To S52ish swapped Ti people: Suspension selection help wanted I will be buying suspension for my Ti project soon. I will be using a turbo'd M52 engine and only street driving the car. I usually go with H&R/Koni combo and pretty much hate coilovers for the street. That said, what have you guys used and had a good experience with? I like BMW stock sport package suspension in newer cars and hope to be similar or maybe a notch stiffer but not extreme. Thanks! Sent from my iPhone using Tapatalk |
When I bought my car in 2012, I rebuilt my entire suspension system focused around Koni Sports and H&R Sports designed for the stock M44 in my 1996 318ti. Once I swapped in a six-cylinder engine (first an M52, followed recently by an S52), I bottomed-out on the lower cross-brace over every speed bump in the area. As shown in my signature line below, I have since replaced the front H&R Sport springs with Eibach Pro-Kit springs (still using the Koni Struts discussed above), and this raised the front about 0.5". I also run a set of Racing Dynamics 28mm & 19mm swaybars, M3 front hubs/calipers, E34 rear calipers, braided SS brake lines, Hawk HP-S pads, DS-II wheels, Polyflex purple bushings throughout, and a Dinan alloy/carbon fiber upper cross-brace. However, I believe the 4-cyl front struts are still "overpowered." I just picked up a set of used factory M3 strut housings on Craigslist (free!), and plan to drop-in a set of Koni Sport inserts designed for an M3. Then I will be able to (properly!) connect the adjustable sway bars directly to the strut housings instead of the LCAs. |
Thanks for the info. Are you using purple powerflex in rear subframe and trailing arms? If so, how you like compared to poly? Thanks Sent from my iPhone using Tapatalk |
Power flex, black or purple, is poly. I've got poly in subframe and delrin in trailing arms. It's too harsh for MI streets honestly Sent from my iPhone using Tapatalk |
Sorry I was not clear. I have been thinking of using Powerflex purple bushings in my rear subframe and trailing arms of my Ti. I fee like the black are too hard as my car will essentially be a street car that has pretty good power, not a race car. Which have you guys used and can you share your thoughts?

Stock US M3 front suspension M Roadster rear springs with m coupe sway bar. Bilstein sports. Great street set up that's fine for the occasional track run. |
M coupe swaybar front and rear? Thanks Sent from my iPhone using Tapatalk |
M3 front sway; but they might be the same part number. |
