Do I need the front tow hooks on?
ie. do they need to attach braces to my hooks?

 

yes

 

I have had my car dyned several times. They have never used mine. But every place is different.

 

every place that i have dynoed ties it down with the tow hooks

 

they should.

Usually Use 2straps in the back and 2 to 4 in the front.

Last thing you want is the car coming loose with a whole bunch of people standing around

 

here's some pics of my car on the dyno a while ago..... this is how most of the dyno's are that ive seen. hope it helps. sorry pics are crappy

 

They don't need to use your tow hooks....most dynos have U-straps that can attach to your control arm. I had to take my drivers side tow hook off for the charge piping with the turbo kit, and they used the U-strap on that side to attach the tie downs to.

 

Thanks for the info guys.
I'm going in on thursday, i'll let you all know the results.
