what can be done to lower 60ft time?

Thanks for the replies guys.
MT's would be fantastic, but they're a luxury I can ill afford. (you can probably tell by my modest ET and trap speed it's a low buck set up) I do have a roll bar which will pass tech, that'll enable me to use some cheaper non DOT slicks, But the back seat is too handy to lose the use of.
The car is about 50/50 street and strip. (ie, I barely drive it) So I don't want to do anything to do too many mods that I can't undo for street use.
I shouldn't have too much trouble running out of revs. ATM I'm hooking forth gear around 40-50 metres before the finish line.
