3/4 way - as in 3 or 4 way adjustables, 3 are normally 1 rebound (on the stem) and Bump in fast and slow (on the canister).
Uldis - the spring platform is NOT an adjustment as far as dampers are concerned!
The Nitrons (that we are talking about here) are single way adjustables, ie. they have 1 adjusting coller (or Knob on older ones) that adjusts both the bump and rebound in unison.
thing I have found with Dynamics is that when dyno’ed out, I have never found a pair that actually match that well, they are normally at least 1 click different and the curves are subtly different, also, they seem to ‘wear’ the valving relatively quickly, particularly the slow bump.
For the money they cost, I would go just about anywere else, there are far better options out there at less money, however, you really do need to know what to ask for, AFAIK, very few makers have spent any time at all on the Elise/Exige to get it right, so 99% of the stuff off the shelf will be wrong.
Rate wise, as I said above, this depends very heavily on what tyres you are running, and the type of use the car is for.
The basic logic goes that the stickier the tyre, the more spring you need (to counter the increase in latteral grip and resist additional chassis roll).
For a track-day car that’s still road used and on something like A048R’s, the sort of place I would start is ~400 front and ~550 Rear keeping a sencible ride hight of ~115-125mm. (I hassen to add, this is not what I run! but then mine never see’s much of the road etc.)
This should give good balance and chassis control without taking your fillings out on typical crap roads.
At these sorts of rates, you don’t need much in the way of damper rates, so the ride quality does not suffer drastically. (don’t forget the ARB in all this…)
Having said all that, it really is an individual thing about finnal rates you can get on with, but remeber that springs are cheap, dampers cost money, so it’s important to get them right.
PS. Nitron are looking at doing some 2 ways for the Elise/Exige market, these will be aimed more at race use than street though…
