I'm ready for shocks too. I changed my worn out base shocks at 18k and now have 4k on some z-51 shocks and they are not very good,

Suspension Bushings?
I am installing a set of Bilstein Sport shocks on my C6 in hopes of mitigating wheelhop somewhat, and I was wondering what your thoughts are on doing polyurethane suspension bushings at the same time? LG and PFADT both make a nice set that would roughtly double the cost of my shock install, but I wonder if this is worth it at this time:
Being Polyurethane, they will make more noise, such as creeps and squeaks, particularly when it is cold, right?
The install is pretty involved since I have no hydraulic press; I'd have to torch or drill out the old ones...
And is there really enough compliance from the factory bushings that I would feel a difference, particularly in wheelhop?
I.E. is it worth $400 when I am only looking at spending $300 in shocks?

Been there done that with a previous car and I'm not repeating it with the 'Vette... This is NOT a race car, so I can't compromise on interior noise...

I agree about lubricating poly bushings, and they shouldn't squeek.
I also agree that the stockers DO have enough deflection to add to your wheel hop issues.
I ALSO agree that at least the stock tranny mounts need to go.
I DO NOT agree with the price. I'm waiting for a $90 PST kit or I'll figure something else out. Not worth $400+$300 for trans bushings -to my budget anyway. No way.

Only replace the rear lowers. This will decrease labor time and the once every couple month lube job on them. This is the bushing that gains the most in terms of wheel hop without the extra added noise-harsness-vibration. We have done so many rear lower only installs it makes my head spin. Most gain-least drawback in a street car!!!

i came to the conculsion that new shocks only help if there is something wrong with your old shocks, aka leaking.. i just put bilstein hd's in,, maybe they are too soft. inprocess of installing the pfadt engine mounts, goto youtube and look at the video they have for them. any increased vibration will be livable.. only time will tell though.. i just need to find the time to throw them in.

I did a full polyurethane suspension kit on a Fiero GT, the car was unreal it was driving a go cart, it would outhandle my c6 at slow speeds tight corners, but of course with only 140 tired hp not much on top.
anyway i would have done it to my c6 but i couldn't find any kits i liked.
