will 26x11.5 et street fit?

[sn95gt19]

i am probably going to run prostars 15x8 w/ 5.5 backspacing. the actual width of a 26x11.5 et street is 12" (im pretty sure, correct me if im wrong) im going to stay with the 26" tire though, i only have a 3.73 gear, so the 28 probably wouldnt work to well till i get a taller gear. im kinda torn between the simplicity of a blower and the power of a turbo(and lack of abuse on the crank) so if i do go the turbo route i want to keep the 3.73 and just run a 28" tire to tone the gear down, but if i go blower im definitely going to put at least a 4.10 or 4.30.

i dont have an anti roll bar as of yet.........im thinking about getting one but i dont know if its really going to help all that much, plus it will be driven to the local street racing spots. and i have heard that it doesnt fare to well on the street.
did yours help a lot???

thanks
