Whoa that took some time! Well now that I tested the higher rear roll center I am pleased with the car. It was a quick test and will need further validation, now the car drives more smoothly through corners instead of swing the rear and hook again and also no more twitchy steering. Two birds with one stone.

How many mm did you shim your rear holders?

Raised 1.0mm front-rear and rear-rear holders from 0.5mm (for a total of 1.5mm). Maybe I will raise a bit further while keeping the rear arms level and work on ride height and camber link shims, my intent is to have roll center at ground level during most of the roll motion.
Stock was horrible to say the least, too much steering both entering and exiting turns on asphalt. Today was damp but the car actually had more rear traction than when I raced it the last time (October/November). Felt like it was a bit softer and compliant, instead of a plank.

I have found that 0.5mm in the rear blocks and 0.0 in the front provides a good roll center balance on the 6.2 as well as the yellow sway bar in the front to balance the added front chassis roll.
My 6.2 is really planted and so much easier to drive. more importantly it's faster too.

Are you talking electronics or FDR?
If you are asking about "gearing", it all depends on track layout and size.
In most cases you will use an 86-96 tooth spurs and 47-56 tooth pinions depending on where you run. On a medium sized outdoor track you want to get to ~3.5 to 3.8 FDR but like I said we need more info.
1)motor brand and model
2)track size and layout (including straight length)

Ok, that fits to my experience.
On carpet I tend to use 0.5 under front and rear blocks and put the front rollcenter even a little higher by lowering the inner camberlink mount by 1mm.
Otherwise the rear started kicking ...

But on asphalt I'd also go the other way.

I went the other route, raised the front blocks but lowered roll center by camber link angle without sway bar changes, raised the rear blocks a bit also. If you see the wheel rate (spring and sway bar stiffness at the wheel) they are close front and rear with non-stock springs (don't know which springs are these, some sort of gold on the front and silver on the rear, they have quite a lot of wiggle on the shock body).

Here's the setup on non conventional setup sheet.
