Clat trac vs. SS springs vs 4 link

hi, the caltrac system is the best way to go.it's simple, and it flat works!
as for how fast? the A/SA record in NHRA is 9.98 on a 9"x30 " tire and caltrac system. the caltrac will produce faster 60' times and be very consistent. calvert sells a complete system, bars, rancho 9 way shocks, springs. the ladder bar and four link require chassis rework and expense.
the calvert system bolts on. look on calverts web site, his SS/G mustang will stand car on it's back bumper, with 9'x 30' tires. you can call them, they are very helpful.
