Performance Power upgrades Kleeman

Hi guys i was browsing on the evosport web site and i saw two performance products for my c230k.


K23 Power Upgrade Kit (klm-203uk2) Includes steel ring-type pulley @ 599$ or so.

I was wondering if any of you have purchased these items. Was the gain as expected? is it worth getting, what would be my expected 1/4 times.

and what about the underdrive pulley kit, they say it has or give 30+hp.

Anybody have that?

thanks for the feedback

I've got one KLEEMANN Ring Type Pulley I am going to be giving away at the next meet I try to throw. It will either be in NJ or MD, depends on where I land, long story.

It's for the 2002 C230 Sport Coupe with the M111 2.3L motor. Is that what you are driving?

Don't blame you Nuk, don't think anyone on this forum is running that ring on a C230K except you. The price is right though. Are you getting the test s/c to replace it or another pulley?

Depends on how "stiff" you want the suspension to become. The Eibachs are thicker than AMGs by a few mm. Also, you want to keep in mind that the sway bars compress one side if the other is externally compressed. In other words, you can't go over speed bumps diagonally (if the car is lowered) anymore, it's useless. I have the Eibachs, and my driveway is steep enough that every time I back out or pull into my garage, one of the rear tires literally lifts off the ground. That'd also be a consideration. But as for handling itself, it's really great.

and how much does the kit go for?

i'm thinking of getting the H&R coil-overs and dropping it 2,5 inches front and back. I'm not too scared about hitting speedbumps. At least i hope it won't hit.

If I remember correctly, somewhere around $300 or $350 USD

And as long as you're careful around major bumps, you'll be fine. You'd have to be careful with coilovers installed anyways.
