Light Wheels & Sticky Tires For Launch...?

I'm trying to arrive at an ideal combination of tires and rims for launching my `11 RCSB 2WD Hemi ST. Curiously, the factory 17 X 7 steel rim weight seems very elusive--I've read numbers from 23 to 33 pounds each. Does anyone know with certainty?

To the point, I have a K&N CAI and 14" straight-through muffler. I plan on 4.10 factory LSD gears, Y-pipe, removal of trailer hitch/spare tire/tailgate plus an Edge 2800 stall TC (it is also my daily driver). My truck is lowered 2" in the rear. I would like to use M&H 275/50R17 drag radials that are 28" tall (stock height is 31.6"). M&H specifies a 9" rim for that tire. I have found several 17 X 9 Ultra wheels that weigh between 24 and 25 pounds that are "supposed" to fit. I am thinking about using General Grabber UHP 275/55R17 up front (and on the rear for the street).

Since a tuner is not yet available (and might never be), I intend to have some 1/4-mile fun with the stock engine but...the truck must hook. I want 60' times under 1.8 seconds. Otherwise, there is scant motivation for me to proceed. I haven't spent much money on these plans...yet. So I have to ask you experienced guys, will these mods achieve my goals? Your input will be greatly appreciated before I make an expensive mistake! :Hey:

Thanks!

I have to spray to get 1.7 60's, I need a tq verter to get 1.8's (and I'm modded heavily)... i think your first goal is to get sub 2.0 60's , dr's, tq verter definitely helps but since you don't have a tuner it will be difficult altho the 4th gens are pretty quick...

Ha...it's interesting that you mentioned battery relocation. I am in the process of doing exactly that with a generic Summit kit. I figured that the weight loss from the rear would complicate launch traction and decided to redistribute a few pounds from the front to the rear. I just bolted the new plastic battery box to the passenger side behind the wheel well. I haven't run the cables yet but the kit came with 20' of 2 gauge cable. I've done this before and it definitely helps.

By the way, you have an awesome truck. :smileup:
do you have the part number on summit..I think I'm gonna go that route to although does anyone know about the nhra rules about battery location? or is that just battery shutoff switch..
