Hi there,
The motor mounts are custom made for our cars. We have stock replacement units in stock .If you are looking to upgrade from the stock units we have a solid mounting which we run in all of our track cars. I am not aware of any other options used by customers. If you are looking to try the solid mounts give Craig a call on 561-752 3693 and we will get a set made for you.
