try launching at around 4000 - 4500 rpm (without spinning the tires) holding off the clutch a little and floor the gas pedal. shift to 2nd gear around 6000-6500rpm then to 3rd gear. i have a '90 n/a 5spd (stage v) with semi-ceramic clutch and have problem launching the car too. i've tried launching at a lower rpm's but the times are not so great. also let some air out of your rear tires about 20psi. good luck. i'll be racing this friday too.
