I'm having my gts windows tinted using photosync at Premier in Fremont,Ca.
Per our conversation they are recommending the following tint percentages,
Windshield - 75%
Driver and passenger front windows - 55
Sides and rear - 75
Pano - 35

i'm good with all except the sides and rear, I think maybe 65.

If you use or used this product Please share your experience and thoughts on the %.
Thanks!

 

No experience with that product, but I did have my 16 GTS tinted using LLumar.

My back doors and rear glass were 37% from the factory according to a light meter.

If you tint those with a very light 75% film, you probably won't see much difference, it would bring them down to around 30-32%. (Using a 65% film would get you to 30% or better.)

For the front doors, I'm guessing you are working to comply with a legal statute mandating 50% by using 55%. Otherwise, you could use a 35% film, which would bring the fronts down to an actual reading of 32% or so, effectively matching the rears.

 

Given that the stock tint is at 35% (that's what my 2016 cayenne s ehybrid measured to be at Rocky Mountain Window Tint in Livermore using a light meter), Premier likely recommended 75% tint to bring the overall light transmittance to ~26% (0.35*0.75). The 25-30% is the OEM light transmittance found on most cars with stock tint and provides the best tradeoff between privacy and visibility at night.

If you have a light interior (mine is the standard beige), it will still appear too light. I went with 50% pinnacle formulaone ceramic tint on my rears (bringing actual light transmittance to 17.5%) and thought it still looked too light, but in reality when driving at night, I would not feel comfortable with anything darker.

Hope that helps.

On a separate note, I also did research on the photosync film and didn't think the huge price premium for photosync was worth the few extra % points in heat rejection performance as compared to Llumar Pinnacle Formulaone ceramic film. The difference is imperceivable; the biggest gain is from simply having ceramic heat rejecting film on the window.

Also, I have seen both Premier's and Rocky Mountain Window Tint's work, and thought that Rocky Mountain did a much better job with the dot matrix; the original owner always does all the work himself. On the front windshield (I have Llumar Air 80), rear quarter panel windows, and rear liftgate window, there is no silver looking border from the dot matrix; the film is bonded perfectly to the edges of the dot matrix circles, preventing silver outlines.

 

I have the Spectra tint on my CTTS. For more details, see the link in my signature.

• Front Driver / Passenger Windows - 45%
• Front Windshield - 75%
• All Glasses Behind Front Doors - 65%

 

Typically, there is some loss when applying tint over tint. The straight math doesn't work out to the actual light transmission.

So, applying 50% over 35% tint gets you to something in the low 20's in practice.

 

Thanks for the tip...Next time I'm in the area, I'll stop by the shop again to get an exact measurement

 

Thank you all for your replies!

I have been pouring over tint specs, images and information provided here on 6speed and facebook. I also made a couple more trips to Premier and I think I have figured out what is right for me.

I just like the look of Spectra Photosync over the other manufactures film and have decided to go with the following %
Windshield 75, front windows 55, sides 75 and rear 65.

I'll post a couple of pics after the installation.

 

75 is almost clear - I recommend Quantum for the windshield. Running 28% on the windshield of the daily drivers. Its CLEAR on the inside and provides fantastic privacy and reflection from the outside. Its designed for windshields.

 

My car meters out to 16-17% all around, with the exception of the windshield.

 

Here are some cars done with Spectra PhotoSync:

LaFerrari - Photosync 75% on windshield / 65% on the sides

Red 911 GT3 - Photosync 75% on windshield / 55% on the sides

 

I used spectra as well. My front windshield is 40. I wish I went lighter due to having black leather. It just looks to obvious that I tinted the front shield.
