So guys. Have any of you seen this diffuser before?

Personally I think it looks nice af. Although it would look better on a dual exhaust car. What do you guys think? i know the mugen one is best looking, yet Every rsx in my town has that same lip. I wanna do something different. Or is it too different

Read through this link first; there's a lot of science that goes into a functional diffuser and how it works in tandem with other body mods. These readily available aero parts might actually be completely worthless outside of a car show. But you don't need power as much as to just be cornering fast enough for them to start working.

Also, if you do end up wanting the Top1 parts, be prepared for a wait. I hear 3 months to ship is common.

Not gonna lie, I'm tempted to get a full Top1 setup for my stock-engine base auto just to see if I feel a difference in the local canyons. The car's slow in a straight line, but I've got the suspension set up to where I'm already cornering pretty fast. My only worry is that with the Mugen coilovers, I might be sitting too high off the ground for the diffuser to properly work against the air under the car.

3 MONTHS?!? Jeezus [emoji33] I’ll buy the ebay dev sport instead maybe. & Thx for that link. I’m gonna read up on it soon. & I think the top1 is gonna be worth it. Since you have coils you can always try & adjust it to get low enough. But even if they don’t work, the car will still look beast.
At this point, I’m mainly trying to see what kinda stance I want the car to have. I see everyone saying a slammed DC5 sucks so Ig i’m gonna try & get maybe 2in off the ground? Maybe the diffusers will work better at that height.

Oh really? I’m looking into tein advance coilovers for my set up. But I doubt I will ever use the adjustments so I’m also looking at shock & strut combos. I’m not trying to cheap out but at the same time, I don’t wanna drop $800 for some features that will only be used maybe twice, since my car is a daily.

I've been thinking about getting adjustable clovers just so I can set them to the Mugen height in the winter for snow driving, and drop it another inch or so every spring. But I'm guessing you don't have that problem in FL, haha.

The problem with non-adjustable suspension is that if you don't like the comfort or height, you're stuck with it unless you want to spend the money on a different set until you get it right. You can read online reviews all day, but everyone has their own individual idea of what works for their own local roads or parking situations (roads in my area are kept damn near flawless, but go an hour south to Denver and it's potholes for days). At least with adjustable, you can keep experimenting with the settings until you find something you like, so there's that to consider.

Yeah thats a pretty good point. I wanna be as low as I possibly can, without bottoming out. Coils is probably the best bet. I’m probably gonna go for this splitter/diffuser & maybe add some canards with it. Should see a good increase in cornering speed. Tbh they just look badass lol mostly straights in Fl anyway.
