I noticed over the other side (Lotus 7 club) a chat about Nitron shocks absorbers that has confused me completely. Me.. I have Avo's with Freestyle springs set up (plus Freestyle adjustable front and rear arbs), very happy, very adjustable (for my liking anyway - 95% road use), never leaked or fallen apart as been reported in the past. Just wondering what every one is running? Nitron comes across as the sexy upgrade option, but is it really? It is a mind field out there with so many makes. Nitrons, Nitrons by Meteor, Bilsteins (I believe Factory use, hint), Penske, Quantum, Ohlins, Bad, Avo and springs...we have Eibach, Suplex, Faukner, plus I expect there are many more, different settings, & spring rates ahhhh?

So please spill the beans, spec used, likes, dislikes, road or for track prefer, settings, spring rates and please relate to tyres using as that is a fifth dimension that needs to be considered maybe and I guess yor complete wheel alignment set up while we are at it smile

There are lots of company's selling many different makes of Dampers for 7's, The problem is because the weight or the lack of it of a 7 the valving has to be specific for our cars its no go just buying a set of Nitrons , BAD, Penske, Ohlins etc if they are not valved correctly. Then you have to establish who do you trust to set the valving and advise on spring rates ?. I bought mine from Simon at Meteor Motorsport because he races what he sell's and usually wins his class so thats good enough for me.

Suspensions are so personal,true they have to be valved correctly, and then adjustable for application, Simon at Meteor and Penske UK did a 1st class job with proper service on a set of Penske 3 ways that transformed my car, a setting for every occasion and assistance from both camps are very impressive, custom built and checked by Penske UK and then by Simon before they shipped. Springs by Suplex, made in Sweden and sold by others that brand them as their own.buy the very best you can,buy it once,to put it into perspective the last track day at brands started dry and my settings were mid way the car was a dream it went very wet and then the car became the usual high powered caterham handful,I softened everything off and it was again a delight, like it was in the dry I could not believe the change.

Another thumbs up for Penske here.
I spoke to Penske U.K. engineer Richard Scott a few years ago, about building me a set for the Caterham, and I found him to be a nice knowledgeable chap to deal with.
I still haven´t got to the stage where I need the dampers, as I want to weigh the car when it´s finished, but I have recently done quite a bit of work on my motorbike, and needed a very special "pull" shock, so I thought I´d give them a try.
Richard came up with the goods, and had one built for me, specially valved for my weight, and with the correct spring.
It also dropped at my door in Spain, in the quoted three weeks.
The quality of the shock is just beautiful, right down to the swivel banjo connections for the reservoir hose.
The transformation, even though I still have to mess about with settings, is beyond words!
Penske dampers are also rebuild able, (mine came with a detailed technical manual, and dyno test sheet) so they´re the only ones you´ll ever need to buy IMO.
In short, I´m a very happy customer who doesn´t need to look elsewhere when it comes to getting some suspenders for my mistress smile

I never got on very well with the Freestyle AVOs. When trying to understand them on track they seemed to stay bouncy for a large part of the adjustment range and then go hard almost immediately.

This was on a track day with (obviously) no timing or data, so I had not idea which of bouncy or firm was actually quicker!

Its not just the Times,ive raced and rallied cars and raced bikes,middling skill lots of offs but ive now learnt good handling just makes getting to ur personal limits so much easier,you can press on and know the car is consistant, conditions change alter the settings not your driving.even road driving is just so much more a pleasure,more complient softer more grip easier to 'catch' on the limit,
