Hello, does anyone know what the wheel stud length is on the back wheel hubs on a 1999 GT. I was looking at spacers, but they must be deeper than the existing studs or you have to trim which I dont want to do!
I just called MM about this! (I do not think there is any difference in the stud length between the pre- and post-99 model years). The MM tech told me that for 25 mm spacers, I will need to trim about 1/4" (6 mm) off the studs. You can try 30 mm spacers but you have to be careful about the outside edge of the tire rubbing on the fender lip. When I measured the gap on my '98, I was right at 30 mm (so I went with the 25 mm adapters).
If you need to trim them, you can use a hacksaw or you can rent a die grinder and pick up a couple of 'cut-off' wheels at the hardware store. You can also get cut-off wheels for a Dremel but I think the job will stretch into several hours!! Put a nut on (all the way to the hub) before you cut. Then, file or grind the freshly cut part, use the nut to chase the threads, and you should be good to go.
Hey guys, I confused... a spacer is like a large washer used to move the wheel out just a bit. I'm attaching the pic of my MM 25mm spacers...rought 1/4 inch.
You dont trim you studs after a spacer install...in fact you have to make sure you have enough stud left to get 8 full revolutions on the stud.
Adapters on the other hand do bolt on to you studs and you trim your studs back so they dont interfer with the new stud ring that the adapter has.
Yup, you are correct: I (and, I think "robg860") was talking about the hubcentric wheel adapters (25 mm, close to 1"), not spacers. Sorry about the sloppy use of English. Spacers are not wheel adapters, to be certain.
