If you want answers appropriate to you...
...define just right, not enough, and too stiff. My 32 is just right - for me.

when reading over post install reviews i have seen that people say that the 28mm bar may just be too thick someone not too long ago said this: The downside is that it really doesn't add any extra sense of 'grip' and I notice the soft springs/dampers even more than before. Making quick transitions is actually a bit unnerving. The springs compress, but then the stiffer bar seems to 'catch' the roll and stop it, but the whole experience doesn't feel balanced. I guess that is the issue in a nutshell, adding the stiffer bar has unbalanced the ride slightly. --- would adding the 26.5 bar make this just right, or is this accurate and is the 28mm just maybe a little too thick for stock 135i suspension?

the idea behind controlling roll is to prevent positive camber on your tires during cornering. neither one of these bars is stiff enough to do that with stock camber. youll need a pyrometer to test this for yourself though. the 28 mm bar is actually 26.5 mm between the bushings as well. I doubt its actually much stiffer than the 26.5 bar. I would not be worried about too stiff with either one. you also dont want to make a decision based on one person whom you dont know. many people have ordered and loved the 28 mm bar.

You really should start with a full shock/spring or coilover suspension upgrade first and then add a sway bar later to fine tune your system. This is much more expensive, but for a significantly better ride and grip, especially when on a track, this is the way to go.

I have never been a fan of using stiff bars to compensate for weak springs.
Personally, I'd rather run the OE bar and do it right by changing spring rates and damper rates. Get a good set of coilovers and you'll be impressed. Shop TC Kline or Ground Control and run linear rate springs. I use to run really stiff bars and H&R springs on my E30. Hated it. The bars were so noisy and really took away from the independent suspension. Not to mention all the new chassis fatigue stiff bars will contribute to. Just my two cents. |
