Hi folks, need some reassurance/confirmation I'm doing the right thing!
I've picked up some Bimecc spacers for my Leon - and gone for the tried and tested (and often recommended) combo of 12mm's front and 15mm's rear.
I ordered a kit that said it came with the 12+15mms, 16 appropriate longer length bolts and 4 longer locking nuts... The kit has arrived and all the supplied longer bolts are 40mm long.
My understanding was that the longer bolt should be at least the length of the original bolt + spacer... I've measured one of my existing ones and make it as 27mm long? (thread length) - so for the 12mm spacers that's 12 + 27 = 39mm, so the 40mm bolts should be fine as long as they don't rub where they protrude behind the hub?
My issue is with for the 15mm spacers - as 15 + 27 = 42mm. So the new longer bolts for the rears will be 2mm too short.
I'm thinking this is a deal breaker, and I should go back and request longer bolts for the back? Or is 2mm short fine? I can't tell if there is excess thread length on the OEM bolts... Will 40mm give me safe enough depth to secure the wheels, or do I need 42mm minimum, maybe even 43mm to have a small excess?
