I bought my 3.1 off a mate because they're so hard to find in retail, he's a bit of a nerd when it comes to setups of 12th scale. (I'm typically a touring car guy)
I feel I've got tires sorted from running various brands I think I finally know what does and doesn't work at my local.

Some advice needed on setups if anyone has some answers.
1. What is the best way to check toe without forking out for a setup system
2. My car seems to push heavily and be a little dull on steering mid to exit.
3. Ride out adjusters in the front, does anyone run shims above the springs?

Thanks gurus

I usually disconnect the rear pod as a whole and just balance the main plate only. Then once the main plate is balanced, I reconnect the rear pod. There's much debate on whether or not to balance the rear pod, but most people don't. I use to, but now I figure it's not worth it.

I would look at moving the lower pin to the middle hole with 0 mm upper blocks. This will raise your roll center and reduce the amount of camber gain in the corners, and this should smooth out the front end. However, as I said, this is all dependent on the surface your racing on. Then if you like, try and use a 0.5 mm upper block as this will raise the roll center slightly and reduce camber gain but at smaller increments. Larger changes in roll center and camber gain occurs at the lower arm pin location, whereas the upper blocks are slightly less and are generally used for fine tuning.

Front toe out is good - A setup station is important to have IMO. Every little detail counts.

What is you're full setup?

Once we know that we can help you out further.

Yokomo has one http://www.rcmxstore.com/index.php?m...ducts_id=27059

Kyosho has one - http://www.rcmxstore.com/index.php?m...ducts_id=28355

Xray has one http://www.rcmxstore.com/index.php?m...ducts_id=22913

2. What's your setup?
Look at moving the steering crank system more forward.

3. What do you mean?

I think I've found a few issues I did wrong, I'll work on fixing these up and I'll go from there.

There are many drivers who's skills are close to Naoto's.

I would say this young kid - 江袋 兎々. He's fast, but not as fast as Naoto. But, he has a lot of years ahead of him and Naoya will probably be his mechanic in the coming years...

Issue now is after so many bumps and learning the setup the ball diff is a little sad.

Im going to strip and clean it and sand the plates.

Question is, is there any advantage to putting 16 balls in instead of the stock 8?

Also is it normal that as the rear tyres wear down to almost if not the same size as the front the car becomes very very taily?

I end up just throwing on brand new rears and the car goes pretty well again.

Compared to a fellow racers xray the yokomo ball diff just feels a bit more notchy.

Also are the any other chassis adjustments to assist in mid to exit corner rear grip? other then throttle modulation?
