XRAY - Model racing cars

Hy guys,

What is better Hard Oil/Soft Springs or Soft Oil/Hard Springs ?
I think my Car is going really good. But on the other Side i think the Car is Slow (sluggish) and sometimes i think the Car understeer. I use always Seep EXP Evo 36 Tires but in Hot Conditions the Tires overheat fast.

This is my Setup. I dont know why many Drivers Raise the Upper Deck. I think the Car is going better without raise the Top Deck and less flex. And many Drivers says in Stock is Important to have loose Belts but i think with more thighten the Belts the car goes more forward. I would like more forward traction, more roll less sluggish feeling. And less understeer. But
I hope some Drivers can help me ?

Thx !

I always remember being told (though I forget by who)

'Springs control how much (movement), dampers control how fast'

When I've raised the upper deck it just made the car nicer to drive.

If you want more direct steering and don't want flex, try running the layshaft screws with the steering plate and post and remove the centre post.

Have you tried progressive springs?

Perhaps try softer damping to reduce heat in the tyres with progressive springs etc.

Based on your setup, you will always have a few issues.

1. 1.4 rear bar is too thick. Im assuming you have them setup backwards on the sheet and are running the stock bars. Try a softer front and rear. Most run a 1.3 front and 1.2 rear for asphalt.
2. This tire and car usually likes more camber. At least run 2 - 2.5. front and rear.


I dont think the tires will overheat unless its really hot if set up correctly. We just used this tire and it was 90 degrees outside. No issues with overheating in mod on a tight track with a long straight.

Thank you guys for the Replys.
I will test it soon.

Can someone help me.
With my Setup that i posted in this tread i have understeer. I have test a lot but i have always a little bit understeer.
How i can resolve this ?

Thx

Have you tried any of the suggestions we have made yet?

Based on your setup sheet, I have some suggestion.

1) Roll Center : Move both FF and FR in bottom position of Eccentric Bushing. It will help a lot of under steering.
2) Anti-Roll bar : F 1.3 and R 1.2
3) Front upper shock position : from hole 3 to hole 2
4) Front camber link "Inner" Shim : From 2mm to 1mm

This setting should be come from Alex and Bruno in general. You can modify based on your track condition.

Thank you Guys !

I have try the 1.2 Rollbar in the Rear i think its better.
And i have change the Shock Oil from 550 to 400.
But i think with 550 its more direct.
With the 400 Oil i have more Tire Wear.

I will try to change the Piston to 3 Holes 1.1mm with 350 Oil.
And i will go back to 2000 Rear Diff with 5000 the Rear End its a little bit loose.
With the 2000 Oil i can push more out of the Corner.

I fight always with a little bit understeer. I miss every time more turn in. I think its possible that from the Solid Axle in the Front. I will try a Diff with 1 Million or Putty in.
