Last week i fitted the Nitron's. But i have a problem, the riding height is rear 2,5cm higer the oem. When i lower it the springs are loose between the dempers. In front the car can be lower 1,2 mm then the oem riding height. Sorry for my bad english :-)

[fezzasus]

Were they designed for the VX220? The different Elise models have different damper mount points and so have different rear damper heights.

Only elise s1 have a different shocks. Elise s2, exige 340r are all the same Nitron's . I bought them second hand from only had drive 500km (310miles). He was making a race vx220 but it was to expensive so he sold everething. He assurer me that they are the good one I also contact Nitron but it is to fast for a Answer.

what is the open length of the Nitrons? http://www.vx220.org...-length-issues/

 

 

[gertje]

I have see the treat but ther is still no solution?

[fezzasus]

There is a solution, it involves adding a longer eyelet on the suspension. The link was to provide open measurements (395 mm) which might help identifying what's right/wrong with your suspension.

Use helper springs to keep the springs seated when on full droop.

http://www.elise-sho...dels-p-135.html You meen this fezzasus. Yesterday i call to this shop the rear was +\- 430

[gertje]

When you use helper springs the i think you be verry fast at the end of the demper (bumpstop)

No. They won't solve whatever your problem is as the rear mounts aren't replaceable on the VX. Nitron have produced a replacement  part to increase the open length of the dampers, though I'm not sure that is the fix for yours as I've got the 395mm open length NTR's and even at stupidly low ride heights, the springs are not loose let alone at standard ride height.

 

Are you sure your dampers aren't for a K series engined Elise? Only Toyota engined S2 dampers are compatible with the VX.

The problem is i hot them second hand and they came from under a vx 220. He assured me that the Nitron's are the right one

[Exmantaa]

Gertje; what springs are on those NTR's? And post a few pics

[gertje]

Tomorrow i put the bilstein back, and i post a few pic's on it. I think more and more these are not the good one for the vx

[gertje]

the only pic i have these are the front one.

Are you in contact with the bumpstop at the rear ?

Give some détails and pictures.

Give the shocks open lengths, spring rates, etc...

I think you have to tighten the spring to lower the car, not unwind. http://www.sector111...ning_Guide1.pdf

Ronnie was the original owner, who bought the nitrons new.

(before the car crashed, and went to Jim)

Contact Ron, as aks what spring rates his Nitrons came with.

 

[Exmantaa]

Just read the last number on the springs for poundage...

 

(Anything above 500lbs (rear) with the correct longer damper length needs helper springs if you want to ride lowish.)

If you are using such hard springs you will need helper springs. I am guessing you are only using your car on very smooth race tracks? Best regards, Paul
