Delrin bushings

Hi, ordered some spc upper control arms from Mark Savitske, got them last year, had to wait 4 months to get them, seems they had some issues at the plant....I ordered them with the Delrin bushings, what I got was the High Durmeter rubber bushings.

Contacted Mark, said he would exchange them, thought I would do this switch this summer, well do to the "virus" issues, seems like I have to wait another god knows how long for this to happen.

Mark says not that big of a deal for pretty much a street fun car.....and if I do want to exchange them, im on a long waiting list for stuff.....

Getting tired of the old run around, just wondering if anyone is running the high durmeter rubber and happy with it, would like to get the car rolling soon.


I see doing some search here, seems like your either in the umi camp or the spc camp......I wonder if there really isn't much difference between the two.

Looking for any ideas on how you would handle this

Thanks

Rich

Re: Delrin bushings

The uppers aren't that difficult to remove and change the bushings later if you decide to do so. And if you did you would have firsthand experience of the difference.

But I doubt you will ever second guess the rubber bushings.

Re: Delrin bushings

know anybody with a lathe? you could cut your own Delrin bushings. I think you have to keep the inner steel sleeve to keep from crushing the Delrin.

Re: Delrin bushings

I'm running the rubber bushings with no problems at all. Torqued everything to spec and am rolling. You'd be better off reaching out to SPC directly instead of waiting on Mark. He's a great guy but I'd never do business with him.

I hear ya on that one Hotwire.....im having 2nd thoughts on this whole adjust spc arms, wondering if I should just throw on some umi uppers & lowers and call it a day.

Other choice I have is use the spc uppers with the howe ball joints and use my stock lower arms with the howe joints I got from mark.

Thanks for the help guys

Re: Delrin bushings

Do yourself a favor and call SPC directly (if they aren't shut down due to covid) and tell them the situation. That will get Mark to move on it quicker.

Re: Delrin bushings

Honestly, unless you are going to autocross or track the car, the high durometer rubber will be fine. In fact, if it were me, I'd go with the rubber anyway for this particular location in the suspension.

Re: Delrin bushings

About three years ago I ordered SPC uppers with Delrin bushings.

They sent arms with rubber bushings installed AND the delrin bushings loose. It took a minute to install them.

If you get the Delrin bushings, the cross shaft nuts just get turned in to snug. Any tighter and the arms will not move. This is by design. The nuts are lock nuts.

I understood you meant a-arms, that's what I was responding to.

Here's the rubber bushings and adjustable a-arms at work: https://drive.google.com/file/d/1TEL...w?usp=drivesdk
