D2 Coilovers
Still mulling over suspension options for my MY00 Classic. Has anyone got D2 coilovers fitted? They do a 'street' setup but the spring rates seem to be way higher than anything else I've seen ie. 392/224 lbs 
The guy at the importers is helpful and says if I find the springs too hard they can swap them for softer ones FOC on an exchange basis.
What do you guys reckon? Worth a go or not?

392/224 is unacceptable for our cars old or new age!
There is huge difference in proportional front to rear compared with every other coilover kit or complete suspension in the market or the factory setup.
IMO of course, choice is yours.

Kenny the bloke at Impulse is indeed v.helpful.
As you say 7/4kg/mm (70/40N/m, 395/225lb/in) is the listed spring rate front/rear, which I didn't even try. I went for 6/4 instead, as a starting point, which is not far off the original Leda 'B' rates, and a recommended combination for track-biased use in some quarters. Am finding this good on A-roads, not compliant enough for B-roads, and superb at Bruntingthorpe last Saturday
. No surprises so far then, in the general context of coilover suspension.As soon as the new spring arrives with Kenny I'm going to try 5/4, which I think may be pretty good allround. That's roughly the same as Leda's current 'bumpy roads' recommendation, and the same as some people run on ASTs (although 4/3 is more common with the latter). Am curious to try 4/4, maybe even 4/3, depending on the results I get with 5/4. Am aware that damper revalving would likely be required as some point along that route (tools not yet available in this country to revalve D2s).
Right now I'd recommend them for track-use, but I'll have to pop back in a month or two to tell you what I think about them for allround road-use.

Yup, I've had them for a couple of months on my daily driver '95 WRX which does the odd trackday and possibly sprints/hillclimbs next summer.

Durability? Any leaks?
Ride & handling?
B-roads?
Best spring rates to use?
General smile factor?
Cheers,
James.

Since switched to a newer road/track scoob but chose not to transfer the D2's over.
Durability? Any leaks? - one, which the guys at Sittingbourne sorted out under warranty. Design fault with very early units, and they upgraded both front struts to revised design.
Ride & handling? - 6/4 springs too hard, 5/4 good compromise for track and a-road.
B-roads? - oversprung and underdamped (not enough rebound), not the best.
Best spring rates to use? - difficult one. 4/3 might be worth trying, but basically a 180-210mm coilover spring doesn't have the travel to deal with potholes.
General smile factor? - good for the money, it handled really well on track and a-roads. Now using Apexes from Bren. For a pure road car I'd avoid coilovers completely though.
