New Z owner from central OH

[Ivary]

I have been on this forum a lot over the past year in anticipation of getting a Z. Just last week I traded my RX8 in on a 2011 graphite touring sport pkg with smoked wheels and 6 speed with 23,000 miles.

I hope to get some mods soon. One of the first is an exhaust, when test driving Z's one of them was so loud my ears were ringing, not good. I am looking for recommendations that won't break the bank, or my eardrums.

Wheel spacers, especially for the rears, is 20mm too wide if I someday put a taller tire on it? If I space the front do I need a new alignment?

I drove one with stainless brake lines and really liked the improved pedal feel, definitely doing that one soon.

I am putting in a backup camera today, thanks to you DIY forum.

Thanks for having me as part of your community
