  1. S550 Lap Times (Road Course)

    Year/Make/Model/Trim: 2015 Mustang GT PP Track/Course: Road America Elkhart Lake WI Best Lap Time: 2:40:639 Tires (Size & Model): 285/35/19 Pilot Sport Cup2 A lot of traffic this day, but good drivers that let you by. I could have gotten into the 2:30s without traffic. Front straight mph...
  2. SPRING shootout --> FP-X vs FP-Y vs. BMR SP083 springs??? w/FP TRACK shock & strut kit?!??!

    Mine is a 2015 GT PP. It's good to drive when they are full soft. At full soft, my wife and I take it on long trips and it is comfortable. I think they would be on the stiff side, which is all a personal preference, if I didn't have the adjustable struts. It'll depend which struts you put on...
  3. SPRING shootout --> FP-X vs FP-Y vs. BMR SP083 springs??? w/FP TRACK shock & strut kit?!??!

    I have BMR SP083 springs, BMR Adjustable front and rear sway bars and Koni Yellow adjustable struts and shocks. I really like this set up for both track and street. i wanted the adjustable struts to dial it soft for the street. Its very reasonable to drive on the street at full soft. At full...

    All up to date! It's been a great season. Keep the track times coming! Fun to see some new tracks and people returning to the tracks.
  5. Mach 1 Oil Change - Filter put on Dry Per Ford Recommendation

    One time a looong time ago I didn't oil the gasket, the seal came out of its groove and bunched up. Felt odd, so I took it off and thought, "oh that's why." I've oiled it ever since with just a very light film.
  6. The Driveshaft Shop: Beware

    I have a $1000 paper weight in my shop that vibrates like hell above 45 mph. I bought it as part of a winter project, so by the time I figured it out I was over the 30 day return policy so American Muscle won't help. Tried to find a local shop to balance it. None can balance the CV style I joint.
  7. S550 Lap Times (Road Course)

    I agree, sometimes I wonder if something, like the Cup 2s, is a product really the best or just popular.
  8. S550 Lap Times (Road Course)

  10. Trailering a S550

    It's a split decision! :) I'm a little paranoid because one time I hauled a dune buggy with a Corvair engine and VW transaxle in gear and it bent the forks in the transmission and it never worked right after that. Still on the fence. 🤷‍♂️
  11. Trailering a S550

    For a manual transmission, do you haul with it in gear or neutral? If in gear do use the 1:1 gear? i.e. my MT-82 would be 5th gear.

  13. Tremec Magnum XL not a good choice for Raod Course for me

    I decided to take it to a local transmission shop. they put the Carbon Fiber synchros in it. Everything else was fine. I used the Center Force dual friction clutch and put a Motorcraft stock part number throw-out bearing in. I'm using Amzoil 75w-80 transaxle & transmission oil. I also took the...

    Updated. Thanks for letting me know. Sorry for the mistake.
  16. TR6060 Final drive Ratio

    I looked back at one of my posts and the math does work out. I thought my rpms were higher than 6800 at about 143 mph. Now I need a super charger to push up in to the 150s! 😀 I have my governor set at 7500 as well.
  17. Tremec Magnum XL not a good choice for Raod Course for me

    I just talked one of the guys at Calimer. He said 6th gear synchros going out is very common. That the factory synchros are weak and upgrading to the carbon fiber synchros will solve the problem. I'm going to ship it to Calimer. Thought about doing it myself, I've done transmissions before, but...
  18. TR6060 Final drive Ratio

    I would be surprised if you can get 143 mph @ 7500 with trans ratio of 1:1 and rear diff of 4.10. I have 3.73 and run 285/35/19 on the rear. In my 1:1 gear with 3.73, I'm maxing out at 143- 145 mph... I'd have to go back and look at some track day videos to be sure.
  19. Tremec Magnum XL not a good choice for Raod Course for me

    My 6th gear Syncrho is out of my MT-82. I looked at swapping in an XL, but decided the gearing isn't right for what I use it for, which is road course trackdays. I would be doing mostly 2nd to 3rd gear shifts. The 3160 would be a better option. But there doesn't appear to be to many of them...
