[Destroyer_1LE]

I wanted to start this thread for all the people that are getting a 1LE!!!!

I want to get everyone thats getting a 1LE onto one thread sharing there modifications they plan to do to there 1LE.
(This thread should only consists of performances modifications, NO EXTERIOR MODIFICATIONS THAT DOESN'T HELP WITH PERFORMANCES)

Here's my list:

Engine:
Cold Air Inductions - intake system (or possibly a K&N once it hits the market)
VMAX - CNC Ported Throttle Body
Catch can
Custom tune

Exhaust:
Stainless Works - 2" x 3" Long Tube Headers w/out Cats No Valves
Stainless Works - 3" Axle-Back w/Vavled Quad Tips for SW Headers

Suspension:
Lowering springs for better handling
(Subject to change)

Chassis:
solid bushings

Brakes:
Factory Brake ducts

Wheels/ Tires:
Mainly daily driving set up with factory 1LE wheels
Toyo R888
front: 285/ 35ZR 20
rear: 305/ 30ZR 20

Track setup and canyons runs:
another set of factory 1LE wheels 20's or possibly 19's
Pirelli P Zero Trofeo R
305 all the way around for 20's
305 front and 325 rear for 19's

Aero:
Wickerbill
Chassis Mounted front splitter

data logging equipment:
AiM SmartyCam GP HD 2.1

[slick3]

Assuming they get the 17 tuning figured out by then.....

Engine:
-RotoFab Intake
-Vmax throttle body
-MSD manifold
-Catch can
-91 Tune / E85 tune for track

Exhaust:
-Kooks / Afe / ARH headers and mid pipe (undecided)

Brakes:
-Fluid swap with Motol 600 and factory brake duct install
-Dedicated set of pads and possibly rotors. G-Loc's

Suspension:
-MRC springs
Not sure need to drive it first. Sounds like it's pretty compliant and well balanced. Maybe a bigger front or rear bar for adjustments if I autoX it. Might not (hopefully) need nothing!

Wheels: Second set of forged wheels with some Hoosier R7's, hopefully a squared setup.

Misc:
Really need a new helmet this year!
Some of those bad ass black GM tail lights

Are you planning on scca? Engine mods bump you up into a different class

Yeah I know.. I actually looked at NASA but in factory trim its already in TT2 and that gets into some real intense competition ($$$$)

I need to look up f stock rules, what's next step up? I just want to drive the shit out of this one on the track. I built my mustang up to track it and only went once. It never gave me confidence, hence I sold it while I could to get into a 1le. My buddies 5th gen in stock form felt better than my fully built mustang (2014)

Nothing. Drive it and track it as is (probably break pad upgrade for the track thats it). If I can drive it to it's limits some day and it's not enough buy a different car.

Same. Brake fluid and likely pad upgrade. Minor cosmetic touches like wrapped roof and removal of hood wrap. Probably 20X10 square setup with 285/30 continental dsw06's for all season daily driving. Keep the stock wheels and tires for track days or summer fun.

After that the projects

-remote controlled NPP "Fuse Pull" mod
-custom brake duct setup that can be blocked off for street use
-catch can
-e85 tune with ethanol sensor to revert to standard fuel tune automatically

I have discussed the 1LE with a few of my SCCA Autocross friends and assuming that the 1LE is faster than the GT350 (non R version) around the track we think it is unlikely that it will remain in the F-Street category. The GT350 is in A-Street and the GT350R is in Super Street so it would likely fall into the A-Street Category with the non R GT350. I believe that if the 1LE is allowed to remain in F-Street it will totally dominate the competition without needing a single modification.

For those of you considering SCCA Autocross and would like to get an idea of where your car would be classed with your planned modifications here is a quick reference list of all of the modifications allowed in each of the street classes from lowest to highest. (Street is the least modifications and Street Modified is the most modifications) Keep in mind any modifications allowed in a lower category are also allowed in the higher category, for example Street Modified can perform any modification allowed in Street, Street Touring, or Street Prepared. If the modification is not listed it is not allowed. In addition the Street Touring category has additional wheel and tire limitations with a maximum of 10" wide wheels and 285mm tires for STU where the Camaro would be placed, so the 1LE would need a tire swap to compete there. As you can see from the list a 1LE with a tune and its stock 20x11" rear wheels will instantly be moved to Street Prepared since the tune would bump it into Street Touring but the 11" wheels would be ineligible for STU and it would bump it further on to Street Prepared.

Classic American Muscle (CAM) is another option but is a completely separate class from the Street categories and is basically unlimited.

[BigEnos]

Alignment, 19" wheels, and 305 RE-71Rs.

[Iron Oak]

Other than upgraded pads and brake fluid, I will be leaving it stock for at least the first year. I work for a road course so it will be seeing a lot of use there. Having GM back their product if something happens is incentive enough for me to leave it alone. At least initially. I think I will be spending enough on tires and brakes anyways.

Excellent information! I have one question though… You mentioned a – street as the category it would likely fall into. I do not see that category listed in the information you provided. If you wouldn't mind could you please elaborate on that specific class? Really helpful post thank you

[BradfordCamaro]

What is there to do? I think GM Engineers know what they are doing. I'm not going to start slapping on parts and tell myself I know better.

This.

All day long.

There are 4 broad categories going from least modifications to most modifications, Street, Street Touring, Street Prepared and Street Modified. Each category has sub categories, so for instance the Street category has A-Street (AS), BS, CS, DS, ES, FS, GS, HS and SS (Super Street). All of the cars in those sub classes have the same rule set but cars are grouped together so that they are relatively close in performance. This way you don't have a situation where you have two cars both set up for the Street class rules like a Corvette Z06 running against a Honda Civic. The Z06 would be in SS and the Civic would be in HS.

Traditionally the Camaro has been running in F-Street (FS) against Mustang GT, M3 BMW etc. However due to the increase in performance expected from the 6th Gen 1LE we are speculating that it could get bumped to A-Street where the GT350 that the 1LE is likely faster than was placed. We won't know until they update the classing for 2017 though. Regardless of if it says in FS or gets moved to AS it will still have to abide by the same Street class rules if you want to run it in the Street class. If you choose to more extensively modify the car it would be bumped into another category for instance if you had a tune and wanted to run 40 treadwear Hoosier A6's you would move to the Street Prepared category sub category "E" or E-Street Prepared or ESP for short. If you wanted to also add a huge rear wing on top of that you would be moved to Street Modified or SM where all of the cars are placed together with no sub categories. (well there is SMF which is Street Modified FWD)

The best way to use the information I posted is to decide on what mods you want to do, then find out which of the 4 categories it falls into, then consult the SCCA Solo rule book to see what sub class your car would be placed into. If you are new to Autocross I HIGHLY HIGHLY recommend that you do not modify your car until you get a reasonable amount of seat time. I see tons of new autocrossers show up for events that have already done tons of modifications to their cars and wind up in some super competitive group where they have absolutely no chance of being competitive. Try it first stock, see where you fall out with your current skill level, work on improving that with more seat time or instruction and maybe get better tires and a performance alignment. If the 6th Gen 1LE remains in F-Street that is all it will need to kick the living crap out of the competition there.

Updated to add:

I went back to read your list of planned mods, and your Kooks headers and intake changes would put you into Street Prepared category, and spring changes that modify ride height could possibly move you into Street Modified but I would have to research that some more.
