My Ride: 2002 325xi
Next Project - Suspension System Rebuild - Any Suggestions?

Hi all,

I have a 2002 325Xi (non-sport package) all stock except for 18 x 8.5 CLS style wheels with Michelin Pilot Sport A/S P245/40 ZR 18 tires. ~114,000 miles on the odometer.

Will be spending the Thanksgiving holiday weekend in the garage replacing right (and possibly left) front axles. See prior post as to why I need to change out complete axle instead of just CV boots. Suggestion: If the CV boot is torn do not delay in replacing the boot!!

Next project is to install springs (front & back), front struts, rear shocks, front control arm bushings, and rear trailing arm bushings. I will be doing all of the labor myself.

The car is a daily driver used here in the city and for nice long drives out into the country. I am considering installing the following:

Eibach Pro Kit Spring Set
Koni Sport Yellow - Adjustable Front
Koni Sport Yellow - Adjustable Rear
Powerflex Urethane FCAB & RTAB

Any comments/suggestions? I have read through all of the previous posts on this subject here on the forum. If I did not go with the above I would probably go with the H&R Sport Spring Set and Bilstein Sport Struts/Shocks.

Also, while I am doing the above install is there anything else I should consider?

Thanks,

Doug in Lakeview

Good choices for spring set and shocks/struts and bushings. I just installed a set of Powerflex Urethane Front Control Arm Bushings (had to replace a lower control arm that had a bad ball joint). If you need any tips on removing the old bushings and installing the new Powerflex ones, drop me a private email, be glad to give you some pointers (reyomot@verizon.net).

H&R springs are also good (I've used them a lot) and Bilstein Shocks and Struts are also good and a little bit cheaper than Koni, however not adjustable.

Other things to consider while doing this; front and rear stab bar replacement or front and rear stab bar links, front shock tower brace, new rear upper shock mounts and don't forget to check your steering tie rods and front inner and outer ball joints on the control arm. When I have replaced spring sets, I always replaced all the rubber parts that the springs set on and the upper front bearing assembly, and all bushings front and rear, and the front lower control arms and ball joints. That way you have a complete, brand new suspension system and no need to go back in there to replace parts for a while.

Definitely go with powerflex! Good choice. Use the centered e36 m3 powerflex fcabs and the normal e46 rtabs.

If you go with bilsteins, use e36 m3 sports in the rear.
