Default Low Grip Setup

I race on an extremely low grip surface.What setup adjustments can I make to improve traction? I drive a Schumacher MI3. I have already lowered my diffs and this has helped a bit, but my car is still has virtually no grip!

Thanks in advance,

different shock oil/ pistons, different tyres, Higher or lower ride height, run a front spool/Locker., change springs.

Please tell us more about what surface you are running on, bumpy asphelt etc....

And what tyres you are running at the moment

and what setup specs you have now

and what motor

1st try more droop all round (lettting the arms drop down more) and run a front spool.

try stiffer front springs, try cleaning the track, try lowering the rear upper inner camber link, try cs 27 on front & cs 22 on rear, make front toe 0Degrees, lengthen the wheel base of the car

Do most of these one at a time trying the car out in between

Spring choice HPI F Gold , R Silver .
Oil Asso F 35-40 , R 30-35
Flow F 2mm , R 2.5mm

if not have control insert , can choice JB Foam insert
& use Trinity Tire tweak 2000 & after use Buggy grip in dirty track ,
in clear track use FX 2 !

Around here we still have a couple of clubs that race on "slippy floor" as we call it in the UK - polished tile/wooden floors in gyms or school halls. Grip is very low - so low that we have to run spiked tyres! Looks very strange to anyone not used to racing in the UK.

We also do our fair share of racing on cold tarmac.

Anyway, what I have found from running on low-grip surfaces is...

- Tyres are crucial - get them right and everything else starts to come together. If the surface is cold, go for a soft compound. If the surface is very dirty, you may even need treads. Additive or even tyre warmers will help to generate a bit more grip at the start of the race, before the tyres get up to their normal working temperature.

- Avoid the temptation to go too soft on the suspension - although in theory it generates more grip, in practice it usually lets the car move around too much, so you get a poor tyre contact patch and poor handling response. A typical medium-grip asphalt setup should be soft enough.

- Run plenty of droop. More wheel travel creates grip for free.

First vacuum the track, then spray with Grape Juice. Let the soda dry and then start on your set up. Dusty black top will have you chasing your tail for ever !!

Where are you by the way ??
