I'm running a B4 on astroturf - it's a bit unusual in that it's indoors on a hard concrete floor (most unforgiving in crashes!).
I have a fairly standard setup on it - everything is more or less in the middle setting. Silver springs all round, 35wt front, 30wt rear. Outer 2 rows of minispikes removed from the rears, stagger rib yellow fronts. There are sheets of lead under the lipos and on top of the servo.
My two main issues are grip roll (high-speed corners) and on-power understeer (hairpins/low speed corners).
For the grip roll, short of balding my tyres or switching to green minispikes from yellow, I'm thinking of either shortening the rear camberlinks to reduce sidebite mid-corner (where it tends to roll), or else putting a washer or 2 under the rear camberlink ballstud?
Would more weight at the back of the battery dock help?
For the on-power understeer, I know I need more weight up front (no brass bits for me, just chunks of roofing lead), but what else could I do? I went to staggers to reduce grip roll, perhaps go back to minispikes? Richard Lowe commented somewhere that washers under the front camberlink ballstuds would give a little on-power steering, but I presume also take away off-power steering? Would lengthening the front camberlink help?
The car isn't far off, it's just a bit too on edge.
