lug nuts

I just got a set of RTR Aero 5 20x9.5 fronts and 20x10.5 rears. Tried putting the front tire on and the wheel studs aren’t even close to being long enough, anyone else run into this and find a lug that works with the nub of a stud?

I currently added some caliper covers and they were rubbing luckily I had some 5mm spacers laying around because they didn’t clear. The center bore on the lip is 72.6m which is incorrect CB I have flat 5mm spacers I was going to order. Just wondering if flat spacers are fine or if anyone notices...
