In my testing the T3 2012 needs to be balanced or it is very hard to drive. Balance mostly comes from springs on the Xray in my testing. I tend to not like the progressive springs, but in lower traction I can see how they could be an asset.

Generally this is what I would try...

2.8 front springs with 400 oil and either 2.4 or 2.2-2.6 progressive rear springs with 350.

I would shim out the top of my front shocks 1mm from the shock tower...this will make the car a bit less aggressive.

I would go back to the 1.2 sway bar in the rear.

I would run more toe in the rear to help forward traction. I would go to 3.5deg.

I would move to the middle hole in the front on the inner camber link.

I would take out the 1mm shim on the inner camber link in the rear.

I would dope less of my front tires so that as the tire heats up it does not over-steer as much. ( I know this one many people do not agree with, but for me this has the absolute biggest affect on how efficient the car feels around the track) ( I think it is better to make the car turn with setup changes rather then full dope, but that is my personal opinion)

BTW- I love the Video...I have watched it like 10 times already very clear and a great shot of the racing.
