Can you help me understand why adding a 1mm roll center shim on the bilkeahd clamp would help keep the back in shape in this case? My first instinct would be to add the 1mm shim to the rear to finely adjust the roll center lower and add some grip in the rear. I'm not debating with you just trying to get better at setup
Thx Craig.
No trouble at all
0mm ackerman is kit, 1mm is a bit more mellow particularly mid corner
With the RC's you are right, lowering the front RC with all other thing equal will give more steering, but when we are taking about the upper links the change in height of the RC is very slight whereas the change in camber gain is more noticeable, and its the camber gain on the L setting which can make the car bite mid corner and cause the tail to step out unexpectedly - this is most evident on large tracks (e.g. nitro) with long continuous radius corners.
You're correct on the changes to the rear too, adding that shim will really lock it in but I've never liked the car with 1mm on the rear bulkhead because it just seems to steal corner speed away.
