That's the only place to jack up my Z because it's too low. But it is safe as long as you put jack stands. That's one thing that my dad has taught me, no matter how much you jack up a car put jack stands underneath it.
Dang I wish you were still here because I'm putting a 1jz in my 280 and probably could use your help.What did you do for mount??? Do you have a build thread???
