Help with Drags
So with covid going on its a little tough to find a pair of rear drags with MT ET Rs financed most shops dont have any. So what i did is i purchased a set of c5z wheels 17x9.5 called it a a day. I need a little help my current set up is FBO Huge Cam and E85 weight reduction also im about 490ish 500ish or so. What tires can i mount on these 17x9.5? Can i still get MT ET Rs 305/45/17? Or? Any help is appreciated. TIA.

I use the ET Street S/S drag radials in 305/45 -17 mounted on 17x11 rear wheels on my 2011 GS
You could do it, but a 9.5" wheel is really a little too narrow for this tire.
I would opt for using a 275/40 -17 drag radial with your 9.5" wide wheel.

At 500 or less RWHP, a 275/40 -17 drag radial will be more than enough tire for good 60' times.
You don't really need a 305/45 -17 at that power level.

Edit ... In fact, the larger diameter 305/45 -17 tire may actually slow your 1/8 and 1/4 mile trap speed down vs using the 275/40 -17

Still, for 'roll racing', get a set of the smaller diameter 275/40 -17 drag radials.
BTW .... If you ever plan on driving the car on wet streets in the rain, do yourself a favor and get the ET Street S/S drag radials instead of the ET Street R drag radials. The ET Street R tires are dangerous on wet roads.

Since your thread was titled "Help with Drags" ... I got the impression you were concerned about launching the car from a dead stop.
