The 2002 CLK55 that I recently bought came with a set of aftermarket wheels that just didn’t work for me. They were Katana GTM wheels, which look fantastic on the company’s website, but the 18×7.5 wheels didn’t have enough “dish” to look proper on the CLK. The fronts were OK, but the rear wheels had improper offset and were tucked way too far inside the fenders, giving the car an anemic look. Of course it doesn’t help that the 7.5″ wide wheels will only support a 225-40/18 tire.
I decided to solve this problem by killing two birds with one stone. I could sell the Katana wheels and recoup some of what I paid for the car, and I could clean out my garage just a little by putting my old factory E55 wheels on the CLK.
I took the CLK to the Woodburn Dragstrip for the first time today so I could get some baseline numbers on the car while it is still full-weight and 100% stock. While not the numbers I was hoping for, I did learn a few things and started the process of getting to know this car’s personality at the track.
If you are looking for better traction for your E55 you have come to the right place! The hot ticket for cutting your 60′ times is a set of Hoosier DOT Drag Radials mounted to OEM Mercedes CLK320 wheels.
The rearward bushings in the front lower control arms of the W208 CLK are known to wear out rather quickly. They are “loose” by design, having an air gap around more than half the perimeter of the bushing, meaning there is only about 2″ of rubber holding the outer shell to the inner sleeve. This not only leads to premature failure, but often leads to vibrations in the car, even when the bushings are new. I’m sure the Mercedes engineers had good intentions, but in practice these bushings have been a sore spot for many CLK owners. You can replace the factory units with aftermarket polyurethane bushings from Powerflex if you want a performance and reliability upgrade.
How can you tell if your Mercedes needs new motor mounts? Well…
I did this simple test by opening the hood, starting the car and putting it in drive. While holding the brake, give it a little gas until the engine starts to torque over. If your driver’s side mount is completely separated like mine, it will be obvious. I thought the engine was going to jump right out of the car!
The M113 and M113K motors in the AMG Mercedes are notorious for destroying engine mounts because they make a lot of torque. Replacing CLK engine mounts is not hard, but it does take a lot of patience, and one special tool. My car happens to be a CLK55 AMG, but this DIY is applicable to the 1998-2002 CLK320 or CLK430 as well. Read-on if you want to learn how to do this job and save yourself about $500 compared to what the dealer would charge you. Continue reading “CLK55 Engine Mount Install”→
I’ve been racing my 2004 E55 for the past three years and now that it’s running in the low 11’s I risk getting kicked out of the track at every event because it lacks a rollbar. Since it’s my daily driver I don’t want to cut into it so I decided to retire it from race duty and buy another car to use exclusively for drag racing. This will allow me to be aggressive on the weight-reduction and tuning fronts, as well as add any safety gear necessary as my ETs drop and the MPHs go up.
…it’s a running, driving car and I only paid $850 for it!
I decided to go with a W208 CLK chassis because they seem to be the lightest cars that came with the M113, and I definitely plan on doing an M113k powerplant. After a few months of trolling the various car-selling websites, I came across this beauty:
She’s a 2002 CLK55 with 219k miles on the clock, but the best part is that it’s a running, driving car and I only paid $850 for it! Even with shipping from LA to Portland the total cost was only around $1500. Of course for that kind of money it does have some issues, but they are typical stuff for any MB of this era: needs a battery, motor mounts, rear main seal, front LCA bushings, new tires all around and a good cleaning. It’s got some other issues with the electronics, but for a racecar, I don’t really care about those too much.
