I was grip rolling lots running no additive. Soon as I started plastering it on for every race, grip roll went. I took some advice from some of the more experienced 1/12th racers in my club, who all said the additive stops you grip rolling. By not running it, the tyres slip then grip hard, causing the grip rolls. It starts off fine, then as the grip comes up during the evening, the roll gets worse. Running additive every race got rid of my grip roll. A high car, or really high walled un-trued tyres will also have it however. if you have taken care of that, plaster on the additive...

A couple of different opinions there I found the beginning of the meet the car was brilliant I was 2nd overall until round 3 when it started biting in and grip rolling I was running less additive so maybe I will try banging loads on and see what it does I will get hold of a spring set as well to try harder springs. I am running the kit o rings as well something I have noticed is that you can not get the front of the car down to 4mm

I want to help if I can but am too lazy to read the whole thread so excuse me if I am repeating things.
I would make sure there is no sloppiness in the grommet department. If the grommets squidge about under cornering load it will cause additional steering and nackker your driving. (chassis flex will do the same thing because of the big distance between servo mounts and suspension mounts.) I am running kit (sstox) tires, green springs on front and mardave pod at rear with no diff. (sstox rear is silly) It feels pretty good. My test driver has a diff in his and raced twice and got first and a second.

I realise it is counter-intuitive, nonetheless when the grip comes up you need the car to be softer. Additionally, the car needs to have smaller diameter tyres to remove some sidewall flex. Try 45mm fronts and 47mm rears.
You can also brush superglue on to the sidewalls of the front tyres to remove some grip, but that should only be in extremely high grip. The glue should be sidewall only, to the top of the sidewall, but not any on the tread of the tyre. I see lots of cars where drivers are going harder and harder on the springs and tyres as the grip comes up, and then having grip-roll. The reason that it works better if you put some additive on is because that softens the tyre. As a rule of thumb, as the grip comes up use softer fronts. If the level of grip locks the rear in, then go to a harder rear. 50 front is too hard for your carpet. Go down to a 45 and see what happens, if necessary go to a 42. IF you can true them down to 47/45 then do so. I do think from your description there is something up with the car, so a rebuild with the instructions in front of you might not go amiss. I've been doing this for 35 years, and mistakes made when building the car are still in my repertoire! HTH |

Cheers for the advise I dont think I have done any thing wrong building the car but there must be something I am doing wrong as I used to get the same problem with the dave the only thing I can not do is true the tyres down as I have no way of doing this I always have to run them out of the box maybe this is the problem i dont know

The latest batches of Contact tyres will be coming in at 45 front and 47-ish rear, so hang in there!

If you run your tyres a bit, they wear down, no need to true ;-) Has anyone at your club got one that they can bring on a race night, or let them take home a set of your tyres to true down for the next meeting?

You'll find the new tyre sizes will be worth it for the handling improvement you'll get.

Grip roll
Take note of what the slowone says, 1/12th guys have loads of experience running foams and fighting grip roll. The smaller the tyres dia. generally you will get less grip roll due the rubber not moving across the tyre as much.
I bit the bullet, trued my tyres, 45.5/46.5, 35 rear 47 front, still run the kit springs, car handles a dream. If you still get it in high grip situations, superglue the front sidewalls and go for a softer spring, trust me it works.
