View Full Version : (2009) Want To Autocross In A Z4

07-19-2009, 08:54 PM
This could be a silly question. In the past the answer was NO, but I though I would ask anyway. Can I autocross a stock 04 Z4?

It says a Z4 would be in Group 2. :)

Really!!!! I gave up looking a few years ago because convertables weren't allowed, IIRC. Awesome!

You were looking at driver's schools regulations.

Come on out. If in the right hands, they are one of the quickest BMWs in which to autocross.

Aghhh, I feel foolish now. For 6 years I've been thinking I couldn't race.... oh, silly me....

Nice! When you go look for a black Z4 driven by Noel like Car54 said above. He is a great driver and will be able to give you some good tips I am sure.

Will do, thanks!

These guys are a bit too flattering, but I'm not going to lie, it's nice too. Makes up for other areas.

Truth is: we have a lot of very good drivers here, but only two Z4 drivers. The other Z4 guy actually has a life and does not autocross like a zillion times per summer like me.

Anyway - You are going to love autocrossing that Z4. It's just great :)

I am always open to a ride along with me or riding with you too.

See ya then,

while noel is very modest ive driven his car and i cant replicate his times, hes a very smooth driver and always has clean lines, and is a pleasure to watch run the course.

and i believe all he has is tires [?] so you can get an idea of what a stock z4 is capable of

07-24-2009, 08:36 PM
Stop being so modest Noel lol.

To OP: the no convertible rule, as mentioned above, is for track driving... you can overcome that by having rollbars IIRC or cage I believe. miatas run all the time with those rollhoop thingees

I didn't want to cut up the car to install a roll bar, so years ago when I originally saw that rule, I ruled out racing the Z4. If I had only dug deeper...hmmm..... oh well... no sense dwelling on the past.

Funny thing was that I went to drag racing school instead.

Drag racing experience can be useful, many ax championships have been lost during the 1st 50 ft.! Its not called a hole shot for nothing. From an old dragger from the sixties. Bob

It was really interesting learning about proper throttle usage, burnouts, etc, and the actual theories and real world applications.

Will thick blue painters tape work for a number on the side of the car?

Anything else I should know ( no matter how small) ?

Blue tape should work fine :) Not sure if you have a blue Z4, but the color may be tough to read on the track when you're zooming by.

Pack at least the following:

Tarp/tent for stuff in your car, just in case it rains while your stuff is sitting outside. I like to remove all unnecessary stuff at home so that I don't have to put things outside and risk the elements.
Water and snacks so you don't dehydrate on hot days or go hungry since you'll be out there for a few hours.
Umbrella for rain.
A hat or sunglasses to combat the rays. I don't like to wear hats nor do sunglasses usually fit me, so I skip this one.
Suntan lotion.

If you venture into any tall grass, I also recommend checking your body for ticks once you get home, even if you're wearing pants and long sleeves. I was wearing pants at the last event at Summit Point and I found a tick near my knee when I got home.

I'm sure others can add more to the short list I have above.

What tires do you have?

Any modifications?

I'll bring a silver sharpie to mark your tires for rollover, to help determine a good pressure.

I have been running with 3 psi more in the front than rear: about 38 front and 35/34 rear when cold. They run well all day that way on shorter courses, but have needed less pressure after a few runs on longer courses on hot days.

My data is for Dunlops; you may need a psi more or two depending on what you have.

Believe it or not, the car is as it rolled off the assembly line, with the stock tires. The only thing not stock is a B&B muffler. Which really isn't a modification in my book.

The muffler puts you in Tuner 2 instead of Showroom 2.

07-27-2009, 03:16 PM
Wow, interesting a new muffler that does essentially nothing can move you in class. No biggie, I just really want to run more than anything else.

But it makes the rest of us envious because our cars are so damn quiet.

(you know, when I helped draft these rules they all made sense. In hindsight, some do seem rather harsh)
