C6 GS Drag Radial Wheel/Tire Combo
It seems that "conventional wisdom" (Forum style ) says you can't get a C6 GS into the 9's on NT05R 345/30/19 Drag Radials mounted on GS OEM 19" X 12" rims. Is this possible on a consistent basis?
If not, what is the "preferred" wheel and tire combo that will simply bolt on the GS without spacers, hammering the brake calipers, etc. and hook consistently at HP levels required to run in the 9's? I have seen a number of combos that appear to need "massaging" to rear components...I want to keep the hammer in the toolbox.
Thanks in advance.

Probably the most used combos are Hoosier 275 on C5Z06 fronts and Hoosier 315 on either the former or C4ZR-1 rears.
As always, the best choice is the narrowest tire at the highest pressure that will still hook up.
If you haven't run 10's yet with your current tires, then the 275's would be the most prudent starting point.

I love my 345 NT05Rs... Prolly not the best tire to try and go 9s with tho, awesome all around street tire tho! Hook from any roll speed... But from a dig they def are tricky to launch and need some heat ran thru them and launched perfect to get a good hole shot... If you wanna get things simple like started above just get c5z06 front wheels and get a sticky tire... If you wanna spend some $ get a drag weld setup with some good drag radials man

I've contemplated buying another set of the front OEM 18x9.5's and having them sent to Weldcraft for expansion to accommodate better DR's. I'm already having issues on the street w/ 19x345 NT05R's, and I have more mods planned. Obviously, YMMV on the strip with burnouts.

The NT05R's held pretty good at 595, but once I added meth, the whole powerband was tuned much more aggressively throughout the band, not just max HP. Very noticable difference that goes beyond a ~11% gain at max HP.
I'm going to need to do something tire-wise when I drop a pulley and add a cam and E85.And I'd submit that the margin of error between different dynos is easily 5% at this level.

I can't hold on WOT in first and second is pretty squirrely. ~6K miles on them, but plenty of tread since I haven't stripped them. Third fwy pulls are fun.

I think those tires only good for about 3K miles. Mine hold pretty darn good.

True, I do run at 30PSI, as I actually drive on freeways and the banking interchanges between them.
Even at 30 PSI I find the extra sidewall much more wobbly than a regular tire. Everything is a tradeoff. I find that the NTO5R's mate better with NT05's up front than the stock Goodyears, which shouldn't be shocking to anyone.

Anyone running these on their GS? Anyone know how they compare to the Nittos?

You really want some side wall. Get some 17" welds and run a 335 hoosier if you want the best without breaking the bank. If you really want consistent 9s with good tire choices I would just pony up and do the 15" conversion and run one of the many 15s available. 275 pro, 325 et street, 26x12x15 ET drag, etc.

Another vote for C5 Z06 17" front wheels with Hoosier275/40-17 drag radials. We have several cars running great times with this setup and it clears your brakes. You can also run Mickey Thompson drag radials, but they are heavier than the Hoosier.
Remember, a drag tire squats during launch lowering gear ratio and grows on top end increasing gear ratio. To do this, you need as much sidewall aspossible. 18 and 19" wheel/tire combinations are not optimum.
