front height and spring

[restimax]

hi, ;D
the front chassis is always much bottom regarding the others cars some now is 20 mm front and 24 rear, but for having this height I have had to put much thickness behind the spring.
it's correct?
i use oil asso 35, with spring black

Hi,

Wherever I run my car i always run the front ride height 16mm off the ground. No matter what surface. If you run the front too low it will bottom out on landing and bottom out through mid corner as the front will attempt to roll/lean away from the direction of the corner, but will run out of travel and the front of the car will hit the floor causing an understeer effect. Also if it's too low it will not jump properly, it will hit the up face of the jump rather than riding up it and the car will not fly flat through the air.
20mm is quite high for the front of a pred, but it should handle ok, especially if you're running on a bumpy surface but as I say, I use 16mm everywhere and that seems to be about right. 1 Thing you may find is that if you are running the front high and therefore having a large size of spacer above the spring, you are obviously compressing the spring quite hard and therefore the spring may not react the same, when you push the front of the car down it will likely feel over damped and stiff so I always try and run as little spacing as is possible whilst still maintaining suitable tension on the spring and necessary ride height.

P.S. I run 22mm of ride height on the rear.

thanks Tom

thanks, but therefore low do not touch under the chassi when it lands from jump?

the ride height that Tom has sugegsted will mean the chassis touches the ground ocassionally, and probably after big jumps. BUT if the suspension is setup correctly, then this grounding will be "controlled", and not a big "slap" when it lands, so it should not cause too many problems.
