I was going to buy somehubcentric wheel spacers but my mechanic said not to get the bolt through ones but to instead get the bolt to hub ones? Is there a difference and is he right. If so what should I be looking for? I'd found some with the long bolts for £60 20mm are the bolt to hub ones more?
technically, I guess there's 3 types, 1) bolt-through, 2) with studs for wheel nuts, 3) with threads for wheel bolts..
It makes no difference wether they are bolt thru or bolt on. You will most likly find that any that are larger than 20mm are bolt on and less than 20 are bolt thru. Id go for h and r or eibach not cheap ebay ones.
