Can you fit 10mm spacers to a 172 with the origional wheel studs or do you have to get the bolts?
rule of thumb i go buy,
if the bolts goes round 360 degrees 8+ times, it will be fine,
though i counted 11 with my 5mm spacers so not sure if that even helps.
You will indeed need longer bolts!
10mm spacers aren't hubcentric though so wouldn't be as "robust"
