So this is my car, I bought it from EG69 and its a solid car. It's pretty fast, there is a lot of quality parts on it, and the suspension, all I can say is ooh baby. Performance wise, this thing is top notch so I can't really do much but clean it up a bit. It's winter here, and the car is just sitting in the garage. I would hate to waste this winter not doing anything to the car so, I'm thinking of doing a few things. I would like some feedback just so I know I'm going in the right direction.

I'm taking the brake calipers and most of the OEM suspension stuff and either painting it or powder coating it black. I would love to powder coat it but I don't know how expensive it is. Can anyone give me a ruff estimate?
also I'm thinking of re-doing the wire harness this:

This picture is from reynardmauricio's build thread and I would like to do my harnesses like that. Does anyone know what he is using? Or just in general some more info on wire harness stuff?
Also, I'm thinking of venting my VC like this:

Not the chrome, but the two fittings on the side. Is that necessary or is what I'm running good enough?
(this is what im running)

The little fitting next to the oil cap goes to a catch can and the catch can goes to a endyn breath kit thing.
I also think that making most of my lines with earl's SS stuff would look cool, but is SS stuff more for looks or function? What do you guys think about that? I'm trying to keep this track car inspired not show car inspired.
