Oooo sorry didn't catch that! So anyone know what would be some really good suspension mods to help stop the spinning?

INCREASED ACCELERATION
CAMARO 1LE 3.91 GEAR KIT
P/N 22756880 / On-Sale Date: Late Q3 2013/Early Q4 2014


If you want the ultimate acceleration off the line, look no further than this shorter gear ratio. This ring and pinion comes out of the 1LE, and the higher numeric ratio gives your fifth-gen Camaro a dramatic increase in acceleration. The drive gear increases effective rear-wheel torque multiplication by 13 percent in a manual-transmission Camaro SS, and a whopping 20 percent in automatic cars.
The complete 3.91 Performance Gear Kit (P/N 19301504) includes the ring and pinion, all hardware, shims, gaskets, oil additive, and instructions (included, not shown). The 3.91 gear installation requires recalibration, which is installed by a GM dealer. Application for a CARB E.O. has been made at the time of this writing.

Sure they have 3.73 gears - ya' just gotta pony up the cash for a ZL1 diff, axles, driveshaft, etc. package available from GM performance.

A quick mental calculation has me thinking a 1.5" or so taller tire would put your final drive ratio closer to 3.73. Dunno if you have the room 'cause I dunno what height tire you're running now.

In the old days, we would run 10x27 tires at the 1/8 mile tracks and 10x30 tires at the 1/4 mile tracks. It proved a great combination for a mild big block with 4.88 gears behind a turbo 400.

I read for days in attempt to find someone that had real world experiences in 3.91's in an a6 l99 car.. most recommended against it with no further information to back it up.
I run my car 1/4 mile at street legal open track days.
Bone stock I was averaging 13.8's at 100-101mph with stock 3.27 gears
I decided to install the gm 3.91 kit against everyones advise. most told me it wouldnt hook and would loose top speed in the quarter mile.
After the install. The GM dealer even reprograms your speedo free of charge!
I brought the car to the track with my new 3.91 gear set installed. Everything is was stock
First Pass was a 13.28 @ 105.9 on a 90* humid day.
Car was a half second quicker with an increased trap speed of almost 5mph.
Hands down the best bang for your buck mod.
