Caltracs question

Hey all:

Started running at the track and want to make it a competitive bracket car. Been making some good data runs at T&T. Best ET is 12.59 w/ 1.770 60' thru full exhaust

360/380 magnum crate motor, automatic and footbraking. M/T street radials and stock replacement shocks all around.

I am using super stock springs and am wondering if it would be worth my investment in Caltracs or not? Is there a rule of thumb where if you are running a certain ET that it's worth investing in their setup?

Car has been consistantly hooking up until now but we had some problems hooking recently as we've been steadily lowering our ET to mid 12's. Car kind of sits a bit high w/ the SS springs and I'm wondering if I went w/ lowered split monoleafs and caltracs if it would give me better weight xfer?

Any help would be appreciated.
