I am! Top Gear is currently working on the car, and I should get it back next week

I just wanted to follow through with the exhaust project before wrapping up my time with the M3. I'd hate to be the guy who built up all the momentum just to kill it haha. It's also the middle of winter in Chicago, so locals aren't exactly dying to buy an M3 right now.

For the record, I'm not selling the car due to the exhaust tone (which is fixed now) or the suspension. I just don't have the time to maintain 2 garage queens anymore, and would rather the M3 go to a new home.

Sorry for derailing my own thread, back on topic.

So, same dampers as B16 but with custom springs?

They're different part numbers. Both are the B6 product line, but B16D version are matched to the springs. Generic B6D are more compliant.

No, dampers are technically not the same. They look similar but the tuning/valving is different since the B16's are made to accommodate a higher spring rate as compared to the B6's which are tuned to work with the OE spring rate.

Only one the DSC sport module is not compatible with is the KW DDC.

JetBill used the DSC sport module with the M2 and raved about it.

Also the other option is Tractive coils that Litchfield and Dinan run on their m4s that all the reviewers have praised in the past.
I contacted DSC awhile back for this solution and they said if they got enough traction with our platform, they may support it. Maybe I need to look into their controller again.
Jetbill used OEM EDC shocks from m3 with the DSC controller on his m2.

I think most lowering spring rates would be fine with the B6s since the deviation from stock is minimal.
Only question is if the B6 shock body/shaft length has enough travel/response to accommodate the reduced suspension travel.

True, spring rate on an aftermarket spring kit would likely only be between 10-15% and wouldn't warrant or require a tuning change to the shock, I agree with that. Since Bilstein obviously is a large enough company to change out tuning of their shock with their B16 kit, might as well give it specific tuning to work with the spring rate of that B16 rear spring they provide with the kit.

No need to change the body, the shaft or the travel length to accommodate any reduced suspension travel on an already low car to start with, that wouldn't be necessary with a shock already accommodating of how low the M3 is traditionally from factory. If we were talking about a non-M height versus a lowered height, sure that would likely warrant the necessity of what Bilstein calls a B8 shock which is intended for lowered applications for that segment. With the M3, no B8 would exist since the B6 is already accommodating of how low the vehicle is to start with if that makes sense. No change necessary so no worries there.
