The only worthwhile one is the koni h/d adjustable, Heritage used to do them, may still possibly, i see them as weight i dont need, and haven't used one since my rallycross days, road or track, t'beam or mac strut, and they can also cover up a problem, 'damping it' obviously, with good set up and good wheel and tyre management on events, such as NOT being an F1 driver picking up rubber, i get NO shimmy or shake even with big wheels pushed out to the scrub limits, if you have shimmy, adding Castor adds no weight to the car and will cure it and add more feel. LOTS of rubber builds up INSIDE the front wheels on trackdays, takes 5 mins to pull it all out every run, and it dont half stick in there.
I raced a G.P midget on an oval onetime and this had TWIN s/dampers on it, not my car, and it was a front runner BIG NAME owner, i had some engine work and parts on it, i tried to comment and change things after practise, and would have softened the whole thing off, it was so stiff all round, bumps where the enemy, with revs soaring on them, so maybe the s/dampers were necessary, at least how he liked it set up, ovals are SO specialised, but id have liked to run without them.
Mac strut cars seem more prone to shimmy, but again, find the reason rather than damp it out, on a beam bug, one caster shim for the street works magic.
