I have those brakes and wheels on my car. As soon as I mounted it up it was way too close for my comfort. I promptly ordered some 5mm spacers. All is well.
If it comes up in the future don't go nuts on the pre fab spacers have a thin one cut for you at a waterjet shop. I supply a .090" one on my Marauder kits for example. They can do .032 .065 and .090" from alum real easy for you.

That's about the clearance I had with the C6z calipers and the TSW's. The 18" x 10.5" C5z wheels (rears on front) wouldn't clear without an 1/8" spacer.

wow. that's crazy! i went back and forth on c6z calipers and now i'm glad i stayed with wilwoods. I was worried about wheel clearance. i have like an inch or two with the wilwoods and tsw's lol.
So with the upgrade I did its 4 piston front and rear with stainless lines and heres my thoughts.
this is how the car should have come stock. It's still using stock diameter rotors so you aren't gaining any leverage or heat dissipation.
the positives of this setup are:
very precise pedal. It's as direct as you can get. I absolutely love the feel. No take up. It doesnt feel like you're pushing on a balloon between you and the brakes. That spongy feel is gone. They're just there it's like you're sticking your foot straight to the rotor. And theres PLENTY of stopping power for the effort.
quick change pads
looks fantastic
for 1500 bucks I couldnt be happier I was going to do powerstops yo replace what was there but I think it was 400 bucks for pads and rotors so I'm 1/3 of the way there (in my head) and I hate the way stock calipers look. I dont like them painted (other than black). I just wanted that higher end look and feel and the benefits of having that precise braking.
once you get into some 6 piston fronts you get some more dramatic performance increases but the price also increases as well.
I never get tired of the way this looks with them peeking out of the wheels... it's the look that caliper covers go for and fail miserably at achieving
Quick pic of mine running 5mm spacers all around on stock bolts. My fronts cleared with about 1mm and the back had miles to spare just wanted to "square up" the track width.
I have OEM calipers with HPS pads. No sponginess at all, a good hard pedal and very easy to modulate. That "spongy" feeling was probably because your brakes needed bleeding - air or ondensation in the brake lines will do it every time.

probably has more to do with the stainless lines. Maybe spongy is a bad description mine didnt feel like they needed bled. But there was more pedal travel vs these.

wilwood 4 piston brakes and stock thin 5 spoke wheel clearance (pics)
That's close!
