If you have 20+ shops building S/C dragsters and 3 or 4 building tube axles for Nos cars, that would qualify as most.
Again back to my earlier post, I have at my shop P&S, SPE, M/W, OEM Anglia and Strange spindles, using the same fixture and same digital angle finder to measure within the same 15 minute time period and the Strange is the only one that is different by 1*. I install a new set of Strange spindles on a fixtured axle and get Negitive camber, swap out with a set of SPE's and I get .5 deg positive camber(how I designed it).
The Strange spindles are nice parts and will use them upon request, I just have to know about it first. The other thing that bugs me about them is that they turn down the OD of the spindle boss to an abscure dimention and cannot use my hole saw to get a nice fit, probably have to get one custom ground just for those.
