severe vibration after t5 swap

[manicmechanic007]

Damn straight, You never want poly mounts unless you are going racing and not worried about vibration
Used to run solid (steel) mounts in an old 69 Camaro. Could hardly drive the car on the street

I have urethane engine mounts, urethane transmission mount, and urethane transmission crossmember mounts and have little to no NVH in either of my cars. If it's done right i.e. balanced and aligned then you can run motor plates and drive it on the street and not have much vibration.

update on the new mount?
I installed my brand new transmission and it didnt change anything. Next step for me i think i want to buy a 3rd flywheel maybe more expensive and see if that does anything and if that dont help, i will try a oem bellhousing. Let me know if it helped with that oem rubber transmission mount

Now you are getting somewhere
Check the imbalance of your flywheel and crank to make sure they match before ordering another flywheel

Hey Dan
What brand flywheel did you use?
