Got nitrons fitted last week to the car.

Half out of necessity since front suspension went...so thought it would help resale, etc.

Anyway, am I write in thinking it's a bit lower now ? seems to be grounding on pavements parking that it wasn't before.

Also, it's bloody hard! I mean I'm sure its great for the track, but on suffolk back roads it's pretty ridiculously hard... and tends to throw the car about a bit...feel like I'm in that 80s show automan.

I know they are adjustable, but don't really want to just start farting about changing settings.

I take it though if I just give them all a turn (anticlockwise?) that should make it softer though ?

Had a lot of hassle with Nitrons fitted to Griff and eventually went to Joospeed - great now. Guy at Nitron is also very helpful if you call him.

The ride height is probably best left to someone with experience but you can soften the ride by turning the adjuster anti-clockwise. If you do this I suggest you spend an extra 2 minutes and wind them fully clockwise to start with (fully hard) and then count the clicks as you turn anti-clockwise. This ensures they are set evenly as each shock may well have a different number of clicks available. Try setting the rear shocks 2 - 4 clicks softer than the front for a bit more comfort. HTH.

Stu - I had Nitrons fitted as part of the purchase of mine (3 weeks ago), and indeed, the car does sit lower. I have also had the experience of a generally "harder" ride with the Nitrons fitted (certainly more so than the 5/6 other cars I test drove), but the car seems to be more "planted" on smaller country roads and sticks to the tarmac confidently.

Am hopefully getting geometry re-checked soon and may have a word with the dealer about Nitron settings then.

They can be a bit hard for normal road use if the damping is wound up too high. I started off with 8 clicks from maximum and ended up at 18 click from maximum, before the road ride was acceptable. IMHO that is why you pay so much for them so you can adjust them to suit you & the roads you drive on.

well, its good to know it can be made softer.

They are mental hard at the moment. Last night on some country roads (good surface but undulating a bit) I spent more time airborne than I ever have on the blade...far far too hard...sounded like a speed boat on acceleration as it jumped 'in and out' of the road! :-)

Nick is that 18 front and rear ?

do I need to take wheels off to get at them ? and do I do it by hand or with a tool ?

sounds like a call to power and/or nitron could be useful too, but I often find I get as good or better advice on here! :-)

18 Front and rear. No special tools required just long arms and strong fingers! Wheels can stay on fronts are eaiser with steering on full lock, rear ones are more eaisly accessable as they are fitted inverted.

ah... so fronts have adjust at bottom, rears at the top ?

and I adjust clockwise for softer ? that is I screw away front the strut ? so putting less tension on spring ? or are the threads backwards ?

No other way around front's at the top rear at the bottom.

Anti-Clockwise is softer.

Just to make sure there's no confusion here - the adjusters to stiffen/soften the shocks are the little "knob" at the top of the shock. They have a "+" and "-" marked on them. It sounds like you're talking about the spring seat which adjusts the ride height.

ah right... yeh they sound like they are exactly the same as the ones on my blade then.

yeh..don't want to be messing with ride height.

that explains why they work the other way round from what I thought too.. i.e. anti clockwise will give more room for oil and hence softer. cool. think I understand now... I shall have a go tonight. ta

Tried maximum soft on rears & +2 on fronts, but spun off the road in 2nd gear / 35 mph trying to avoid fella who had pulled out in front. Expensive mistake that (assuming settings aided the spin).

oh well.. thanks for making me nervous!!!

harder the suspension at the back, compared to the front, the more oversteer right enough, so that's not the way I'd have done it...

planning to have front slightly firmer than the rear... was the tusc not tail happy enuf for you ??

Full soft may well be dangerous, on the Nitrons I had on the Noble if you ran them at full soft it was underdamped so if it went it was very, very difficult to catch.

You really need to speak to jools, or better still book a day with andrew walsh on a carlimits.com day and ask him to show you the circle excercises to get maximum mechanical grip from your car. Once you know the excercise you can go to a corner and get your car sorted, there will be a plateau where grip is good and you can choose which end of the plateau you want to be at, the good grip and progressive breakaway or the bit more grip but snappier. Only £150 for the day and you'll learn loads about your car and how it reacts beyond the levels of grip.

I put them full soft at back, 1 click from soft front.

It's like a different car! no more speedboating... rides excellent over bumps. It's more difficult to get the tail out now which is a pity and I suppose it'll come out quicker when it does (though it was still controllable when I played tonight).

So I'm gonna stick with that for now. As Joolz said in his other post...it's a personal thing so he's not gonna be able to help.. the only person that can set it up for me.. is me.

They were at 11 clicks front, 10 clicks from soft back, so its a big big difference. I may stiffen it up a bit and see what it's like, but it so far feels great the way it is. If I go on a track day, then I'll stiffen it for that.

Sounds good. Always set so many clicks from hard tho' as if yours are anything like mine, they will have a different no. of clicks each. Mine have 5 fewer clicks on the rear shocks so setting from soft would mean the rears are set harder than the front - not ideal.

ok.. but why is that any better than setting from soft ?

arn't you assuming they are all 'the same' when set to hard ? is this any more likely to be an accurate postulate than that they are 'the same' when set to soft ?

They are all the same when set at fully hard. It is a needle and jet system and at fully hard the needle is firmly in the jet. Each click is then a consistent step softer.

Guy Evans at Nitron explained this to me.
