Stiffening the Nitrons.

[Mr M]

Didn't have them fitted so no instructions. Easy to do if I got hold of instructions or is it generally better to leave it to a pro. Any advice gratefully received. :-)

easy to fit but I'd leave the set up to the pro's, fit em then do at least 100 mile then get em set up.


I would recommend Ian at TvR if you are up North.

Are you asking about adjusting them or fitting them?

If adjsuting then the following is a good guide:

Front 12 clicks back from completely hard
Rear 14 clicks back from completely hard.

You should see a + and - on the adjuster knob. This knob maybe a little stiff if not adjusted for a while. As you turn it you should feel definate clicks or notches. Wind them up fully + and drop back to the desired setting.

Hope that Helps. Otherwise call Nitron on 01993 849449.

12 front 10 rear seems very soft.

I thought when first reading the OP post he was fitting stiffer springs though it might be he doesn't know how to adjust them like you said.

I'm actually running 475 front springs with 8 from hard and 400 rear springs with 10 from hard, but a standard car with the basic Nitron kit used for general use would be best set at 10-12 front and 12-14 from hard on the rear IMO.

I made the mistake of setting the shocks too hard a while back and all that happens is the car hops and skips rather than absorbs the bumps.

I'm running 600 (17) front and 450 (13) rear, so not that far from your settings

Just had my Nitrons fitted by Nitron today.

They reckon start off at 10 from hard all round - potentially go 5 harder for track days and 2-3 softer if you think 10 is too hard for road use (10 is fine for me but I certainly would not want it any harder for the road).

what spring rates did you go for?

[Mr M]

Cheers all. Will read through this lot. They've been fitted but I'd like to try them a little stiffer and see how I get on. Anyhow , shall read. Ta

Hi there,

I've been getting softer and softer for road use. Used to run 12 from hard on the front and 14 from hard on the rear. I've been getting more and more annoyed with crashing and banging on the sh*te roads here in N.Ireland so I've now got them at 16 from hard at the front and 18 from hard at the rear. So far, handling appears fine, although I haven't pushed it in the wet.

I'm guessing that settings like this will make it more inclined to snake under acceleration and braking but no sign of this yet - may go to a track or test day at the local circuit and spend a day playing around with ride heights and damper settings. Presumably lowering = spring compression = slightly harder spring rate? Anyone have any settings they would like to share?

Cheers,

Al

Resurrecting this thread, anyone care to update their Nitron experience at various settings?
I'm on 10 (from hard) all round and suits me fine for general use.

[spend]

I wouldn't take any notice of other folks settings, just set them fully soft and then start stiffening the damping up until it suits you...

[blackiepaul]

have to agree with spend.

I love mine but I have a set up sheet and I have used different rates depending on what I am using them for. Different rates for the road, different for Silverstone, Zolder, the ring, Cadwell etc etc. Cadwell and the ring were pretty close though.

Are you guys using a tool of somekind to adjust. The adjuster rings on my Nitrons are too hard to turn by my hands. Maybe I'm just not strong enough?

[TVRMARKUB]

I have Nitrons on my Griff 500, personally I'd start off with a stiffer/higher setting say 17f/15r (damper setting) then back em off to suit you.

I find 15f/13r works for me on road but I like the car stiff, and as what's been said above you need to find what suits you.

Nitron should have sent out a adjuster tool, I got one with my new Nitrons for the Sag a few weeks ago with the dampers/springs/fitting kit.

if you had em fitted at a garage they might have nicked it.

and some WD40 sprayed on em also helps.

The damper adjustment is the small blue thumb wheel at the top, if you are refering to the ride hieght adjuster collars under the spring then you need a "C" spanner(or raise wheel off ground and it should turn by hand).
If you damper adjuster wont move, then maybe wrap a rag around it (so you don't damage it) then turn it one click with mole grips/small stilsons etc to free it up then turn by hand.
As for settings, I agree with BlackiePaul we will all have differing view on prefered settings (mine certainly wont be to most peoples taste ). Start really soft and go up 2 clicks at a time until it feels too stiff and back off one click...simples
Oh and the Nitron guide says always adjust from fully hard. Don't forget to count how many clicks to fully hard and write it down somewhere so you know what you started with.

15f/13r from fully soft or fully hard?

go on then big fella, give us them settings/spring rates your running with

from soft, though like hamish says I wind em up from 0 to 24 then back down to 15f from soft 13r from soft.

for track i run em 17f 13r from soft.

that's 7 from hard front 11 from hard rear
