Installing lowering springs.

[T.Hanson]

I'm on a roll asking mysterious questions, or I've been kicked out.

Installing vintage Alpina (Eibach) springs:

Is there a top end ? If so, smaller or larger diameter coil end, tighter or wider spaced winding goes up ?

Rust needed removing, as did the crunchy rubber tubing. Never occurred to me the rubber tube cover was anything but protective. Now I read it has a noise function ?

Can I just visit a hardware store for some vinyl tubing that fits, or am I off to Bavaria for custom Alpina for $60 a foot ?

A pair of my front springs had this plastic, I removed it and installed new rubbers on the lower/upper perches. No difference in sound. I thought it was on there because there was previously no rubber on the perches..

Alpina (Eibach) lowering springs increase in rod diameter one end to the other. Go figure how they do that. From a race car suspension tuner: the fat diameter goes on the bottom. Progressive wound springs the tighter coil spacing goes on the bottom.

Correct-a-mundo on the rubber/vinyl tubing on the spring. It's an anti-squeak device in lieu of the rubber spring pads. No pads in olden days or on race cars could cause steel on steel squeaking.
