What is there to gain? ~$900 in your pocket.

There are some recent threads going into lots of detail on symptoms, but if you get that "warped rotor" feeling but your brakes are fine, that's one possible sign.

Same questions here too. Have a slight wobble but suspect brakes which I will be doing here in the next week or so but very interested to hear more about this.

Not sure if Chris is on-line this week as he is in the UK.

In Chris' absence, here are two of his videos on Youtube showing the before (rubber) and after (poly). He pointed out the wheel "chatter" in the first video.

Chris- did you pass around some prototypes at Callas last month?

If so, I didn't know it was you. Either way, well done, and I will be doing business with you!

I use a press with a series of press tools I machined-up at work, but its not necessary. The DIY I wrote uses typical hand tools found in typical home garages.

Since the DIY file is too large to post here, anyone who wishes to see it please email me at tangentautosport@sbcglobal.net and I will send it over. Those who purchased the bushing kit, I will be emailing the DIY shortly

In the few cars I have installed urethane bushings, no real difference other than a slightly more direct feel

The folks who mold these bushings for me use the 95 durometer urethane for all of their suspension bushings and have been doing so since the early 80's without any real trend of wear, so they assure me.

Yessir, that was me

I leave this Wednesday and will return the following Tuesday. I should have email access throughout the Motorsports convention.

Good question.

With a large prybar or the like, pry between the control arm and the subframe mount. I have painted a red mark to illustrate the location in which to pry.


While prying, have a look at the forward bushing front side for cracks like this one:

Yes, his car was due. Poor Long_Beach_968's car got beat up upon a little. The good news is, his car just needs a little attention and otherwise a solid example!

Thanks for your answers Chris. I will check my front control arms this weekend. Something's a little loose up there--although it could be the tire rod inners.

I would expect that the urethane would transfer more road harshness to the frame, although not as much as say, Delrin, which I used on several cars when I was racing SCCA Nationals.

That said, it's hard to pass up a repair that saves hundreds and, oh by the way, makes the car a little racier.

Chris Im in. Just sent you a PM.

Chris I can host you some space on my FTP site. Gimme a shout and we'll take care of it.

chris walrod

Are you sure Scott? The file is 6 terra bytes I'll send an email with the file attachment.

Thanks!
