Nissan GT-R ALP Front and Rear 2 Rx + 1 Tx Placement

[Spindrift]

I come to the RDF well of wisdom to drink the sage advice within. I am planning a 6 head ALP install on a GT-R and want to run my proposed set up by the community. Below are dimensioned shots of the layouts I am thinking (didn't feel like taking the car out of the garage to get the rear shot, hence the stock photo):

R_D1 =Ground to bottom ledge
R_D2 = Ground to top ledge
R_D3 = Rx center to center measurement
R_D4 = Rx center to outer taillight center
R_D5 = Tx center to outer taillight center (layout 1)
R_D6 = Tx center to outer taillight center (layout 2)

The trunk pop button lives in the center of the top ledge, hence the second layout for the Tx head. Also, here is a top down view of the rear to show the profile as I believe the extreme curvature could drive placement and off angle performance:

For the front, the placements look as follows:

F_D1 =Ground to bottom ledge
F_D2 = Ground to top ledge
F_D3 = Rx center to center measurement (Layout 1)
F_D4 = Rx center to center measurement (Layout 2)
F_D5 = Rx center to outer headlight center (Layout 2)
F_D6 = Rx center to outer headlight center (Layout 1)
F_D1 = Tx center to Rx center (layout 2)

Again here is a top down and side view to provide some context to the front end curvature and the protrusions around the area:

As always, any and all advice is appreciated. I will be performing the installation myself and intend to document the process for a build thread when the time comes. Of course, the cleanest install in the world means nothing if not tested so once done, the car will be vetted with @thebravo and the rest of the folks in SoFlo!

Vortex,

Thank you for the kind words and vectoring me to that install, I thought my google-fu was good but not good enough apparently! Thank you as well for all the information and time you put into this community, you have definitely been a driver in my decision to dip into the CM world!

Smason,

Thank you for the response as well!

Sweet ride! Hoping to get myself a GTR one day!

I love the DBA styling, but I'm on a cba Budget

Welcome. Oh man, my dream car! Do another RDF search, Jon at Radenso has a GT-R with a stealthy ALP setup.

In all honestly, they are pretty much the same underneath mechanically speaking. Even more so when you throw a tune on them! I wouldn't hesitate to grab one. the '09-mid '10 had some dodgey transmission seals, but the late '10 and up are good to go. The DBA will be slightly more refined, but the CBAs are great cars as well!

Sweet side! Hoping to get myself a GTR one day!

Thank you for the kind words! The older ones are coming down everyday, I wouldn't hesitate to grab one when you can!

Jon's ride was one of the inspirations for my build, however I'm not going to throw $11k into the system (per Vortex's video)! Always dig the DIY approach a bit more!

Ha ha, ya suggested Jon’s just for placement ideas...

Copy all. I based the layouts on his car, I was not sure if having the rear Tx sensor that close to the Rx sensors would be an issue as I think he runs Rx only in the rear. I guess it would be interesting to see if Jon's front Tx has any issues being mounted below the 20" minimum distance.

I have not looked a Jon’s install for a while but recall he used perplex to hide some heads for a stealthy look...

Jon has a VW Golf R, not a Nissan GT-R

I'd really like to incorporate perspex covers with adjustable 3D printed housings to the build. Those clean installs seems an area ripe for some DIY love...COVID makes people to crazy things sometimes!

But does his Golf R have arrows? /s

The minimum recommended distance Rx to tx is 7 inches I believe, though I think a few folks with mustangs have gone a little smart without issue. And we are glad to test you at the south florida testing group

Thanks Randy, my bad. I just remember seeing a GT-R with Radenso on it...customers?

Bravo,

Thank you for the SA, sounds like the rear set up will be GTG. Hopefully I can have something sorted for the winter meet up!

@Spindrift - can you please post pictures of where the various sensors ended up being installed? Any lessons learned? Looking to do the same thing on my GTR...

Is the back end of the GTR too wide for 1Rx/1Tx?

With the Tx not having any Rx capability, I think there could be a blind spot if you rely on only one Rx sensor. This coming from someone wholly unqualified to give any real world advise on the capabilities of the system as my isn't even installed yet so bear that in mind.
