I never heard about the Genesis coupe calipers not working, how would one know what they have?I am attempting this setup right now with my Konig Freeform 18x8.5 ET35 wheels The following pictures are with a 5mm universal spacer. For reference, the same wheels in 18x9.5 ET35 almost have an inch of clearance without requiring spacers. Rotors are spec for the Nissan Rogue with 3rd row seats - any year should work, just check they are 320x28. Genesis Coupe 340mm rotors will not fit because they are too tall.
Konig recommends at least 3.5mm of clearance to be safe, and unfortunately I didn't measure that in the first dry test fit so I will have to try again. We took off the stock caliper and set it to the side without removing the brake line, and installed this one onto the bracket without any modification/custom brackets. The dust shield has to be slightly trimmed for them to not sit between the caliper and the rotor.
If I was to go with the minimum 5mm spacer as shown, it would be the H&R 1065640 as it's hub-centric and 5x114.3. However, I'm thinking I may need to go custom and get a 6 or 7mm for peace of mind. Since I can't find any options, I would tremendously appreciate any help in finding those sizes, OR does anyone have experience with custom spacers and reputable brands?
It’s a couple hundred pounds lighter than a Genesis I want to say, so the civic already wins there. I have the conversion and with good brake pads the car stops on a dime. Really the purpose of bigger brakes and rotors is yeah more brake clamping force (4 pistons vs. 1 piston), but the main difference is heat dissipation. Able to brake longer and more aggressive without brake fade, that’s really the main benefit of BBKs. If you get good pads and rotors on the stock set up you might even get close to what a BBK does (stopped distance wise), but when it comes to situations where you are constantly braking and the pads and rotors are getting HOT with little cool down times, BBK wins every time because of the heat dissipation benefit you won’t get brake fade as fast as the stock set up will. So for normal every day use stock brake set up is perfect just get aggressive pads and blanks or slotted rotors if you want to cut the braking distance some more
No, there’s nothing in the market currently that will replace the rear brake calipers since the electronic parking brake. Last I heard R1Concept was designing a rear caliper that was able to keep the EPB, but that was last year at SEMA.. haven’t heard anything yet. The only way right now is if you want 2 rear calipers, since if you take off the stock ones you’ll get EPB and brake errors on your dash
Thanks for the reply. Damn I honestly forgot about the EPB lol. If you dont mind me asking, where did you get your brembos at? and how much did they cost?

Thanks for that! I really appreciate it. What add-ons did you get when you bought them? Like are the stainless steel brake lines necessary?
It’s not necessary but it helps for a “firm”
Fellas, update time! I knew the BBS RG406 (aka Mitsubishi Evo X wheels) I had for this year would clear, but wasn't ready for how much clearance I am delighted to report back on !
As a spot of context, here are my last year's wheels, Konig Freeform 18x8.5 ET35 with a 5mm spacer to clear the Brembo calipers, which makes them ET30. That's 2mm of clearance from the lowest point on the Brembos, after gaining 5 from the spacer - without they didn't clear.
Here are my new-to-me BBS, 18x8.5 ET38 wheels. The offset is 8mm higher, yet I have nearly 11mm (0.43in) of clearance from the lowest point on the Caliper! The reason for this is because I chose a wheel that starts off with a Convex spoke profile vs. the slight Concave of the Konig Freeform.
The BBS being of convex profile has a longer wheel mounting surface, and that pushes out the spokes helping clear the caliper the way they have.
There was enough space for me to slide my hand easily between the spokes and the face of the calipers!
Clearing the barrel has never been an issue with 18" wheels, but here's me with hands resting on top of the calipers, and still have wiggle room
My advice is that if you are looking at the Genesis BBK, look for Convex or Flat wheels. For any concave wheel you have to go to a 9.5 with a low offset, which still may not clear but it sure will poke, and very likely rub your fenders when you hit a bump.
Kinda lost with the wheel offsets but I have 18x9.5 +38mm. Do I need additional spacers from this point ??Fellas, update time! I knew the BBS RG406 (aka Mitsubishi Evo X wheels) I had for this year would clear, but wasn't ready for how much clearance I am delighted to report back on !
