I have been looking to get stance coilovers, XR1 but saw a set of GR+ with 12k miles on the boards for less than half the price. I know GR+ are "old" technology, but for the price does anyone know if there is that much of a difference between the two?
End goal is a clean snug fit, not slammed and eventually Stance Aircups. I don't track but do drive aggressively on the windy mountains around my house.
