I'm glad you posted. I was thinking I had read about the frequent oil changes somewhere else. I forgot it was stated in the S650 manual. Running full synthetic I usually will go 3-4 track days before changing the oil. It just depends on the timing and how much time I spend on track each day...

For reference in case someone in the future is searching for the part numbers. Here they are : Front Subframe Bolts: W711810-S439 (Qty 4) Middle Subframe Bolts: W711805-S439 (Qty 4) Nut for Front/Middle Bolts: W707246-S440 (Qty 8) Rear Subframe Bolts/Washers: W717325-S439 (Qty 4) Somewhat...

I'm 99% sure I found the part. W707246-S440 This is the part number listed on the Dark Horse R parts documentation, and the K Member bolts match with the part number listed for the S650. Since the bolts are the same, I'm assuming the nuts will be as well.

Here's what I've found regarding fluids. Differential - Manual clearly states to change after 500 miles of track use. No question on that one. Engine - My oil life monitor will go from 100% to between 0-40% of oil life after one track weekend. Waiting for two track weekends is as far as I...

Does anyone know the Ford part number for the front subframe nuts? They are a single use part per the service manual, but I cannot find the part number or where to purchase replacements. @LevittownFordParts are you able to help?

FYI, the owner’s manual says to replace the differential fluid every 500 miles of track use.

No. The seals come out pretty easily and the new ones just press in.

When I started doing track events regularly and my wife saw me packing up so many tools from the shop into the trailer, then unloading them again when we got home, she said "You really just need to buy two of everything so you don't have to move them back and forth." That's a great idea, but...

Here you go. I added a new thread to keep it easier for people in the future who search for the guides. https://www.mustang7g.com/forums/threads/dark-horse-pp-brake-service-guides.177008/

Attached are the pages from the Ford service manual related to brake pad and caliper servicing on cars with the 6 piston front and 4 piston rear Brembos. I was about to post these in another thread in response to someone asking for them, but figured it was better to have a dedicated thread with...

Congratulations on finding a new (and expensive 😂) hobby. It sounds like you are picking it up quickly, and from my experience the more you do it the more fun it becomes. As someone who just started tracking in the last couple of years, I’ll share some thoughts from my relatively brief...

Tirerack.com shows the specs exactly as you have stated. I looked it up since it did sound very odd that a 305/30 would be taller than a 315/30 in the exact same tire. However, Tirerack also lists the 305/30 as 791 revolutions per mile with the 315/30 as 784. A taller tire will have fewer revs...

Is the benefit of upgrading from the one piece GT rotors simply going to be in the weight savings? Running the G-Loc R16/R12 on track simply for HPDE, not competition, is there any other reason to upgrade? I’m just wondering since a full set of OE one piece rotors is $500, it’s significantly...

@LevittownFordParts are you able to offer any discounts on the Ford Performance Road Race Oil Pan M-6675-M52RR and pickup M-6622-M50DRR for the Gen 4 Coyote? Thank you!

I don’t come off the throttle. I figure it is an AT, which would shift itself in auto mode while on the throttle; using the paddle shifters doesn’t change how it shifts, just when it shifts.

That aligns with what I have experienced and makes sense. I have not monitored the cutoff points that closely because I only hit it rarely and on accident, so I'm not staring at the rpm or gear to make a mental note. This is why I try to shift at 6500 so I can avoid the fuel cutoff. As long as...

I’ve only had mine overheat once and that was near the end of a 25 minute session. That was last November at Roebling when I was using auto mode. The weather was cool.

An interesting observation I have made is I see the highest transmission temperatures in cooler weather. I have no idea if that has something to do with the cooling fans or some other reason, but it’s what I’ve found. It was pretty warm on Saturday at Road Atlanta, and I didn’t see transmission...

Does anyone have what the max RPM is in each gear for an A10 before the car cuts fuel to the engine? I've researched online and see where there have been some statements that the 7500rpm redline is where it cuts in every gear except 6th, which has it cut fuel at 6800. However, I'm pretty sure...

Is there a way to copy the newer calibrations from the 2026 to an earlier model through Forscan, or is it only an option if you are tuning? I have one of the very early 2024 cars, and I've not noticed any significant issues on track, but just wondering.
