in cali i believe you are required to have your car 4" off the ground, if it is that high off the ground and you have trouble getting in then tell the super or the owner--

but in all honesty, unless your are auto-x'ing or circuit racing you probably wont hit the limits of a near stock suspension.. on my GS-R i've only rubbed once and that was because i swerved right after a very long curve to avoid a very large pothole., and then it was barely.

as for launching... you shouldnt be doing it on a daily basis anyway...

to tell you the truth you might enjoy having the comfort of a higher ride height vs the unused potential of a coil-over system.

 

but i like taking turns realy fast
