Our solid mount kit is ideal for track, race, and extreme
performance street vehicles. Does not harm ride quality but may add
a bit of noise.
By mounting the differentual using solid mounts, you can
eliminate the damage causing torquing and twisting between the diff
and subframe, as such, the VAC Aluminum Differential Mount Kit is
designed to unitize the differential housing and the subframe on
the E9X M3.
The result: improved driver feel and feedback, enhanced
reliability, and elimination of sub-frame tearing and chassis
damage that can occur when these mounts fail during hard track
VAC Tech Tip:
We have already seen damage occur from this failure using street
tires. If you drive your E9X M3 on the track, we can recommend this
is currently empty
