The car had RS engine mounts which is good but I wanted to replace them with Wevo semi-solid engine mounts which offer even better accuracy than the RS mounts. When needed the pillows can be replaced and replacement kits are available for example from twinsparkracing.com
The two bolts on each of the Wevo mounts shall be torqued at a maximum of 23nm to the car. The centre bolt on each engine mount can be torqued at a maximum of 54nm.
I also wanted to upgrade the transmission and engine mount and bought an insert kit from Tarett Engineering (tarett.com). Firstly, I removed the undercover and then the crossmember. Then the gearbox bracket could easily be unbolted to get access to the transmission mount. Did some proper cleaning before reassembly. Polished the gearbox bracket with my Dremel and then applied Jet Laq (raceglaze.co.uk). The crossmember was cleaned using Alubright Deoxidiser (also available from raceglaze) and scrubbed with wire wool and then finally Jet Laq was applied.
After having fitted the insert kit the gearbox bracket was torqued to 46nm and the crossmember to 85nm.
