of having a stiffer Engine mount, these are ratings for Innovative mounts and im looking towards a 85A Race, car setup is Summer Only DD and from time to time weekends at the Track, thanks

60A Street (Red)
75A Track (Black)
85A Race (Grey)
95A Extreme (Red)

 

If you are looking to build your car the I would go with the 85A, but if you change your mind and keep it as DD, I would say 60A. The difference is vibration...from the stronger poly...So it's up to you if you don't mind it!

 

i just put some on my ls swap. i really love it the acceleration is really smoother and the shifts feel a lot better.
