Do any of you have stiffer polyurethane motor mount inserts, (ES, Prothane) and big cams that give a lumpy idle? I have a non-VTEC LS with Crower 403s and I want to get the inserts for a variety of reasons, but I also am trying to keep it a livable daily driver - the goal being that girls/parents/co-workers can ride in it and not be like "I can't wait to get out of this POS." I'm wondering if the stiffer mounts transmit a lot of the throbbing engine movement at idle to your seat, steering wheel, shifter, etc.

 

I have aftermarket mounts in my car- not sure whether they are polyurethane or not but it is very stiff. I can't imagine that you could have much worse of a ride then me. My supension is very stiff so I wouls say go for it

Are you talking about suspension bushings or motor mount inserts? My ride is fine, it's the engine vibrations I'm concerned about.

 

Both

 

the ride is fine unless you are shifting hard then you will feel the hard pulls of the motor i have polyurethane around my teg

 

i had the motor mount inserts in my prelude in they were fine. they didnt make it real rough or anything.

 

i had just the lower 2 inserts (ES) installed on my stock. I had vibration at idle, the dash would shake a bit, especially around the gauge cluster area.

I can only imagine what cams would do, and if i installed the rear mount insert also.

 

I have the poly mount inserts along with some 403's in a b20 and the cams lope like no tomorrow and the inserts really dont help. But to me its not a problem im used to my dash and steering wheel vibrating at idle for a while now and really dont mind it, its also daily driven. Better to have a motor staying in place then having it thrown around between shifts.

 

i have hasport motor mounts with BLox HSL's that are bigger than skunk2 stage 3's and mine is fine
