If grip is really low, it might actually be worth trying less camber.

I looked at your setup in RC CREW CHIEF. It's show's your setup is pushing bad from mid to exit corner.

A: I would look at increasing the camber gain for both front and rear.

1- Take out the 1 mm spacer out from the front inner link. You need more roll on the front

2- Raise the rear and upper suspension blocks by 0.5 mm. This will increase the camber gain both front and rear, if traction is low than more camber gain will help. The front will have 0.23 degree of camber gain and the rear will have 0.12 degrees. Originally, your camber gain settings were 0.8 F and 0.7 R.

B: Increase the rear camber by -2.0, the front looks good.

C:Run HPI Silver front and rear. Right now, your front ride stiffness is greater than the rear. I would suggest taking the front shock down to the same hole position as the rear and highly suggest changing the spring to HPI silver.

D: Lower your ride height a little bit, if you can 5.5 front and rear.

E: Add 20 grams of weight up at the front.

Default Setup for Sweeps on Medium Grip Carpet

Here is my current setup on Sweep tires also purchased on 3/7/14 from TQRC Raceway and used that same day. The batch of Sweep tires I used have the translucent white "natural stiff" wheels, I'm not sure if the rubber has changed since I don't use Sweeps too often. This setup is a work in progress and will get much better but it is still very easy to drive.

I want to stress that I am using a Tamiya servo saver, which is equivalent to using the short kit servo horn. A shorter horn makes a big difference in calming the steering down.

Thanks for the setup. I see that you goop your rear tires a lot longer. Are you doing full front sauce and are your front sideways superglued? That was the only way I have been able to calm those tires down.

I didn't use additive yesterday, the track was to dirty.
Just heated to 50°C 10 minutes before.

Thanks for so much tips. I noticed all and will try it in the next days.

I have. In most cases it makes the car easier to drive for me. It kind of smooths out the steering and makes it more constant. I also don't run them with blades. I use the steel outdrives. I just switched back to the spool for now. Can't decide which I like better.

Have you tried Banzai, ApexRC, ToniSport, or RCMart? I currently run the aluminum Arena ones from Rcmarket. But I do have regular plastic backups.

Nope sorry. We haven't started racing outside yet. I'm going to start with a spool outdoors. If it's a small tight and technical track, then I'll try out my diff.

I wouldn't mind trying some of the Reflex stuff in my diff.

I prefer running Gravity RC 2.5 million cst over the spool on my tight twist asphalt track. I found the spool would launch the car hard out of the corners and cause the rear end to lose traction. After switching over to the 2.5 million, the car settled down and became consistent and easier to drive. Highly suggest it for outdoors.
