Hi there,
I have just fitted a brand new set of gaz gold coilovers to my track car, but i really need help with setting them up, how much damping and height? i run 17inch rims to.
Cheers,
Tim
need help please with gaz coilovers!!

The great thing about coilovers is their adjustability, so you can tweak them to suit a variety of conditions/tracks etc. Impossible to state what you should set them to really.

From my general experience with coil-overs (not specific to Gaz), try to start with the spring seat adjusted to provide equal travel during both the jounce and rebound. That is to say, with the damper in the middle of its stroke. Start with your damping set to minimum and work towards stiffer as you test. Keep raising the damping until you feel you have exceeded optimum, and then back off slightly.
Keep in mind that the exact amount of damping required to achieve what is termed "critically damped" depends entirely upon the stiffness of your springs, and therefore some experimentation will be required. If your springs are too hard or too soft for the mass of the vehicle, no amount of damper adjustment (within the limits of the damper) will achieve critical damping.
If it is necessary that you adjust the ride height then be careful not to excessively reduce the damper travel due to excessively raising or lowering. Excessive lowering can result in the dampers "bottoming out" on the bump stops, and excessive raising can result in a lifted wheel, during cornering (although this is by no means the only cause of a lifted wheel).
