@Zygrene Motorsport AOS was $723 in 2014. Labor was the killer: 14 hrs = $1,890. But BRR said only a couple hours went into the actual modifications to make it work; most of the labor would've been required just to replace the OEM AOS with the same unit. I rationalized I'd never have to pay to replace an AOS again, and I haven't so far. About 75 track days since 2014 and the Motorsport AOS has been a stalwart -- not a whiff of smoke, ever.
