I have been thinking and discussing with my colleagues at work about trying to get my studs out fo the hubs and replace them with bolts.



Main reasons are the ability of using adaptors for certain wheels (don't go flaming me now, the company uses adaptors for EVERY wheel they sell and have a patent on the concept). This will widen my range of wheel choice (I'm in Europe and Rays,Volks and similar have next to no dealerships and are way expensive)



Secondly I might be able to use 'spring bolts' to be able to fit wheels with a different (but close) bolt pattern. This is option nr2 considering the power of the 7, safety etc etc.



Anyone done this? How did you do it? Was it difficult?



Thx,



Neal

in theory this is really simple, reality though might be a little different.



the studs get pressed into the hub, so the holes are already too big to thread to the stock stud size. the other concern is weather the hub is thick enough to be threaded. the stock studs are pressed in from the back, and have a shank? thingee? to hold it in.



drilling new holes in a new bolt pattern is no biggie though

Thanks, I wonder what happens when somebody breaks a stud or the thread gets worn. You need to replace the whole hub?



Having a new bolt pattern drilled depends on the amount of material on the hub.

when you break one... you knock it out and insert a new one. To do what you are talking about you'd need to machine the holes in the hub out larger and have an threaded plate machined to fit in the backside of the hub (where teh heads of the studs are located now) ...Seems like a **** load of work to me.
