here are rotor specs and dimensions on the bracket i made
i purchased rotors as new old stock on fleebay
calipers are availbe from Summit Racing
i'm not sure how to post a pdf so jpg for the dwg?

Nice to see this coming up as that flood of Magnuson charger just hit garages all points everywhere!
Stopping better may be a conversation we hear alot in say 3-4 months, or a sudden bumper crop of "Parting my rolled 80" threads - all with a charger in the parts list!
Where did you source your rotors & hats?
What pads are you running?
Have you 'bedded in' yet enough to talk about 'nosedive' & if you think based on these sizes up front, that a bias valve might be seeing an install?

This is cool! I'd thought about modding my hub/spindle/rotor assemblies to use bigger GM rotors and calipers but never got further than the initial idea. Nice work!

Bigger tires have more mechanical advantage against the brakes. Adding winches, bumpers, rooftop tents etc require more braking power.

Yes, better braking is nice when running the SC
Calipers and misc. brake line fittings and fasteners are from Summit Racing.
Rotors are new old stock from ebay. For $100/ea. I could not pass it up J
Pads are Wilwood 7420 BP-20 compound. Specs are here Wilwood High Performance Disc Brakes - Brake Pad Compound: BP-20
Braking performance is awesome. I’ve been running the new setup for several weeks and absolutely love it!!! Initial bite, pedal feel, no-fade, good cold, good hot, etc… I’m a very happy customer.
When tire size is increased, braking performance decreases. So, I’m not really concerned about having too much braking, nose-dive, etc. I’m happy if I can get back stopping distances in stock configuration. I think I’ve achieved that and maybe more. Definitely a hat/rotor design with performance pads and performance calipers makes a huge improvement and bigger rotors account for the increase in tire size. I’ve been on one local trip and a lot of around town driving. My first big trip will be Moab in May. It’s highway driving that requires the brake upgrade, off road is not really an issue. So far I do not see the need for brake bias adjustment, but that may change with more driving.

I think there is money to be made for someone willing to produce and sell hats and caliper brackets.
Yep definitely is. It is not reasonable to do it one off for people. I am looking at over $500 to get the aluminum hats cut and spacers made. But if someone wanted to do a run of 15-20 pairs it would be pretty reasonable.

Somebody please create a group-buy, my brain is tired of trying to buffer braking distances behind vehicles ahead of me to compensate for increased stopping distance. I would buy if price terrestrial.
Thanks for sharing!

Why do you people temp me so!! Here I am thinking "cool, I'll go ahead and make myself a set" and now I need to pull it all together?!
I suppose I could

A setup like this...I would not hesitate!
Very impressed.
The GOV would disagree with you on that one.
One issue with a lot of performance calipers is they do not have a dust seal for the piston, they only have the fluid seal. This is ok for race cars that get the caliper torn down every couple events but for a DD vehicle, especially one designed to go off road this can lead to stuck pistons or worse failed fluid seals from excessive dirt getting into the piston bore area. The work that you did is great and I like the zerk fitting for the birfields but make sure you have dust seals for your calipers. The BMW race/fab & service shop I used to work at would only sell Brembo big brake kits for vehicles used on the street because Brembo calipers had dust seals. My friend looked into Willwood kits for his M3 because their pricing was better than the Brembo stuff but they did not offer anything for his car in their 4 or 6 piston calipers that had dust seals.
I have a pair of Brembo 17Z takeoffs from a Cayenne that are going to be going into my Audi.
They are a fairly easy to find/fairly inexpensive 6-piston fixed caliper. Typically will not fit under 16's however.

Good point. I will watch for fluid contamination due to dust/dirt.
My goal was to develop a functioning brake upgrade to address my poor braking performance.
If I need to rebuild/flush frequently I'm ok with that and appreciate you identifying the possibility.
This has been a long process and actually took a lot of time to establish fit and clearance while maintaining required strength and brake performance (hydraulics). There are not a lot of calipers that will fit/work. I was going to stick with the oem calipers but they will not fit a 14" rotor. So, I'm in for the long haul and will sort out any issues that come up.
But, for now I'm enjoying rock solid braking with 35" tires
