ET Street SS or ET Street R.
Make my 18x11 rims work, or sell them.
Buy a set of 17x9.5 or 17x11.
Keep as close to 27.6 as I can for minor tune adjustments, or drop to a 26" and pull fuses and fuss with my shift points/tune.

First, I would definitely NOT recommend pulling the ABS fuses. I tried it on a few passes to get rid of the 4000 RPM idle limit and remove the bog and it did not behave as I expected. Very unstable, too unpredictable and dangerous! See this thread for my trial and error: ABS Fuse Pull on 6th Gen ZL1

I was leaning toward the 26"x12" Hoosiers for the leverage and traction I needed. They're like 12 lbs lighter than my MTs too. Now I'm worried whether stabilitrak will pull timing even with the "nannies off", as wnta1ss described in your thread "Tire size question: Stock fronts with 26" rear. [Post #2]". I always race with the nannies off. I really don't want to cripple myself out of the gate like that. I need to confirm this with other ZL1 owners.

Can any ZL1 owners confirm this problem with tire-size mismatch pulling timing? At what point does it become a problem? 1/2" - 1" - 2" shorter?

I like how you've laid out your choices in a spreadsheet. With all your power mods you want to get meat to make use of all that muscle. You've probably already tuned out the torque management bog so your problem is a bit different than mine. You want to dead hook at the tree and keep it planted through like 6 gears?

HaHa! What fun would that be, though? Who ever got any great degree of satisfaction from doing something easy?!

My brother has a set of 28x10R17s on his 2018 A10 mustang, they're a bit tall and made his 2k launch a bit sluggish, but he hooks, so now I've Got to find a tire that will Hold all the LT1 torque and Not hurt my overall gear ratio so I can get out the hole Better than him.

Good luck! I'll be interested to see what you go with...
