Converting to studs.

[Mack182]

I'm thinking of converting the Clio to studs and nuts rather than bolts.

Want to run 10 mm spacers on the rear and 15-20mm on the front.

If I was to buy 50mm Studs would this be enough thread for the spacer,wheel and nut ?

Any one had any opinions or experience with this sort of set up ?

thanks
