Well, I don't have their kit in hand, but based on my homebrew setup currently (2.5" ducts from the fangs using Modshack's connection method, just dumping into the wheel well area), my guesses are:

(1) You probably do want to paint the front fang tubes. It's easy to do, just shoot them with flat black spraypaint meant for bbq grills before installation, so they're not shiny when you see them end-on (although you have to be pretty short to notice anyways).

(2) For oil cooler kits in front of the radiator, it should be a non-issue. Worst case you do a little messing around with hose routing. For the ones mounted off on the side in front of the wheel well... not sure tbh. It seems like you'd still be able to route this though, as it doesn't come through the *front* of the wheel well. Might just be a little tight in one spot?

(3) I don't think there's any concern about water, so long as you don't jam a garden hose into the fangs. It's a long and convoluted path, and what little gets through it would just vaporize on the brake side IMHO. Keep in mind your rotors are always getting wet in the rain anways, the outside is completely exposed through the wheel

Stillen: I didn't see anything in the product literature indicating the diameter of the tube and the end fittings. The stuff I've been working with to date has been 2.5 inch, but that's part of the reason I never reached the hub, it seems impossible to get a 2.5 opening to the inside there without closing off a chunk of it, and 2.5 inch hose doesn't play well in the wheel well either. Is this kit 2 inch, or even 1.5?
We went with 2" tubing. This was the largest tubing we could fit without requiring modifications to the chassis/body work when routing.

(3) Is there any concern with water making it's way through the piping and splashing the back of the rotor, which may actually negatively affect braking in wet conditions?
1) You pretty much can't see the inlets unless you're looking directly at them or trying to find them. Keep in mind they're only about 6" off the ground. I see our red 370Z which has been fitted with them and I don't even notice it when I walk by the car every day.
2) I don't see why this won't work with any aftermarket oil cooler. It may take a little creativity on hose routing but there is no reason it won't still work.
3) There is absolutely no concern about water and/or debris getting into the system. As Wstar mentioned, these go through a lot of bends and any debris or water will be stopped well up the line. Even if water were to somehow make it all the way back to the hub, it would not be a large enough volume to cause any issues.

Pics or BS

Thanks for your answers! Also, for those of us close to Stillen, how much to have you guys throw them on? I don't like bumper removal.

Not to derail, but bumper removal is pretty easy on our cars. I've done it twice now with no ill effects. It's a two person job, but only because you want to be careful when carrying it away from the vehicle and gently resting it somewhere.
