Suspension Bushings

**FMBL** · 01-23-2011, 09:24 AM

I have a 98 z28 with 183xxx miles. I would like to go trough and start replacing all of the suspension bushings. I would like to go with more of a stock type bushing. The car is mainly a DD with the every once in a while need for speed. Where is the best place to get factory type bushings or is there a better alternative without going with poly eurathane?

Honestly, for the price difference and the fact that you are doing essentially the same work, you may as well upgrade to aftermarket LCA's and a panhard bar in the back. They really are an improvement. Check out UMI's site: UMI Performance Any reason you really want rubber bushings that deteriorate?

I have heard/ read alot of complaints about the poly bushings squeking and being to stiff.

I have run our car 3,000 plus miles since installing all the UMI components in the rear -- not a squeek. They come with grease fittings.

OK. I looked at the packages they offer. Pricing is not that bad. How important is it to have adjustable components for a DD? The car is lowered.

It's nice to re-center the rear end with lca's and a panhard bar. If you are on a 275 tire you can get away w/o the panhard bar but when I had 18's I had to get adj lca's to keep them from catching the fender since the rear schooched forward.

Thanks everyone for the recommendations

Replacement polyurethane bushings can be squeaky and this is because they are not greaseable. When you press new bushings into your factory control arms you have no way of getting grease to them. Aftermarket control arms like we offer cure this problem by using fluted greaseable polyurethane bushings. The grease enters using a standard grease fitting. With this type of set up squeaking will not be an issue. Also for the price of new items it is almost cheaper in some cases to purchase new aftermarket items (depending on what you think your time is worth)

Here is a link to just one set of control arms to show you an example of price and greaseable bushings- www.umiperformance.com/2015

I hope this helps,
Ryan

I did the Energy Suspension set.. Cost me about $160 for the whole car and about 2 days of my time. Lots of grease no squeaking

2 days? You beat me by about a week.

I had a Leister hot air gun, lots of beer, no friend.

Bilstiens shocks front and back, new strut mounts and UMI LCA's and Panhard bar are on the way.

Don't get the QA1 endings, get poly/grease...I got the others just because they were on sale and they rattle more than the rest of the car does...good thing I have a good sounds system
