Here’s my personal notes on what’s a 1LE that I created back in 2012. You may need to refresh this for your 2015.
SS 1LE Performance Package
This SS 1LE Performance Package bears the iconic 1LE option code that is a Camaro[emoji768] legend. This competition-ready package has been coveted by both Camaro owners and track enthusiasts. This SS 1LE Performance Package includes:
* 20" x 10" front and 20" x 11" rear aluminum wheels with a 10-spoke design from the ZL1[emoji769] and a low-gloss Black finish
* 285/35ZR20 Goodyear[emoji768] Eagle[emoji768] Supercar[emoji768] Generation 2 performance summer tires1, front and rear
* Performance Ride and Handling suspension with front and rear stabilizer bars for excellent body control and vehicle responsiveness
* TREMEC[emoji768] 6-speed manual transmission with a 3.91 final-drive axle ratio
On 1SS models, this package requires Black Sport Cloth interior. On 2SS models, this package requires Black front leather seating surfaces interior. This package is not available with 6-speed automatic transmission, any stripe package or any dealer-installed wheels.
1 Summer-only tires tend to wear faster and are more susceptible to damage from road hazards or curb impact than standard profile tires. This type of damage is not covered by the GM New Vehicle Limited Warranty. You may want to get different tires if you expect to drive in winter conditions. See your dealer for proper tire selection.

Here are list of 1LE features:
* close-ratio TR6060-MM6 six-speed stick
* final-drive ratio of 3.91:1.
* The transmission also gets a cooling system, like on the ZL1.
* The V-8's output is unchanged from that of manual SS models, at 426 hp and 420 lb-ft of torque.
* Suspension modifications include
* a larger, 27-mm front anti-roll bar,
* a 28-mm rear anti-roll bar,
* ZL1 toe links,
* ZL1 rear shock mounts,
* a strut-tower brace.
* Beefier half-shafts are supposed to help cope with the improved traction
* wheel bearings come from the ZL1
* the fuel system has been upgraded with the ZL1’s high-capacity fuel pump and additional fuel pickups to avoid high-g fuel starvation.
* 20x10 front and 20x11 rear wheels are inspired by the ZL1’s rims
* 285/35ZR20 Goodyear Eagle F1 SuperCar G: 2 tires at all four corner
* specifically tuned monotube dampers in place of the Camaro SS’s standard twin-tube unit
