Yes very nice workmanship Automotivepc thank you for  sharing. 

Just curious,  Why such large diameter rollers and heavy gauge rollers ?

What vehicles are you testing ?

if rollers are bigger, less tire deformation.

I was wondering what did you use for joint brake with roller shaft? 

Looks pro!
