My plan is to go with 275/30/19 on 19x10 C6 rims. However, I originally planned to go with 18x8.5 with 255/35/18 on the front, and then the 19x10's w/275/30/19 on back, but I have since decided I don't like the staggered sizes on F-Bodies and I'm now looking for another set of 19x10's.
I'm going to post pics of the 18x8.5's in hopes of either selling them, or buying another set of C6 rims and keeping 4 19x10's and then sell a set of 4 18x8.5's. For right now, this page is dedicated to making that happen. Once that happens, then I'll convert this page into info on what it takes to make 19x10 C6 rims to fit all the way around.
Front 18x8.5 C6 Rims are SOLD along with the 255/35/18 Tires.
I now have all 4 19x10 C6 rims, an Eibach Pro Kit, BMR LCA Relocation Brackets, Pair of 275/30/19 Michelin Pilot Sport A/S Tires, and 2 1.25" adapters/spacers.
All I need are 2 more tires, another pair of adapters/spacers and I can get this project completed.
I just had all 4 275/30/19 Michelin Pilot Sport A/S tires mounted and balanced on 19x10 C6 Rims. I have an Edlebrock Adj. Pahhard Bar I need to install to re-center the rear-end before I can install the C6 rims. I also still need to purchase another pair of spacers for the front. The Eibach Pro-Kit and BMR LCA's along with new shocks are now installed as well.
FINALLY! I went out this morning and installed the rims!
