Because of the solid rear axle, the same rear brakes came on everything. There are subtleties in how the mechanical parts fit together because of the special setups like the larger rear discs on the 13/14 GT500, but the pads are the same. Even the factory race cars like the FR500S had the same...

There is a stock outline Mustang rear pad in Pagid RS56 compound available from a variety of vendors. It's a great compound. Northstar Motorsports has them in their online catalog. http://www.pagidracing.com/index.php?id=632&searchtype=v&cHash=5048da1df64d29f3fc6004e1260b6589&padref=8113

I actually don't remember where I found out originally, but my car came with a set and I eventually convinced myself that the measurements were correct. Here's a website with corroborating data: http://www.racingbrake.com/Shelby-GT500-Front-6-Piston-Caliper-p/bf-61bs.htm

The 2013/14 GT500 brake calipers have 30/34/38 piston sizes. If the 2015 OEM ones are 33mm x 3, then they have about 10% less total piston area than the 2013/14 calipers. If you're putting them on an S197, they should work fine, particularly if you're using the OEM non-GT500 rear brakes...

I did datalogs on my supercharged 5.0 and the OEM paper filter delivered better airflow than the K&N. Having said that, the difference was so small that there was no way to know without the datalog - it was about a tenth of a percent at WOT at 6500RPM with a TVS blower on the engine pulling 50%...

Sadly, not correct. First, the brake pads. They are designed to fit the rotor and the caliper at the same time. The width of the swept face of the rotor ("depth") has to match the depth of the pad. If the rotor is narrower than the pad depth, the pad will bind against the center hat or it will...

You have to stay "like-with-like" so if you're going to run the 14" calipers, run the 14" rotors. You can't run the 13.2" rotors with the 14" Brembo calipers because the rotors are too thin and the pistons will pop out of the caliper when the pads wear down. To say nothing of the fact that the...

The front steering knuckle (the complex casting that all the tie rods and the strut are attached to) is the same for all the S197 cars, so all of the front brake calipers (OEM 13.2", OEM Brembo 14" and OEM Brembo 15") delivered since 2005 are mechanically interchangeable and will bolt up, so...

I have a dumb question: are you running through the bump stop range in a static cornering state after the suspension has taken its "set"? Or is it when you hit a bump - like a curb?

The pad part number is an axle set - four pads.

No - unfortunately, Ford part numbers are hard to come by without actually visiting a dealer. There's a short-form version of the number, but it's generic and the details are important.

I had a look at the Ford parts site and the kit of anti-rattle spring, pins and the bolt is priced at about $30, so online you'll probably pay a bit less. That's not bad - if you were buying them from Brembo directly they'd be a lot more expensive. Here's some information about the...

1) Centric makes pads that fit these calipers - do a search and you'll find them. They're street pads only, but they're cheaper than stock by quite a piece - I think they're about $100 for an axle-set, which is four pads. 2) Personally, I'd just go to a Ford parts counter and buy a set of the...

The McLaren MP4-12C road car doesn't have sway bars and it handles pretty well.

I agree with the point about using Lambda - the Coyote ECU comes with wideband O2 sensors and all of it's mixture setting tables and parameters (like cat protection) are in Lambda, not AFR. Once you get used to using Lambda, everything gets easier - if you define a new AFR as Lambda = 1.0, then...

All a tender spring does is take up space when the suspension is at full droop. Once the suspension is loaded it goes into full bind, becoming a steel cylinder about an inch long. If you remove the tender spring you have to move the lower perch up in order to keep the same ride height, but that...

Calculating MAP, of course! Basically, if you want to pull X pounds per minute through a throttle at Y angle you have to create Z vacuum to do it. There are actually two tables - one that gives you MAF from angle and vacuum, and the inverse that gives you vacuum from MAF and angle. These tables...

It's all speed density all the time. Even idling. That means that while it uses the digital MAF for everything, there are no tables that link MAF and fuel. It calculates fuel by looking at the engine's ability to remove air from the manifold based on the estimated MAP, VCT settings, RPM...

Except that the Copperhead doesn't work that way. There is only one fueling variable - lambda - fuel delivery is calculated based on estimated airflow and volumetric efficiency. None of the old tables have carried across to the new system.

I think switching tuners will be a big help.

The Driver Commanded Torque table converts the pedal position into a specific torque level at a specific RPM. Sometimes as RPM goes up, the table calls for more torque at the same pedal position and sometimes it calls for less. This shapes the feeling of how the car is accelerating - many tuners...

Has your tuner ever set up a Coyote before? Some of the things you're saying don't make sense, for instance "Short Term Fuel Trims" don't tell you anything on a Coyote - the Long Term Fuel Trim takes over fairly quickly and the short term ones settle to a comfortable life around zero even if...

If you're asking about the 2011-2014 GT Brembo package 19x9" rims, FRPP's website says they won't fit over the 15" Brembo brakes. They barely clear the 14" Brembo front brakes, so it's not a surprise they wouldn't clear the 15's.

I don't know the calculation itself - that probably comes from Bosch; they provide the ECU technology, as I understand it. When I did all my track-day datalogging on my 5.0 I just tracked CHT and coolant temp. My pillar mounted oil temp gauge never went high enough to concern me.

There is no PID (OBD code) for oil temp in a Coyote ECU. There is an internal calculation of oil temperature that the ECU does for its own use, like the valve timing management. The dashboard display in the track apps uses this internal calculation.
