I meant to post this in the "removing the wing" thread, but I guess it applies.
The way I look at the base and limited disrupter and SRT6 wing is style. The concept is to disrupt the air flow over the wing shape of the car to reduce lift at the rear end.
Does the disrupter or wing have to be so big?... no. it's style.
I've got a ity-bitty disrupter on my SLK32 and it works great up to the limiter.
Note that the SLK style is much more squared off in the back unlike the Crossfire which swoops down in the back. Each of these body styles alters what kind of downforce device they need and how large.
There is no place to put a 'Gurney flap' on a Crossfire... none.
The SRT6 wing stands over 3 inches above the rear deck profile at it's highest and only about an inch at the lowest to catch the air stream that is following the body line and use it to push the rear end of the car down.
The 'Gurney flap' that you have on your SLK does the same thing, BUT, it only needs to be small as the air has already been hitting the trunk area and needs just a little more 'push' on the tail to give sufficient force to keep the car stable in turns at speed.
If you want to get a bigger wing or different style of wing, be my guest. If you want to do away with it on an SRT6, make sure you have your Will or Living Trust in order.
