Ive been looking for a rear diffuser, this may work.

 

mods, meant to put in 3rd gen..please delete

 

whats the benefit of a diffusor?

 

looks? more weight on the car?

 

better aero. i think it would look good.

 

i think it would be a waste

 

The s2k in the pics look nice.

A diffuser, in an automotive context, is a shaped section of the car underbody which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand so that the boundary between the car's airflow and "external" airflow is less turbulent. It also provides a degree of "wake infill" (the wake being a turbulent area of low pressure that is caused by the passage of the vehicle through the air; this can cause pressure drag).
It works to bring the low pressure air below the car back to the ambient atmospheric pressure without inducing turbulence. It uses Bernoulli's principle, such that the pressure increases while the velocity decreases. Since the pressure below the car is lower than on the side and above the car, downforce is produced if implemented correctly.

basically it's a whole lotta math. creates downforce and regulates turbulance of air coming out from underneath the car

 

yup, what razzi said. i also heard that it helps stability at high speeds

their is a member with a white super charged with a FMIC. he has the rear diffuser and some front bumper splitters. it looks sick on his car.

 

Damn.. OP's just got money to burn

 

Looks like Thomas (<-- that's me) is going to head to the hardware store this weekend... doesn't look to hard to build....

Will post the DIY after it is finished....

 

so thomas, u got a 3rd gen or 2nd gen tl? if second gen im gonna have to look into this as long as its functional and cheap/easy to do.
