2006 C230 Performance Modifications
Especially considering you are just starting out at the track. Get some good track pads and see how that works for you. I recommend Carbotech Engineering, as they can line a set of backing plates with any pad compound you want.




Do people swap brake pads for race day like they do wheels/tires??

unless you really want those extra braking surface provided by bigger pads. FIY my Brembo 355mm caliper probably only weight about 1-2lbs less than the C32/55 caliper, but the rotors weight at 16lbs is 9-10lbs lighter than the stock.
I have seen/heard people that do swap the pads during track day, but mostly are those seasoned veterans.

It only lasted 2 years in the US.
To answer the original questions...
>>>Brakes
- Complete kit, upgrading to C55 brakes or a Brembo kit or something.
- Component upgrades (pads, 2-piece rotors, SS braided brake lines, racing fluid, etc.)- AMG Brake Kit, around $1K from Evosport or buy the components seperately. Evosport also has the 2 piece rotors, but I think they were $1500 + for 2 ?
- Air ducting to the front brakes. -

Wheels/Tires
- Upgrade from 17" to 18" wheels to allow for larger brake rotors/calipers.
- Get super light weight wheels.
- R compound. If I have the cash: one set for autocross and one set for track.
-Correct me if I'm wrong, but you'd be better off with the 17" for your AX.
Suspension/Alignment
- I don't know much about this area, please enlighten me!-
Lots of choices, but basically springs/coilovers + sway bars-
$500- $3000. TEIN is popular around here, the SS version has adjustable shocks which would be very useful in AX.
Weight
- There must be some way to make this pig weigh less. I have the fold-down rear seats. Are they difficult to remove? What can I easily remove on Friday for a race on Saturday, then put right back in on Sunday?
I've wondered about that myself.....try it! I've heard removing the front seat can result in an SRS error, but not sure. Start with removing the spare of course and tools and anything not tied down!
Intake/Exhaust
- Are there really any significant power gains here?-
Yes. But it will cost you $$$$$$$$$$$$$$$$. Since you are under warranty, you may not want to mess with this....
I love my header, and freeflow etc. Kept the 2" pipe though, since I have supercharger and you need to maintain backpressure.
Miscellaneous
- What else helps?-
Chip? Sprint Booster? While the SB doesn't increase HP, the increased throttle response might help in AX, and be worth it. In fact if I was AX'ing, I'd go for that 1st! Search on it, tons of info.

To combat the slow MBCA track schedule, I joined the BMW Car Club of America (www.bmwcca.org). I haven't seen many autocrosses scheduled, but they love to drive at the track!

Please tell me how to get started with solo'ing and autocrosisng. I have a 2007 C230 and I'm still learning how to drive it after 25 years of front wheel drives.

Our local Porsche Club section allows others to join in on their driving events. I believe this type of policy is decided on locally in their club, so you may not have this option.

Not only is it fun, but it does teach you the limits of the car, and the limits of your ability. When the time comes to perform evasive manuvers on the public roads, you'll know what to expect from your car.
The reason I ask is I was looking to change my rotors (stock to stock) and getmercedesparts directed me to CLK55 rotors and I remember reading the 350 uses the c32 caliper.
Anyone?
Thanks

The 2005+ C230 Sport sedans had 2-piston fixed calipers, and used a slightly smaller rotor than the C350/C32/C55. The 2004.5 and some 2005 Sport sedans got 4-piston fixed calipers that LOOK like the C350/C32/C55 calipers but are not, and these brakes also use the smaller rotor that matches the 2005+ 2-piston setup.
As far as I can tell, the C350/C32/C55 can use the 2-piece floating rotors from the SLK55 and CLK55, but they are something like $500/rotor.

In other words, there will be minimal performance gain for me to go with C55 brakes since I have a 06 230?
