Car in shop, need new shock advice asap

[thothtp]

So I have been considering new shocks to improve my 135i in D stock autocross for a while now, but something has come up. Pulling out of my driveway a few days ago I heard a bang and a horrible rubbing sound, pulled the wheel to find that my front right OEM spring had broken right in half. The car is at the shop now, and I need to decide asap which shocks I should pick up, so that they can replace them at the same time as my springs.

I am a casual autocrosser, no national level for me, but I would like to improve the handling a bit while I am in there. The car is all stock except for an m3 E93 front sway, and Michelin Pilot Super Sports. 2008 135i with 60k miles. Because of the stock class rules, I am going to keep the oem sport springs, but I want to change the shocks. Not much else I can do to the suspension without leaving stock class.

Since this was a surprise purchase, budget is an issue. I am looking mostly at the Koni Yellows or Koni FSDs. From what I have found, I can pick up Koni yellows from tire rack for $730, but without the externally adjustable rear damping. HP Autowerks has them with external damping, but they are $1172. Yikes. Or I can pick up a set of FSDs for $800.

So what is my best option for autocross? Will I be happy with the FSD's? Ride comfort is semi important, but I want to improve my autocross handling. Or do I need to bite the bullet and get adjustable yellows? for $400 more :-(

Thanks for the asap help guys, I really appreciate it. This is my Daily, so I need to order today.

Give Ground Control a call and see if they can help you out with the externally adjustable Koni's

I'd bite the bullet and go for the external adjustable ones... That being said you can order just the front 2 from one place that has better pricing/shipping and then order just the 2 rears from HPA or TCK

I would probably go with the yellows except the price difference is so hard to justify.

How are the Koni sports on stock adjustment in the rear? I could pick up a set of them from Tirerack for cheap, and just adjust the fronts for balance while leaving the back as is. Gives me adjust-ability in the front at least, and saves money, but is it as good as the FSD's?
