E92 autoX success

I managed to score my 5th autoX class win out of 7 events in 2014 on Saturday, 7th fastest overall out of 66 drivers.

I was running stock power, stock sport suspension and wheels with daily driven Hankook RS3s (225/255). The E92 continues to impress!

Nice job! Can you tell/show me how/where you have that GoPro mounted?

AT? I have no autoX experience but I was worried that the fact I had an AT would basically disqualify my 335i from being a viable autoX car.

What other cars were in your class? Any tips for the AT?

I mount the GoPro upside down from the sunroof with the suction mount. If you just use the suction mount, the view out of the car will be obstructed by the rear view mirror. If you add a couple extender links, it hangs right at eye level and looks just about perfect.

I set the GoPro to record upside down and always use spot metering when filming inside the car looking out.

AT makes no difference. I just put it in DS mode during my runs with DSC off. The vast majority of autoX courses will allow you to stay in 2nd gear, but sometimes you may go into 3rd. Just use the paddles to make any shifts while on course. The rest comes with experience. I've been making steady improvements for quite a while by doing ~1 autoX/month with a track day sprinkled in every 3 to 4 months.

I've seen a wide variety of cars in my class depending on which group I run with, from E36 to E9x M3s, to 800+ hp track prepped Camaros and pretty much anything in between

Nice! I have that same/similar mount for my Sony Actioncam. I'll have to give it a shot.

Awesome! nice run! It's crazy that you are still pulling close to 1.2g's on stock suspension and stock camber.

I love the Roundel under the G-meter....what data acq. system is that?

It's an AiM SOLO GPS lap timer, and the overlay was done using DashWare. The car will typically hit around 1.1x max lateral Gs in the sharpest part of the turns according to the data

So im guessing the length of the car is not a problem ? I auto x'd my S2k and always thought the e92 was a little to long and heavy for the tight auto x courses.

Matter of prospective. Coming from an S2000, anything will feel long and heavy. I'm contemplating retiring my Z3 from full-time STR and am looking for an FS car. Until I find the right one, I'll give my 335i a whirl for an event or two to make sure I'm not going to drive myself nuts by getting into a car 700# heavier and much less prepped.

This is the only car I've ever autocrossed, so I can't really compare. I just try to adapt by driving patiently through the tight stuff and using the power when I can. I have several friends who autocross the S2k, and there's no doubt those are great cars

I used to watch your progress before I was banned on Bfc. Did you ever manage to put a set of headers on?
