i found this post

which shows the air dam brings it very close to the length of the mazdaspeed side skirts in relation to the ground.

How much closer does the air dam bring in comparison to stock as far as height to the ground

meaning how much does the air dam add onto the bumper in length. I want to put on the racing beat side skirts, but i want to make sure it lines up closely.

 

anyone know if this has th same height as the RB sides

 

Here's a link for you. We have 3 winning blues lined up ... mine that's stock, Admiral8 which is the front airdam and SlowLude who has the MS kit. As you can see from the photos, the airdam and the MS bumper are more or less the same height. Compared to stock, front airdam is approximately ~0.75 inch lower (from what I remembered)

As to the RB side kit, never seen any comparison pics of it with MS or stock, so can't say.

 

this helps tremendously. now i just need to find out how low the side skirts are from the RB kit
