Dumb question but do I have enough caliper clearance?

[Jabbit]

Running 16x8 38mm rpf1s from Oakos - https://www.oakos.com/ENK-379-680-3438BP.htm

Also running the Whoosh Big Brake Kit 16" version with 300mm rotors - https://whoosh-motorsports.myshopif...it-2014-2019-fiesta-st?variant=34787663610018

I bought H&R +10mm spacers and extended lugs. Installed the lugs but it looks like I can run the wheels without the spacers. Took some pictures but does this look/sound right? It would normally hit the face of the caliper on the spokes or the outside edge of the caliper on the barrel? Neither hit.

I have the Porsche Carbon Ceramics on the GT4 and they have more clearance than you're showing. It's typical to get rocks/pebbles trapped between the caliper and barrel, resulting in scratches around the barrel of the wheel.

I can't say for sure it's not enough clearance based on the pics or that you'd have severe problems, but that would make me concerned based on my experiences with the slightly more clearance that I have.

It could also be the perspective in the photo. But man, the caliper/barrel gap seems nonexistent.

Depending on the source, 2 to 3mm is the usual minimum recommended gap between caliper and wheel. To prevent contact in case of flex of the parts under load and thermal expansion.

any updates on this? have the same wheels and be really impressed if they can run the whoosh brakes w/out spacers.

I'm still a few weeks away from being able to drive the car, waiting on other parts. I got some 5mm spacers in the mail but I really don't think I'll need them. I'll try to get better fitment/clearance photos this weekend.

If it is very close, I use feeler gauge to accurately measure the gap.

Let us know what you found, as this looks like a very interesting brakes-wheel combo!
