These seem to be moving. Is there any PM I need to do here? Or is this what a high dollar bushing kit cures?

I'm a basic HPDE guy running about 8 days a year.

Thank you
Dan

This is normal, it will just keep getting worse. Bushing kits fix this issue.

You should check your lowers as well. My uppers don't look as bad as yours, but my lower arms are nearly touching the subframe from heavy braking.

I have the same issues and had them replaced once under warranty. Now, I am going to replace them with the Ridetech Delrin kit.

I went with pfadt poly and they work well, but would definitely go with a metal or delrin bushing setup if I did it again

Why is this? Would like to here your first hand thoughts/experience on why you'd go harder. Do you still drive your car on the street? Also, where do you live? (Road condition)

It's not that most don't understand the reasons to go Delrin or mono, but if one is still going to street a car - it would most likely be too harsh for most. We'll - at least that's the common belief. The only car I ever had metal in was brutal here in the Northeast and went 100% track eventually.

We sell the solid spherical bushing kits if you are looking for the ultimate fix.

PM me if you have anymore questions in regards to our kits.

The Pfadt / aFe poly bushing kit is by far the best solution for a guy that does 8 track days a year. This guy doesn't need delrin or sphericals.

This has been covered pretty extensively, here is a thread that deals with it...

https://www.corvetteforum.com/forums...s-options.html

Bottom line is that it is the arm that is deforming and pulling off of the top bushing. This happens because of the braking torque tries to pull the top arm forward and the arm bends.

The easiest fix is to get a set of new arms and flip the rear bushing as described in the thread above. There are detailed instructions in the thread as to how to do it. It only takes a few minutes to flip the bushing, and you can do it with no special tools, you just need a vise clamped to a bench and you can spin the bushings out and back into place in a few minutes. If you wait until the arms are deformed a lot it will work but you will have a ton of caster because the top arm has bent. The drives side arm looks pretty bad and if they were both like the passenger side I'd just flip the bushings and be done with it. If you wait too long (like the drivers side) then it's replacement time.

You can flip the front lower bushing too to keep it from walking out. Its not as bad or as apparent, but it does happen. You'll need a press for that job though.

I flipped mine on my front uppers when I noticed them starting to push out. Now my driver side front bushing looks like this. Assuming the arm is bent.

I see the Pfadt poly bushings are available again, this was one of their products that didn't suck correct?

hklvette

On the front upper arm, is that the front or rear bushing? The "flange" should be towards the front of the car regardless of side. If you put the flanges to the rear, the bushings will push out very quickly.

flyby763

You had me worried, I had to go check to make sure I didn't have a brain fart. That's the front bushing on the driver side, so the flange is at the front. All 4 flanges are on the front side.

Thank you for the help guys. I'm happy to hear there is a basic swap I can do to help this out. Not really wanting to spend 2g's on bushings just yet...

Supercharged111

Mine are all 4 facing out, so the fronts are in front and the rears are in the rear.

This delrin bushing kit is a significant improvement over stock

http://www.ridetech.com/store/c5-cor...shing-kit.html

This delrin is 13% ptfe (teflon) infused so no lubrication, no squeaks, no wear.

Soloontario

The front LCA bushing is where I have the most trouble. Also as it slides out, the car loses caster. How easy is it to flip this bushing?

sperkins

Correct. As long as the design hasn't changed, it's well worth the money and by far the best poly kit on the market.

Solofast

Yup, your arm is bent a bit...

Not sure if the arm will spread to where the front takes up the load, but if it did the bottom line is that you'd have lost some caster relative to doing it to a new set of arms.

That's why it's a good thing to do the flip bit when the arms are new if you're going to be using slicks or Hoosiers on the track. If you do it early then both arms share the load and they never bend. Think of it this way. One leg of the arm isn't strong enough to not yield under heavy braking loading, but if the legs share the load then then each leg has about half the load in it, and they never bend.
