I really don't remember what I for brakes lines with 6 piston Brembos. I think I just used the Goodrich lines I had on with the original Brembos.

I came to several conclusions after the booster tear down. 1) THERE IS NO RUBBER BETWEEN THE BRAKE FORK ROD AND THE MASTER CYLINDER ACTUATION ROD. The floating piston seats into the master cylinder actuation rod for a solid mechanical connection between the brake pedal and the MC. 2) there is...

The valve rod assembly in made in two parts, the fork shaft and a floating piston swaged to the end of the fork rod. The floating piston can swivel but it is seated firmly to the fork rod. The whole valve assembly is installed on the fork rod and the the floating piston is swaged to the fork rod...

I am trying to reduce brake pedal travel on my 2011 Mustang track day car after installing 6 piston "Bullitt" Brembo front calipers. During my search for solutions I came upon a post showing a .312" rubber washer in between the brake booster fork rod and the master cylinder actuation rod. The...

I found this bit of information on the Mustang Forum which I found most interesting as I think it addresses some of the brake travel issues I am trying to resolve.“There is also a rubber disk in between the booster diaphram/input rod and MC rod (output). I suspect Ford put it in for NVH, but...

I have a 2011 mustang GT that came with the 2 piston Brembo Performance Package front brakes. I've upgraded the brakes to the 15" front and 13.8" rotor GT500 set up using 2018 Bullitt 6 piston Brembo's up front. Due to the larger piston area of the 6 piston Brembo's I have a longer pedal travel...

Spoke to Tim at OP Mustang. He recommended G-LOC R-12's over R-16's or 18's. I'm running 300 tread wear rated 285/35/19 Michelin PS4's because I have to drive 100 miles to tracks in rainy Florida. Tim's thought was that R-16's or 18's with Brembo 6 piston caliper and 15" rotors could over power...

HELP!!! It's racing season here in Florida and I can't find the brake pads I normally use. My track day Mustang has 6 piston Brembo's up front with 15" dia. 2013/14 GT500 rotors. I usually use Hawk DTC 60 pads (P/N HB805G.615) in the Brembo's. I run Hawk DTC 30's on the rear. The combination...

I'm not an aerodynamicist but I am an engineer who has been building drag, autoX, road race and track day cars for over 60 years. One thing I've learned is that going faster is achieved by small incremental improvements in every aspect of the things that can make a car go faster. The air flow...

I installed these 2012 factory style hood vents on my 2011 S197 and they really helped. Biggest benefit was allowing air trapped under hood to be evacuated. Greatly reduced visible hood lift at speed. Interestingly the low pressure area on a Mustang hood is located right behind the radiator yet...

I have been working on cleaning up the air flow under my 2011 Mustang track day car. One thing I have been thinking about is adding vertical rubber side skirts between the front and rear wheel openings. I'm trying to keep the air flow under the car clean with minimum turbulence to get the...

I looked at their site. They only have a diffuser for an S550 and it looks more for decoration than for function.

No I didn't weigh it. Here is link to materialhttps://www.piedmontplastics.com/resources/literatures/piedmont-sign-gradeR-alupolyR.240" thick weighs 1.38 lbs/sq ft. If I had to guess I'd say whole assy weighed 12 lbs.

The diffuser is made of a composite, aluminum surfaces separated by abs plastic. It's pretty solidly constructed. I doubt if it will move at speed. CFD data would be nice but no small manufacturer can afford it. If they dis CFD price would be much higher. Sometimes you just have to go with your...

Whoops. What I meant to say was if the SPOILER was of any significant height.
