Hello everyone. I am running these spacers on my Fabia estate

and I was wondering if there's anywhere (ebay etc) that would stock locking 'radius bolts' (as I was told I would need this type for OEM alloys, as I have a set of Bora sport wheels I'd like to fit) that would work with spacers? 

 

Many thanks in advance

Hello again. I've whipped a couple of the bolts out, and after measuring them (you just measure the threaded part, right?) they seem to be equal length on the front and rear (35mm) would this be correct even though the spacers are different thicknesses? (I'm sure it is, just wanted to double check, as my little boy travels in the car and I don't want the wheels coming off!) 

How many threads are the wheels held on by?

 

use a speed brace if you have one and do up a bolt  counting how many turns it takes to tighten and that is the number of threads.
