I have E46 M3 convertible and I want to stiffen the car up all around. I installed a AC front strut tower brace (Which made a big difference in the front) and am now looking to see what I can do to the rear. Does anyone know what can be done?

Will bigger anti sway bars all around help?

Thanks

stiffening the car up? I recommend front and rear sways. You'll notice less body roll --- I think what you are feeling is not the flexing of the chassis; but, more body roll than anything else.

I had the ACS race strut -- sold it. OEM from BMW works just as well. I'd sell that ACS strut brace ... someone on E46fanatics will snatch it up immediately. I sold mine for $530 shipped. No haggling.
