Hello Simon
I am currentlly using speed mind, Sorex & yokomo rims (all dish).
I was using the single blue one but found it too tight to turning ball joint on wheel hub, I will have to check again maybe the nut contact area on rim might be a problem area as well.
thanks
jeffrey, I will look out for the Kawahara stuff.
Thanks
