17X11's ??? are they out there??
 

my car want hook ups at all after shifting into 2nd @10psi. The car kicks side ways(there know counter steering) I want to know if there is a 17X11 or 10. Also is there a drag radial that will fit that rim? I have 18 inch enkie's with kummo esta supra tires. Do the kummo tires suck at hooking up or what???

max on a stock FD rear would be 10in wide wheel and you can go up to a 285 tire. I have 17x10s out back with 275s and they fit perfectly.

any wider would require bodywork or flares. 17x12s will allow 335s out back. You will have to get custom wheels like fikse, kineses, ccw. Same can be done with 18s.

You can go up to 10.5 x 18 with 285/30-18 in back...

The problem is those shitty Kumho Ecsta's you're using....put some decent tires on and see if you get an improvement. BTW, what kind of power are you putting to the wheels?
