I have a question. I ordered new motor mounts from Schumacher . Also ordered a new tranny mount from them. Will polyurethane be too stiff for aggressive shifting ? Should I go with a bit softer trans mount ? Or will having all my mounts polyurethane be ok. ?
I personally would do solid motor mnts and rubber trans mount. urethane should be fine on the tranny. im assuming this is more track than street? solid motor mnts will keep the engine from twisting. you don't want any deflection!
