There have been a few discussions about coil spring selection to obtain proper ride height. Has anyone looked into the notion of adjustable coil over shocks so that the ride height can be dialed in? It would seem that there must be something on the market that could dimensionally fit...not sure about the mounting hardware...that might take a little customization but doesn't seem like it would be too hard.
I assume that a 4 link coil over rear suspension could also be employed although that would take a bit more modification.
The idea has been kicked around on several occasions, but I don't think anyone has succeeded. The front shock mounting "towers" on Series Alpines are too small to accept the spring cap / spring of a typical coil-over shock and can't easily be modified because they also serve as the mounts for the upper control arm fulcrum pins and the stops for the "droop" bump stops. Never say never, but I don't see any reasonably simple way to put typical adjustable ride height coil-over shocks on a factory Series Alpine front suspension.
A much simpler approach would be to start with a little shorter conventional spring and use shims in the spring pockets to adjust the ride height. Remember that Series Alpines have very limited front suspension compression travel (2-1/8" for the "king pin" cars and 2-3/4" for the "ball joint" cars) and lowering the front ride height reduces the remaining compression travel by the same amount. The "right" way to lower the front end of a "ball joint" Series Alpine is with "drop spindles" from a Super Minx, but they make unicorns look plentiful.
If you want to go high tech, Dale's Restorations (dalesresto.com) sells a complete front suspension system with adjustable ride height coil-over shocks, but it is primarily designed for Tigers and
starts at $4,350. Member Procraft has made coil-over front suspension systems for his customer builds, but I don't think he has sold any separately.
Several people have done 4-link rear suspension installations on Series Alpines (and Tigers), but I don't know of anyone selling packages or parts.
