Although we were not planning to eat Greg's '10 Camaro for dinner, it did feel a bit gluttonous to be tearing a set of practically brand-new Brembo four-piston calipers off of the Camaro to install an even bigger set of practically brand-new Brembo six-piston calipers in their place. I mean, what has the world come to when a factory GM car-a Camaro, no less-can ship from the factory with a set of front calipers that would have been fit for a professional race car just years ago, only to have enthusiasts wonder if they couldn't grab an even bigger set of front binders to install on their rides? For once we actually felt slightly silly for even thinking about modifying something on a perfectly good car, as we all know that the factory braking system on the new Camaro is great right out of the box. In a moment of self-doubt, it hit us-we're not crazy-the engineers at GM must have wanted this to happen all along! Take for example the new '12 ZL1 and the Cadillac CTS-V, if the engineering guys thought the six-piston calipers worked well enough to run on the two flagship sports sedans of the company, well then us mere mortals deserve the same stuff, right? The best part about the stolen-er, repurposed-Cadillac CTS-V brakes? They bolt directly to a fifth-generation Camaro without any modifications at all. That's right, they are literally plug-and-play, you just need to order the correct parts from the right vendor, wait a couple of days for everything to show up and bolt them on without any worry. If you're following along at home, you can find the entire parts list, complete with part numbers, in the captions that follow, but basically you will need everything that the Cadillac gets (front and rear calipers, pin kits, pad kits and all four rotors) minus new brake lines. If you're interested in converting only the fronts, that's okay too, since the rear CTS-V brakes are nearly identical to the stock fifth-gen stoppers except for the powdercoat (wrinkle-black vs. silver) and the pad compound. Along with the killer new brakes we acquired from Scoggin-Dickey Parts Center we also chose to order a new set of wheels and tires for the Camaro, hoping that wider aftermarket hoops covered in more rubber would not only help our Camaro stop and handle better, but look the part of a modified and personalized car instead of just a stock 2010 roaming the streets. For the wheels, we turned to Scarallo Motorsport Wheels and Group A Wheels, a company who has been producing excellent wheels for quite some time, but just recently entered the Camaro market place. Coming in hot with a set of 20x10-inch front wheels matched to a pair of wide 20x11-inch rears, the new Camaro specific Drift-R wheels looked all business and the curved five-spoke design was sure to frame up the new six-piston Brembo brakes nicely. Knowing that we wanted to run a wide tire combination, we jumped on the horn to Toyo Tires and ordered a set of the company's Proxes ST-II rubbers, which actually come out of their premium "SUV and Crossover" lineup. Go ahead and insert a joke about the Camaro's weight and size here, we don't mind! Truth be told, the ST-II line is actually fairly performance oriented and the 315/35/20 rear meats combined with the 275/40/20 fronts will not only make the Camaro look good, but they will keep the wheel speed sensors and ABS system happy, which is exactly what you want on a daily driver Camaro. As always, feel free to check out the install on the following pages as we document Greg Lovell's handy work on his fifth-gen Camaro project car.  1 The stock 20-inch wheel...  1 The stock 20-inch wheel and tire combo on our (okay, it’s Greg Lovell’s but we’re becoming attached to it!) ’10 Camaro SS performed well and looked great, but it was time for an upgrade and if we were going to install new wheels and tires, we also wanted to beef up the brakes.  2 Yes, that’s right, beef...  2 Yes, that’s right, beef up the factory brakes. Obviously, the four-piston Brembo units are stout and, truth be told, they are more than capable of handling all of the street and track duty we could throw at the Camaro. But, if the Cadillac CTS-V and new ZL1 Camaro can have the Brembo six-pistons, why can’t we?  3 Now we’re talking! Up top...  3 Now we’re talking! Up top is a factory four-piston Brembo from the 2010, below is a six-piston caliper unit that we received from Scoggin-Dickey Parts Center. Is bigger always better? That’s what we wanted to find out...  4a Looking inside the two...  4a Looking inside the two calipers, you can see that the CTS-V (left) has a much bigger piston to pad surface, along with the obvious addition of two extra pistons...  4b ...Otherwise, the two...  4b ...Otherwise, the two calipers are basically identical in regards to mounting points and component locations, which makes this a simple swap.  5 Comparing the brake pads,...  5 Comparing the brake pads, the advantages of the CTS-V caliper become even more obvious. Up top you can see the massive Cadillac pads, which dwarf the stock Camaro pads seen below.  6 Back to business, Greg...  6 Back to business, Greg Lovell of AntiVenom in Seffner, Florida wasted no time removing the factory brakes, starting first by getting the Camaro up in the air and pulling off the front wheels. A T30 Torx bit is used to remove the factory caliper retainer bolt, seen here.  7 Behind the stock brake...  7 Behind the stock brake caliper lie two 18mm bolts, which hold the caliper to the stock spindle. Before removing them all the way, make sure to remove the brake hose and catch the leaking brake fluid in something safe.  8 Swapping to the CTS-V brake...  8 Swapping to the CTS-V brake setup is basically a plug-and-play endeavor, but it wouldn’t be hot-rodding without having to modify at least one part. Highlighted in red you can see the area of the stock dust shield that needs to be modified (cut) to allow the CTS-V caliper to fit in place.  