Soon enough.
When I'm sure another 30mm of rubber will fit under the front fenders.
I bet I won't even need to look out of the side windows to see where I'm going.

BTW nice runs, as usual.

I noticed you had a rather unique approach to it. You brake as you entered it, accelerated pretty hard, then braked again as you made the left. I am thinking the second brake was to shift the weight of the car forward to get more traction to the front tires? Really seems like you're getting the most out of the car, I told my friends there you were going to pull the best time

I meant to post this the other day, but with Brian's vid I look like I am driving a shopping cart with a wiggly wheel.

330 SMG Fastest run 10-22-6 - Google Video

Sorry for the pixelation...I tested the mount on a smoother surface...will be adding some insulation.

I want to lend Drew my camera...I need to see him going through the slalom!

To finish, starting at the 3rd to last cone in the slalom, which is the cone where the slalom began to open up, I was at full throttle. That caused me to carry too much speed into the offset gates. So, I braked to enter the offset gates, then got back on the throttle. I braked again to make the left and right through that sea of cones and got back on the throttle as I was turning right.

The part the impresses me the most about my run, and probably made the biggest difference in my times, was making that left/right so smooth and fast. It took a lot of steering input to get through there, and it was not easy. I imagine Andrew must do the same thing through the entire course.

330SMG- A few things I noticed about your run; you are turning too late and too much and you went through the turn around too wide. Turning earlier and turning less will allow you to carry more speed. Keeping a tighter line will allow to cover a shorter distance. The less distance you travel, the faster you will be.

My 53.635 run

Comments welcome. I understeered a bit too much at the turnaround and could have taken that smoother, and could have been probably faster in the initial few gates. This run was after hitting cones twice in a row, so I slowed it down a little and didnt hit any.

It looked like you turned a little late once or twice, and you took the slalom on the wrong side entering the turnaround. A little more air in the rear tires would help with the understeer.

Hopefully, I am not insulting anyone by trying to offer advice. I know I have upset someone by doing that recently.

I didnt feel like messing with my tire pressures much -- I was actually going to do just that and reduce pressure in my front tires too, but I just felt like running the car the way it was.

I actually preferred taking the slalom to the left as I ended up with fewer turns and the exit seemed easier to make, after watching people take it on the right repeatedly I felt the left was best for me. If I had more time I'd have tried it the other way around.

Thanks for checking the video and the advice =)

On all of the turns or just the turn around?

I am usually more patient...but it was hard to judge the turn around because of the slalom right before it. I also was late on the l box at the end, but that was out of fear of catching my right rear on the last cone. I was rushing through the course because I knew I was going to lose time to Russ in the box.

And djben...definetly take air out of the back. I had 48 hot upfront and 36 hot in the back and the car was very neutral.
