Well I've never been a big Avo shock fan, so think its time to look for a better option.

I've always been pleased with the performance of Nitron dampers on Caterham's but they don't appear to be too widely used on Radicals (except for Rob!) what are you all using & if you have changed to another option what are your opinions on the difference they make?

What sort of spring rates have you tried & what handling changes do going softer or harder bring?

Again other than Rob, anybody ditched the Nik link & just upped the spring rates to compensate?

Thanks!

Well I did do you a coffee! What spring rates did you settle on, or is that classified info!

Cheers Rob, if the wife is with me next time you may be in luck for a sarnie!

So considerably harder than the PR6 on the front then, they are listed in the book as a 300lb springs & 350lb on the rear with the Avo's.

If you put harder springs on the front & leave the rears alone you would expect more understeer wouldn't you? With these things is it still roughly true that the softer end will have the more grip?

Did you make any specific requests on the damping arrangement, did you send in your Avo's for them to put on their dyno to see where they were roughly?

So what happens if you increase the spring rates in proportion both front & rear, apart from not handling the bumpy tracks so well, what would you expect with a Radical more or less grip, or as you alluded to earlier is it the more grip from the track the stiffer the springs you can run whilst showing an increase in overall grip?

What do you mean by zero droop, I have heard of it but don't know exactly what it means? Guessing it it means that the length of the spring/damper assembly is the same with the weight of the car on or off it, ie its preloaded to hold the static weight of the car without compressing?

Most informative Rob! So if I do go down the Nitron route think I will go up on the spring rate a little, however from previous experience with them they alway seem to be stiffer than other makes of the same nominal poundage I guess because of the way they are damped?

Did you consider the 3 way adjustables or is that just likely to be too many things to get lost / fiddle with!

So is the Nik link just an anti roll bar or something more complex?

You are a font of knowledge on this subject!

Whilst you are at it, can you tell me what the standard spring rates where on the Prosport, were they Avo's on them, also if they used the Nik link system ?

Guess so Simon, just a bit short of time!

Did your prosport run with Nik links on? I want to get a feel for what spring rates people run with & without them fitted.

Anyone used the Radical supplied Intrax units?
