ring and pinion ratio suggestion

Lol, guess that explains the user name! No Apologies needed, most of us like details, it's all good! I guess You have to decide if You want to go 3.54 & live with the car
sitting 3/4" higher if You feel it's too much & do the 16" rim switch. Plus, not certain of the options in each size to You, also a consideration. 27" looks like a tight fit on
that car, how much room will that leave you? Neat ride BTW!
