Can anyone suggest a lowering kit that works good with crossfires? Hopefully something not too pricey. I've never done this before, although im sure i can do the work myself (or with my buddies). I've seen a couple on the big sites around here.

Eibach Pro Spring Kit for Crossfire
Koni Shocks- Front
Koni Shocks- Rear

I really just don't know how the adjustable works. If i need to replace the shocks, or the springs, or if both are required?

Thanks

 

Eibach is tested and fitted for the Crossfire.

 

All I need is the springs?

 

Yes, only springs needed to lower, but then maybe some thinner spring pads and a new alignment which means you may need rear camber arms on the rear and adjustable bolts for the front.

 

the koni shocks fit in the oem location. they have an adjuster **** on the top of the shock that adjusts the firmness. the springs are installed in the oem location also and they are either shorter or progressive wound. its not hard to do but you will need a compressor tool to do the job correctly and safely. about 180$ from ebay

 

I have run both cut springs and Voghtland springs. I do believe that lowering the car improves the look of the car. Just know that lowering the car does not improve the ride. Here are some options that I have first hand experience with:

1. Just use the thinest (one dot) spring pads will lower a little. Use stock shocks

2. Cut springs. Cut 3/4 or 1 full coil off each coil. I cut one full coil and it looked great. With stock shocks you need to trim about 1/3 off the rear bump stop. This will only cost you your time.

Eibach or similar springs. I used Vogtland Springs which are very good German made springs.

I personally didn't like the stock shock after I lowered it, but my stock shocks had about 60K miles on them at the time. KYB was improvement over stock and priced reasonably. I now have Koni's which in my opinion are the untimate if you can afford them. Bilstein makes great shocks but I am not aware of anyone using them on a Crossfire. If you go with Koni get the Sport version. The only difference in these and the regular yellow's are they are for a lowered car. Hope this helps.

Changing springs is easy in the back but the fronts are no fun at all if you don't have a Mercedes specific spring compressor.

I used the collision repair bolts in the front to get the camber correct and the K Mac kit in the rear. I don't reccomend the K Mac kit because of how hard it was to remove the old bushings. A camber link would be a better way to go if you are worried about camber.

 

does anyone know the quickest way to buy or borrow the spring compressor tool? i have to do my springs and shocks immediately because i hit a pothole that really messed up my alignment. so i want to do this all at once asap. i have all the parts but the compressor tool...

 

Here you go. This is the one you want. Also I would highly recomend the Voughtland Springs.

i wanted to give you a quick update after the dragon gtg. i installed my koni shocks and kept the stock amg springs in place. immediatly with the shocks cranked to the firmest setting then back off 1/2 turn the car was stiff as a brick! throwing the car into tight turns yielded little to no body roll andf the car responded to my power very well and predicably. added my wavetrac and the car was fun as can be. added my 6/4 caliper setup and i felt fearless in all but the tighest of turns at high speed!! bottom line the konis are great and a progressive build up of suspension and brakes and driveline yield a car that feels safe at all speeds
