  1. Nitrogen was my first thought when you were talking about the race and the huge pressure swings. A small bottle is fairly inexpensive, like a small welding gas bottle would be enough for a few events, refills are stupid cheap after that ($25?)
  2. Makes sense to me. I would agree that the article is steered towards stock /budget limited classes on street tires.
  3. Agreed, I was just pointed to that link by a friend when I mentioned dropping front tire pressure to reduce push (understeer). We were having some fairly high temperature increases and were NOT rolling over the edge of the tire too much. (Re-71r on a Miata) Didn't make sense to me, and no one adjustment is a be-all end-all for any situation. Found out later that we were probably 5-7 psi above the recommended pressures for that car, which makes sense to me. I just wanted a reality check from some folks who've been there, done that (you guys) since I'm relatively new at this.
  4. Now, this may be my ignorance, but the tire rack article as presented below indicates that to decrease understeer one should INCREASE front tire pressure or decrease tear tire pressure... https://m.tirerack.com/tires/tiretech/techpage.jsp?techid=58 This seems backwards or incomplete to me. I see the tire similar to a spring where decreasing pressure adds grip (and heat) until the tire is overheating, rolling over too much, or in danger of debeading. I guess my gripe with the article is it doesn't specify where you started, but it still seems backwards to me. Am I just ignorant? Edit: there was a chart near the back of Caroll Smith's "Tune to Win" which listed a bunch of things that could be adjusted to change balance, I should go back and reference that to start.
  5. Decided to try the gas pedal extension with an angled part. Was at the junkyard for other reasons today and happened across a piece of 1/8 flat aluminum (it was a skid plate) which will work perfectly. See attached photo for current pedal position and with pedal depressed. Hard to tell the depth, and my foot is purposely off to the left to expose the brake pedal (before anyone asks).
  6. Hmm, I wonder how it would fit the XR pedal...
  7. I'll try to get some photos tonight, but the problem I was having is that the brake pedal is BELOW the gas pedal under hard braking. And the rest of the braking system has been gone through, reman MC, RBF600 fluid, stainless steel lines, and 2016 Focus calipers all around. Extending the width of the gas pedal couldn't hurt though. @Dennis where did you buy that piece you've got?
  8. This is what i was Imagining, but to the brake pedal. I like the bend/ angle of the gas pedal idea.
  9. There's a lot of other things for me to worry about before I get to setup on pedal heights, but I was curious what folks thoughts were in terms of the difference in height between the brake and gas pedal. It seems that my pedal has a ton of travel and, under hard braking, my foot is buried way below the gas pedal. I would have to lift my foot completely to get to the gas pedal. This makes heel-toe difficult. My thought was to put an extension on the brake pedal to raise the height a bit relative to the gas pedal. Has anyone else run into this and how did they deal with it or solve it?
  10. Fab work looks good! What are you going to use to paint it?
  11. Ended up bringing the Golf R daily rather than the XR4Ti (found some potential safety issues that needed to be addressed on the XR). Wholly heck the R is wayy too much car for my skills right now, but leaving the nannys on kept things under control. I didn't feel/ see traction control cutting in until the last session when it was hot, I was over-driving the car and I had roasted my tires. Had a great time, still much to learn. I ran racechrono on a 10Hz GPS antenna, but I haven't dug into the data yet..
  12. Are you using a 10 Hz GPS antenna with Harry's or just the internal GPS? 10Hz antenna makes ALL the difference. Garmin GLO (&GLO2), or Qstars (https://www.amazon.com/Qstarz-BT-Q818XT-Channel-Bluetooth-Receiver/dp/B003YCZINA/ref=sr_1_1?crid=FLPNBEND388U&keywords=qstarz+gps&qid=1559845782&s=gateway&sprefix=qstars%2Caps%2C151&sr=8-1) are cheap and work. I use a GLO2 with RaceChrono and it does a good job. Obviously AIM will be better, but for fairly little investment, this works.
  13. Driver has purchased another escort GT shell, (which already has a rally cage) and will rally on! Press on Regardless (POR)

    Then, that's shifter. That's like buying a ridiculously overpowered/ twitchy car to do your first track day. Edit: Also like buying a 1000CC sports bike just after getting your motorcycle license, you're sure go fast, but hard to learn anything of substance quickly.
  16. It was in the middle of a turn, and we had two more further up the road. It's a regulation to put the last triangle on the top of the car when you're not continuing 🙂
  17. x2, and the trifecta is after they're rubber wrapped, to zip tie them together so there's no movement.
  18. HA, I suppose that counts but that sure is different!
  19. It's always a lot of fun! Until it isn't. If it was my car, I may have tried to repair and start for the second day, but the windshield would have been hard to fix.
  20. Popped that cherry, had an unfortunate roll while navigating in the 2019 Dirtfish Olympus Rally. 26 events in before rolling, pretty good run! Roll cages are there for a reason, thank goodness for good safety gear, the driver and I were both totally uninjured. Car was mechanically fine, but needs a lot of bodywork...
  21. And if you're in DFW, check out GSPEED, on site at MSR Cresson.
  22. Thanks for the feedback. I think this first go round I'll sand the rotors and bed them on the track. I'll leave the track pads in and see how it goes on the street, it rarely sees street driving (mostly to/from track or autocross). If it's too squeaky/ too cold for the material, I'll get another set of rotors and swap both next time.
  23. Looking good! Good choice!
  24. I'm signed up for the June 4th event, glad to make it back to the track!
