  1. 2025 GT engine oil temp runs hot

    I understand frustration at a car getting near limp mode temperatures, but I think you have to step back and look at it from a manufacturer/average buyer perspective. We have all sorts of threads with people complaining about the price of the S650, so pricing is obviously a concern for many. It...
  2. Fitment advice: GT with progressive springs, daily driver with a little road course time

    On a 20x9 wheel 285/35/20 could be mounted, but it would likely be wider than the recommended by the manufacturer for your wheel width. You also have to consider if it will fit in the wheel well without rubbing. The OE Ford wheel looks to be a 42.5 offset. Therefore the stock tire is...
  3. Fitment advice: GT with progressive springs, daily driver with a little road course time

    The need for a spacer is determined by the backspacing on the wheel as well at the tire width. When you buy a staggered setup designed for the S550/S650, the offset (and therefore backspacing) is set where the wheels fit inside the fender and don’t rub the shock or strut. If you put the same...
  4. Transmission Fluid Check How-To (Not Fun)

    I plan to drain and refill every other track weekend to coincide with the fluid change in the axle. Assuming a 13.5 total capacity (allowing for more than specified in the manual to account for the cooler), with a 9 quart drain and fill, that is exactly 2/3 of the total fluid drained each time...
  5. Transmission Fluid Check How-To (Not Fun)

    It shouldn't. If the amount drained was exactly the same as the amount filled (which would be nearly impossible to get exact), the dipstick should read identically before and after, regardless of whether fluid is retained in the torque converter or anywhere else. I did not check the fluid...
  6. Transmission Fluid Check How-To (Not Fun)

    The torque converter as well as the transmission cooler and lines retain fluid. Per the owners manual all variants have a 13.1 qt transmission fluid capacity, and per the repair manual all have a 13.0 qt capacity. However, I don't know how there couldn't be a difference for the the DH/PP...
  7. Transmission Fluid Check How-To (Not Fun)

    Based on my fill, I estimate it was just over one quart low from the factory. I filled it will nine quarts, but I only measured 7.5 quarts that I drained out. And yes, that picture was before I dropped the pan and it was completely dry under there with no sign of any leaks. However, I did...
  8. Transmission Fluid Check How-To (Not Fun)

    For anyone who has thought about checking the transmission fluid in their 10r80, I’ll let you know it is not fun. I changed out my transmission pan for one that has a plug so I can regularly change my fluid since I am tracking my car. I have the shop manual which says the initial fill after...
  9. Fitment advice: GT with progressive springs, daily driver with a little road course time

    If you are wanting to do a square setup with the Steeda springs and use it as a daily driver with the same tire and wheel setup that you use on the track, then I personally wouldn't go any wider than a 285 tire, which would work well on a 10" wide wheel. If you choose wheels that fit the rear...
  10. What did you do to your S650 Mustang today?? šŸ™‹šŸ»‍ā™‚ļø

    The main reason I installed was to have a drain plug for changing the fluid. I’m tracking the car, so I plan to change the fluid each time I change the axle oil, which is roughly every four track days or around 500-600 miles. As a secondary benefit, it is aluminum and has cooling fins, so it...
  11. What did you do to your S650 Mustang today?? šŸ™‹šŸ»‍ā™‚ļø

    Installed the PPE 10r80 transmission pan.
  12. Track Weekend at Barber MSP - 5/31/25

    I’m trailering. At this point the car is essentially track only from May though November.
  13. First mustang and it’s nothing but problems

    Same. Picked up my ā€˜24 on September 1, 2023. No issues at 10k including some hard track miles.
  14. First mustang and it’s nothing but problems

    That's terrible! I'd be looking at the lemon law to push Ford to buy it back once it meets the threshold. Fortunately I've not had any trouble with my 2024.
  15. S650 Brakes

    This is accurate. Braking at the threshold of locking the brakes or ABS kicking in will give a shorter stopping distance than just stomping them and relying on ABS or skidding. In everyday driving I would venture to say for 99% of people, having the bigger brakes wouldn’t make a difference in an...
  16. S650 Brakes

    The Dark Horse and GT PP have the same brakes. The only difference is the DH has two piece front rotors. The DH and GT PP rotors are the same size and interchangeable.
  17. Brake Fade

    Absolutely not normal. I’ve never experienced brake fade on the street or track in mine. Definitely get it in to the dealer to find out the issue.
  18. Did your know that the tire monitoring on Fords is NOT that accurate?

    I check my tires after every run on the track and have never had the tpms more than 1psi different than my gauge. The tolerance may be 3psi, but I’ve never seen that much difference.
