XRAY - Model racing cars

I've just finished my MST drift build and I'd like to start building my on-road "built for speed" car. I'm not looking to build something insanely fast, but I want a really nice and fast car to play with on pavement.

So here is the build I'm planning so far:

XRAY T4 (2016)

LRP "Flow" ESC

REDS Racing VX 540 Sensored Brushless Motor

SRS4210 or SR410 Receiver

What do you guys think? I'm also wondering

What turn motor should I get? I want something fast, but also that isn't going to put too much stress on my car (The reds motor comes in several T options, so any advice would be great)

Does the Spectrum AVC tech add much benefit? I run a SR410 on my drift car, and it's great. Wondering if the SR4210 is worth it.
