Well, after a little fiddling around in the garage I have discovered that if I wind the adjuster down, compressing the spring and a little adjusting of the wishbones with a jack it looks like it's going to fit. Of course winding the spring down makes more clearance above the adjuster, more top body exposed.

 

Had to stop to get the tea for the wife but will finish it later and let y'all know.

 

Whats the effect of compressing the spring? Lower or higher ride hight? I always get confused at this point!

 

p.s. Bit disappointed Scuffers hasn't come on to tell us we're all stupid and haven't got a clue

Higher the ride height.

 I knew it was not right after 1 trackday but everyone else did nothing but rave about them so rather than start a fight I just sorted it myself and learned a bit along the way. People were brainwashed in the 1st place not because a potential problem was found.

 

 

 

Yeah I remember you bought the Hoffy spec ones a few months before I did and I probably owe the fact that you must have fed the issue back that I got a different spec to yours....  I certainly did rave about mine but that mine had no issues and were very capable shocks and saw me well for two seasons before I went over to 46's.

I would stress there was nothing wrong with the dampers it was just they should have had helpers or tenders to compensate for hard springs and longer travel (thinking of it like that, it's not just more droop but also longer travel)

[Crabash]

To a point I agree with you. If you know what you are looking at and are aware of a problem it should be investigated and corrected. My point is that most (including me) were only not aware but also never experienced any problem. You felt that things were not right when on track, I would wager that over 50% of Nitron equipped VXs never go near a track so most are now trying to fix a problem that doesn't really exist for them hence my "bandwagon" comment

 

 

I agree either not being used in anger or softer setup than mine for instance would most likely never even notice any adverse effects.

However I personally like to figure stuff out, I listened to so called experts when I 1st got the car, being new to this type of car although I messed with cars in general for 30 odd years.

I now know I was wrong, anyone trying to sell something has an agenda, nothing wrong with that, it's the way of the world.

I trust me,  and very few others with my car, certainly a few of the specialists I would not let near my car.

Thought they specced the wrong length tube for your shock, or spring or something as your helper was constantly coil bound on the rears no....? 

 

Sure it was something like that....

[Crabash]

No there were no helpers, was advised it did not need them, hence ended up having to run 135mm on rear or have a loose spring on full droop, I compromised and went for 130mm but this caused a bouncing/knocking under heavy braking on bumpy surface due to weight transfer lifting back enough to leave spring with no weight on it and hence no downward force on wheel.

My rear helpers were coil bound so perhaps you were thinking of mine?

If the dampers had enough droop built in from the start we would have always needed helpers or tenders, the sort of weight of spring we use meant they were not compressed very much when stood on the ground therefor it didn't take much droop to unseat the spring. In my case running below 135mm meant the spring was not pinched at full droop and would even hear it becoming unseated in bumpy heavy breaking zones.

Not a prob if you don't have much droop

 

well springs generally come in 1" lengths , ideally there would be an optimum spring that with preload is the perfect length for a VX , but everyone runs different ride heights.

[P11 COV]

So one rear Nitron in situ 

 

Had to wind down the adjusters quite a bit so it bit concerned about where the ride hight will be. Also it's still a very close fit.

Only one way to find out...

I can only to be bothered to do one corner a night - its too cold out there! May have it ready to run at the weekend if I can be arsed     

 

Then I need to get it over to Matt Bentley to set the ride height properly.

[VXT Tim]

So at max droop they foul?

[P11 COV]

Hmmm.....always make makes my brain hurt this.

 

They foul when the top adjusters are higher i.e. when the spring is less compressed. So I guess yes it will foul when on full droop if the spring is uncompressed. As it is now not quite...just.  I think.

Thing is if the ride height is too high when you wind them down like so then lowering it will put you back in the position of having contact, really need it to be about right or lower as you have them set at the min.

I know that feeling, went to garage tonight to sort the piles off parts I have to sell, stood looking at it for 5 mins and thought fook this it's too cold, I'll go for a coffee.

[GeorgeBC]

Be interesting to see what Matt bentley says. If this is another genuine problem it will be interesting to see if they care enough to sort it for our small market. Anyone else feel you are doomed as soon as you change Vx shocks?

[Bargi]

just a thought, but see what Nitron say?

[fezzasus]

I'm willing to bet they're 46 mm springs not 40. When I got my brackets from them they were for the 46mm shocks. Makes sense to only carry one design, until issues like this happen...

[P11 COV]

Car is back on all fours and seems to work ok. Ride Hieght looks roughly correct. will get Matt to do it properly soon. It'll be interesting to see if there are any witness marks of rubbing/scraping of the rear helpers.

Not so sure about that to be honest. As far as I know on coilover type suspension they would use a set spring diameter for said vehicle. I don't think the spring size is governed by the shock size.

I.e. springs come in standard diameters unless you special order, 1.9", 2.0", 2.25", 2.5". I believe it's 2.25" for the vx regardless of 40 or 46 dampers. Westfield use 1.9" for space restrictions, or they did in2001 when I built one.

However Faulkners do make ref to helpers not all being exact diameter due to requirements and constraints of some helpers on 1.9" and 2" springs.
