Greg,

My street use is probably a lot different than most peoples, so I can't speak on his opinion. I can say that my 95 drives TONs better than my 94 with the new poly in it.

So the drm and and camber brackets made a difference in weight transfer on your car?

I am looking to do whatever I can to get my car to hook up and we have similar set ups and make around the same power to the wheels as if now. I remember reading a post of yours where u were having trouble with your car cutting out upon hard launches. Did you get that worked out? I know my car will not hook at all in first or second gear amd I have 315s but they are not DR's. Obviously thats going to make a huge difference.

Greg- I was told that the polly bushings are to stiff and make a lot of noise on our c4s and even on the c3s. Thats why I made this post. I havent installed polly in any corvette but I can see where that could be true. Obviously polly is a lot stiffer than factory rubber bushings.

That’s interesting. I didn’t know you could actually get our vette’s up onto 2 wheels going around corners!

I’d be up for hearing the differences in the two cars.



Edit: Sediment from 3 engineer/hot-rodders at my office seems to be consistent. They are all apprehensive about putting aluminum bushings on a street car. They feel high odds it would be like riding in a little-red wagon....You know something without any damping. One guy joked that I'd probably be able to feel the stripes painted on the road -- as I crossed over them!

My vote would be rubber for street and stock class autox and heim joint ends for upgraded suspension.

I looks like posters are right though....I don't see rubber available anywhere. Because I never found a negative post on PolyGraphite, I'm leaning toward that.

I just have to ask why are people spending hundreds to thousands of dollars to essentially replace bushings on a car that is driven on the street?

I clearly stated my reason in post #16. I suspect tighter response and reduction in "slop" would be the primary reason for most/all street-driven cars.

Track...well you can figure that one out.

My car is not only street driven but also driven on several different tracks varying from Road America to autox to the strip here n there.

My car is only used on the street but the Banski set completely changed the way my car rides. I no longer slow down for railroad tracks. The reason I spent that much money was to make the car ride like it should have from the factory. The rear design is great they just used lower priced parts for production purposes. Now it handles better and rides smoother then it did brand new. Well worth the money and work I put into it. I recommend it to anyone that is not happy with the ride they are experiencing from their C4. Poly every where else and adjustable shocks. Grease the poly with never seize to eliminate squeaks. Set it for your ride and handling preference and enjoy your car like never before..
