STILL no bushings?!

I think SCCA requires the use of stock bushings.

the scca only requires that the bushings remain non metal, so going with urethane would be ok

yeah, i knew turboyaris was making those aluminum bushings, so that's cool. but then there's all the rest of the rubber pieces of crap that should be replaced with urethane. i would think that these would have gotten more attention?

you'd be suprised at the difficulty to get bushings made in urethane, there are only a handful of companys that will do custom urethane bushings for you. I only found one actually that will do a small run of automotive type urethane bushings, not to mention that to make it cost effective, you need to spend a decent amount of money to buy them in a larger quantity. the process first is to replicate them in aluminum or some other material, test fit them, and once you get the proper dimensions, have a negative made so that the company can just pour the urethane in and seal it up.

the outer ring is for overflow purposes.
If I couldn't make that mold, the company would charge me $250 just to make that. Plus, just to pour the urethane is pretty expensive.

If it were just making aluminum bushings, it'd be much easier for me. I am starting with the axle beam bushings, and if they are successful, I will start on some other bushings, probably doing group buys, so my up front cost isn't as high.

Have you looked into delrin? BTW, What size are those rear bushings?

Word.

okay so the part numbers are different, so i will have a request for you so that i can figure out if they will fit.... what are the physical dimensions of the bushings in question?
