  • I have the set on the car and a spare set and there's no human-detectable play in any of the four. If the bearing separates under a high lateral g load, the only thing that can keep the wheel on is the brake caliper. (see full post)
  • Depending on your schedule, contact FP again and show them pictures of the play. They may have a defective batch.I had this problem once on a set of replacement OEM rear hubs (with longer studs installed) on my GT350 and it was caused by the... (see full post)
  • JAJ replied to the thread More awesome news out of DC.
    I've been watching this thread with interest. A few points from my decades of watching regulatory overreach develop and grow to fruition:1. That there's a car industry at all is an urban myth. It was completely destroyed back in the 1970's... (see full post)
  • JAJ replied to the thread coolers for road racing?.
    The 10 vs 12 issue goes back a long way, it might have been for the Boss 302 race cars running Coyote's. There was a post about engine problems by Kohr (or whatever the name was before it was changed to Kohr) and from that point on, -12AN has... (see full post)
  • It depends on your needs.Ford, bless their hearts, made doing what you want to do really easy. The front knuckle on the 2020 GT350R (NOT the 2020 GT350) is exactly the same as the GT500 front knuckle, except it's been machined for the GT350... (see full post)
  • JAJ replied to the thread IMSA penalties explained..
    This did create a real dilemma for IMSA and I think their decisions were about money. The teams running the unfair cars likely knew nothing of the unfair advantage - they "runned what they brung" and won the race. While it's great for the team... (see full post)
  • Exactly. The OP says he has a diff cooler so the spec lube that Ford puts in the high horsepower, high torque, cooler-equipped GT500 should work fine. (see full post)
  • JAJ replied to the thread Tire size for handling package.
    I went looking for a Trofeo RS review and didn't see any. Can you point me at one? I ran Trofeo R's in the past, I really liked them and they're what I'm switching back to when my current set of MPSC2's wears out. I saw the RS, but they're an... (see full post)
  • You might want to switch back to the diff oil the car came with. Ford runs 75w-85 diff oil in the FP Shelby's because it generates less heat under high load than heavier oils and it lubricates at least as well or better. It's a modern... (see full post)
  • JAJ replied to the thread Daytona 2024.
    Just imagine all the downforce you'd get if you ran a wing mount arm from the front bumper up over the roof! It'd be awesome! (see full post)
  • JAJ replied to the thread Daytona 2024.
    The force that affects the axle comes from the chassis. It doesn't matter how the wing is attached to the chassis, the location of the wing relative to the chassis and relative to the axle doesn't change from one bolting location to the other... (see full post)
  • JAJ replied to the thread Daytona 2024.
    Hmmm... I'm with AJ on this one. The wing's downforce acts at a distance behind and above (or below) the car's pitch center. The car's pitch center is like the car's roll center, except it's about fore-aft attitude (pitch) changes under... (see full post)
  • JAJ replied to the thread Minimum Oil Temperature?.
    There are three things that I've taken on board over the last 20 odd years of driving performance cars:1. The engine oil temperature that matters the most is the oil temperature in the bearings that are being lubricated. Since you can't... (see full post)
  • JAJ replied to the thread Minimum Oil Temperature?.
    Well, GT350 launch control is disabled unless the EOT is 170 degrees or higher. I'd start there... (see full post)
  • Getting a good mix involves some force when adding fuel. If you're able to put 2.5 gallons of X98 into the 5 gallon container and then top it off with the second 2.5 gallons from a gas-station style fuel pump nozzle, the force of the fuel coming... (see full post)
