Wondering what kind of aero people are running, and if someone has some experience if they actually do anything for performance, or just add weight.

 

Would a roof spoiler count?

 

I'm curious to see if anyone has done anything to add to the lower rear portion of their cars. Aesthetically, I feel that putting a front lip on adds to front aero but leaves the rear of the car a bit lacking. The only thing I can think of is a rear diffuser but I wouldn't want that on a daily. Maybe its just me but I've been curious to what others think and see what others have added to rectify. Anything but a full body kit of course.

 

Here's my aero set up diffuser, duckbill spoiler, side aero, plastic undertray and aluminum undertray. 626 lip and oem window visor.

 

Gp rear half bumper and shine auto skirts

 

While cool, that is styling not aero improvement. Doubt the rear bumper is doing much in regards to adding downforce or reducing drag.

 

Well unless you're going 100+ mph, you're never really going to notice any of these VERY minor aero "upgrades"


In theory, a full GP kit(or the like) should definitely help(drag coefficient-wise)

Even the S4 "sport aero" packagetakes a little off the top. I think it chages the coefficient from .30 to .29, but don't quote me on that.

If you're really looking for some aerodynamic ****, that actually works, you need


1: A good quality diffuser



2: A nice big wing, for some down-force.




3: A stiff/good quality front bumper/side skirts.






ALSO! If you're REALLY REALLY trying to get the best possible "aero" you can always go all ******* crazy like the time attack guys do. and get a bunch of this ****. hahahaha

Last time at the track i had entry speed into corners at around 140km/h on street tyres, so with slicks and more power, i will probably have an entry speed that will take use of aero improvements.

 

Heres my vert with a AIT kit. wheels: 25mil spacers all around, 17x8.5 w/ 225/45/17 in front and 17x9 w/ 245/40/17 in the rear.
PIC 1: Before PBM comp coilovers.

PIC 2: After PBM comp coilovers. NO SPACERS

 

The wing is it for aero so far... Needs to be raised to be effective.

 

Made a huge difference in traction while cornering above 60. Also slowed my 1/8 mile trap by 3MPH. Front splitter will be made this year.

 

What wing is it?

 

Wow radio what width rims are you running to have a tuck like that?

Wish I knew, bought it from a local corvette guy.

 

17x10 +8 front and +10 rear lol
