I did a 1:59.108 in HP Autowerk's 335i on absolutely shot Yokohama AD08's. That car would be in the :57's with some good fresh street tires.

thanks J,

i watched your videos, nice driving! i'll try and get out there on a cool day with some decent rubber.

Keep in mind, those times are with pro-level drivers. I don't know where you are as a driver, but whether or not you can match those times is not important IMHO....The important thing is that you have fun, be safe, and keep improving your own abilities. You can't expect to just magically squeeze 4 more seconds out of the car in one day because someone told you it can do it. Gotta take baby steps!

i feel ya. i've been to two track days at BW on a streetbike and one in a car. all three times got bumped to the advanced group per instructor request. couple month ago i was .5 seconds off my instructor by the end of the day. that was driving his car too haha. if i can scrub a sub 2:12 in a stock i'd be happy with myself.

i also have a camaro mustang challenge car, it's a 94 mustang thats basically done up minus the engine and trans. just been putting money in other places than it at the moment. hoping to get it on the track by the end of the year.

cheers,

One day...I'll get my ass out to BW to see if I can achieve that. I've done a 2:06.x with my gutted Prelude on Toyo RA1's.

Hey Jeff, you didn't by chance own a black 135i with a cage and 2nd set of tires last august did you? I remember talking to someone at the track but I can't remember their name.

Jeff, I finally got my ass out to Buttonwillow. I kept your estimated lap times in mind all the time. Anyway, I did everything I could, but the quickest lap I did was 2:11.8xx. I think I can get to 2:10, or maybe 2:09 if the ambient temp wasn't in the mid-high 90s. I'll post up the video tonight or tomorrow.

Here's the best lap from yesterday. Jeff, feel free to critique my driving and/or racing line.

Ambient temp has a huge affect on lap time in stock street cars, especially big heavy turbo BMWs on runflats! After watching your video I think you can do 2:08 on a cool day and a tidy lap. A hot day vs cool day can be 2-3 seconds at that track in a 335i. (More like 1-2s in an S2000/Miata as they are much lighter and non-turbo).

Of course over all you are really really quick! And, there are always little things to talk about, but the biggest thing that stands out to me in the video is the corner entry technique for T1, T3, and the Sweeper. I think that if you blend your steering turn-in and your trail-braking (gradually easing off the brakes) together more, you will gain quite a bit of time in those 3 corners. So - rather than the relatively fast/abrupt/late steering turn-in, try turning in slower/less-abruptly; but sooner. Once you are getting close to the apex, then you add the heavy steering input. This whole concept relates directly to the 'traction circle' representation of a tire's grip ability.

You've seen my video from Buttonwillow.... Here is my friend Billy in a Merc C63. I think he illustrates the steering/braking idea I am talking about too. See what you think -

Thanks for the pointers, Jeff. Yes, I've seen your video multiple times, and I've seen Billy's videos (both the one in the C63 and in the FXMD NSX) too. I'll definitely try the trail-braking in those turns you mentioned, and I'll definitely go back in a cooler day.

My car wasn't 100% stock anymore. Well, it is bone stock in the power and suspension departments. But I was on square OEM 18x8.5 wheels with 255/35 Yokohama AD08s, and Carbotech XP12/XP10 racing brake pads.

Hope to see you on track some day.

Sorry to bring an old thread up. But I was just too excited that I had to share.

I did it, I finally did a 2:08 lap in my mostly stock E92 335i. The cooler ambient temp really helped as I didn't feel power loss at all, and I was able to put more laps continuously. Anyway, here's the video of my 2:08.55 lap from this past Friday.
