Hey there, thought to pm you on your request since it could otherwise clutter up the forum off-topic.

Is my research file in regards to 19 and 20" wheel and tire combinations that could fit, with a goal of reducing weight, and increasing track width. It isn't every single wheel out there and there is the variable of caliper clearance, but it is a pretty big list with slicers to help narrow down and I've done my best to find actual wheel weight for almost all of the wheels. My top budget in the sheet is about 500 a wheel (Enkei Japan and SSR options.). All of this is from a perspective of an AWD, square setup.

Money no object 19's: Enkei GTC02 or Weds SA20R (still not terribly expensive)
Alternates: Motegi MR158, MRR GF5, Konig MRK1, Advanti Hybris

20's are also on my list, but might be a harsher ride than I'm ready for. Still on the fence.
