Getting ready to order the rear and want to make sure I order the right gear. Car is an M6, 3900# with me in it, 430 rwhp 410 rwtq, 6600 rev limiter. Looking to probably run the 26 in et drag stiff sidewall. Don't want to modify the wheelwells. Car runs 12.20s at 116 now on 275/40/17 dr with only a 2.0 60ft, 10 bolt with 373s. Looking to go mid 11's after rear and tires, all suspension is done already, also have a drag bar waiting for the new rear. Thanks

I would go to a taller tire and run 4.56's for optimum performance, but if your set on using a 26 you probably need 4.10.
There is a gear and tire calculator in the rear end section, and judging by your mph you can nail down the perfect combo so your crossing the traps near your redline...

depends on the tire, either look it up or call the manufacturer, typically a bias ply will grow close to 1in but that just a rule of thumb. A radial will hardly grow..
The taller the tire the easier it is to hook, that is most 6-speed guys move to a 28 and 4.30-4.56's... it eliminates the bog and allows you too hook easier..

Looks kinda like the et drag is 26.5 in the stiff version which would max me out at 121 mph at 6600 with a 4.30 gear. That is not factoring in any growth for the tire, so I think that should be good. I cant see my car picking up that much mph unless i lighten it up. Do you think a 26 in et drag will hook with 4.30 gears and 430 rwhp?

First,if you want to hook get off the m/t tire bandwagon. They do not seem to work well on my cars and i had no luck with them. Try the M&H Racemaster. I run the 26x11.5x15 and cut 1.42 to 1.44 60 foots in a m6 car with 4.11 gears. I dump at 6,500rpm's and it's a dead hook. you do not need a 28'' tire and 4.56 gears to make the cars go. And if you want to street drive,the 4.56 will rev higher on the highway. I now run 10.6 ant 130mph on a 26'' tire and hope to go faster after this winters mods. Good luck to ya. www.intercotire.com By the way,my boy thought his 60's were good on his m/t tires. I got him to try m&h and thats all he uses now.

I'm definitely open to other brand tires. Are the M&H's slicks or dot tires? Only reason I was looking at the et drags is because they make a 26 in version with the stiff sidewall. 4.10 gears maybe where I end up, but the 4.30's would definitely help get my heavy *** car moving. On the street with street tires might be another story. How many passes are you getting out of the M&H's vs the et drags?

There is also nothing wrong with M/T tires.. ET Drags are a proven tire on combination after combination, maybe you need to stop being a bandwagon tire person and be open to something other than M&H.
I bet 4.56's and a 28in ET drag would improve your 60' especially if your dead hooking at the moment

Can you make a 26 and 4.11's work.. YES, is it A LOT more difficult.. YES

I'm not exactly sure why every one seems to be afraid to gear their car up with an m6? What you want is a first gear final ratio of around 13.1. You can find this out by multiplying your first gear ratio by your ring and pinion ratio, for example 2.66 (1st gear) x 4.86'( rear gear) = 12.92 first gear final ratio. This is what some old time who used to run stock eliminator in NHRA in the 60s told me and it has worked for me. I do run a 28 inch slick and turn 6800' rpm though.

In addition to what has been said. depends on the car 26 to 28" Bias Ply, and gearing to match N/A = 4.56 or Nitrous= 4.10/4,30 and a good clutch. I will also mention parts like Drag Sway bar for the rear, adj shocks, and M6 TQ Arm relocation kit.
All these things will help when you let it fly @ 5k.
