one of the main reasons why ive not touched the suspension on my Z. all previous cars have been modded including my G.
i think the stock Z is at the right height for street driving. anything lower i'd had to slow down. and this car does not like to be driven slow.
go back to stock? or run nismo suspension. those are taller than base also maybe swap with a 2013 z suspension? i think those run a tad taller than the 09-12's.
