Can I make an e90 335i handle better than an e90 m3? What part will be needed?

Sure. If you have enough money, it ain't cheap.

Right now I have coilover, dinan sway bars, and a strut tower brace. Looking at powerflex rear bushings. Any other suggestions?

Lsd, M suspention arms, subframe bushings, and wider tires.

Camber plates (set to max positive caster)
Lightweight wheels
Michelin PSS tires
All M3 links and arms except toe arms
Adjustable toe arms with Aurora spherical ballends
All spherical bearing retrofit
-->upper front control arm
-->inner rear lower camber arm
-->trailing links
Race dampers and springs (very expensive)
-->relevant ride height and alignment
Solid brake caliper guide pin bushings
Solid engine mounts
Solid transmission mounts
Solid differential mounts
Solid rear subframe bushings
ATI Super Damper (coming soon)
Clutch type limited slip differential, 1.5 way

I'm sure there's more but that's a start...

All that huh.....I'd sooner just buy an f80 m3. Too bad the e90 m3 is n/a

There ya go. Then again, the f80 needs about as much work unless you get one of the new GT3 cars. NA or FI has nothing to do with it.

Really?!? An f80 m3's suspension is not as good as the e90 m3?
And I just said too bad the e90 m3 is n/a because it's soooooo expensive to add power without FI

Not really, no. Street cars can't be made to handle particularly well without severely degrading ride quality, at least not without spending a stoopid amount of money.

You can mod both chassis to get to a decent track level performance but neither is all that swuft, imho anyway. The GTS wouldn't exist if if they were.

Power is meaningless unless you're just dicking around on the street which is nothing compared to tracking. And the driver skill necessary to make use of it is not easily learned and it certainly isn't learned in an overpowered car. It's a commonplace and I've seen it many times at the track. If tracking isn't your target than handling isn't necessarily what you're after, probably.

The part of you going to the local dealer and trading in your e90 335i for another vehicle You might even have some money left as there are few cars cheaper than e90 335i that can out handle e90 m3

Forgot to mention you'd need a front ARB and stiffer bushings as its roll stiffness will contribute to defining the front spring rate, among other parameters. Without an engineered setup and corresponding alignment, as a function of choice of tire, all the parts aren't worth anything and would be somewhat pointless to install.

Although I suppose it's possible to stumble around and guess one's way to an adequate setup but it strikes me as a serious waste of time and resources. Best to find a competent race shop, one that really does race professionally, and have them work out what's best for your target use.

Oh yeah, you could always resort to lapsim although measuring all the necessary chassis parameters is nowhere near easy. SAE's Race Car Chassis Dynamics is helpful but way too complicated to easily use. Yeah, chassis setup's a bitch.

Never said anything about a trade in....I'd sooner sell it or part it out.

Honestly with the poweflex rear bushings you would probably be pretty close. Just install all the m3 arms and you would probably be already beating an m3. Put on some light 18" wheels (nothing bigger) trailing arm bushings would help putting power down. And an lsd would just be a cherry on top. No need for a rear sway bar since it would probably make it worse.
