Derrick, Have run both directions at Chuckawalla--closest track to me--but no track times. My one moment of glory was passing a race-prepped Ferrari inside a turn (not a race-prepped driver). He was embarrassed. I apologized. Usually drive with their local track group. Small, plenty of...

OEM rotors are fine. Turned each year when pads are replaced.

Have been using Carbotech XP8s for track days; each set good for about a year with a full orchestra of screech music and nervous pedestrians on the street. Porterfield RS4s are excellent for street & autocross, but so quiet and clean. Have recently learned that the rear drums have a life...

Shortens the turning radius

Like my 949s

Derrick, Congratulations on two great wins at Fontana. Saw you on Saturday. Watched from all over the track. Enjoyed talking with you. You did great. Solved the mysteries of Fontana. Kept edging away from the Fits. Figured you would make it two on Sunday. Congratulations.

Derrick, Would like to stop by on Saturday to congratulate you on your victory.

What about Autopower??

Derrick, Isn't that an advantage to you if no one else shows up. But, won't last year's Fits' show. It's closer to their world. Don't know if you have run at Fontana, but top speed really helps. Some long straights.

Strip the car out; then add weight? Don't the rulemakers make a lot of sense. Could just add the safety equipment, and suspension changes & treat it like an old Showroom Stock. Drive it to the track and home again.

Left other message about pads. The CarboTechs I'm using are XP8s. Great on track, great on street, squeak on street, don't squeak on track. Not much dust. CarboTech warned about the street squeak. Choices: drive faster or provide warning to oncoming traffic.

First track day on car was Chuckawalla; original tires, brakes, pads; all good Second track-day & first day of 2 day program with AROSC on car was Streets of Willow, a shorter track & a very intense program; original tires, brakes, pads, all good Third track-day & second day of 2 day program...

Curious what tires you will be running at the Nationals? Are these treaded? Don't run slicks in T4/B-Spec do you? Same ones or replacements used during the season. What type of tire life expectancy do you have? (Hours? Minutes? Seconds?) And what tire pressures?

Using Direzza IIs, 205x50x15. For street use, 34lbs on all four; Haven't autoxed with these tires, will use 36 front, 40 rear. On track days, have been starting with 35 front, 32 rear. Check pressures before and after each session. At Buttonwillow & at Thunderhill this year found the after...

Spent two days there running counter-clockwise 13 on 4/6-7; Car (stock) did well, except a little weak on and off the front straight. You should have a lot of fun. It's a really good track. Would love to come out, but it's a little too far. Who's in your group? T3? T4; Do you know how many...

So many different ideas on tire pressures. Same front and back? More front? More back? After the usual rounds of mistakes, I use 36 front & 40 rear in autocross. Don't know if its good or bad, but it seems good. On the track, its 35 front, 32 rear. Last year was Dunlop Stars. This year will...

Wanted to stay legal if I decided to do H Stock. Found some D-Force 15x6 wheels (11.8 lbs) at Phil's Tires (advertises racer stuff); Needs hub centric rings for sizing & spacers 5mm) for front for clearance. Using with 195x50 new Dunlop Direzzas. Just on this week. Will try out next weekend...

With replacement wheels are any of you using hub centric rings--and/or spacers? How many inches or mm of spacers can be used safely for track or autocross use? Are you using longer studs? Wouldn't be fun to become a three or even two-wheeler.

Per Mazda, 15.75 lbs
