Without having to fully change my shocks/springs, would putting sways (H&R) as mentioned in other threads to be a negative impact and not worth doing? Or would the only way to get suspension to feel more 'm3 like' is to get full shocks and coil overs?
I wanted to just do modest handling to make the car a bit more responsive and less roll. As for tires, I'm currently running 19in GS-D3's.
Thanks for any feedback you can provide.

We are still trying to educate people how important an LSD is to an open diff car like the 335i, especially after adding JB3 and such.
To get the car more M3 like, the first thing is to add a good LSD unit like the Quaife or something similar.The stock suspension is actually not that bad, after the Quaife unit install you can balance the handling with either springs and dampers or anti-roll bars. However, do not add just a rear anti-roll bar if you don't have a good LSD, it will just make that inner tire spin much worse coming out of a corner. A good linear rate spring coil-overs will really help the 335i, then use anti-roll bars to balance between understeer and oversteer.
You wil never get the 335i to feel like the M3 unless you change the front and rear subfames along with M3 specific control arms. The M3 uses less bushings and more joints for less deflection and more feedback to the driver. Suspension geometry is also improved on the M3 vs the 335i.
