2000 to spend, what would you prioritize?
If you guys had an LCI e92 328i Xdrive with only 2k to spend on a suspension upgrade to make it as close to the OEM sport suspension and overall better handling, what would be your top cost effective choices before inevitably running out of money? Thanks for your time in advance.

xdrive suspension upgrades
A good way to word your question. I strongly suggest reading the referenced article for some guidance. It is the best I have found:
https://dreamingin302ci.blogspot.com...ve-handle.html The first response has merit. You might want to consider the Powerflex urethane bushinngs for the control arm to chassis bushing (PFF5-5701). Not as solid as the mono-ball but less expensive, less prone to winter corrosion issues, likely less NVH. You should examine the joints of the other front control arms as well as the tie rods while you are in there. Rear sub-frame bushings are a bear to replace. It took me about 60 hours, but YMMV. I used the Revshift urethane bushings (less expensive from FCP). Less sub-frame movement over bumps on curves, no noticeable increase in NVH. If your tires need to be replaced, putting money into better rubber is likely good performance value, but durability will likely go down. I run Continental DWS 06 plus in 225/45-17 in the summer and like them as a sporty all-weather tire. I run dedicated snows in the winter. Outside your budget, but I think the ST coil-overs are perfectly matched to this car for daily sport use. They are the same as the KW 1, but with painted steel bodies rather than stainless. The rear shocks are prone to early failure, so I would consider some Bilstein B8 or Koni when the shock fails. Keep the springs. Let us know what you end up doing. |

Our modification objectives and approaches are very similar. I also chose to stay with 17" wheels for reduced weight. When you do buy new tires, consider the tire weight also. I understand the Michelin Pilot tires are excellent, likely better, than the Continental for summer only conditions.
My brake options are limited by my use of 16" rims for winter tires. If you stick with 17" rims year round, you may be able to use two-piece rotors and/or aluminum calipers. The rotors would be the first priority as rotating mass, but lighter calipers will reduce un-sprung mass. These would not be in your first priority list, but something you might consider when your brakes need replacing. An excellent build article for maximizing performance from an N52 car has been written by "BiginBoca" on this site. His emphasis is weight reduction. His car is RWD but many of his modifications are also applicable to an N52 xdrive. Excellent information, well-researched, tested on the track. There are others with a lot of "earned" experience in suspension set-ups on this site. Most are very generous with their time and helping others. Keep an eye open for the regular posters in the suspension forum and the track forum where suspension tuning is paramount. |
