Ahh brings back memories of my 94 scort. I think you'll be happy with 20% tint. I had that on my black sedan Focus. Lowering kits are rather inexpensive if I remember correctly. I also did the same with my steel wheels.
I used a CherryBomb Glasspack on my scort. These were back in my highschool days so forgive the jerry-rig looking job.
