Using different rollout for different tracks?

Using different rollout for different tracks?
My question is this. I race on a tight 56x32 carpet track, brand new ozite, about a month old. Each week the track changes. I've been trying to figure out what should I be using for rollout. I've driving a xxx-s, monster stock, my foams are 58-60 mm depending on what set I use. I've been any where from a .94 to .87 and everyone seems to have more pull through the corners. Straightaway speed I can hang, but corner speed I just don't seem to have it.
I feel I've got a pretty good handle on the set up making gains in that area. Not sure what I should be at for rollout. I'm running 767 brushes, with red/red springs.
Any ideas on what is a good start I'd appreciate it.

Roll out for a monster will be in the region of 26mm +/- 1mm depending on track size (carpet indoor).
The problem your stating sounds more like a suspension issue though, i would usually say loseing alot of ground though the infield due to bogging down would be because your scrubbing to much speed in the corners.
No dought your car is very stable and quiet easy to drive, just not as quick as the front runners through the infield ??
Try harder springs or possibly a roll center alteration to reduce roll and see how that feels

Try different pinion, and measure your laptime. Sometimes smaller pinion can give you faster acceleration out of corner and better lap time.

The rule of thumb I was taught by veterans and sponsored drivers alike was to gear your car so It does not wind out by the end of the straight away and not too under powered at the same point.
If your car sound like it has more rpms to use then it may need a smaller pinion.
Smaller tracks, use smaller pinions to get up and get 'er done. Longer tracks could use larger pinions to reach the higher speeds.
