The biggest difference will be the tyres. If still want more then the AE big bore white front spring will be the equivalent to what is on setup sheet.
If still want more then try adding an under servo weight or the C0036 bulkhead weights, although I expect you'll be happy with it once the right tyres and springs are on it! :thumbsup:

Thanks Gaz
Your setups usually fit my driving style well hence why I stole it:blush: just needed a bit more steering and cheers guys have learned a lot today just for this thread round of applause all round!:thumbsup::thumbsup::thumbsup:

Not 'stolen'. That's what it's there for. :)

EFFECTS OF FRONT ROLL CENTER ADJUSTMENT
FRONT UPPER CAMBER LINK - SHOCKTOWER
Upper holes (lower roll center)
• Increases steering into corner • Car is more responsive
Lower holes (higher roll center)
• Decreases steering into corner • Car is less responsive

That's the wrong way round, raising the ballstud lowers the initial RC, gives less initial steering and more on-power.
Lowering the inner ballstud raises the initial RC and increases initial turn-in but reduces exit steering :)

I think you are saying the same thing, higher inner ballstud position lowers roll centre, the guide calls this upper holes based on the car it's referring to.

With any setup parameter there is a sweet spot - any change in any direction away will give a decrease of what it has optimized..... and changing something else may unoptimize what was optimized elsewhere.

Therefore, very much trial and error... every track is different, every 5minute run is different on same track! due to temperature, weather, track wear etc etc etc...

But in a nutshell, have a good general setup starting point & listen to Rich Lowe.. :)

Rich has been a massive help to me over the years. As far as I'm aware, he's never been wrong about my setup changes...

Regarding caster (and I may be wrong, so more technically minded rc legends are allowed to shoot me down) I always thought (and this is going back to my F1 days where it was a good tuning aid) more caster equalled less initial turn in but more agressive exiting corners and the oposite for less caster. If we ever needed more turn in on the F1's we always removed a bit of caster for a touch more bite.

And as far as the roll centre and camber links are concerned, the way Rich said is the way I've always been taught. :)
