Sorry im a little late to this thread. As kentiiboii said speak to speedshack in west drayton and theyll sort out all the spacers/nuts/bolts/studs youll need for about £100-£130 depending on what you want.
Steve at speedshack spent a long time with me measuring up what was perfect for a set of these wheels.
Technically you need 13mm spacers ad the 306 uses ET18 wheels and the challengers are ET31 so 31-18=13
15mm spacers are the easiest to get hold of and anything smaller just looks wrong but 20 or 25mm spacers can look pretty awesome.
As for the stud conversion, they have to go into the hub by 8-9 turns, its a 1.25mm thread pitch so 10-12mm plus the width of the spacer plus the thickenss of the wheel plus going into the nut by 8-9 turns.
Alot of us are using "Toyota style" wheelnuts as they are a better fit than pug nuts and come with a harder to round off 21mm head.
Mine were a special order so they had the pug M12x1.25 thread machined in them but everyone else uses the toyota M12 x 1.5 thread but this means you have to use studs that have a pug thread at 1 end and toyota at the other.
The benefit of a stud conversion is it makes it alot easier to get the wheels on and off as they sit on the studs and dont fall off when you reach for a wheel bolt. It also means if you f*ck a thread the chances are itll be the stud (thats easy to change) and not the hub itself that isnt so easy to swap.
Hope that clears everything up.
