Hold tight.

p.s Steve, stop editing my stuff.

Andrew, you cant get set up specs from those manuals that the drivers used do you really think nme would have made them public knowledge? Thats a bit like maclaren f1 giving out there chassis spec to the public you pleb!

[quote="Guest]below are the settings for a group a nme tarmac rally car
pretty useless really for a road car but interesting reading none the less!
you need to bare in mind that the nme car is using upside down proflex dampers which are a fantastic bit of kit so unless you have all of the below then don't try it with these settings
I personally found these settings were no good for circuit use, as they made the car far too twitchy with very similar settings
much better to slightly radicalise ALL the stock Nissan settings as that will benefit the majority of drivers much more

It's of bobs forum, the best bit is some of it is wrong as I had a mod change a few details before it was stolen from here..........now the fun will be if I ever tell people what was changed.............so maybe someone is not as intelligent as they think!

and I have traced Steve Pratt , he never had the setup docs for the suspension but he did have some EPROM chips from the ecus, which are now in my little hands.

I've updated the section on the springs. Sorry for the delay.

Please remember when looking at suspension design you need to consider the package.

I'm still coming back to the interplay between the ride height, spring rate, ARB rate and damper rate to understand what the NME engineers were trying to achieve.
