convert nm/mm to lbs

Also

how can you just say that without knowing the MR(ratio between spring and wheel) on the car? it is not the same as an s2 coupe or an urquattro..

200n will be 130nm @ the wheel MR 0.65
150n will be 142@ wheel in front

an s2 coupé has an mcperson strut at the rear also, an mcpherson has approx 0,95 MR

Corner weights are important but the vehicle weight involved doesnt warrant the need for such heavy duty springs. 900lb/ft requires alot of force to compress the spring, and your unlikely to obtain that in a lightened S2. Too stiff will not allow the dampers to operate, which will limit traction. I'm guessing the aim is speed and agility being a trackcar, in which case the compromise of stiffness to avoid bodyroll but good damping ability to allow the wheels to be loaded and pushed into the track surface under cornering.

Why should the dampers not operate when they are valved for this spec?

im estimating 1550kg raceready with about 55%front and 45% weight rear..

and yes the aim is that.

we´ll se what stiffnes it will be after the cornerweighting and some testing on tracks..
