I researched them and didn't hear good things about them.
I did however ano the stock tubes. If anyone is thinking about doing the same dont try. The threads on the tubes got pitted beyond use during the process.

I do plan on using some model paint on the exposed parts of the tubes or not depending on the ride height I have to use. Going all black is fun but I dont want to loose any quality of function. I will be racing it this spring.
