Re: mtx set up
 

If I were you, i'd use a front diff on those track conditions........
small, tight and technical, no grip..... requires late braking on those corners.
Then i'd start again with the basic set-up from Mugens manual, and start dialing whatever correction the car needs on a one to one problem basis.
It is imposible to give you particular set-up that will work like magic...every track has it's mysterys that have to be found.

AFM,
Well said, you took the words rite out of my mouth.

:tire:

i run at a tight technical track. try this setup:

front diff - 50000 oil
rear diff - 50000 oil

camber
front = -2
rear = -4

droop
front = 2
rear = 6

toe
front = .5
rear = -2 (add one if the track is loose)

swaybar
front = flat
rear = all the way to the end of rod

try 37 shore tire all the way around and put 35 in the rear only if the track gets more loose.

good luck and update me if this works :)

i forgot the ride height
front and rear = 5
do 5.5 ride height when the track gets more loose

let me know how your car reacts after doing this setup and you can do more changes from there.

thanks for the info
 

i set it up to spec with the mugen sheet i got online. i have to get the parts to assemble my front diff and then i will try it. so .5 toe in the front is wnough huh, i'll try it, i always thought it was 1-2 deg? any way if the weather permits i will take my newly tuned mtx out to give some a$$ kickin on sunday i will keep all this info close by.

At the weekend we suffered a lot of traction roll (rear end) due to the high grip and high temps.

We tried a lot of different set ups during the weekend to try cure it but it never completely went away.

In the end up we were running the following set up which seemed to help the most.

Rear:

40 shore tires
Purple springs
30wgt oil
Rear Pistons 2 hole 1.1mm
Rear Diff 30k Mugen Diff Oil
Rear anti-sway bar standard setting
shocks in top holes
5deg camber on rear wheels
3-4 deg toe-in
A blocks

Front:

42 shore tires
Light blue Springs
30wgt oil
Pistons 1 hole 1.3mm
Solid Front Axle
Anti-Sway set hardest
Shocks in top holes
3.5deg camber
2deg toe-out
0 caster

Traction roll was still a problem. Any idea what we could try to get it cured as the next track will be the same conditions. hardening the car up made it worse.

Re: Robbie
 

Have you tried C blocks in the rear?

Re: Re: Robbie
 

Yeah, I tried the C blocks once and they didnt help either. Thinking about lowering the front upper wishbones. Guess it will take time to get acquainted with the car. Only had it on the track for 3 meetings.

Y dont u try overstear setting. Set d car hard at rear and soft at front. Hope this will help. Regard.

Yeah. I did run slight overdrive. used the Serpent 23T front side pulley. My teamdriver ran the 16/19 conversion but the teeth on the pulleys sharpened after some running and he had to remove it. They seem very poor quality for kawahara parts. Think I will get some plastic ones made.

How about lessening the rear toe?

1.5 or 2 degrees should do.

Kawahara Tires
 

Hi guys

Can anyone tell me where I can buy 1/10th Kawahara tires from, I'd like to try them but don't know anywhere that stocks them.

Thanks

Re: Robbie
 

try 56 or 57 mm size tires thats what they run last nats at ohio

If you still traction roll with smaller tires, try gluing the sidewalls.
