I was wondering what needs done to a stock 2SS to add the 1LE package?
!. suspension upgrade.
2. Wheels.
3. 6-piston Brembos
Anything else? Starting with a 2017 2SS with Mag shocks, NPP exhaust and A8.



I don't care about cosmetics i.e. seats, hood, mirrors or spoiler satin paint just the performance mods.

I'd say wheels and 6-piston brembos are cosmetic anyway as well.

In anycase, from the sticky:

Camaro SS 1LE
The 2017 Camaro SS 1LE introduces the new FE4 suspension to the Gen Six Camaro – a performance-oriented chassis system with specific tuning for the Magnetic Ride dampers, springs and stabilizer bars. Additional highlights include:
• 6.2L LT1 V-8 rated at 455 horsepower, and six-speed manual transmission (automatic transmission not available)
• Magnetic Ride Control
• Segment-exclusive electronic limited-slip differential with 3.73 ratio
• Unique forged aluminum wheels with 285/30ZR20 front tires and 305/30ZR20 rear tires
• Goodyear Eagle F1 Supercar tires with a compound and construction developed exclusively for the Camaro – offering exceptional grip on the track
• Brembo brakes with new six-piston monobloc front red calipers – featuring the 1LE logo – and two-piece rotors. Measuring 14.6 inches (370mm) in diameter, the front rotors are 7 percent larger than Camaro SS
• Track-cooling package, with engine oil, differential and transmission coolers
• Suede steering wheel with shorter-throw shifter
• Dual mode exhaust system
• Recaro front seats with aggressive bolsters optimized for shifting and steering comfort
• Satin black hood, front mirrors and unique three-piece rear spoiler
• Satin Graphite front splitter and rear diffuser
• Available PDR video/data recording system.

Since the 2SS in question has MRC and NPP (dual mode exhaust) from the factory, many of the missing 1LE features can be added, but there still are two things that cannot be retrofitted with any reasonable effort, so a 100% upgrade is not realistic:

• Segment-exclusive electronic limited-slip differential with 3.73 ratio
• Available PDR video/data recording system.

The PDR has third party alternatives, but the e-diff cannot be swapped in. (Coolers are the same as on the standard SS.) The spoiler and especially the splitter are also performance mods.

Now as to how much these contribute to a car's "1LE-ness", the jury is still out. Obviously, 1LE owners will say the e-diff and its associated PTM driving modes make all the difference in the world, but my car has a lot of the 1LE goodies—and if I'm brutally honest, my driving skills are not at the point where I would seriously be hampered by the lack of these two above, so for someone with little track experience the e-diff may not matter that much. My car is already tangibly superior to a standard 2SS due to the upgrades applied.

OK This is how you do it:
Suspension Kit Part Number 84203549 (shocks, springs, etc.) and the SWAY bar kit part number 84401188. This is more commonly referred to as the SG3 suspension. Note: My SS DID NOT have MAGRIDE so the part number for the spring upgrade MAY be different.

MY own car is a BLACKED out 2019 Camaro SS2 with A10. AMP installed an upgraded wheel and tire package that included APEX SM-10 19 x 10.5 wheels wrapped in Michelin Sport 4S 305 30 19 tires. This combo is ROTATABLE and with currently has 9K miles on them , the tires show only about 30% wear so far with about 20 20 minute track sessions.

VORSHLAG camber plates were installed which allow be to go from my STREET alignment FRONT wheel settings of -2.2 degrees negative camber to 3.6 degrees negative camber in a matter of about 10 minutes at the track. I run also -2.2 degrees negative camber on the REAR for both street and track use. I ROTATE the tires and wheels every 2500 miles or so.

AMP installed ZL1 brakes (15.3 inch front rotors) on the front and the rear of the car (special note: The SS brake package is the SAME as the ZL1 brake package on the REAR of the car so the improvement in braking is due to the front brakes ONLY. I have NEVER noticed any amount of brake fad at the track even when braking VERY hard.

POWER improvements by AMP push the power to the 500HP range but additional upgrades should make this around the 580HP level NA with NO associated issues with supercharger heat soak issues. The car is ABOUT 250 pounds LIGHTER than a ZL1 so even using the dual purpose MS 4S 300 treadwear tires, the car handles EXTREMELY well and is absolutely NEUTRAL in its handling characteristics.

Car is used as daily driver and is considerably more fun to drive as a dual purpose car than the ZL1 1LE that I had for a short period of time. PLUS the car doesnt ride like a dump truck when used as a daily driver on city streets.

