Hard to quantify exact lap times per mod, unless you do them one at a time and test in between in similar conditions. But I've gone over 7 seconds faster at TWS than I went before the diff and swaybars and bushings.

You'll need all the same suspension mods on an M3 (minus the m3 control arms obviously) but cooling and LSD should be fine on an M3. M3 owners replace the same bushings 335 owners do.

If you like to tinker and make your car unique and your own, I'd say stick with the 335. I feel the engine has more potential than the high strung V8 of the M3. But if you want plug-n-play, the M3 is easier.
