Setup Tip: High Grip

I thought since I had to change my car a little for this track, I would share the thought behind the changes.

First off, I normally start any track with my normal base setting that I’m very used to driving. For all you KYOSHO guys, that’s my Neo setup, but with 5/5/5, or 5/5/3 diff oil.

After my first run , my car was very reactive. Any little movement of the steering made the car unstable. That normally means on high grip that your front diff oil is too thin. I changed to 10k and it really helped. Normally when you go up in the front, you need to go up in center as well. It will give too much power to the front and just pull the car around. One way to also know if you need to go up in the center is your tire wear. If your front tires are wearing much faster than your rears, you need to go up in the center. I went to 10k in the center as well, I left the rear as I started with 5 and I don’t go higher than that. The diffs is the first change you want to make on high traction, after that you can then tell if anything else needs to be adjusted.

With the high temps and high speeds, I felt my shocks too soft. I changed from 45/30 to 50/35.

Next my front end was still feeling soft. I tried a stiffer spring, but didn’t like the feel. After that I moved my front upper arm up to have a stiffer roll. That felt better than the spring because it only changed the stiffness in the turns, not really on the jumps.

After that I changed front sway bar from 2.3 to 2.5. Again just just help with front end roll. That really help give me a more consistent feel. On high grip and high speed you want front end stability.

Most people change caster right away on high grip. They go to more caster. For me I normally don’t like that. I tried 16 degree in the last practice, I didn’t like the feel. More caster is like moving weight back in the car. For me I like the weight in the front, it just needs to be stiffer.

That’s where I’m at right now. Hope that gives a little light as to the thought process on some setup changes. Thanks for reading and God Bless.

  1. When you raise your front upper arms do you feel that it raises or lowers the roll center?

    With the front arms raised, did you feel that your car had smoother or more responsive steering?

    I’ve asked several pro’s about this and they all seem to have different answers, just wanted to hear your opinion. Thanks and best of luck this week.

  2. Great information, really happy to see you posting this kind of tips. Will definitely help noob like me :). Do post more tips Jared, maybe do video on how you do shock or a full video of you building up a car with commentary (ok I know that would be a huge video)

  3. Hey Jared, thanks for the tips. I’ve been reading this tips over and over again after cnetic. Too bad I cannot join the race. My question is, people told me that shock position in shock tower have something to do with giving the car more grip or less. But I cannot feel any difference, what I only feel is how the car turns. I ran 5/5/3 on loose grip track the other day, but the rear end still slapping in every turn, and the car is unstable on landing from big jumps. What do you suggest? Is it oke if I change to 3/3/3? I mean is it oke to go thinner oil than the normal setup like 5/5/3? Please help, and thank you. You can reply to my email if it is oke with you.

  5. Hi tebo
    Love the blog, really gives an insite into the life of a pro!!
    I have a further question regarding high grip. We run in the uk on a lot of very high traction astro turf tracks due to our crappy weather. Now regarding diffs, how thick oil would be too much. Im currently running 15/15/10 and still feel like the car diffs out under aggressive throttle mid corner. The car seems to spin the inside wheel to much which loses forward drive.

    many thanks colin

    • I’m really not sure. I have never ran on astro before. I would ask the fast guys in your area what they are rubbing, and give that try. Most brands of cars will run similar oils. Sorry I’m not much help
