I have a simple ?. I have all glass except the front tinted with 18% The care is all Shappire Black with all black trims and no rear chrom insignia) , but am thinking of making the front driver and passenger windows 35%. How will that set with the rest being 18%? All professional advice accepted.

Have to change for certain reasons like the stste law says so for inspection. I could not get a doctor give me a waiver. Even if I did get a waiver; the night time is tough to view the rear view mirrors with the 18%. Is there anything else I should consider or just do the 35% with the 18 at rear? thank you Fellow Bimmermen. Dan
