Need Help With Tire Size for 1/4 Mile Run

I had 195/60R15's
Then I moved up 10 215/50R17's
Now I want to change to 215/35R17's. My thinking is that I will be lowering the gear ratio for a faster 1/4 mile time with a lower trap speed. I'm aware that this is alot under the stock diameter, and the 50 series tire on the 17 inch rim is oversized. Just trying to get into the 14 sec zone in the quarter mile. Right now with the 215/50R17's im running about 92mph@15.2 secs. Any thoughs or experience with this?
No, i'm interested in slicks and what not. Just the tire size question. thaniks in advance.