9 And that’s it folks. The...  9 And that’s it folks. The new 15-in. front brake rotor (PN 25851237) bolts in place of the old 14-in. Camaro unit and the new CTS-V front calipers (PN 25912477 and 2591296) slide right in place using the factory mounting hardware and lines.  10 Taking a peek behind the...  10 Taking a peek behind the front caliper, you can see how the factory brake line fits. Note, this isn’t the perfect solution; it would be much better to have a new brake line made to accommodate the lower (and longer) mounting position of the CTS-V caliper, but this will work while we wait for a new set of lines.  11 The new front pads (PN...  11 The new front pads (PN 25940447) slide in from the top for quick and easy brake pad changes should you need to perform them (at the track, for instance) and this makes installing them a breeze. Simply slide the new pads in...  12 ...and drop the pin kit...  12 ...and drop the pin kit in place. Of note, this pin kit doesn’t come with the calipers when you order them, so make sure you give Scoggin-Dickey Parts Center a call to order a set along with the rest of the parts needed for this swap.  13 Even though the rear brake...  13 Even though the rear brake calipers on the CTS-V, ZL1 and Brembo-equipped Camaro are technically the same, we chose to change them out as well, to keep the exterior appearance matching and to run the more aggressive CTS-V pads. Removal of the rear calipers mirrors the front, with two 18mm bolts holding the caliper in place.  14 The same T30 Torx bit...  14 The same T30 Torx bit will get the stock 14.4-in. rotors out of the way and the new 14.7-in. CTS-V rotors (PN 92245929) in place. Note the nice silver finish on the Cadillac rotors, a classy touch that really looked great on the Camaro.  15 Comparing the two calipers...  15 Comparing the two calipers may seem silly since they are basically identical, but the eagle eyed readers (that’s you) should notice that the crossover and bleeder screws are on different ends from one to another. This is due to different mounting locations on the cars (CTS-V mounts the calipers forward of the wheel, Camaro rear).  16 In stock form, the rear...  16 In stock form, the rear calipers will bolt on perfectly, but you can see that the crossover is positioned on the top of the Cadillac caliper, which would make bleeding the brakes practically impossible.  17 Fortunately, swapping...  17 Fortunately, swapping the crossover tube with the bleeders is a simple as unbolting them and flipping ends. Up top, the crossover removes with a 10mm wrench, while the bleeders take an 11mm wrench to break them loose.  18 Just like the fronts,...  18 Just like the fronts, the rear pads load in from the top of the caliper and the pin kit slides in place. We forgot to order a rear pin kit from Scoggin-Dickey Parts Center, but luckily the pin kit from the Camaro calipers worked, proving yet again that the calipers are virtual identical.  19 Though clearance wasn’t...  19 Though clearance wasn’t an issue [with the stock wheels], we couldn’t bring ourselves to install a set of killer big brakes without upgrading the wheels and these 20-inch Drift-R wheels from Group A Wheels made for the perfect crowning jewel. Built in a 20x11-inch configuration, the Drift-R’s allowed Greg to run a massive 315mm tire out back, get some much needed lip and show off those shiny CTS-V calipers.  20 Speaking of 315mm tires,...  20 Speaking of 315mm tires, check out the tread on these Toyo Proxes ST-II rear tires that we picked up directly from the folks at Toyo. Technically an “SUV” tire, these 28-inch tall monsters actually handle and perform decently on the Camaro and have tackled the road course and brake tests with ease.  21 Up front, the Group A...  21 Up front, the Group A Drift-R wheels look amazing hung over the CTS-V six-piston calipers and massive brake rotors. You can order these wheels in a variety of finishes to match your ride, but we’re loving the charcoal centers over the silver brakes and IOM fenders.  22 Not that we had any concerns,...  22 Not that we had any concerns, but it was great to see how much room the curved spokes of the aircraft T-6 spec aluminum Drift-R wheels left us around the CTS-V calipers. If you remember our install of these same calipers on a fourth-gen Camaro, you know how nice it is to have this kind of room around the caliper with an easy to find wheel and tire combination.  23 With everything properly...  23 With everything properly torqued and the brakes properly bled and burnished in, we hit up our private test track and tested our new braking ability, comparing the new CTS-V binders to the factory four-piston units using the new Toyo tires and Drift-R wheels for both.  24 “Wow, the pedal feel and...  24 “Wow, the pedal feel and threshold braking feels much better,” proclaimed Greg Lovell, owner of AntiVenom in Seffner, Florida. The improved feel wasn’t just in his head either as we recorded improved stopping distance to the tune of 4.32 feet on average (129.62 feet with the new wheels and tires vs. 125.25 feet with the CTS-V brakes). That improvement could mean the difference between avoiding an accident or causing one, or it could be the difference between diving in deep to a corner or staying behind the car in front.  25 On our test track at Gainesville...  25 On our test track at Gainesville Raceway, we had the chance to test new wheels and tires out, although we didn’t have the new CTS-V brakes installed in time to complete before and after testing. Either way, the new Group A wheels and Toyo tires chopped almost one full second (70.30 vs. 69.60 seconds) off of our lap times, a favorable result indeed.
