hey has any one looked into changing the wheel studs over to longer ones so as to fit spacers so you can fit wider wheels with different amounts of offset?

I have some 75mm extended Scooby studs for mine mate. Needs the hubs drilled out to 14mm, and job jobbed. They are the same pitch thread, M12 x 1.25mm (or wtf it is).

This is the best alternative there is. Have a search, it's been done or spoken about before mate.

hey does any one know the length of stock 360 glt studs?

I THINK its 43.5mm overall. I've just replaced two of mine. Got subaru ones that were 63mm long then drilled the hubs 14mm to accomodate the 14.3mm dia. splines. then just cut them down level with the other 2 on the hub
