Best DR for 18x10.5" wheel ZL1

Hey guys, I posted this in the dragstrip section but since I have a ZL1 I will try here also...

I tried my C6Z drag setup 18x10.5 c5z rear wheel with MT ET II 315/30/18. Every check engine light there is went off even abs, emergency brake and power steering EVERY ONE OF THEM... I think that my Z06 setup was WAAAY too short for the ZL1 (25.5" tall vs 28.4" stock). What would be the best size for gearing and traction while fitting my c5z rims. Without setting off the computer's sensors???

The next tallest MT is the 305/35/18 at 26.4" . Also a NT05r 285/40/18 at 27.09" tall...

I know that both MT and Nitto have options on a 18" wheel @28.5-28.9" tire but that would not help by actually adding gear...compared to stock...

Any opinions and advice is welcome. I didn't feel comfortable going through the traps with no power steering and the rear brakes not working right...

most people use the 305/45-18 which is 28.8 inches tall which is close to stock height. I have been using 305/35/18 which are about two inches shorter and I have not had a warning light so far. My car has been tuned, however, and the tranny calibration has been changed.

I'm running an 18x9.5 40mm offset with a 305/45/18 Nitto NT05R DR and have no issues at all. I definitely think it is due to your tire height. The 305/45/18 is almost identical in size (about 1.4% difference IIRC) as the stock tire. There is a website 1010tires.com this has a great tire size calculator that I would recommend to help you figure it out. You can plug in several tire size next to your stock size and the will tell you the differences.

Thanks for the responses! I was thinking that a shorter tire would be better for ET's and getting out of the gates (pending NOT setting off the CEL's and CPU sensors)...but it looks like most of you are going with a stock-size DR or even a bit taller...confuses me, but yall have the experience with the ZL1 that I don't...
