I'm still fighting with this incredible oversteer of my car. It happens at high speed but also at low speed.
My car has:
Front tyres: Jaco black, no liquid for grip, diameter: 41,5
Back tires: Jaco yellow, full liquid for grip, diameter:44
Front springs hard
Side and center spring blue
The center spring was checked by a "pro".
What could I do else?

What surface are you racing on
How are the other 12th scales at your track coping with this issue

correct no rear grip, but why?
it is a high grip carpet.
no other car has this problem.
allthough generally the asso s seem to have more grip in the front then the other e.g. yokomos
where to look for my error?

Have you posted a pic of your car yet ?
Might be something obvious
Also
Have a look at this new On-Point video from Robert Krens
It is very informative

Have the same problem too. Extreme front grip, using 30 sh rear(full dope), 35/37(less han 25% dope). Also a little higher ride height in front. Springs: blue center/oil 25wt, speedm. 18 or 20 side, green spooge. Today I tried spacing lower arm 1mm, which calmed the steering down. Using toe-in also. Try spacing lower arm next time you run.

No grip on a high grip surface, suggest this is a build issue

Great video, thank you! After checking my car I found no tweaks, but the center pivot was not free! So I corrected it now and hope that this will solve some of my problems!
Oddski what do you mean by spacing the lower arm? ( sorry my english is not very good )

Yes I guess it is a built issue!

It is fairly wide, but I'd add 1mm if the car has too much steering, also space the top arm in by 2mm - although you will need to run either no brace, or the old R5/5.1 brace.

Hi,
I'm brand spankin' new to 12th scale after 16 years in other aspects of surface r/c. Chose the 12r5.2. Initally, I'm having issues with it "stopping" at corner apex and then turning. Very similar to too much front traction. However, I dont have the rear traction issue. I only use 1/2 to 3/4 rear dope. Being that I'm new to the class, I just threw the kitchen sink at it. I ended up with .24 front springs and 0 degrees front upper arm position. 1 degree neg camber. 0-.25 degree front toe out. I also made the front track width as narrow as possible. No shims on axle inside of tire. 3 shims on outside of tire to take up slack. I went with 13# rear side springs and blue center with 17.5wt oil. (bumpy track). I gained 2 tenths instantly. Im still learning roll out and what not but the car is about 25 grams heavy. Any thoughts? I'm using a 1s hobbywing. ko 411 rx, savox servo, fantom 100c 6500 lipo, revtec motor (reedy on the way). Car balances perfect within a gram side x side with no additional weight. but overall its a pig.

But what about the length ( with ) of the upper arm? It can be adjusted, but at what setting?
Thanks

After watching the video on here, I decided to break the car down. I went to
Lowes and grabbed a piece of marble tile as its about as flat as you can get. It was amazing what a nice flat surface can do. I should have the car back together for tonight. Im going to put 27.5 in the center shock and go up from there.. I have all the front springs available and all the center springs coming from amain. They should be here friday.
