ZZP Big Brake Kit... is it worth it to DIY?

[mcanderson0]

The ZZP Big Brake Kit… they say 12" but its more like 11.81". That's important if you plan on upgrading from this point, but thats information for a future post.

Front rotors are originally from a 2010 HHR SS Non-Brembo, but ZZP chose a slightly different rotor design from Rock Auto that has some different dimensions and increased thickness. Then they custom drill the rotors for the Sonic’s 5 x 105 bolt pattern.

Here is the product page for the 'Left' (driver side) rotor:

…And then they are custom drilled. Apparently this rotor is direct OE fit for the 2005 Ford Thunderbird, Jaguar S-Type, and Lincoln LS. Interesting how they got there from the HHR.

Here's the product page for the driver side caliper (GM 18023839):

ZZP Kit: $399.99
DIY: $60 (x2) + $68 (x2) + $33 = $289… plus tax and custom drilling. So, not a bad deal actually to just snag the ZZP. However, this kit used to be $499 a year or two ago. This current pricing makes it worth it unless you know a guy that can accurately drill the rotors.

I'm piecing together a Wilwood kit based around the 300mm rotor diameter (I think they already have one based on the stock diameter). I'll definitely do a post on that due to the significant weight savings.

300 mm =11.811 inches

Indeed, what do you mean by that though?

I think ZZP chose the HHR equipment to design around, and then sought another 300mm rotor for better performance and landed on the Rock Auto special that was ultimately chosen.

EDIT: Stock rotor diameter is 276mm, btw

Let's just say that I am dumb, wouldn't we also need caliper brackets that would accommodate the larger rotors? Where would be a good place to find them on the cheap?

If you want to imitate the big brake kit, a '14 buick encore brake rotor (300mm and thicker than stock) with a 2002 camaro ss caliper and pads works great. don't remember how much altogether, I wanna say 200, and there's no modding needed it fits on quite well. I've heard this is what ZZP uses for their big brake kit (the smaller one, not the like 12.6 setup)
