tires depends on certain things. mostally type of tires and the track condition. i personally like dropping it down a bit. but you dont wanna get very exxcessive when dropping any tire preasure or raising it for the matter. try 1 psi at a time.

Better start shopping.

where is the best place to order one or have one built.

what is the typical cost?

This is my wife's DD so I'm not going ballz out on anything but would like stronger and maybe a little more responsive. I know when I first started on my Z the stall was one of the best mods I did. Again, remembering this is not going to be all out race car, what is a good stall speed you guys tend to use?

I would say start in drive and put it in tap shift after you hit second and ride it out.

first of all, nobody has broke their trans drag racing.
so stop worring about it. put on a cooler, install a shift kit and get it tuned. change the fluid and filter every 20k or so. if it blows; then bitch.
strong enough for typical diy bolt ons.
keep an eye on trans temps and dont let the fluid get above 215*

these suggestions will not a fix trans that is already been over heated or on its way out.
