Seems pretty low of tire pressure for IRS, does it get a little squirrely at the end of the 1320???

And by preload do you mean you slip the clutch a bit before getting the green with the handbrake fully on?

Well the tires are designed to be run that low, but my HKS Drag IRS suspension is working quite well, I did run higher pressures but that didnt really work out.
Since fitting the front Skinnies as supplied by turboR1 its very stable at the top end of the strip. When I had normal Radial tires up front yes it did get very squirrely after the 8th.

Preload question..Well I get the handbrake fully on at the line and bring the clutch to just about the biting point without slipping to much then dump the hand brake and clutch at the same time at green, I do it so quickly I couldnt tell you how long im on the biting point when I stage up.

Good to know! Real nice launch and numbers, especially on IRS and stock trans, props to you.

Just out of curiosity, I know the HKS rears are 3 kg/mm (~170 lb/in) which is quite a bit lighter then the usual street/race coilovers, but what else makes them better for drag?

There valved for it..

Road race shocks are not designed for drag.

In drag racing you want the car to squat and stay squanted.. Not bounce back up and unload the tires..

yeah, I've ran as low as 7-8psi in my old ET Streets......to compensate for the blown shocks and f'd up 4 link. Didn't really help but made for some butt puckering runs..

I meant on independent rear suspension, I thought they get pretty squirrely below 14 psi. I'll shut up and go back to my igloo.
