Going through a similiar fitment as you are, KICS 10mm in the front and 15mm spacers in the rear. I think the confusion for most here is that they don't know how Kics Projects Spacers look like - its a 2 piece system (a thread-on spacer adapter, and a hubcentric insert).

I wanted to do the same set up as you with 10mm in the front, but I'm pretty sure that kics only makes the hubcentric insert for 15mm and larger. Basically your front will be wheelcentric, but it won't be hubcentric - that's not good. Let us know if you have vibration at high speeds.

I'll probably get the 15mm for the rear, but get 3mm or 5mm for the front.

 

So far, it doesnt vibrate much at all right now. Im glad i found someone else with the same issue though, haha. Im considering purchasing the 15mm hubcentric inserts and having them milled down 5mm on the backside. But its an expensive trial and error... so i dunno yet.

 

So anyone know which shop is best place to buy the hubcentric inserts for 15mm kics spacer?
