I never considered the torque multiplier, but it looks interesting. I bought a centering tool from a RL member named SmokinGTS. It's made of delrin, and it's much less expensive than the 3R Racing version. I'm not familiar with the BMF torque wrench.

Centerlocks definitely add a "PITA" factor to wheel changes, but I think it's worth it for the look.

Sorry, was being a bit flippant.... BMF = "Big Mother F...." torque wrench.

Multiplier adds 20% error. Good luck with that.

Got it. In that case, I did buy a BMF torque wrench!

Documented where?

They do have a 10% frictional loss, which is why in the above example they list it as a 3.6:1 torque multiplier... Mechanically 4:1, -10% frictional loss, resultant 3.6:1.

i use what's recommended by Porsche literature. It's not that bad. 450 lbs. I have also read that just the torque wrench alone has tolerances. That is why that also gets computed. I don't use a multiplier. I have one.

Not trying to be argumentative, just accurate. I believe the Porsche factory motorsports centerlock tool, 00072194500, is a torque multiplier rather than just a BMF torque wrench, so to imply that Porsche doesn't recommend the use of a torque multiplier is inaccurate.

Also, torque wrench error is usually expressed as a percent, so yes, putting it through a torque multiplier and torquing to ~400 ft/lbs will increase the absolute error, but it should not increase the percentage error...

"not trying to be argumentative " of course not that would be beneath this wonderful collage of opinions on this forum. LMAO. Love this place for its comedic properties and experts, I only visit to entertain myself.
