Slammed Spec mounts raise the engine by 10mm giving you more oil pan clearance. Scrape Spec mounts raise the engine by a full 20mm. They are considered an extreme upgrade and both require supporting mods when installing.
* E36/Z3 Fitment Notes for all riser mounts:
- The fan shroud will need to be modified slightly to make clearance for the fan position moving up.
- May need to trim the lower radiator hose .5" to clear the AC belt.
- The Vanos cover could make contact with the hood on 98 328is.
* E46/Z4 Fitment Notes for all riser mounts:
- The engine hook on top of the motor needs to be removed
- The fan will need to be raised by 1 inch.
We highly recommend installing the transmission and engine mounts as a complete kit. Install all Non-OEM height mounts at your own risk.
