They do offer that support. You can get a map from Terry, but it's usually garbage. That's why people pay Jesse. I've seen the logs from some of the Terry tunes, they're not... amazing.
Yeah, it's all subjective for sure! Some budgets are bigger than others, so it's hard to say. I'm lucky enough to where 3k doesn't break the budget, others have a tighter budget.
¯\_(ツ)_/¯
Honestly, with how rare they are right now, I wouldn't go less than 8k for the set. I've had offers close to that.
The best bet right now is to just load up on stock axles. Snap one, swap it at the track in your pit, make another hit.
Flashed it. My arms are too stiff from the insane sunburns I got at the track yesterday to even attempt to go outside until the sun goes down. I'll report back tonight.
