    Oops I thought I put in my bag, but it’s probably still in the trailer. We’ll find it 🙂

    Also Alexander Goncharov’s 40.xxx was a timer malfunction as well.

    Yeah 40.xxx is an error in the timer. Dave had the fastest time. Jeff had a 38.xxx in his runs, so similar error was happening all day.

    Also, Jennifer Houng final time seems wrong with a 47.xxx in the best column, but with no time listed in her seven runs (all averaging over 56).

    Thanks Brian for the quick turnaround!

    I have it Tim. I brought it home, I’ll bring it to next Autox or if I happen to see you before then.

    Autox Sept 6th

    These are my notes from Sept 6th Autocross course. Dave created an awesome course as usual! Some people did not need to lift after the U-turn going into the left sweeper at high speed, but I think it’s because they either had lots of grip or they did not do the U-turn well enough to have much speed on the straight. In my car, with older Direzzas, I felt the need to lift for a fraction of a second, turn left, then pour on the gas.

    Autocross Course August 2014

    Well, this was a TOUGH course! I think I had one or two decent lines on the hairpin, but messed it up most of the time. Even knowing the proper line didn’t help you EXECUTE it! If you messed it up, you paid for it in slower times!

    This map is what my specific car wanted to do, your mileage may vary depending on your car.

    Hi Henry,

    The best welder and subframe reinforcement guy I know is Tony Colicchio and his shop TC Design in Campbell. He’s always working on BMW’s among all other track cars. He is a welding expert and is very price reasonable.

    Thanks Brian! Also, there’s a guy with 0 points (car 171)…probably need to correct that.

    Yep, both of you are right, I don’t think anyone got that close to that corner, including myself. I just did the computerized line as the shortest possible route, but sometimes, it needs to be adjusted to maximize speed.

    July Autocross Course

    Continuing in the tradition from last month, here are my notes again. I ended up with a 42.0xx.

    Would love to hear feedback as I think I there was room for improvement in my times. I did not improve after my 4th run. I think this course was very technical and punished you heavily for over-driving, but overall very challenging!
