Thumbs up Review: Dinan Stage 2 Suspension (E90 335xi)

My goals were simple. First priority was to maintain a comfortable ride quality, nearest as possible to stock while retaining the stock run-flat tires. Second, significantly reduce body roll during cornering. Third, get rid of the 4X4 look. I decided to purchase a Dinan stage 2 suspension.

The Dinan stage 2 suspension is offered in a XI/xDrive-specific application that reuses the OEM front struts. It consists of custom-valved Koni adjustable rear shocks, performance springs (front and rear), rear sub-frame bushings, bump stops and a rear sway bar.

To my surprise, the ride quality is an improvement over stock -- no more tooth jarring pot holes that sound like their causing welds to fracture. It handles imperfections in the road surface with grace and remains firmly planted during aggressive turns.

I'm comforted by the fact that this suspension system wasn't available in 2007 when I originally took delivery of my XI. Otherwise, I'd regret not having purchased it day one!

Looks great! I like the mild drop that keeps the practical side of the xi for winter.

Thanks for sharing. You don't see too many xi's with the Dinan suspension setup, mainly b/c of its price. Definitely a rare setup and was actually considering this but i didn't like the fact that they didn't swap out the front struts.

Are the rear dinan koni shocks yellow/adjustable?

No, an independent could do the install as well. Unless you want to DIY.

Dinan extended their sale until May 28th, however, I don't believe that their suspension systems are included in the sale...but, I could be wrong.

Their E90 325xi suspension includes front Koni front struts as well. Check out their web site. I suggest calling them; their very helpful.

Thank you! I picked up the car on Friday and the pics were taken on Saturday. I haven't noticed any settling.

I could be wrong, but I don't think Dinan replaces any of the front struts on xi specific cars. Koni never made/released front struts for our cars.

Koni doesn't offer front struts for the 2006 E90 325xi directly. Dinan does.
