I fitted my Nitrons in what i thought was the 'conventional' manner.





The word is that it is better to fit them inverted to reduce unsprung weight.
My question is, do you think the benefits are that much for me to go to the trouble of refitting them now?

I also think as they are it will be easier to set my ride hieght.

Inverted is the way they are 'meant' to be on TVRs. Certainly with Cerbs that is.

Makes it easier to adjust damping.

They could have turned the stickers the other way up to give me a clue laugh

Do yours have independent adjusters, looks that way in one pic but not the other?

I spent extra to have 3-wayson the rear so i can fine tune the low speed damping to optimise my drag race launches.
Better be worth it because thay werent cheap

I certainly wouldn't change them now they are on the car.

I put my nitrons on upside down on my cerb, but have changed them because I suspect they are less limiting to travel the right way up.

The only reason to fit inverted is to reduce unsprung weight which isn't all that much...and as you only go in straight lines it wont affect you wink

being seriuos for a moment, doesn't fitting them inverted cause issues with dirt and wear?

Mine were fitted by Dulfords and they have the adjusters at the top (as Richard helped develop Nitron for TVR's i think i'll keep them this way around)

Well even though I am the one that got on my high horse on your other thread and said they should be put on upside down I have put them on the way you have them there! hehe Reason being it is easier for me to adjust them that way. If I was racing the car then maybe it might make a difference but for my sedate pootling round country lanes I can't see it really making that much difference.

I was told to mount my GAZ damners inverted to reduce ware and tair on the seals and if there was a failure its better to have them inverted, but I think the dirt will get in on top of the piston boady and not do it any good but most if not all road cars have the dampners inverted, just doesnt look cool.

DBv8, those look the biz, im hoping you will be going out on some of south cumbria runs when the car is on the road, just wondering if you have any footage following me in my SEAC a wee while ago.

Per the Nitron site "These shocks are designed to run inverted for reduced unsprung mass and therefore optimum performance".

I'm not sure that can be true as I would have thought the seals will have the weight of the car behind them when the dampers are active. I can't see gravity having any effect when that happens, they will spew the oil at at each bounce whichever way up they are.

I will be out and about putting miles on the engine as soon as i can.
When you say a wee while are we talking about 2 years? Thats a lot of footage to check through but i will have a look. What colour is your SEAC?

I rang Nitrons earlier this week and the engineer effectively said it really doesnt make any difference so I fitted them the same as on yours so I can adjust them easier

Thanks, as much as i had thought. The shox and springs are relatively light anyway so in the whole scheme of things the difference to unsprung weight must be slight.
They are staying as thay are for this year at least.
