I'm sorry awbdart,,
but nope they aint,
if you are running enough hp to upgrade over ss springs
money being money,, caltracks is $1.100-1.300.00 $
you can sneak set of ladders undr a car for far less
250$ for the bars and slider and keep stock springs!!!
and be better than cals
that is a fact!!
but if he is ruuning a basic street car ss springs will be
all he needs ,
ss spring will run in the 8 -9 sec zone without any hassel!!
i have run stock springs at 11,0 s
there is alot of stupid things i have done thru out the years
waste money is one of them
there is alot to be said about the front end of the car
and making the car leave than tons of money spent on the rear
for no good reason
