Hi folks - first time poster, long time lurker. I'm taking delivery of a new P90DL next week, and want to get an opinion on wheels. I'm deciding between 20" HRE S107s, and the 21" TS115's. The car is obsidian black, and I will probably get something like a gloss nickel or grey color. Does anyone have experience or opinions about these pro or con? HRE I know would be a great choice, and I actually prefer the 20" to the 21", but the wheels from Tsportline look very nice and nearly $4k cheaper.
