XRAY - Model racing cars

I too like the front shocks to be heavier in oil because the front takes all the abuse first. If you can keep the front from bottoming out or scrubing then in theroy the rear can get through the jump or bump easier too.

When you have a track with big jumps then you want the shocks to pack more so you would go with a smaller hole on the piston, 1.3.

Now if you have large jumps and a rough track then you may have to meet in the middle, 1.4, and try and tune for both.

Me personaly I like to run the 1.3 pistons where ever I can and I will only go to the 1.4 if the track is to rough and my car is strugling.

So like Rocco said "As a base, run 1.3's all the way around with 35wt in front and 32.5wt in the rear, and adjust to your liking from there.".

Hope this helps.
