Cooling Upgrades - 2012 vs 2013




Coming from an E55 and cooling issues on these cars, my question is this:
- Is the 2012 with the upgraded and split cooling (Wesitec seems to be cheapest at $1,999) better than a stock 2013 system or roughly the same?
- Would a 2013 with a better intercooler be any better than a 2012 with the Wesitec kit?
AMS seems to have a nice kit but its $3,259 with the divorced cooling. HOLY smokes. Even the Wesitec kit is extremely expensive in my opinion but...
Take the poll, I'd really like to hear you guys out.
PS - sorry for the typos in the poll, cant figure out how to edit.

I have a 2012 with stock cooling and have taken my car to quite a few track days and autox events. 2012 stock cooling is 100% fine.
If you're doing back to back 1/2 mile runs I could see it being an issue, but you aren't doing that.....
Get a 2012 and use the money you saved for a tune and you'll thank me later

Again for what 99% of most people use these cars for the stock 2012 cooling system is fine.
Anything you do after that will lower your IAT's but you won't see much if any improvement unless you're that 1%'r

even on my 2014 (2014+ has additional exchanger) tuned, i notice a decent difference between 60f day and 90f day, so the better the cooling you can get, the less timing your gonna pull
somewhere on here i think dbasson split the system himself and had logs of the difference before and after and it definitely made a difference

So i think a 2012 with the Weistec kit (bigger IC and split cooling) should be good to go.
Now gotta go find a 2012 around NY without a million miles that doesn't cost a fortune.

In short
It would take quite a bit of abuse before any drastic power drop off like the E55.
My car has been tuned with full bolt-on's (tune,dp,plugs,filters) for roughly 5k miles. I daily drive it and it has seen 100+ degree temps and has yet to feel sluggish. I've done back to back 130+ pulls with a couple of friends and it never hesitated. I cannot say the same for my old stage 3 E55. After about 3 pulls I could tell the temps were getting to that quickly. Even with a tank in the back.
I'm going to wait until my warranty is up completely and get myself the AMS cooling kit (mainly so I can retain my spare tire unlike weistec's kit). I will do the divorcing of the cooling system then with what parts are included.
