AFAIK The US ZSP models are softer spung / damped and probably aligned for slower steering than the EU M sport models, so ZSP might be a downgrade from M sport?

This.

The Hunter machine had 3 options: standard, sport and ZSP. Someone else had already mentioned it on this forum but to me it made sense that the ZSP was the sportiest of the options.

I did wonder about this, but I don't have any of the M3 parts fitted, I didn't think they'd be able to get it anywhere near without the M3 control arms and wishbones.

I've already got Eibach Pro Sport springs on my E92 and will be fitting the Blistein B4's next month.

Are we all saying ZSP is 100% the better option for this set up?

Jon,

Great write up and review. I'm a bit sick of the rolly polly and lack of turn in precision of the 330i se i have. Only had it for 3 weeks an coming from the focus st I really miss the "chuck ability" noting of course the focus has a short wheelbase.

I can't stand a hard ride and can't go too low as Aussie roads are shite.

So I'm tosing up between the Eibach and B4s and the Eichbach FSD combo. And I am praying it wont be scrappage low or kidney busting.

The install cost here is approx $550 USD so I only get one shot at this!

Bumping old thread, i have b4s on my 2009 335i sedan with sport package. I am doing research to add eibach prokit springs and im afraid it will make ride harsh? How did it go with you?

I am also planning to upgrade to eibach pro anti roll bars/swaybars.

I hate to revive a dead thread, but can anyone comment on this? I plan on purchasing B4S struts, but I am unsure on what springs to go with. Car is a 2008 335i with the sport package.

I put eibach pro springs with Bilstein B4 (msport spec version) and that car rides fine, no more harsh than a factory msport that i have been in.
