Going to buy a set of H&R studs but the vendor needs the specs for them. I will be running 5mm spacers all round - can anyone tell me the spline diameter and overall lengths for the studs that I'll need? All I know is they are M12x1.5s

I had a different set but they were poop and sent them back as the head sheared off on a test-fit. TXW's UK dealer doen't have any in stock so they're out of the equation too.

Thanks in advance.

 

I know the studs I just installed on my wheels were M12x1.5 / 22mm length without any spacers, so Im sure a 27mm length should be fine.

 

Thanks ***** - I'm just stumped on the spline diameter thingy - does it even apply to MINI's?

 

It shouldn't. Since our cars come stock with bolts, the studs need to be threaded on the end that goes into the hub. On cars with hubs that came with studs to begin with, they will probably be splined for the studs to press on. On our Formula SAE racecar, we (I) make the hubs from billet aluminum on our cnc. The holes where the studs go are drilled to a precise diameter so when the studs are pressed on, the splines will cut their own grooves into the hub. You should not be looking at studs that are splined on one end.

 

Thanks Kapps - after a bit of research I came to the same conclusion, the initial question from the Vendor just threw me.
