    ATS Performance Mods - 3.6 AWD

    Just wanted to freshen up this part of the forum with my latest list.
    This list represents what I would do with my ATS if I had the money, not because I would expect huge HP gains or track improvement but because racecar.
    In order of buy and install.

    Group 1 (Suspension/Chassis):
    https://www.bcracing-na.com/product/...013-2016-fixed
    https://zzperformance.com/ats/suspen...-sway-bar.html
    https://zzperformance.com/ats/suspen...-sway-bar.html
    https://www.zzperformance.com/ats/su...ut-tower-brace
    https://www.zzperformance.com/ats/su...-trailing-arms
    https://www.renickperformance.com/co...-chassis-brace

    Group 2 (Brakes):
    https://zzperformance.com/ats/suspen...brake-kit.html
    https://zzperformance.com/ats/suspen...brake-kit.html

    Group 3 (Tune):
    http://getoverkilled.ca/ats.html (See Autocal)

    Group 4 (Intake/Exhaust):
    http://jacfab.com/products/camaro-pr...nifold-spacer/
    http://jacfab.com/products/camaro-pr...take-manifold/
    https://afepower.com/afe-power-51-74...-intake-system
    https://www.magnaflow.com/products?partnumber=15196

    Now if someone could go out and just do all of this for their 3.6 and report back I'd really appreciate it!

    Re: ATS Performance Mods - 3.6 AWD

    Good list!

    Don't forget the 80mm throttle body, also from Overkill, to go with the ported intake and manifold spacer.

    Also, keep in mind that the front sway bar on the 3.6 AWD has been anecdotally described as being "as beefy as the Eibach" 29mm RWD-only solution, so it may not require an upgrade to ZZP's 27mm bar, or Eibach's for that matter. Maybe the front bar on a 2.0T AWD is 23mm, as ZZP indicates? Interesting, but maybe not surprising, that the front bars for Camaro and RWD ATS are interchangeable...

    While you're at it, don't forget about the easy Camaro SS Brembo brake upgrade...lol...as long as $$$ is no object - because racecar.

    The only reason I chose to omit the 80mm TB is that it requires modification of the intake tubing. There is no bolt-on equipment available that will mate to the big bore TB, so you have to use a silicon adapter...
    I haven't seen any dyno results of an 80mm TB on a 72mm intake. I imagine the intent of 80mm is to have 80mm or larger intake tubing, otherwise you just restrict airflow and increase turbulance? maybe?

    I am also a believer in sway bar balance. If you upgrade the rear and not the front it may increase oversteer.
    The steering on our car feels almost dead center with a slight oversteer stock, so I would want to maintain that balance by upgrading the diameter of both sway bars.

    That's a reasonable take on the 80mm TB. Ultimately, it would deliver more air to the motor, which you could take advantage of especially if it's combined with other mods/tuning. Maybe the happy compromise is a ported 72mm TB? It would be easiest if you have a local machine shop that you trust, but it's available for purchase as well.

    You're right about maintaining sway bar balance, especially for a street car. If the front bar on an AWD is left stock (assuming 23mm, though it may be larger w/V6?), what's your opinion of simply exchanging the 14mm FE2 rear bar for the FE3's 19mm bar? The primary attraction for this solution is cost-effectiveness - the bar and OEM bushings can be had for <$100 - and it should make the rear handle a little flatter for an 'enthusiastic' daily driver. Increasing the diameter of the rear bar by >35% should be a noticeable improvement, I'd think.

    If the bar's dimensions, construction (solid vs hollow), and link hole locations are the similar, the increase in stiffness for the bigger bar will be waaaaaay more than just 35% - maybe even 150+% more for the FE3. I can't recall how the rear end felt when I test drove an AWD 3.6, but I'm sure going to the FE3 will make it a bit pointier. I'd say go for it! If you feel it's too much, then just put the old bar back in. Just be careful the first time you drive in the rain or snow, it will catch you by surprise.

    I'm sure this has been answered on the forums before, but does the FE3 bar fit the front of a 3.6 AWD?
    If not, I would go with a bar designed to fit my drivetrain.

    A great option for people with a lower budget! I think I will still get the zzp

    There isn't an AWD ATS w/FE3, so no, the front FE3 bar, as well as the Eibach front bar, are incompatible w/AWD. If you look at the front RWD and AWD ZZP bar pictures, the AWD bar has a little dip in it - assuming to accommodate the differential.

    My thoughts, exactly!

    Re: ATS Performance Mods - 3.6 AWD

    I would be very interested to know if anyone's swapped out their rear sway bar on an AWD Premium. I've got a 17 AWD Premium Luxury, and I think the back end gets a little loose going around a cloverleaf, even at exit ramp speed. I feel like the back end just has a little more body roll than I'd like.

    Solid List of Mods, Stiffer ride ride, better handling and decent Horsepower Boost for a NA engine.

    Re: ATS Performance Mods - 3.6 AWD

    So my buddy works as a marketing analyst/specialist with K&N.
    I'm going to jump my planned order and move straight to Stage 4, lol.

    I will post and update with pictures and a youtube link.
    We will actually be doing the installation at K&N's offices with their marketing staff.

    Stay tuned (pun intended)

    So are you planning on installing the AFE intake or a K&N intake? If you're doing the AFE, I'd be really interested to see how each mod changes the car. I've done the JacFab spacer and ported manifold and am wondering if the AFE intake would be noticeable. If you're wondering my review of those two would be an increase in torque between 2-4k (with maybe a slight decrease in the 1k-2k range, but with smoother delivery), then more power on the top end with power delivery cleaned up and more linear feeling throughout the entire rev range. I'm pretty happy where I'm at now, but we'll see how I feel next summer - the ported 72mm TB and the AFE intake could be a fun thing to keep things interesting!

    I'm going to go with the K&N for the sole reason that I have a connection with them and they're going to film an install video on my car. Otherwise, I would probably have gone with the AFE as it is a much more polished looking system.

    Re: ATS Performance Mods - 3.6 AWD

    So has anyone done an FE3 rear bar only on a FE2 AWD 3.6?? Would be really interested as OEM upgrades are the only ones I'll be doing other than a custom exhaust on my new 3.6 ....

    Bump? .... FE3 rear bar on an FE2 3.6 AWD with presumably an already bigger front bar than a 2.0T AWD ....

    Would it become uncontrollable at speed? .... All's I want is to remove my initial understeer .... Tires all at 34 ish psi ....

    It could be that you'd be the first to do this, I'd say go ahead and take the plunge! I highly doubt it would ever be "uncontrollable at speed". Will it change the response and balance a little bit? Yes, and you will adapt. From a quick search, I think your (incorrect sizes - see edit) FE2 is a 23mm diameter rear bar and the FE3 25mm - that is not a huge increase, guessing around 40-50% stiffer (you have to know a lot more about the bar measurements to figure this out for sure).

    edit: FE2 rear is 14mm and FE3 is 19mm - that is actually a pretty big increase, like probably around 150% increase in roll stiffness. Now the low-traction rear suspension compliance with my car vs the loaners I've had makes sense...

    It'd be a subtle change, but do know that it will probably reduce stability a bit in the snow (looser rear end) - BUT remembering the 2.0T AWD loaners I had compared to my RWD FE3, your car with FE3 rear sway would still be far more "winter-able" than my car. One other thing you may want to do at the same time is replace your rear sway bar end links, but that is another can of worms to research.

    TLDR - Buy it, install it, love it or list it.
