i 2nd this,
To describe how strong powdercoat is, I got my BBS RS wheels done in silver powdercoat and the middle waffle centre plate was done also,, whilst putting the waffle plate on the bbs wheels it didnt fit perfect because the powdercoat raised the backing side of the waffle plate by a few mm *i should have thought about this before i sent it away so i didnt need to wirebrush/remove powdercoat*
But neway i got the shits massively and i have a really bad temper so i frisbyd the plate down the backyard, it then hit the concreate , rolled onto the sandstone and hit the back shed, my mrs picked it up and it was totally fine, not a scratch.
i did chuck it pretty dam hard too ! so if it can survive that, it can survive plenty xD
wheels are on the car now and fit perfectly... haven't regretted it at all.
