Extra Low
This includes a shorter spring and shock absorber combination. We only recommend the "Extra Low" option for those who want to go very low. We do not recommend this for serious track vehicles unless you really know how to set up the suspension around it.

Custom spring rates
The standard spring rates are a good combination, but if you want a specific spring rate that is possible. Contact us for the possibilities.
