I am trying not to change my exhaust. I guess I'll wait to see what happens to Steve's car. I would want to keep the kit on full time, not too interested in removing it unless it is absolutely necessary ... in which case it would not be practical. I am researching doing an APR wing/spoiler on the rear. Other than looking ridiculous on the street I think it would not affect driveability.

You could run this setup with your exhaust, you just won't have the adjustability of the rear diffuser.
Read everything that Brian has posted in the aero thread. Wings add alot of downforce, but a lot of drag as well. You can get a better balanced car with the aero package than just adding the wing. Brian has all the technical details as to why a wing is not the answer to going faster.
That being said, in order to get the proper airflow, you have to run a huge front splitter and side skirts to keep air from entering under the car. I don't think you'd be able to drive on the streets with it very long without smashing it.
Also, if you don't run a huge front splitter with the wing, you'll unbalance the car and put a ton of downforce on the rear only so you'll be understeering everywhere. I saw an ex-world challenge built e90 running a big wing without a front splitter. I ran past him very quickly. The next session he took off the wing and blew by me!

Hopefully in the near future, I can be an instructor at the events and have some fun with everyone.

Congrats, now give me your seats and brakes!

LOL! Brakes would be transferred to the race car if need be.

We bought a wrecked 2007 Z4 3.0si coupe yesterday via an online auction!
It has front end damage so I'm now trying to source used parts to save money. It only has 48K miles on it, so we'll see about what engine we use. We may switch to an M3 engine.
It's coming from California, so I won't see it for a week or so. Don't know much else about it yet.
Stay tuned for the full build.

Gang, what's a good time at Thunderbolt with T2 chicane? Say, equivalent to 1:20 at Lightning.

I'd say 1:36-1:38 with the chicane

If you blow through the chicane and go through the cones you get 1 sec back! They will blackflag you eventually :-)

Seriously though, that should be on par with a 1:20 pace at Lightning. Personally I find the chicane annoying because it's right after a turn and before a short straight, it's purpose is not to avoid crazy speeds down a long straight but I digress...

have fun!

1:20 on Lightning??? good god i'm far off from you guys .... my first time at a track and i'm at 2:20 lol!!! I wonder where i can loose a minute

So I'm currently looking at used X5's...

yeah buddy!!

Next step for Rob



Yes please

[StealYourFace]

TSM330- a Z4 with an M3 motor sounds serious! s65 or s54?

BTW, I am still trying to figure out if I want to go back to 3.64 or 3.38- with the 3.38s do you hit 5th gear at the Glen at all or are you able to keep it in 4th on straits? I have been playing around with a gear ratio calculator and am trying to figure out what will be the best compromise for a car that sees 20,000 miles a year and a hald dozen auto crosses and hopefully 4 track weekends.

I believe a high 1:3x to 1:40 is good. But with that said while I pulled a 1:20 at Lightning, my best time at Thunder was 1:47 lol, but that was my first day there and haven't been back since. I'm hoping to get down to 1:40 flat =)

You solo this time? Last time was kinda annoying, trying to get a clean lap with you. Well, I heard next weekend with PCA Del is completely booked. Let's just hope that it's not gonna be a train station.

Yep, I opted for solo despite having less experience at T-bolt. It's just beginner gets painful because after one session I feel comfortable enough with the layout but hate having to run with the yellow/green. Not to mention solo was cheaper, haha.

Figured worst case I'll line up in the back with intermediate and take it slow the first session and work my way up. I'll be catching you by day 2 =P

I absolutely love Tbolt and have far more experience there than Lightning. Tbolt is a much more technical course and there are many corners where the track is cambered in a way you can carry an absurd amount of speed through if you hit it the right way. Experiment with different lines and techniques through the octopus and figure out which one is faster. Some of the lines that felt faster were actually slower for me through there.

[CJ421]

I'm the opposite, I have a boat load of time on Lightning and just two days on Thunderbolt.
