You can lower you ZZ. I lowered my PT but it does scrub sometimes. But it looks sweet!
My intention was to get my dremel out and place a slot above the already stock one, but I was lazy and did it with an Xacto insted. I broke through into the stock one and now the hole is bigger than I wanted it but it lowered the car pretty good.
Either I'l leave it just to show or I'll sand, putty fix and repaint. It has a wing on the top back too. Like a ricer car. And BLING BLING! Gold spoke rims
