Are there any difference between all the brand selling a CF side diffuser? Or are they basically all the same, just a flat piece of CF as a side diffuser, any experiences with the VISRacing ones compared to downforce or any other brands?

 

Any ideas?

 

I have the vis ones. I don't know anything about downforce but the vis fitment was perfect and they look really good on the car. There a little more than just a flat piece of carbon. Def a good mod. One side benefit if you have low offset wheels they help protect the door and front fender from rock chips.

 

the VISRacing ones are just MSRP at a higher price, but I'm pretty sure vendors can get you a better price then downforce. I believe the downforce ones are actually like $450+ shipped for a set.

 

I have no experience with the VIS ones, but I do have the Downforce ones. The DF ones are molded to fit all the little contours under the car. They fit exceptionally well and look great. I would highly recommend the DF ones if you're looking for side diffusers.

i just ordered mine, i can't wait till they show up

 

I have no experience with VIS products, but I have the Downforce fenders and they fit perfect so I'm sure the diffuser would too.

 

do you just install with screws? double side tape? both?

 

I have VIS ones, they fit perfectly with no modifications. I had it double side taped and self tapping screws. I think the weave is slightly different on the DF compared to VIS (with DF being better) from another s2k owner who compared the 2.

 

for DF side diffusers. Perfect fit and good quality.
