You hear a lot about STi, P1, DMS, Tein, etc. on the board, but not a lot about LEDA.
I have nothing against those other suspension setups. In fact, I've never driven any of them, with the exception of the P1, so I really can't compare them.
All I can say is that I'm very happy with my LEDA setup (with 20mm rear anti-roll bar; Toyo RA-1 on stock wheels; Mintex pads; no other suspension mods). Notice that this is the straight Mike Shields advice -- worked for me!
I use my car for track days, and I've caught Integra Type R's, M3's, various pony cars, NSX's, and even a 500hp Cobra replica, and I'm not that good a driver! My engine is BONE stock, by the way, so it's definitely the suspension (and the AWD, of course).
Anyways, I credit the LEDA suspension with a lot of whatever success I have at the track.
