Back when I had a Mk3 Jetta VR6 I ran 20% tint and while it looked cool and cut down on the heat, it was a pain to drive at night. I think because of that I never got my windows tinted for the B5 S4, but with the B8.5 I really do want to happy medium.
So my search of a good tint shop around the Redmond or Monroe, WA area has started. Seems like going with a ceramic tint at 35% would be the best of both world for both, looks, heat reduction, and most important viability.
If you got any recommendation, comment below.
