Is there any mod out there that I could fab up to stiffen my stock mounts? 3 of them are off now (clutch change) so I figured id make them stiffer. Anybody? And no I dont want to invest into aftermarket mounts yet

 

Although I have never personally done this I've heard about people drilling holes in the rubber and injecting silicone specifically the silicone used to seal up a windshield to stiffen them up. Search around as apparently its an old DSMer trick.

 

press out the stock bushings and press in stiffer ones.
torque solutions sells these. dont know if u have the time to wait, but if u do.

 

Ralliart is rubber compound & stronger then oem, enough for high hp applications & with a slight increase in vibration inside. Don't get polyurethane that will be awful with the harsh vibration & effects the cv joints, etc!

 

I drilled holes in mine and filled with liquid urethane from McMaster Carr... they have held up pretty well for 2 years now...

 

Thanks for the input everyone
