springs in the spax kit are rated 250 at the front, and 350 at the rear. I am not sure if those numbers refers to kg or pounds or are just a ref. code...

[dude]

i measured the original n/a springs and got this. front 42 N/mm rear 48 N/mm i am changing to front 48 N/mm rear 60 N/mm

[Steve Crisp]

Hi Dude, So according to your measurements the NA is: - Front 42 N/mm = 42 x 5.588 = 234 lbs/in Rear 48 N/mm = 48 x 5.588 = 268 lbs/in Your 60 N/mm = 60 x 5.588 = 335 lbs/in All looking good! Steve

[Steve Crisp]

The story so far.... VX220 NA = 234 / 268 lbs/in = 42 / 48 N/mm VX220 Turbo = / lbs/in = VX220 Spax kit = 250 / 350 lbs/in = 45 / 62 N/mm VX220 Nitron kit = / lbs/in = 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

[dude]

the S2 LSS. is that L=lotus S=sport S=suspension?.

[Ducati996Senna]

For what its worth I was told by a suspension specialist that the VXT springs are softer.

[jaggeler]

fantastic information!!! In the german forum nobody has answered my question about the spring rates there seems to be more interest in bigger wheels yesterday I bought a "Wilbers" suspension at the german ebay do you know Wilbers? Udo

Yes, this forum is definately more technical. They look fantastic, what did you pay? I bought my Eibach Sport-Kit on the german Ebay for €149. Looks better, but I do not know yet how they affect the handling.

[jaggeler]

Hello! Are there any news? Best regards from rainy Germany, Udo

[clipping_point]

Any news on the spring rates for the Nitrons?

[barrybethel]

I had my nitron n/a kit tested before they were fitted. The fronts are 375lbs/in The rears are 475lbs/in Perhaps people can see now why I always whinge about how they are too hard for the road! Anyone wanting nitrons please note - you can specify them with whatever spring rate you want. I just ordered the vx220 n/a kit and that is what I got.

[barrybethel]

By the way does anyone know what the vxr spring rates are? Standard and Oehlins?

[stevevx220]

Perhaps people can see now why I always whinge about how they are too hard for the road!

Mine feels a bit harder but nothing like yours Barry

Where abouts are you ? maybe we could meet up and compare?

[barrybethel]

CP remember those figures I posted are for the nitron n/a kit. I think I have read the rear springs on the nitron vxturbo kit are a bit harder still. Steve I live in Nottingham if that's any good to you. I'd be happy to do a comparison.

[clipping_point]

VX220 NA = 234 / 268 lbs/in = 42 / 48 N/mm

VX220 Turbo = / lbs/in =

VX220 Spax kit = 250 / 350 lbs/in = 45 / 62 N/mm

VX220 NA Nitron kit = 375/475 lbs/in = 68/ 86 N/mm

VX220 Turbo Nitron kit = lbs/in =

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


Anyone??

[garyk220]

VX220 NA = 234 / 268 lbs/in = 42 / 48 N/mm

VX220 Turbo = / lbs/in =

VX220 Spax kit = 250 / 350 lbs/in = 45 / 62 N/mm

VX220 NA Nitron kit = 375/475 lbs/in = 68/ 86 N/mm

VX220 Turbo Nitron kit = lbs/in =

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


Anyone??

CP, the following estimates are based on comments in previous messages from Stu Harris.

VXT +17% (NA)
VXR +7% (VXT)
Oehlins +25% (VXT)

VXT 275 / 315
VXR 300 / 340
Oehlins 350 / 400

So the Nitron springs are are 10-20% stiffer than Oehlins.

PS These are estimates only, it would be good to have them measured accurately.
