Anyone running these

 

Looks like a knockoff of the spoon rigid collars. Supposedly they are a good mod. Probably only half the price too. I wonder if they properly compress like the spoon ones do?

 

Where did you find ?

 

they are just the exact knockoff.

 

I've considered these diff mount collars for my race car but I'm worried about what problems that could be caused by having the diff mounted so rigidly. Anyone know of any issues?

 

if for the subframe, they don't do anything.

Keep your subframe bolts torqued and it'll save you $250.

 

Rob from Experience I have the diff collars and they have caused me no issues. However what’s above is the rigid collars which go between the chassis and sub frame. I have talked to few Chassis engineers and they have confirmed that these above could help depending on how off the chassis of the car was when mated to the sub frame.
