Just out of interest what's the standard spring rates on the vxt?

Good price

Not enough

Do you need the whole CF ARB and setup to compliment these?

375F / 475R IIRC. Plenty for the road IMHO.

Must be valved soft then certainly don't feel like Nitron's on the same spring rates!

CF Nitrons are uber valved, much harder than standard Nitrons even thought the springs are softer. This setup allows you to click right down for comfort or put it in rock hard 'track mode' Great kit

[Bumblebee]

Can someone kindly explain what valving is? As I've heard some people will use hard spring rates for the road with (I presume soft valving) or vise versa. (sorry for going slightly of topic)

Great kit

Just to follow up on this, and how Simon explained it to me (assuming I picked him up correctly), is that they are valved such that the low-speed damping / valving is pretty hard / stiff, but high-speed damping / valving is quite soft, meaning they are relatively stiff as the car rolls and pitches (low-speed movements), but not as stiff on high-speed / frequency movements over poor surfaces, pot holes etc.

Where's Mr Tapscott when you need him? 375/475 is the 'standard' Nitron spring rate, note the OEM Eibachs. There's a chart on here somewhere, I'll have a look. 'Valving' refers to the devices that control the flow of damping oil from one side of the piston to the other and therefore are fundamental to the behaviour of the damper. It may be clearer above to refer to slow bump and fast bump rather than 'low-speed' as it of course is independent of the speed of the car.

With thanks to our Swedish friends (although the chart appears to have vanished on our new improved site) VX220 NA = 234 / 268 lbs/in = 42 / 48 N/mm VX220 Turbo = 275 / 315 lbs/in = 49 / 57 N/mm (estimated value) VX220 Spax kit = 250 / 350 lbs/in = 45 / 62 N/mm VX220 NA Nitron kit = 375/450 lbs/in = 68/ 82 N/mm VX220 Turbo Nitron kit = 375/475 lbs/in = 68/ 86 N/mm VXR = 300 / 340 lbs/in = 54/61 N/mm (estimated value) Oehlins = 350 / 400 lbs/in = 63 / 72 N/mm (estimated value) -------------------------------------------------------------------------------------- S1 Standard = 185 / 220 lbs/in = 33 / 39 N/mm S1 LSS = 228 / 285 lbs/in = 41 / 51 N/mm S2 Standard = 228 / 285 lbs/in = 41 / 51 N/mm S2 LSS = 250 / 325 lbs/in = 45 / 58 N/mm

Thanks for that!
