Secondary radiator install
The install went well.
Results for similar driving conditions and ambient temperatures showed a repeatable result of 12 degrees cooler oil and 20 for coolant. I have not had a chance to test this on the track. Car is a 7MT with level 3 aero.
A few notes about the install.
1) You do not need to remove the fender liner.
2) The hose routing per the instructions results in kinking the return hose. Routing it around the radiator support provides a nice and clean install with no kinks or wear points.
3) While I did not remove the front bumper, I would suggest it. Not needed, but much less hassle in installing the brackets for the radiator.
4) There are no instruction on what to do with the foam piece. The template provides holes for you to drill, but no hardware. I used plastic retainers that worked well.
5) The lower plastic assembly had minor interference with one of the raised ribs (the one smaller secondary rib). I decided to cut and sand this off.
6) For cutting the plastic, I used a dremel and cutoff wheel. It was clean, quick, and easy. The leading edge towards the front of the car is the functional edge used for support. The cleaner you can cut this edge, the better your install will be.
While the price on this part is high, the results were exactly what I wanted for my first cooling mod. My normal hard driving in 90 degree weather would put my car at 220 oil and 220 coolant. Temps would go to 230/230 after a few redline pulls. After install, under the same conditions, I see 205-8 oil and 195-200 coolant, with 212/210 after several redline pulls.

Nice review and write-up. I wonder what this plus an upgraded OE radiator may net. Is there any "official" statement about either/or and warranty? Since it's from GM, I can't see how it would effective negatively.

I was parked next to an automatic that overheated about 10 minutes into every session....

Nice! Are you A8 or M7? Also, any log or info on IAT's with this mod? (ie. does it block and airflow to H/E?)

My Z is up in the air currently right now, so might be a good time to tear-down the front end. Who had the best pricing on this?

Nice, I've got the 17 M7 on order, and have a question into my Dealer as to weather I can just order the car with this additional Rad from the factory...
Any Thoughts??

17's may have a completely different cooling package. Just wait and see. Your dealer doesn't know anything right now.

M7 (As this resides in the same spot used by the A8 for a transmission cooler.) I logged IAT's, and they were unchanged as expected. The HX circuit uses a different cooling loop.

2d radiator install
never mind. i just saw why my Z has one already. auto. thankyou anyway.
i just goot here but am wondering. my 15 Z has an extra radiator already installed. am wondering what year and model you added this to. why did yours not come with one as mine did. just wondering because im confused as to why my z came with one and yours did not. thank you for your patients with an ignorant computer user. i am having problems getting around on this forum.

Hey guys, any other tips on installing this thing? I'm doing it this weekend. Where does the foam thing end up going?

You can see the foam in the last picture. It basically is a cover for the hardlines and connection points. It sits on top of the secondary, all the way towards the main. PM me if you need any help.

I liberally used wire ties to hold the lines and foam piece in place.

It wasn't perfect, and I also had to drill my own holes for the clips. Just make sure the leading edge is cut straight and square.

Getting to installing mine this weekend too. Got delayed due to installing my 4-post lift first!
