Sway Bar Upgrade
I recently bought a 2002 CLK 430 Coupe with 30k miles. AMG body kit ans wheels. I love it!!!
My first Mercedes and I am kicking myself for waiting sooo long.
It seems to have excessive sway on cornering and I am thinking that it needs a heavier duty sway bar. Any suggestions?
Also, what suspension components should I replace at this age and mileage along with the sway bar? Plugs, wires, shocks, ball joints, dampeners, etc...
I am open to suggestions on all of the above.
I drive it pretty hard accelerating and cornering, but will seldom drive it above 90mph.
Also, looking for ways to improve the engine performance.

Thanks in advance
For handling, the first things I'd look at at tires and pressure.

How do I check the condition of the ball joints? I notice a clunking should on the left front when I turn the wheels all the way to the left.
What type of plugs would you recommend?
Ball Joints?
What are flex discs?
What type of shocks would you recommend? I dont want it to be too bouncy on the freeways.
How would one go about lowering it?
How can I improve the HP?
Also, what kind of tires would you recommend? My fronts are worn on the outside edge.
Since it is 8 years old, then from the schedule, I should do all of the following?
Every 2 years replace the brake fluid
Every 3 years replace the coolant.
Every 4 years or 50,000 miles check the condition of the flex discs.
Every 4 years or 50,000 miles retorque the steering gear bolts.
Every 4 years or 60,000 miles replace the fuel filter.
Every 4 years or 60,000 miles replace the air filter elements.
Every 4 years or 60,000 miles check the condition of the fuel filler nozzle seal in the filler neck.
Every 5 years or 100,000 miles replace the spark plugs
Thanks!

Does HR only make one type of sway bar for this car? How would I lower it? Different springs? What shocks would you recommend without making it too bumpy on the freeway?
What would you recommend to boost the HP without sacrificing gas mileage?
Thanks!

That's a lot of questions, somebody else will probably give better answers but
I used OE Bosch plugs when I did mine.
To see if the ball joints are dead, raise the wheel check for vertical play when pushed from the bottom. Just grab the wheel at 12 and 6 o’clock and see if there’s any play.
Flex discs sit at both ends of the drive shaft. MB uses them instead of u-joints. They're rubber and will crack with age.
I like Bilstein shocks, but Sachs and Koni are nice too.
To lower it “a little”, go with the CLK55 springs. Much lower and I'm out of my territory. One of the professionals (cough cough – CLKFAN – cough) can probably help you out.
Improve HP? Well, you’ve already go the big throttle body (2001 and later), so Ghosts exhaust is next. If you really want to go fast, rumor has it that 2011 ZX10 testing at Suzuka begins on Wednesday. We're all hoping our main man in Japan WiLL bust out the zoom and get us the inside story.
If you're wearing tires on the outside, you have too much toe in. My next set of tires will be Continentals, but PZeros and Pilot Sports are probably better summer tires.
Follow that schedule and you’ll be OK.

To lower it, i can do too many things, i can keep stock everything and change the pad to #1 from e320.
Now if u wanna lower it to be noticeable ,i like HR and KOni shocks and change the pad #1..
do a search and tons of threads will come up and see what u like and whats fit u the most.
to boost your hp, u can redo the ecu but i would wait and get intake or exhuast then ECU to tie all the mods.
U can go with headers since u got the v8 or if got money, u can go with Kleeman supercharger but again depends what u want
