Suspension Upgrade Help

CDNBimmer · 07-28-2013, 05:37 PM

07 e90 335i without the sport package. The car currently has upgraded staggered VMR 19" wheels (11" rears, 9" fronts), Catless DP's, FMIC, BMW PE, ECU tune. Needless to say I went for power first and now the car needs help maintaining that power in the corners. Probably did this backwards but it is what it is!

The car is a daily driver and will be driven in the winter, so I don't want to be extreme but I'd like it to corner likes its on rails.

Based on my research I thought a good start would be sport springs and front/rear anti sway bars (ie. cobb or Eibach kits)

My question for all who have done upgrades are:
1. Are these the most cost effective changes that will yield the best results? Will this make a noticeable difference?
2. If not, what else would be better?
3. How many hours is standard to install these items?
4. Probably a bad idea to open this door, but what brands do you suggest? Any reason why?

Thanks in advance for everyone's feedback!!

LSD would be most beneficial for keeping the power down.

Definitely do not get a rear sway bar without an LSD if you're already having trouble putting down power in a turn. It will only make it worse.

I'm trying to eliminate/reduce body roll and improve handling in general.

Power to the road I'm not as much concerned about.....yet
