Tapatalk is being removed immediately. There are security issues and there is no justification for having it anymore. I apolgize to those die-hard Tapatalk users but you'll need to start using the forums mobile version instead.
@e9allan - FWIW, I’m taking Sports off a 2002 and going to HD’s. Sports are firm to the point of being quite harsh over bumps. I think it’s also hard on the vehicle, causing rattles and noise where I don’t think a more compliant setup would. Over time I do think it could cause more issues than a something with more give.
The car handles great, but I’m told by knowledgeable people I won’t lose much - will just have some more lean. Have thick sways and stout tower braces. Point is, lots of ways to get better handling without super firm struts/shocks.
According to the E12 E24 and E28 people, the valving in the HDs and Sports are the same. The difference is in the shaft or stroke travel. The shorter stroke of the sports provide for a harsher rebound which makes them ride rougher On the front strut housing where the the spring is totally captive this shouldn't make a difference. But on the E12s etc, when using the HDs, due to the length of the stroke, when you jack the car up, the rear springs will dislodge from their perches because the spring is too short to be held captive. However, Bilstein will put extra grooves on a rear shock body allowing for ride height adjustment and capture of th springs
