Where to source Polyurethane or Delrin Bushing Kit?
 
I'm looking for a complete set of bushings for the car. I've had great experiences in the past with SuperPro bushings with my rsx. Yet being on this site, it has come to my attention that they are no longer in business. Their website is still up, so I'm not certain how credible that information is.

If this is indeed true, I was wondering where to source replacement Polyurethane or Delrin bushings for the FD?

Search here and in the suspension section on posts from howard coleman on bushings. Stock is more than adequate and Delrin is really too stiff for everything but a dedicated track car. I'm running the SuperPros fwiw but if I couldn't find them I'd be happy with stock.

Thanks for the response. I have been searching, but the results I came up with are about a year old and didn't really answer my question.

I've asked around and it seems they are still available through their distributors.

It seems upgrading bushings is a typical and frequent modification. Why is it people don't replace/upgrade the existing suspension pieces that come with better bushings?

Just b/c its a year old doesn't mean anything has changed to make them irrelevant.

The SuperPros polyurethane and Delrin bushings aren't necessarily an upgrade. They are made of different materials that are stiffer than stock. Stock is rubber and of sufficient hardness for most, poly is slightly stiffer and Delrin is stiffer than the poly. Is stiffer better? Not always. It depends on the application and the user's needs.

Many knowledgeable people (including a championship SCCA racer howard coleman) have opined that the stock bushings are more than enough. Search on his posts. Others have different opinions but not all have his credentials.

The FD isn't like other cars that 'need' stiffer bushings to take the slop out of the suspension. In the end its up the owner's discretion to choose what you think fits your needs best. Sourcing the polys are difficult these days. No one seems to have them. Not sure about the Delrins but the person who used to offer them has/had a thread in the Group Buy section.
