Big Brakes
I’ve got 18inch wheels coming soon, and now I’m thinking about brakes. I’ve just started researching this… but I’d really like the upgrade to a 6 piston (13-14inch rotors?) front, and 4 piston (12-13 inch?) in the rear. Is Movit the only vendor with a complete bolt-on kit? Also, I’d like to keep the parking brake. VB&P didn’t have much, and for some reason I couldn't find much searching. I’ll check DRM now. I’m fairly uneducated about what’s currently out there so help me out guys. Thanks 
Lastly, let's not turn this into a how good/bad the stock brakes are thread.

Going to a different set of wheels really opens up what you can install.
The smaller Wilwoods are actually more expensive than the larger better calipers since they sell more of them.
I'd repost in the autocross/road racing section.
Some of those guys have some serious brakes.
Is this for competition? HPDE's?
Watch you comsumables, pads & rotors.

but with some agressive street/highway driving, Hallett (road race), and Texas Mile runs mixed in. As little as my car is together and (seriously) raced, I'm not overly worried about tearing through pads/rotors.

Stillen also sells a kit, well they did.. I don't know if they still do but it's the Brembo F40 kit. Priced around $3400.... The kit i'm selling comes with larger calipers and pads.
Here is a picture of the F40 kit sold by Stillen and the replacement 6s1 caliper setup from movit

Here is a link to the two kits they offer. The one I had installed on my car was part number 305420. Price has gone down a few hundred dollars...

The new 6 piston Baers are suppose to fit the stock wheels if you used the stock rotors, it's also half the price.

There's a printable template to check, pretty slick!

This is what my front Mov'it 6-piston 342mm looks like (test fitting it). Should stop very well...
But pricing is
3.200,- € for the fronts only...
@bluewasp
Are your rear calipers the billet ones? 4-piston, right? Do you have a pricture where I can better see the rear calipers? And what's the size of your rear brake discs? I want to upgrade my rear soon, too!

Wilwood factory front kits for the C4 are not available in the 14.25" W6a application but I'd be happy to look into producing one for you. Figure you're looking at about $2200 plus options.

I can't imagine that being a direct bolt-on kit...

The issue you'll run into with a lot of these will be based on caliper body overhang. Meaning the amount of caliper sitting proud of the wheel mount surface.
In the case of the Wilwood factory kit this is held to a minimum by way of both a 1.10" wide rotor and a narrow body six pot caliper. Still...that nets a required clearance of .790" as shown on page 3 of the pdf: http://www.wilwood.com/PDF/ds538.pdf
When you move to something both wider in rotor and larger in caliper this space needed will be even greater. Even going to a 1.25" rotor would increase this to .940". And when you incorporate a huge caliper body such as some of the above parts this grows yet again. In the case of a 1.25 rotor with the shown W6a caliper the net required space is now 1.21" behind the spoke. Can't say it can't be done but now you're getting into some funky shaped wheels (mainly racing) that have a large "coned middle" and very outwardly curved spokes.
My best advise is that before you purchase your wheels that you look at the options for it with brakes and keep those requirements in mind when shopping the wheel. Most wheel houses should be able to help you with this basic information and not lead you to a need for giant wheel spacers.

LT4Power: I'm quite sure the front Extreme Plus is a bolt on. The rear I never inquired. I quite sure you would loose the parking brake. I don't think any rear brake upgrade preserves the parking brake...have to maintain the original caliper for just that purpose or add a second mini caliper (like Movit pictured) for that purpose.
I've reread you are looking for bling bling so the Baer 6 piston that fits on the OEM rotor (for ~$1200) seems to be a great option.
