thanks in advance

It is cannot be used after installing the splitter.

Rear diffusers are a great way to add downforce to the rear of a car. The other option are wings. Both have their positives and negatives.

and what are those ?
How about adding wing/spoiler and rear diffuser at the same time? Would there be too much of penalty (air drag)? Maybe I should simply start adding the splitter and diffuser first then take it from there



Btw, I actually would love to get rid of that heavy plastic part so it's a win win for me

very interested in this. my car will be dd/ autox and the occasionally track day. however i also live in an area with snow and i will be driving it in the snow. how will this hold on in the snow? do i have to take it on and off throughout the year?

Rear diffusers, when properly designed, can generate A LOT of downforce for little drag penalty. However, given most street car chassis setups, a proper designed diffuser is near impossible, making them less effective (I am NOT saying they do not work). Wings create massive amounts of drag per pound of downforce. However, they are less vehicle/chassis specific because of their placement and that makes them a more repeatable way to produce downforce.

I would start with underbody aero first, but that's my personal preference.

The material will work fine with water/snow and should actually hold up better than fiberglass or carbon fiber. Both of those materials splinter and crack where this material will not do that.

What would be your input when combining this front splitter and maybe a rear diffuser with something like a wing or big spoiler?

and to the link the spoiler I am considering

I would personally do the splitter with the Driveway Labs diffuser and see how you like the car. If the car oversteers greater than what you as a driver are comfortable with at high speed (many people like cars setup differently), then I would look into a rear wing. I would not do the rocket bunny spoiler. There are some good wings out on the market and some bad ones. Do not believe the numbers thrown out by any of the companies as they do not apply unless tested on these cars. I am also not a fan of the 3d profile, unless it was designed for a specific car.

I agree with this. Underbody is more tricky to create downforce, however it doesn't come with the large drag gain that wings do. Being that these cars are very underpowered, I would only tackle a wing if you can't make the downforce in other areas.

That good to know. What if I had to drive through I plowed area and snow collects on the spliter?

It is not a snow plow so if treated like one, you could see damage to it or your bumper. However, it can handle some snow just collecting on the top side of the splitter.

that's what I am planning to do,
Do you think that adding rear diffuser and splitter increases the oversteer? or do you mean that if I still have the oversteer after adding those?

I am also pretty skeptical about the functionality of the many aftermarket parts. Btw, what exactly do you mean by the 3d profile?


How about a trunk that already has a built in spoiler that looks more functional than the OEM one?
something like this




AFAIK, with the spoiler extension there is no drag penalty like the wings, well at least it works great with the new Camaro Z28s but then again it may be because it's designed for the car



how would you compare the wings to the duckbill trunks ?

Thanks again

A rear diffuser should reduce oversteer as it is adding load to the rear wheels.

Too much aero on the front makes oversteer. Too much on the rear makes under steer. You've gotta maintain a balance.

If I still have the oversteer that is uncomfortable after adding those (splitter and diffuser), then maybe look at adding a wing. I personally like a car that has slight oversteer.

You should be skeptical of a lot of aftermarket parts. Many in fact do the opposite of what they claim.

A 3d wing profile is one where the profile changes down the cord length.
3D profile is below:

2D Profile is Below:


Spoilers work and work well. However, they won't create as much downforce as a wing(properly designed of course), but they usualy create less drag. Deciding between the two or any at all should be determined after you do the other mods and see how the car drives.

I will be having an analysis coming out soon on this splitter paired with the V1 diffuser from Driveway Labs. Hopefully soon after that, I can have one also with the V2 diffuser. This should help people have an idea about how their aero will effect the characteristics of the car.

^ much excite. So anticipation.

2 weeks maybe. I have a few other things I am working on.
