I'm not sure if I should get the 26 or 28 (by 10.5) tall M/ts slicks
Im gonna be spraying 125 or maybe a 150 shot out of the hole (mods in sig.)
I will think that the 28 would perform better since I plan in sparying out of the hole with an M6.
But what do you guys think?

I think that you will blow up the 10 bolt launching on slicks and nitrous out of the hole. I believe the a 10.5 wide 28 inch tire will not fit without significant modification to the rear fenderwells, but the 26x10.5 will fit pretty well. Also, the 26" tire would give you a better gearing advantage as you will not max out 4th gear with your combo. 5700rpm in 4th gear with a 26" tire is ~129mph, and ~139mph with a 28" tire. 3rd gear is 99mph and 107mph respectively.

I ran a 28x11.5-15 (28.0" OD) Hoosier QTP in the stock wheel wells. The axle assembly had to be move back about 1/4" to avoid hitting the front sheetmetal edge of the 1/4-panel, when the tires grew at trap speeds over 125MPH. When I switched to a 28x10.5-15W ET Drag, it required considerable cutting away (1.5") of the rear bumper cover, even though the ET Drags are only quoted at 28.1" OD.

For a 125-shot out of the hole, a 26" or 27" tire should be adequate. Consider a 26x11.5, or a 27x10.5 ET Street. Remember to take into consideration your estimated trapp speed as noted in the post above, since going from a 26" tire to a 28" tire is like reducing you rear end ratio numerically by 7 to 8%.

If I were you I would do the 26x11.5. The 26in. tire will be better for your gearing and then 11.5 will offer just a little more traction than the 10.5.

I also forgot to mentioin that I will be getting a 12 bolt as well, with 4.10s
My purpose: Have full traction=zero spinning!!

You don't want "zero-spin"

You want about 180 degrees of rotation.

Explain please!

Motor boggs if you have no spin. That is what he is saying. There is a certian ideal spin to the tire. It allows for higher trap speeds and doesn't bogg the engine down......also no spin usually breaks things faster.

Thats one good thing about the wrinkle wall of most slicks, it gives you a start on that.
