Some will argue it depends on what you want to accomplish with the car.
But I firmly believe that solid/aluminum bushings will be one of the best things you can do for your car, even if all your control arm bushings are rubber.

With rubber/poly bushings it allows the front frame to flex acting like a giant spring, solid bushings help get rid of this flex and allow the suspension to do it's job better. I also recomend subframe connectors for any of our cars regardless of what you use it for, but thats another topic.

Poly subframe bushings are a waste of money though, they're not hard enough to get rid of the flex, and they get rid of the "comfort" people want with rubber.

I agree, Metal is the way to go. Global West #800 is a great bet CustomWorks also has a nice set. Stay away from the CompEngineering ones as the kit isn't complete. Be forwarned, replacing subframe bushings is a nasty job. Rush it, start blasting away with an impact wrench, and it turns into a much worse job.
Great writeup guide here

Agree with the solid mounts as they get rid of alot of flex, and are good forever. The ones that I have replaced, the very rear ones, you cant see the nuts. These are the ones that caused me the most problems. If the bolts all come out, great

Good, solid (pun intended) advice from SPG and Lowend. All my suspension modifications are Custom Works.

I got my solid bushings from PTFB. They're adjustable so you can change the spacing between the body and frame. It's worth noting that Chevy ditched the rubber bushings and went solid with later generations.

I went with solid aluminums also.Was a no-brainer with subframe connectors.
Im a blue fan,so I went global west.
Also like to use grade 8,and they're cheapest at Bolt Depot online.I just stick a pencil in the hole to get my length of bolt.

If you plan on going with lowering spring and a lower stance.. do you need to change bushings? I just noticed on the global west site there was a stock height and 1/2 inch drop. Would be a pain to have to take them out and do it again!

I staid with standard height bushings, I don't have the under hood clearance to play with. My front suspension has Custom Works 2" lowering springs. All is good.
