I finally got around installing the big brake conversions for the C3-R. I have 13" drilled and grooved rotors all around. 6-piston superlites in front, 4-piston dynalites at the back.
I finished installing the front ones tonight. Pretty pleased with the front kit, only thing that was wrong were the bolts attaching the hat to the rotor. With the washers in place (like said in the instructions, which BTW are a big joke), the bolt heads are 2mm too tall and they interfere with the wheels. I can't install the wheels in place before I find right set of bolts.
Second thing is the rear rotors. The rear hats are designed to work with stock drum parking brake set and the hats are great. BUT the rotors are all wrong. They came with the wrong bolt pattern for the hat. I contacted PBC right after I noticed they were wrong and so far their tech support has been NONE...
I also had pair of bumpsteer blocks fabricated, which I will install tomorrow and I need to adjust the steering a little bit.
Once I have the rear rotor issue sorted I will have the car aligned again, hopefully it will be before the summer is over again...
Thanks, I'm hoping to get some track time after I finish up the installation to see if these new brakes really can cope with some serious beating or will they just fade after few laps like the stock brakes did...
so you ordered the rotors/hats from precision brakes co??? I want to upgrade to a seperate rotor/hat combo in the future and if that stuff is bolt on then that'll be the way I'll go. I like the dark anodizing, I assume the hats and rotors are wilwoods also?

Both are PBC's own design, at least that's what they told me...
I won't mention the numerous problems I've had with this company. I will say however, that after about 1.5 years they finally straightened the last problem out.
The quality of parts is top notch. It will be a considerable effort but if you work at it long enough you'll have great brakes from this company.
One thing you'll have to do, Twin Turbo, is send in your hubs to be machined down a few thousandths around the outside and the edge will need to be smoothed off. Precision Brakes did this for me for free. I know others to have had this same problem. The hubs just won't fit in their hats.

That's too bad to hear other having the same problems. So far their tech support has been very poor, no one seems to know a thing and so far they haven't been too helpful.

I never got as far as tech support with Precision Brakes because their sales support was worse than poor. I ordered what seems to be similar to your package back in January and was told I'd have delivery in 2-3 weeks. After 4 weeks they gave me some bogus story but said I'd have everything 2 weeks later. After 6 weeks I really started screaming and a shipment arrived at my door at the middle of week 7. Ooops. Wrong rotors, no master cylinder, other missing parts. I shipped it all back to them and requested a refund. That took another 2 weeks after I disputed the charge with my credit card company. These guys don't seem overtly malicious, just really disorganized and I'd never do business with them again.

Now I'm starting to wonder how this company is still in the business. I went through exactly the same process with my order...
Those bolts look like cap screws. My son gave me what I believe is called button head, they are still capscrews but extremely low profile but still use an allen wrench. They might do the trick for you.

With the washers in place (like said in the instructions, which BTW are a big joke), the bolt heads are 2mm too tall and they interfere with the wheels. I can't install the wheels in place before I find right set of bolts.
I went looking for a picture of a button head cap screw and while looking suddenly wondered how even a normal cap screw could interfer with mounting a wheel??
This is my hat but most of the screws are missing. I increased the number of screws to about 20 since they looked so small and I believe they only use 8 normally or something like that.
My heads could be inches long and still clear the rims?? this is what is confusing me.

For sure keep us updated with how they went. I need to be getting some breaks...

those button head screws are tiny, good thing you have 20 of them.
The thread is the same as any cap screw. The small part is the heads are little round buttons. They still clamp as well as any cap screw.
My son just thought they would look good.
As for using 20 instead of just 8 I thought with my oversize hats 8 would look funny, 20 just worked out.
I ran oversize hats so I could get rid of more metal. Normal hats are what 8 inches maximum. I am running about 10 1/2. They still clear the calipers easily and it leaves that much less heavy metal.
This is a comparison between these new large rotors and a stock one. The large rotor with it's aluminum hat weights exactly the same as a stock rotor, not this stock rotor, it is 3 pounds underweight.
That stocker is at least 10 years old without a single crack from hole to hole.

Hi Norval, your front hats are attched same way as my rear hats. They have that lip. Here's a pic of my front hats and the bolt heads that stick out 1.5mm.
See how the bolts go all the way through the whole hat... Just 8 bolts are holding them in place front and rear.
