Quantum shocks - Anybody used them on a 7 ?

[DaveK-S1]

As above, looking to replace some Nitron 1 way adjutable with something a bit more serious for track use, options ar the moment seem to be the ohlins setup or the Quantum Black 2 ways.

Any thoughts on either

thanks

I've not used, and don't know anyone who has used, the Quantums but I am very happy with my Ohlins 2 way adjustable set-up. Have you spoken to Simon at 7 Tips? He can supply Ohlins as well as other brands.

Thanks Shaun, yes i know Simon, we are looking at the viable alternative, Freestyle have used the Quantums successfully on there race cars, just looking for some direct feedback.
There CV for success in racing looks very good, non of the dampers in this price bracket are cheap, so just trying to make the right decision

Freestyle put Quantum's on my CSR. Worked pretty well - got pole position at Spa on 'em - although I'm not sure I had good enough feel for the car to get the best out shocks with that degree of adjustability !

Thanks Fcat, i've tried to get hold of Gary ,but he's gone to ground at the moment

Are yours the 2 way versions on the CSR

Dave, if you're looking for a buyer for the Nitrons let me know?

Stu.

[fcat]

yup, adjustable in compression & rebound

[DaveK-S1]

Thanks fcat

Stu , We will hang on to the Nitrons as they are set up for hillclimbing, so will be an easy change back if the car goes back to doing some speed events, rather than changing spring rates

At the risk of being evicted from the petrol head club, I'm a bit jaundiced on suspension changes and whether it makes meaningful difference going from "good" to "better" kit.

I have been through non-adjustable Bilsteins to 2-way JRZs on my 993; made it worse and took ages to set up for c£5k (from a Porsche specialist...). On my GT3 Cup I now have 3-way Penskes; made it a bit better, but loads of set-up and frankly not sure it made me faster than the standard issue and still not all the way there on the setup - this was a lot more cash.

On my caterham I have the 1-way Nitrons. They were there when it was a road car and we still use them now we race it. We more than hold our own as things stand on the track. So, whilst I have messed around with suspension a lot, I am not convinced it gets you the bang for the buck, plus there is a lot of cost in getting the set-up sorted with testing, ideally a setup expert on hand etc.

Call me a big girl's blouse, I know!

I have now also driven the new Nitron by Aurok http://www.pistonheads.com/xforums/imgs/6.gif

So much better than the standard. They act and feel just like the Ohlins 2 way even if they are less adjustable as a one way.

It has to be the Black Arts for the road/track - the first road chap to try them rang me straight after to say how amazed he was.

Give me a call - fitting 3 way BAD's to a race 7 at Combe in the morning.

[DaveK-S1]

Thanks Simon for the advice.

We have decided in the interim to get the Nitrons upgraded to 3 way adjustable

There's a lot of good sense in this post.

There's no reason that a correctly valved set of non-adjustable dampers can't give an equally good optimal, average setting as a set of fancy three-way adjustables and unless you're carrying your own personal Race Engineer, a good set of correctly valved one-way adjustables give sufficient scope for basic tuning without the risk of getting lost in the vast range of variables that result from multi-adjustable dampers.

Unless you're planning to do a large amount of testing with a race engineer and set-up logs for every circuit you visit, KISS principles apply...

Sam

Yes you are correct, a correctly set up non adj/1way is fine when it's valved properly, the 3 ways will give us the opportunity to get to that ball park.

Testing and race engineer on board already so we should be ok to try and get the setting close

I'll be waiting for your call next year then Dave http://www.pistonheads.com/gassing/imgs/9.gif
