I just bought an S197 brake booster and disassembled it to see if it was possible to replace rubber with delrin. I removed valve assembly and found there is NO rubber between the fork rod and the MC push rod. there is a floating piston swaged to the end of the fork rod that can swivel but has no...

I'm not sure this is correct. I've bled the system and have a rock solid pedal when applying the brakes after purging the booster vacuum. With a solid pedal the MC has displaced all the brake fluid needed to move the brake pistons against the rotors. Brake fluid is incompressible, well nearly...

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...

Ford lied when it says you can turn off traction control. It is ALWAYS on in background and turns on when vehicle is outside of trigger point dynamics, like at the track. I fixed problem for track. see attached link...

I am running 19x10 Apex EC-7 rims because I have Brembo 6 piston calipers where there are only a few sets of wheels that will fit over the Brembos.

First things first. Traction control is NEVER fully off on the Mustang regardless of whether you've turned it off or not. Secondly, stability control function applies brakes to control car direction. If accelerometers sense yaw movement beyond their programmed limits they will apply appropriate...

I just spent 2 years building my 2011 GT into a track day car. I learned a lot of lessons along the way. Your BMR rear set up is fine. I went with Ford "K" springs which lowered the car 1.5" all around in combination with Koni sport shocks. Because car is lowered I went with Steeda front lower...

I've looked into Nitrous also. Main problem with it is that unlike carburated engines the Mustang intake manifolds are designed to move air, not an air gas/nitrous mixture. Using a throttle body plate configuration the gas/Nitrous mixture has the potential to form droplets and fall out of...

From my past experience, don't use speed bleeders. When opened to bleed brake line they let air into fluid so you will see air bubbles in line. You'll waste a lot fluid waiting for clean flow. Best bet is to use pressure bleeder. Works much better and you don't need a 2nd person pushing down...

I found problem and solution. 1) Traction control is never turned off. It operates in background and activates when certain criteria (?) are met. Ford lied in owners manual when it says Traction Control can be turned off. It's never fully off. That's why Boss 302R and S models have a different...

My one experience with an Exedy stage 1 clutch on my stock 2011 stock GT Coyote. It blew up first time I downshifted from high rpm and put a piece of shrapnel through my bell housing. Exedy told me to stuff it when I complained. Buy from them at your own risk.

I'm also an old time racer. Been doing it for 60 years. I learned to drive on track in cars without ABS. My first ABS car was an 86 Corvette and I hated the ABS. If you stood on the brakes like you used to on cars without ABS the ABS would kick in and you would overshoot your apex point. It took...

I've used butt connectors on most circuits on my cars. When properly crimped and insulated they work as well as soldered joints. You're more likely to have a problem with a cold solder joint then a properly installed crimp joint.

Good point but my incident occurred driving in a straight line rolling into the throttle. No braking.

I beg to differ. When you lower car LCA inner pivot is below ball joint. As suspension compresses arc of ball joint travel will add positive camber
