Yep just test fit my weld rts 17x10 today. Good fitment with good clearance for a 17.

What RPM are you crossing the line at? I'm in a similar situation and trying to figure out how tall of a tire to purchase. I've not been able to get a clean pass on my sh!tty NT555 G2s to accurately calculate my finish line RPM.

-Thanks

I don't know I was so estatic that I ran back to back 10 sec passes. I called beef cake and two other vendors and the recommended 305/45/17 ET street r

Yes, but not for long converting to e85 this weekend. Hoping for bottom 10s at 136 mph on a Da of 380. That was the DA of the 10.88 run.
