does anyone know if the rear spoiler improves fuel economy or makes our xbs go faster??

the whole function of a wing is supposed to sit the tail end down when the air blows over it hence giving the rear better traction....the problem is the xb is fwd and thats where i am also confused as to if it has any advantages(besides looking cool) at all. from my understanding a fwd with a spoiler....the spoiler is useless or just a dress up

It makes a great towel rack when washing the car

AT least 10hp, especially when you put an exhaust tip on it bumps it up to 15hp.

its job? look pretty

joanthegreat

wow! what worthwhile upgrades! the tip must enhance the exhaust flow tremendously

joanthegreat

since i have no other reliable evidence to the contrary, then this seems most likely! thanks!

some spoilers divert air over the rear window to blow dust and dirt off

If you add some NOS stickers, you'll dyno at least 150 at the wheels

Bingo! This is the correct answer. Since the wing does not really deflect air up, it doesn't add to traction. Some air is deflected downward to prevent dust from being caught up in eddy currrents and collecting on the rear glass.

But looking cool is an excellent reason enough for me!

I thought it was there to hide the window squirter.

This seems like the most logical answer...

joanthegreat

the window squirter's cute. why would anyone want to hide that?
