I think I need new motor mounts for two reasons:
1) On the track a few weeks ago, when I launced my car I would get terrible wheel hop, enough to break my my center counsol and send one of the vents to the back seat. I was told that motor mounts would solve this problem.
2) secondaly and more importantly, my exhaust system is broken and the weld at the beginning of the resinator. Which I figure is because my motor is moving too much. I have a completely stock exhaust system from a 97 ls.

I almost 100% sure that they are the stock mounts. The motor has about 90k on it. I have already decided on my new exhaust setup, But I feel that i need to replace the mounts before hand otherwise I will just break my new exhaust system. Any other thoughts on this situation? Also, What kind of mounts do you recammend, or should I just buy inserts? If I remember correctely the rear motor mount, attached the the front crossmember, Is a solid piece of metal. So I should not have to replace that one. Am I wrong? Or does it have rubber in it also?

 

the rear motor bracket that bolts onto the block is a solid piece of metal, but it still mounts onto a rubber piece.

i'd check the rubber first to see any sign of wear and tear before investing. if that's the case, replace them then buy the motor mount inserts. i bought the Energy Suspension kit and it included three inserts: lower tranny, lower driver side, and the rear.

my car hopped like that also. i believe my hop was due to a poor suspension, which transferred to my motor mounts. even if you fix your motor mounts now, you might encounter the same problem again later. :thumbup:

 

How much does it cost to replace an engine mount?
My engine jerks a bit on every acceleration. It wasn't like that before.

 

How ever much the mount costs. DIY

 

Whe you say that you had a poor suspension set up are you refering to stock? Right now I am running eibach sportline springs, with tokico illumina adjustables. I messed with the shocks all night, and never really had a good launch though, then again I contribute most of my bad launces to inexperience with launching my lighted flywheel.

 

I bought the ES Motor Mount Inserts and they elminated all my wheel hop. I also replaced my front driver side mount it was shot.I recomend these thier 30-40 dollars so who cares
