I am doing the ATS/C7 Brembo upgrade on my Formula and need 15mm spacers/adaptors. I was looking for the style that have new studs built into them and you can just bolt on and go. Looks like options are pretty limited for our bolt pattern and center bore in 15mm.

I see a few on here have had good luck with the ones from motorsport-tech.com, such as these: http://www.motorsport-tech.com/wheel...ers_pop_car_d3

After shipping they would be $145

Ebay has these for about 1/3 the price: https://www.ebay.com/itm/2-HUBCENTRI...5aBQBb&vxp=mtr
Normally when it comes to car parts I stay away from "ebay off brand" stuff, especially for something like these that could really ruin your day if they broke. That being said they claim to be made of T6 Aluminum and have 10.9 bolts.

Does anyone have any experience with either of these or any others? I am trying to avoid swapping out my current wheel studs if possible while still having a safe product that won't fail if I have to hit the skids from 120mph+.

I vote longer ARP studs and 15mm Eibach spacers (which come with press in studs but I don't use them). The spacers have proper bore/hub.

I was never a fan of bolt on adapters.

I went with the Ebay hubcentric spacers and ARP harden studs. I knocked out the studs the ebay spacers came with and used them like spacers instead of adapters. See my build thread for images if needed.

I read a couple reviews on eBay that scared me away. Saving $150 isn't worth the risk. Ended up ordering some eibach ones from strano, can't wait to get them on!
