Get my car to launch better...

I just thought I'd update this - I put longer shocks in, and clamped the front section of the rear springs. The wheel hop is completely gone, but I'm still spinning off the line. Everything worked better when I lowered tire pressure to 16psi. I was at a track at higher density altitude (3000'), so my total ET was higher - 13.426, but my 60' times dropped from a previous best of 2.16 to 2.02. I tried doing burnouts in second, but when I try to hit the brakes to hold position my rpm slows, the tires grip and I almost stall the car. I'm planning on putting battery in trunk and installing a line lock to compensate for my lack of athleticism doing the burnout. My plan is to put the line lock right after the front output on the master cylinder before it hits the proportioning valve. Anybody see any problems with that plumbing plan?
