Hi all,

Anyone know of good aftermarket diffusers for the 4.0's? Lots of support out there for the center-exit tips but what about split exit variant? Looking for options.

Thanks!

Hello, I am a new member, but I have been following with interest for awhile.
I have communicated with Suncoast to see if they would but together a kit of OEM Porshe parts to put a GT4 rear diffuser onto a GTS 4.0.
They have:

• GTS 4.0 Rear Diffuser UpgradeSKU: PK71840DIFFUSER
  No reviews yet. Write a review.
• MSRP $2,200.83$1,695.00

Why would you want to place the wrong diffuser on your car?

Understeer at speed! Who doesn’t love that?

I guess because it looks cool and seems rather inexpensive. Sounds cool to me, but people might want to also reduce lift in the front along a similar curve (lift/speed)

Ultimately, I find the factory GTS 4.0 rear diffuser to be pretty lame and adding a working one that is OEM is appealing to me. If I did upgrade to the GT4 rear diffuser I would upgrade the front bumper/spoiler as well to keep the balance.
This would basically mimic the aero setup of the new Spyder.
