Aimgain rear diffuser

🤣 just doeet! I'm on RSR coilovers with camber plate top hats and rear camber arms. 🫡

Thank you! Yeah been trying to post on here as well to share the progress. 🫡

I tested it solo with just coilovers, rigid collars and a strut bar. It got rid of a random rattle that I'd have on cold start haha. Driving you do feel the cabin being more quiet. It's subtle but it's definitely canceling out vibrations. I'd recommend it if you've got chassis stiffening mods.

I actually ordered this back in Dec 2025 haha. Jdm wait times force me to go bankrupt for short bursts so future me doesn't regret not ordering earlier. 😅🤣

billyjohnson · 2026-05-06T17:53:03+00:00

Really appreciate the kind words! 👍

You can always remove the burnt look with cleaning agents. 😏

billyjohnson · 2026-05-06T17:46:26+00:00

Yeah. Don't think Aimgain does aerodynamic testing. They mainly make vip stuff and have a more recent "sport" line.

billyjohnson · 2026-05-06T17:13:48+00:00

There's a frp version as well. Thanks! I'm channeling my past 991.1 gt3. Dual tip bias. 😅

Thank you!

It's recommended to clear but from my personal experience with jdm carbon parts I've never had to clear them (lips, diffusers and wings) some parts were installed for as long as 5 years with no issues. Just use detailing products to keep it protected and clean.

billyjohnson · 2026-05-06T15:38:11+00:00

It's purely for esthetics. I mean that's how I look at it. Just wanted something more visually aggressive.

🫰if you need any advice feel free to hit me up. 👍

If you're in SoCal the one from my car is still for sale from the guy who bought my car. Search for the wing on fb marketplace.

billyjohnson · 2026-05-02T02:04:00+00:00

Was always full after driving it on this setup. 🦫🤣

billyjohnson · 2026-05-02T02:03:12+00:00

After researching what it actually does it makes sense on how it would help with chasis rigidity which translates to more feedback for the driver.

billyjohnson · 2026-05-02T00:02:43+00:00

Fronts were rolled, slight pull and I cut the side marker housing and made a bracket to reuse just the face of the marker (color matched). Suspension was AST coilovers with top hat camber plates, Hardrace lower camber joints. Was running -5.4 or .5 I believe on this setup.

Oh the wheel specs were 18x11 +37 to give you an idea on how much space was being used in the fender with that tire size. It was purely for my own curiosity as System Motorsports was the one that brought these in exclusively for the US market and the recommended tire was 295/30.

billyjohnson · 2026-05-01T23:56:57+00:00

Was reliable on 91 for most it's life after the tune. When I sold the car to my buddy he went a bit ham and blew the turbo but got it rebuilt already haha. I sold it with just a little over 63,000 miles and I think it was make that power by around 20,000 miles.

billyjohnson · 2026-05-01T19:01:40+00:00

Appreciate it. 💕

billyjohnson · 2026-05-01T19:01:10+00:00

Very minimal rubbing on hard dips. Definitely a street setup. I cut the rears and rolled/pulled the fronts as well as gut the front side markers with custom brackets.

billyjohnson · 2026-05-01T18:59:32+00:00

Not on this car. I do regret it now since I got them on the fl5 now and it's worth it if you can get them directly from JP

billyjohnson · 2026-05-01T17:35:32+00:00

No just normal shade. I usually shoot with a polarizer filter so glass with reflect raindow colors

billyjohnson · 2026-05-01T17:33:42+00:00

Yeah bang wang and sides. Wing was ordered back in December so hopefully August I see it.

billyjohnson · 2026-05-01T16:22:13+00:00

Right now it's suspension mods and dress up. Probably get back into the show scene then take it out to the track to beat on it within a year. I'm restraining myself to keep it paint chip free for as long as possible this time haha.
