Good morning everyone, I was doing a tech inspection this weekend and found both my front wheel bearings were loose! The driver’s side was loose enough for the wheel to wiggle a bit. These were brand new Ford racing wheel bearings with extended studs and new Ford nuts. Installed in April of...

In case anyone is wondering when OEM sparkplugs actually wear out, its sometime before 900 autocross runs and 40k miles. My powertrain is 100% stock. Around autocross run ~880, the motor was breaking up real bad and down on power after the first runs of each session. I threw in new OEM plugs...

Hi everyone, Since day 1, 150 ft*lb felt bad and I reduced to 140 ft*lb when attaching my wheels. 40k miles, lots of motorsports, and many tire changes later a stud broke on the only wheel bearing I haven’t had to replace. I guess I’ll go for 130 ft*lb now and hope for the best...

Hi Everyone, I'm having trouble figuring out what the "right" part number is for the driver's rear GT350R spring. It seems that 6 valid numbers exist, but none are clearly confirmed in the Ford part descriptions: FR3Z-5560-S Now: FR3Z-5560-Y FR3z-5560-P Now: FR3Z-5560-W FR3Z-5560-T...

I autocross a 2018 Mustang GT in SCCA F Street Class. Car is stock except for shocks/struts, tires, alignment and a rear sway bar. Today while taking a right hand turn I lost oil pressure long enough for the car to go into limp mode. Here is the video where I lose oil pressure around the 46...

Last year I replaced the driver’s side rear wheel bearing because the wheel was loose. At that time I noticed the axle nut was loose on disassembly. Today it happened again. I decided to just tighten it back up with red threadlock and it seems to be fine again. I think launching the car is...

As several of you have probably noticed, the schroth quick fit doesn’t fit a 2018+ without some extra work and neither does a CGlock. I found that two of these seat belt tensioners from Amazon do a fine job and are ezpz to adjust. Just pull up on the chest strap, slide them down to the buckles...
