[Nicks67GTO]

If you've been keeping up with my thread you'll notice this is the second big brake kit Iv'e gotten for the GTO. I sold the TRSD kit to a fellow PY guy and moved on the these. I think the TRSD kit would have worked well and it was very nice but after some conversations with Tobin and others, I decided this was the right move to make.


Some more brake parts show up the last few days. My front brakes are partially from Kore3.com. I'm sure iv'e said it before but Tobin @ Kore3 is awesome. The guy is a wealth of knowledge, promptly answered every email I sent and at this stage of the game i'm willing to pay a little more for knowledge and top shelf customer service. Its worth every penny.

-So the front brakes are basically 2012 Corvette C6-Z51. The Z51 rotors are a 13.4" diameter and 32mm thick and a step up from the standard 12.7" C6 rotor for just a little more money. I opted for Stoptech slotted rotors. I found that they sell matching LS1 rears and Z51 fronts. This was hard to find. Since Tobin doesn't sell these I google shopped them and then beat Summit racing up on the price like I always do. They price matched and shipped free staying good to their word...and I really beat them up on these.

There are a couple reasons these are hard to match front and rear. First the Z51 is a totally different rotor than the stock C6. Also while the LS1 rear calipers are the same thing as C5/6 and the LS1 rotors have the same dimensions as C5, the LS1 rear e-brake setup is a bit different, so C5 rotors wont work. I also decided to steer away from drilled rotors. According to everyone that's ever tracked a car, a drilled rotor is prone to cracking under lots of stress and are really just a bling thing. Slots are functional and remove gasses.

-The brackets are Tobin's standard C5/C6 bracket.

-The calipers are big ol' twin 40.5mm piston aluminum C6. Though similar in appearance, the C6 are more rigid than the C5. The abutments are Z51 and allow for the extra rotor area.

-I also got Tobins flexcore stainless flex lines for the whole car. They appear to be top notch and the C5/C6 rear lines they sell will work with the LS1 calipers since they are basically the same thing.

-Since I intend to go to the AFX aluminum spindle/hub eventually I didn't want to spend the $300 bucks on Tobin's sweet ass aluminum hubs. I found out that stock drum brake hubs will work as long as they are under 5.95" in diameter. most stockers will need to be turned down though. I bought some brand new ones from CPP for $55 bucks with bearings, caps and hardware. I was pleased to find that they were already at 5.95" in diameter!! After sticking in some American bearings, longer wheel studs and painting them....ill probably have $100 total, saving $200 bucks tward the AFX spindles/hubs/arms later on.

-Brake pads are Hawk HPS {High Performance Street} Recommended by Tobin.

Here's some pics!...










CPP hub fits like a glove!!
