  1. Another brake rotor option

    You guys have excellent, high-quality products and I've purchased from you in the past. I'm of the opinion the more options there are the better, but realize, for whatever reason, for the Mustang, on the high-end, race-type brake rotors are limited. There are literally dozens of two piece...
  2. Another brake rotor option

    I've been running PFC brake rotors for more than 15 years, mostly on another car and then the past 5 years on my '21 Mustang. I got good life out of them but both the front and rears are due for replacement. Evidently, there's a long story about some of the struggles PFC has had and...
  3. Mach 1 as a dual purpose street-track car (DE)

    From my prior post, I can't get any rear rotors for the PFC hats that I have and it sounds like they are not likely to produce them again. Went searching for some options as I like the hat and spring retainer system, which has been reliable for me. I was directed to a company called...
  4. Mach 1 as a dual purpose street-track car (DE)

    Totally agree, the accuracy and precision of these alignment systems is probably greatly overstated. Probably yes, 0.1 degree plus-minus is the level of accuracy, NOT 0.01 degree which is absolutely tiny. Just got my replacement PFC rotors today, from Spain! No sets in the US, had to order...
  5. Track day tire decision

    There might be a driver style component to this factor. :) I've been though many sets of Cup2s and only once heat cycled a set out. The rest all wore out by showing cords and I run a pretty good track alignment. Maybe the Vitours will be just fine and if you've got the $$, give them a try...
  6. Mach 1 as a dual purpose street-track car (DE)

    Well, I measured my total toe, front and back with a set of toe plates I have. Remember, I wanted TOE out up front, what I got was 1/32" toe IN (wanted around 1/16" OUT). Not the end of the world but if you're "the alignment guy" and you need to keep my car "all day to get it right." Why can't...
  7. Track day tire decision

    I'm currently running Vitour P1 tires and have only one weekend on them. However, based on the wear pattern I'm seeing, I don't think they're going to be very durable and will probably show cords before they heat cycle out.
  8. Mach 1 as a dual purpose street-track car (DE)

    Thanks for the compliment. Back from alignment today. Lots of tire shops don't want to do non-stock spec alignments. Then booked with a local, private shop, and they were nice but said my car was too low and wouldn't make it up on their alignment rack, so recommended the Ford dealer and said...
  9. Clutch master cylinder replacement DIY

    Nicely done! Better than a service manual. Nice detail and explanation.
  10. Mach 1 as a dual purpose street-track car (DE)

    I've run Charlotte, it's fun, and even pre-KPM fuel module didn't have an trouble there. I would say the fuel starvation is really a complete engine cut for just a fraction of a second. Might have one or two of those in a row. It's not subtle at all and feels like it can't be good for the motor.
  11. Mach 1 as a dual purpose street-track car (DE)

    This was my subframe 2-3 weeks ago.
  12. Mach 1 as a dual purpose street-track car (DE)

    Dana Pants, I think the torque spec issue is a really good point. I have long standing habit of torquing and then paint marking my critical nuts and bolts. Just did that on all the big parts two weeks ago when I had the subframe out and bushing replacement. Still a good idea to check torque...
  13. Mach 1 as a dual purpose street-track car (DE)

    Aren't you an autocross guy? I used to autocross, it was a lot of fun, but unless things have changed in the past 20 years, it's completely different than running on a race track. The biggest stress and load to the car is running curbs, at speed. That's one of the primary ways that alignments...
  14. Mach 1 as a dual purpose street-track car (DE)

    I haven't updated this set of posts in quite some time. I still have the car and it's still great for my use. What's happened since 2024? Nothing bad, car is completely reliable, doesn't burn any oil even with track use. Some observations and updates. 1) Found out the "hard way" that the car...
  15. I notched the strut tower hole instead of using hole saw (many pics)

    Another vote for round-hole approach. It's probably less labor intensive than notching too.
  16. Diff bushing replacement, what's the secret?

    Road Report Back on the road and running. Only did 15 miles, all secondary roads, some bumpy, some smooth. First what the car is NOT. It's NOT more planted, more connected, more nimble, more responsive or anything that feels "better" with normal road use. This is exactly what I wanted, no real...
  17. Wrong tow hook !!!

    Are you sure? The tow hook is reverse thread, try screwing it in backwards, see if that works. Hope all is well.
  18. Diff bushing replacement, what's the secret?

    Now, that sounds painful. Hopefully, no injuries, but there's been plenty of time to heal!
  19. Diff bushing replacement, what's the secret?

    Feels like it's been a long haul. Car is driveable, if open headers were legal, so I'm staying in the garage for now. I'm going to weld my cats to my connecting pipes so there aren't so many clamp-type joints in that section. Turns out the other item that' was most challenging, in terms of...
  20. Diff bushing replacement, what's the secret?

    Going back together like a Lego set. Placed axles, with the outer carrier, torqued all the big boy bolts, refilled diff, installed shocks, reconnected the electrical connections. Now I'm in limbo for a bit. 1) I've run PCF V3 rotors in the past 2 cars for over 15 years. Prior ring replacements...
