I've got an '05 Sedan w/OEM Sport Suspension. I've been frustrated from the beginning by the fairly significant understeer - even on mild cornering there's a strong sensation of centrifigal force "pushing" away from the turn. Hate it!

Anyway, I installed some Stillen Sway Bars to start addressing this issue. I set them up soft/medium (front/rear) and, while this seems to help, I still don't feel enough control through turns and ramps.

What spring (and damper?) setup would help eliminate this? And how does front vs rear stiffness affect performance? FYI, my standard for suspension and handling was my '99 328i (Sport Pkg), which just seemed to "lean into" any corner no matter how fast - I NEVER felt this "pushing" sensation. The car just went wherever you steered itHow can I come close to reproducing that awesome "lean in" feel?

Help me, gurus...please?

PS In the spirit of "full disclosure", I'm still running the OEM 18 Sport wheels and godawful Turanza ER33's. These will be upgraded soon, but I'm trying to get suspension handled first.

 

get linear rate springs and adjustable damping rate struts. make sure that the linear rate springs have the front lowered a little more than the rear to induce weight biased to the front. front should have less damping (softer) than the rear to induce more weight transfer. thats the technical way. carefull though...you need some kind of neutral balance. the only time you'd really want enough weight xfer is when you're decelerating/braking before executing a turn.

you could resolve understeering issues with better gripping tires. S03 seems to be the talk of near competition tires less the wear characteristics. you could go with something like RT615 tires too.

depending on how you look at things...you can buy DOTR tires or S03 for less than a coil over system. but you can buy a simple adjustable strut set and springs for less than tires.

If all dont suceed, slide it...and steer the opposite direction
