Vorshlag designs and builds a line of modular, bolt-thru, competition style motor and transmission mounts for various BMW chassis with BMW motors, which we introduced back in 2006. These are meant to replace the soft rubber and/or hydraulic filled “luxury” driveline mounts that the factory uses in these sports/luxury cars. We designed these to be compliant with various SCCA class rules that stipulated a “maximum metal content”, but the rules changed in 2013 so we change our design to reflect the rles update.
More metal was added to the CNC machined aluminum base, which better supports the bushing insert (polyurethane or Nylon) on the E36/46/92 M3 version. You can see the added metal int he ghosted picture of the assembly, above. The assembled polyurethane E36/46/92 mount is shown below.
As always, you can read much more about this product and the 2013 update at this Product Announcement Post on the Vorshlag Forum.
