a) As Dave has said, they are overkill and we don't recommend them for road use. The gas pressurises the damping oil to 175psi, the purpose being to raise its boiling point. For fast road and track use, you would never boil it anyway, but this pressure does put a lot more loading on the seals and these need more frequent maintence. Leda circumvent the problem of fluid temps in two other ways... firstly the damper contains 150% of the target fluid volume, secondly the oil in circulated unidirectionally, irrespective of whether the piston is rising or falling, and the damping oil is always drawn from the bottom of the reservoir. This ensures the valves always work on fresh oil and the temperature is kept stable. Leda use Silkolene damper oil, as do Proflex and Ohlins.
b) You adjust it to suit the conditions. Gentle drive, mad cross country blast, smooth dry wet, wet track etc. It takes less than 1 minute to adjust all four corners. You can also adjust the ride height, for a track day, but most people leave this at the factory setting.
c) I strongly agree with brakes and suspension first. If you are fitting really big brakes (eg AP 6 pots) and are using slicks, you may want to fit suspension at the same time. This is because you can apply so much braking that you will be on the front bump stops, with the rear wheels totally unloaded, with the standard suspension. Good suspension will hold the car flatter, giving less likelyhood of locking a rear (or activating the abs, which then kills the braking power) and making the car more settled as you come off the brakes and turn in.

Its not what you know and its not who you know, but what you know about who you know
They look the absolute nuts, should get them on in the next couple of days. Have heard great things and your times back this up. Good site, with great pics, by the way
