Engine wise look to Lindsey for waste gate upgrade, 3 bar fuel regulator, either a boost enhancer or boost controller, 3" exhaust and get it dyno with the chips remaped. It will be a much better car with less lag around town and at the track. As far as the power steering resevoir and tubing parts that can be fixed. Also don't use any rotors other than stock 9sun set porsche in OR) or Brembo cross drilled ($$$$$) which you will not probably require.

Z-man,
I simply stated another rotor option for Mark. Braking task is relative to the liter/older 911's. The case being if he wants the trick look and feels he needs the benefits of cross drilled, the Brembo are manufactured with the holes during the casting process and not drilled after, which would weaken the metal. When I replaced my front rotors I went with the original Porsche part. And yes I have the big blacks ( Many tuner cars love the cross drilled and are unaware of the failure of the non-brembo's.) I agree with you that the stock rotors would be the best option for the track.

Mark (Kool),
Have you been to DE events before or will this be your first? If this is your first, realistically, you only need to make sure that you have plenty of brake pad and that your brake fluid is good to go (change brake fluid or if a fairly recent flush, re-bleed the brakes).
Most of the track time in beginner sessions is focused on smooth driver inputs and learning the smooth lines. If you have natural skills or AX experience, you will progress quickly. In beginner run groups, you will definitely encounter some traffic which will prevent you from taking every lap completely hot. While a bit annoying, this actually saves your car from excessive tire and brake wear. A bit of a silver lining, I suppose. In spite of green group traffic issues, it is still a LOT OF FUN!
If you have been to the track a bunch of times, disregard the above and listen to the experienced masters here.

This will be my first DE. I have run autox's in the past. Although my skill level is up for debate. Curly DE and I have ran a couple AutoX's sharing cars and we usually end up having pretty close times. He is usually faster.
I got an email today from the PCA Registrar and I am in the DE. Adam did you have anything to do with that?

Take care.

Mark / Kool:
With your AX background, you already have an edge as far as learning to drive on the big track goes. (A top-notch instructor in my region can immediately tell if his student has AX experience or not - he prefers those who have dodged cones prior to venturing out on the big tracks!)
I am sure you will have a blast! Be sure to report back to us how you did!
Just a warning - as fun and addictive autocross is, DE is 10 times more addictive! You have been warned.

COngrats. A/X is good experience, especially in understanding the limits of the car...but Track driving is a totally different style and requires much more smoothness than A/X, I'm sure your instructor will beat this into your head all weekend... but I always tell my students that if you can feel when somebody started or stopped using any control (steering, brakes, throttle or shift), it is not smooth enough.
It should all blend together seamlessly.... concentrate on that and you will be miles ahead of the average novice

Cool
I hope so. Time will tell.
I am really stoked about going. AutoX is fun but it goes by so quick that you have little time to get a rhythm for the course. Unless you do a 24 autox.
I suppose that racing on a big track has a lot to do with rhythm and knowing what your car is going to do before it does it.
I can't wait to get out there.

Most autocrossers seem to adapt to the track very well. Hard braking, balance, corner speed, exit speed... all universal skills. If you're like me, you'll wonder why you ever sat in line for a short run when you can go lap after lap over the course in a nice long session.
Your face will likely hurt from grinning all day. Don't be alarmed, this is perfectly normal.
Have fun!

i guess the real difference is competition, as there is none in DE. so for those that like competition, autox is a way to meet that need.

In addition to about a million times more seat time, driving the exact same track over and over allows you to really grow and develop as a driver..."mastering" a given track or tracks becomes the quest of a lifetime...

Why just the other night I ran a 787B straight into a wall in Hong Kong.
Oh and for the record the ROI in an autox was not all that great for me. $25 for three runs. :|
I usually leave autox's wanting more.
