Grip Roll on Astro Turf - Anti Roll bar

[mikeyscott]

Took my car out to Titchfield tonight to see how it runs and found it suffering from grip roll. Started to feel better after I change the rear tyres to mini pins - shumacher and fronts are mini spikes at the mo (need wheels for my stagger ribs). It was particularly bad with mini spikes on the rear. ( I will add that the tyres on it now are worn)

Shocks are :
blue spring & 35W on the front
silver spring and 30w on the rear

I have an anti roll bar sat in my box, worth fitting? I got it due to the manual stating that it's a good option part for high grip tracks.

How much would it help to fit it?

have you tried cutting the outer row of spikes off the rear mini spikes and the inner and outer rows on the front mini spikes?

[mikeyscott]

Hi,

Yes the front tyres spikes have been removed ont he outside edge which certainly helped. Nothing has been done to the rear tyres

Since the new 7.5T motor has gone in I'm getting grip roll again. Do I stiffen the car up or change componds on the tyres? Anti roll bar will come off as the track has quite a few bumps in it.

Not sure if it's the right way to go, but I've always softened the car up to reduce grip roll...reduces the grip and allows the body to roll more without taking the whole car over...well that was my logic anyway!

Also, I've just gone from a 10.5 bonded to an 8.5 sintered motor in my x6, with no other changes I'm now getting grip roll...I'm wondering if it's got more to do with my throttle control and cornering speeds than the car setup!!!

Faster motor and heavy handed throttle control...more practice needed for me I reckon...what a shame!!!
