I too, have the an aluminum coupler. 1 year, about 25k miles, 7 track days. Steering still feels the same. More responsive, but also more sensitive so definitely need a well calibrated tire balancer, good bushings, and good alignment

Hope you guy's don't mind me skipping most the thread but, I just wanted to mention that the current CMP aluminium steering coupler I offer is for RHD vehciles only.

Another forum member shared some measurements in the GB Feeler thread of a LHD unit he had available and the measurements do not match what we have over here.

Just to illustrate, I've linked it below.

http://cmpautoengineering.com/produc...ering-coupler/

As a side note, it appears that the LHD joints only have a single UJ while ours have one top and bottom of the coupler likely making binding much less of an issue.

Sorry if there was any confusion.

I'm running the Condor steering coupler. No additional NVH from what I can tell, just more direct steering.

Hmmm, how exactly does it attach to the steering shaft? Those look like set screws? at 90* apart?

Yeah seems like it uses set screws, which I'm not a fan of. I'm hoping the I8 or Z8 piece works (hopefully i8 since that's considerably cheaper)

Ya, set screws (when properly installed) are generally reliable, but are used primarily in industrial equipment. If one were to 'spot' the shaft where the set screws contacted...that would add a degree of confidence...but I still don't know how I would feel about what amounts to basically having some fancy set screws attaching my steering wheel to the front tires.

I would imagine that making a proper u-joint would be much more complicated than replicating the way an OEM one attaches, don't know...

And yet, for pretty much any car, I can't find an aftermarket one that mounts similarly to OE, while pretty much all OE pieces (regardless of make) have a similar clamp mount.
