Very interested... would like the calipers to accept PMU pads. Prefer Option A followed closely by Option B. Would buy asap

With option B, would the 11mm increase in diameter have much better braking power? Or is it mainly help to with temp stability?

Typically, bias stays the same as stock... Or very close. There's a reason for that, though there are setups that need a change (big aero, maybe).

If you need more stopping power, look at changing the pads you run.

So it's more for temp stability/capability?

I've got to ask, why wouldn't you market the more capable parts as the top of the product line? Or possibly make two sets of brackets and market two kits with the same caliper? Again, I've got no dog in this race, just trying to understand the reasoning.

We currently do make two kits that use the same caliper (Sprint and Endurance), and the more capable one (Endurance) is the top of the product line in terms of how much abuse it can take. The situation now is a bit different however. We're launching a product into a mature market, and the Radi-CAL caliper is considerably more expensive than the CP8350. A) We need to know what people are after now, and if those wants/needs are the same as they were in 2012. B) We need to keep the cost appropriate for the market. C) We don't intend to kill off the current kits, so we need to find the best spot to slot in the new kit.

If we make the new kit the biggest, baddest kit available, with the largest disc, the most trick bracket, and the Radi-CAL, the price is going to skyrocket. The end result would potentially be more than many of our customers need or want, which is what I think we're seeing in this thread. The ultimate goal is to produce a kit that our potential customers really want, that is also actually attainable. I know a lot of people who really want a Ferrari 458 (including myself), but that hasn't worked out too well for most of us. :p

This situation sort of reminds me of Apple iPhone SE. For a while Apple was selling the SE alongside some of the older, larger models that had less advanced tech. It hasn't typically been the most expensive or biggest model, but for many customers it is the most desirable because it is the only one small enough to fit in a front pocket without making one look semi-excited.

We are customer-driven company. Our goal is to create solutions that our customers want. We start there, then see what is technically feasible, what compromises need to be made, etc.

Big brake kits are at their root about all heat capacity
, not 'braking power,' stopping distances, etc. Having ample heat capacity allows the car to be run for greater lengths of time on track without fear of pad or fluid fade, degradation of pedal feel, or component failure. Ultimately that means increased consistency, driver confidence, and lower lap times.

All of the AP Racing calipers we include in our kits use common pad shapes that have been around for a very long time. Just about all major pad manufacturers make these shapes, so I'd imagine you can get PMU pads in the proper shape. I tried to check their site online, but they doin't exactly make it easy! Your best bet is to check directly with PMU, or with whomever typically sells them to you. For cross-reference, here are the part numbers for this shape from some other suppliers:

AP Racing CP3215D42
Ferodo FRP3018
Carbotech CTP7445
CL Brakes 5004W42T17
Hawk HB718.654
Mintex 1970 16.75
Pagid 2126
PFC 7768.XX.16

Is the Raybestos R767 pad shape the correct one for the this caliper? As far as you can tell?

Also, what is your best guess of the time frame for release? One month, two, six?

Option B sounds fantastic. Subbed for further news on this kit!

The pad in that link is the same basic shape, but you would need the D42 (42mm tall) version of it. The one in the pic is taller than that....looks like the friction puck is the D50 (50mm) version. Can you please check with Porterfield if Raybestos makes that shape in the shorter D42 version? If they do, please share the part number. Thanks!

I honestly can't give any firm timeline right now. We are buried with a ton of projects and emergencies for race teams. It will definitely be several months at the soonest, and we still aren't even sure what is technically possible. The purpose of this thread was primarily to gauge interest and give some direction to our design based on what people want. I'll try to nail down engineering by 2/24/17 on what is technically feasible, and take it from there.

Thanks for your patience gents, and thanks again for the input.
