XRAY - Model racing cars

Hello every body.

I usually use the same springs on my shocks front and rear. Rarely I put the front more hard than rear, but this must be ideal, because the car is more heavy en the rear for the motor. correct?

I never use more hard rear than front. Have this any advantage??

Thank yo very much.

It's all about the balance of your car. If you feel the rear is loose, rund harder springs in the front, if you feel, your car doesn't want to go around the corners do the oposit.
As everything in carsetup, there are (especially on asphalt) some tracks where it works the other way...

Changing springs, and adjusting ride height is a matter of 5 minutes. Try both (on one raceday) and you will feel the difference.
