Wheel Stud Question

[GrayGen4]

I bought a set of 16" wheels from TireRack. Their configuration page said these wheels will fit, and technically they do, however when I put the lugs on the rear I'm not real comfortable with the amount of thread I have to work with (maybe 3-4 turns). Not sure if this is a fault in TireRack's database, since the 4cyls have drums in the rear. This isn't an issue for the front wheels, they seem fine.
Anyhow, my question was if anyone had used the wheel studs from the front on the rears. They're about 4mm longer, and have similar measurements according to the manufacturers website...just wanted to know if anyone had successfully used them before I go out and buy them. If not, anyone know where to get longer studs for the rear?
Specs: 2001 Camry LE, 4cyl Auto.

Thanks!
