I personally don't think very much of them, however I have them for my Granatelli crossmember in my 93 FOX. One of the first things I noticed was that the rack bushings really don't index on anything, they just hang out on their own. I was thinking that might be OK for an drag racer but they don't look too solid for an autocross or roadrace car. Secondly, the crossmember is not dead nuts square and the aluminum rack bushings seem to be placing undue stress on the rack itself. for this reason I'm thinking of going back to delrin or stiff rubber stock type rack bushings and using a bumpsteer kit to solve the issue with the spindles.
Any input?

 

They do sell solid aluminum rack bushings.

 

Id get rid of the Granatelli K member personally if youre looking for quality

 

They are aluminum

currently the budget only allows for MM knockoffs.

 

And they still move? Hmmmm

 

I didn't say they moved, I said they look like they would move. The cams (spacers, whatever) fit into the rack and are rotated so the rack is at the highest point. But there is nothing to keep then there, I would have thought there might be some sort of dowel or something to keep the rack indexed at the top. I may even drill a hole in the K-member bracket and drive a roll pin in. The issue I have is that if you bank it off of the elephant turds the tracks use to line the corners with, it could cause the rack to move.

 

That's how the bushings are. I have a real MM K- member and aluminum rack bushings and it seems like the rack would move but it doesn't.

Still no excuse for using an MM knockoff

Let me know when you want to buy the real deal - I'm an MM dealer

 

Fair enough

I didn't know that until after I bought it about 6 months ago. I knew I didn't want a UPR, the Granatelli looked pretty beefy. I know MM and Griggs (and maybe Agent 47) are the gold standard.

 

Team Z K-member...Now where near as much as the overpriced MM stuff and this stuff is GREAT!

^^I dig TZ for drag racing but for corner carvers it's hard to beat MM.
