Does anyone know where i could get a polyurethane bushing kit. Shark racing has one but its out of stock. I didnt know if there was anywhere else i could get it. I have a few bad bushings on the front A arm and this would be a nice upgrade.

Why do you want them? Polyurethane is crap as suspension bushings. What happens is they stretch and sag into an oval shape. Honda guys don't use polyurethane anymore after they noticed what happens to them.
Hard rubber is the best to use because it doesn't "set" like poly, too bad there arn't any for our cars. I plan on making me some when the time comes.

Ya i guess. Ive never heard anything bad about polyurethane untill now. Not saying hes wrong just saying i know people with them on chevy 1500, cavalier, and a camaro, and they have had no complaints. They love them.

Don't get me wrong, they are great stiff bushings but they don't last long. They'll start to sag and not regain their form, which defeats the whole purpose of them. Go check out honda-tech and search polyurethane bushings, they've done extensive research on them.
Hard rubber is the best between stiffness and longevity. There's also another type of bushings they swear by that is a different compound, appearntly better then all, just can't remember their name.

To be fair, there are different hardness (deformation-resistant) levels of polyurethane - measured in "shore". Unless the manufacturer specifically states it, you have no exact guarantee of what hardness you may be receiving.
You want something that is hard and will resist deformation, but you also want something that isn't rock-solid or else you will vibrate yourself to death. A good number is between 75 and 90; I used 80-shore polyurethane in my rear control arms when the stock bushings seized to the carrier bolt.
