im on the same boat as you. i thinking doing 35% on my fronts. but i dunno if its too dark.
i dont wanna get pulled over by the cops. my other friend has 50% on the front and its ok look where it looks kinda dark and probably wont get pulled over.
but i have 20% on my rear 3 windows on my other car i have and its pretty dark.

so post pics what 35% looks when the s2k is outside Thanks!

 

sorry, but that is not tint. just joking. heres some pics of mine.
complete front 35%
sides 5%
rear 15%

 

^not a fan of the front window tint ...the 35% on the S looks lighter because there is a good deal of light behind themm being that its only the two front windows, the light coming in the front windsheild makes it seem a lot lighter. I used to have a Type S with 20% all around and that seemed way darker than my S (LBP) which has 15%

Just my .02 tho

 

Here are some of mine with 20%.

 

Damn I need to get my car tinted.

 

Correct, it really depends on the angle you look in the widows. If you are standing next to the car and look in the side window you can't see much with 35% because you are looking down at the seats and console which are black. Then again, if you look at an angle where you are looking through the side window and straight out the front window it's not nearly as dark because of the light transfer. You can really take tint pictures at 20 different angles and they will all look different.

Bottom line is it looks good and keeps the sun out of my eyes when the top is up.
