Quick question with spacers

fritz

Pity about the double posting: it happens. (and may happen again as this post was rejected earlier for some reason.

More "Spam":
95% (that's very conservative!) of cars have hub-centric wheels. Taper seat nuts are
very common (even as OE on a 350Z) but it makes no difference. The hubs center the wheels, period.

Some heavier Toyotas tried it different: move to Toyota TSBs for the subsequent dramas...some (many?) of the dealers did not have the balancing kit !!

"Melting plastic spigot rings?" Quite so!!! Amateur racers would have spares. Once the plastic has done its job (wheel centering) the wheel is already bolted up and the lousy plastic ring can vaporize! It has done its job, to center before tightening.

Professionals would have metal spigot rings or the correct wheel/hub centers........
Tech inspections can outright reject wheels not hub centered, especially if spacered,,,,,, if they find them......

The abuse "problem" has become so endemic that some areas, in the EEC for example, have tried to ban wheel spacers altogether, which is grossly unfair to correctly engineered fitments......

One has to exceed posted limits (say 80 MPH) to really feel problems but a very experienced tester will know much sooner.

Metal spigot rings not available? Turn 'em up on a lathe...easy

Sorry about the "Spam" !
