I experienced some excellent air time at the US Indoor Champs this past Thanksgiving. I thought I might actually stake the old rollover into a ceiling tile.

Default Traction roll question?

I have been running my new Rev 4 for a couple of weeks but I cannot fix this problem. I race on a high bite carpet track. Front springs .20, white tweak springs, Red shock spring 60 wt oil, I did try 30 wt, flat chassis, the tweak was checked. Ride hight the same except for the .5mm under the batteries, (which was talked about earlier in the tread). I cannot stop flipping on turns. unless I slow way down. I cannot carry any speed into the turns. Jaco purple fronts, Jaco grey rears. I have tried traction compound on half of the tires, a quarter of the tires and just the edge of the tires. Any help would be greatly appreciated.

A few questions:

1) What size tires are you running front and rear?

2) How much toe are you running?

3) How much camber are you running?

4) How much pre-load do you have on the side springs?

Sorry if you had answered some of that earlier.

Too big tires and too much front toe can play a big role in causing a car to flip in the turns.

How high is the traction? Are you coming off the track with little gumballs on your tires or are your tires EXTREMELY tacky after just one run?

Default Traction rolling

No toe in, -1.5 camber, Tweak springs just touching and I have also tried some preload. After one run the tires are extremly gummy, they need to be cleaned really good after one run.

Default Traction Rolling

I have also tried tires from 2.0 to 1.80. Thanks

2.0 tires are definitely too big. I start my rears at 1.79 for club racing (but you need the lowered pod plates).

What size are your front tires?

Are you rounding the edges of your front and rear tires?

Also, you mention "no toe-in" - does that mean 0-deg toe, or that you are running toe-out? Just wanted to clarify.

What traction compound are you running? How long are you leaving it on and how early are you wiping it off?

Have you tried supergluing the outside edges of the front tires?

Default Taction Roll

O deg toe, 1.77 fronts, I have been as high as 1.85. I just did glue the outside edge of the tires this weekend for the first time but these were brand new Jaco that I did not have time to cut down. I was also flipping with CRC pro cuts. Jack the Gripper tire compound. 20 minutes before racing. I take it off just before the race. I have been wiping the front tires about 5 minutes before racing.

I know it can hurt watching all that rubber go out the window but the car really works well on small tires.

I am starting rears around 1.75 and fronts around 1.68. If you tires are getting really gummy and the car is still flipping with 3mm ride height you are going to need to super glue.
