My english are not great so please bare with me....
FYI. I just installed rear Bilstein Sport from GS and it works correctly.
The only different is GS shock body is 1.25 inch longer and EVERYTHING ELSE MEASURED UP TO OUR OEM, so you'll need to cut your bump stop at lease 1.25 inch. Now your bump stop should be 4.25 inch from the shock body.
SC OEM piston rod spacing between bump stop and shock body is 4.25 inch. It'll compress about 3 inches once car are lowered on ground. That leave 1.25 inch of piston travel.
Im lowerd on TTE springs with 20x10.5 et30 285\30\20 hankook and have yet to bottom out with this setup.
Let me know if need more info.

I' M DOING THE SAME THING YOU ARE. YOU SURE THE GS300 DAMPERS FIT IN THE REAR OF THE 430SC. I HAVE THE BILSTEIN SPORTS FRONTS AT BILSTEINS AT THIS MINUTE BEING REVALVED FOR THE 430SC. AGAIN ARE YOU 100% SURE THEY FIT. I SEE YOU MUST CUT THE BUMPER STOPS. HOW MUCH OF THE BUMPER STOP DO YOU HAVE TO CUT OFF AND HOW MUCH IS LEFT. DO YOU BOTTOM OUT AT ALL AND HOWS THE RIDE? CAN'T BEAT THE BILSTEIN RIDE, I'M USING SWIFT SPORT SPRNGS WHICH DROP ME ONLY 1/2 INCH REAR.I CAN USE ALL THE INFO YOU CAN GIVE ME.

I am 100% sure it will fit and works correctly, because i have it on my car right now. Since everything else measured up to our shock except the body are 1.25 inch longer. By cutting the bump stop 1.25 - 1.5 inch, now the bilstein have the exact same piston travel as our OEM before hitting bump stop.
I'd recommend to cut 1.5 inch since the bilstein sp are stiffer compare to OEM.
I am lowered 1 1/8 inch on TTE springs and i have about 1.25 - 1.5 inch piston travel same as OEM i had on before. If your car are not lower than it'll be 2.25 - 2.5 inch travel.

i have no experience with HD sorry, but i can tell you that the sport are very stiff and should get softer over time though. I recommend install the sport fronts first and see how you like it than decide the rears.
How much you plan to drop ?

I also compared the stiffness by pushing the pistons on a weight scale and the OEM takes only about 30 lbs to hold the piston rod press in half way and 90 lbs for sport. Hope that helps.
