So since I recently re-acquired a w-body, I've been scouring the dark recesses of the internet for 3800/4T65e performance parts. I see that Milzy motorsports is now producing a 1" gear set for the 4T65e. Priced at $1850, it isn't exactly cheap but at least it's readily available. Unlike the unicorn fart GMR 1" gear set.

Wondering what peoples thoughts are on this.