Okay guys I have a question. I have a 2SS it has the 1LE track package no the 1LE. It's a M6, has NPP, Mag ride and Recaro racing seats my question is do I have the ELSD or the 3.73 gear ratio.

If it is not a Factory 1LE you do not have the eLSD.

shoe, I know you don’t really want to hear this but if I was wanting to mod my 2SS with 1LE parts, I would look for a used 1LE optioned SS to replace my 2SS with. Sure you can add most of all the parts but it won’t be cost effective and you still won’t have after you’re done a true SS 1LE Track Camaro. Those Recaro seats are nice in the 1LE and of course the eLSD is good too. I do understand what you are wanting to do and as mentioned you could buy the Chevy Performance parts 1LE Track Pack kit for your SS and get a nice set of aftermarket wheels/tires and that would make a difference in the suspension of your SS. I think Chevy even offers with that suspension kit a reprogram for the 2017 and 2018 SS suspension once it’s installed in your car. As others have replied there are ways to get to your goal of a better handling 2SS and just search around on the internet to get ideas. Good luck with your project!

No you do not have the Elsd and 3.73 gears and I am not sure if anyone has successfully added those a non 1LE car.

I have a 50th edition and don't want to part with it. I like the idea of a 2SS 1LE Auto.

You definitely have a very special car. Doing what I did, inching the car towards a 1LE, you'll definitely have paid more in the end than if you'd ordered a 1LE, but you can pick and choose which parts you want. True, the result will never be a true 1LE, but you still can get pretty close.

A couple of points/thoughts:

• 6 piston brakes are absolutely not cosmetic only. They are better than the 4-piston SS brakes at handling energy/heat dissipation, which is especially important on track. ZL1 brakes are slightly better yet, but not necessary unless you're adding more power than stock and are able to push the car to the limit on the track.
• You've got most of the changes aside from the eLSD as others have pointed out. Unfortunately, there's no way to integrate it after the fact without buying a car with it from the factory. Integrating it would cost way more than just trading up since it's a new rear end, new ECU to control it, new wiring harness, and flashing a bunch of modules to work with it. You're also going to be missing PTM but also can't be integrated without the eLSD.
• Suspension upgrades are anti-roll bars, some links and knuckles (for bushings), and springs. Spring may or may not come with a new MR cal to accomodate. I know they were supposed have that available but I also remember hearing there were issues where dealers couldn't flash the cal. Not sure what happened with future model years, but either way make sure you confirm part numbers and fitment before buying stuff.
• For wheels/tires I'd suggest sticking with staggered sizes like the 1LE's (20mm wider in the rear and 30 aspect ratio for each) for easiest setup. Going to a square setup will make the car prone to oversteer without additional setup changes being made. If seriously tracking the car regularly and only using one set of wheels, I'd suggest the Goodyear SC3 for tires. They're great on track and will be fine for pretty much any street driving condition.
• If going piece by piece, I'd start with brakes first. After that, wheels and tires will give the biggest performance increase. From there I'd guess springs, then roll bars, then links. Not 100% sure on the order of the last ones without data, though.

Also, side note, the option to have auto 1LE's is also coming from GM if you haven't seen it yet. It obviously won't have the 50th specific cosmetic details, but seems like it gets all the performance things you want integrated out of the box.

You can add some of the goodies to a regular SS, but you cannot make it into a 1LE. Cannot add the eLSD afterward and the car will not have the PTM. Also as noted it will not have PDR either.

As far as what you're missing by not having the eLSD and PTM, Chevy did a test where they modded a regular SS with their 'lowering kit' consisting of springs and shocks, added the 1LE handling kit (sway bars and links), plus added the 1LE tires/wheels. Was not mentioned whether the SS had the base 4-piston or optional 6-piston front brakes. The modified SS, while noticeably improved over stock, was still 2 seconds a lap slower around their track than the actual SS/1LE was.

Here is the thread with the details: https://www.camaro5.com/forums/showthread.php?t=542333. Basically, the stock SS went 2:08:50, the modified SS did 2:02, and the 1LE went 2:00.

With my driving skills, I'd personally take the 6+ second improvement over stock instead of trying to trade or sell/buy.

Majority of owners don't track their 1LEs, let alone Camaros. OP never mentioned anything of the sort. On the street in a Camaro cruise you'll never notice a difference and it's a huge waste of money. I'd still start with a stock 1LE and go from there instead of turning a regular SS into one. Probably easier to throw an auto in a 1LE.

I almost guarantee the OP won't go that route once he sees the costs of sourcing parts and labour to install all the components. He will have a "unique" auto 2SS 1LE that will be worthless on the used market, people want unmodified stock cars. Good luck though.
