So while on a little road trip this weekend i decided to open up and stretch out the ILX's legs... found that at about
115-120 you start losing stability. i very much doubt the OEM lip would help this, and in reality we really shouldnt be going that fast. But has anyone looked into any spiltters?

No way.

Car is too new, owners aren't involved enough, and not many companies make universal diffusers, let alone anything for the ilx.

And incase you had any question, you are correct, the front lip does nothing for down force and if its the front you feel getting squirrely than a spoiler would make it worse.

Id be willing to bet the only diffuser Ill ever see will be the one on the endurance ilx.

The ILX has a soft suspension and primarily VERY small sway bars. I'd recommend looking into the Eibach Anti-Roll Kit made for the 2012+ Civic as it fits our car without any fabrication, DIRECT bolt-on.

Upgrading the sway bars will make the ride more stable in turns as well as in a straight. It's recognized as the biggest bang for the buck in changing your cars handling characteristics next to good tires!

I don't see the OEM lip kit doing anything for you.. better tires and suspension upgrades should do the trick!

Hope that helps you out.

If you're asking how to get better stability in general then thats a different question entirely.

Were you feeling squirrely in the straights, turns, or both?

Since you mentioned going 115mph I assumed you were going straight. In that case you need to create downforce or achieve a lower center of gravity. A wider stance would also help. To create more downforce you need a diffuser like you asked about. A diffuser can go many places, front lip, spoiler, top of your rear window, under the rear bumper, etc. Diffusers just create a low and high air flow channel around your car like an airplane wing.
You can get a lower center of gravity by lowering the car.
Finally, you could widen your stance by A. picking up some extended wheel studs, B. getting some wider wheels, and C. a lower offset. Any of the three or all combined will get you a wider stance increasing your stability.

If it's turning then like trentimus said, sway bar will help you out. Are you understeering or oversteering? Knowing that will tell you which sway bar you want to upgrade first and how thick you want to go. Replacing your stock bushing with newer better designed bushing will help out a lot as well. Lastly, you can lower your center of gravity which will be your best idea because if your center of gravity was low enough you wouldnt even need sway bars.


Just keep in mind sway bars will only really help in cornering. When you take a right turn the body of your car tends to sway to the outside of the turn.A sway bar ties one end of your car to the other. The more your car starts to sway, or roll, the more the sway bar pulls on the other end. When going straight, the sway bar doesnt do much. Chassis bracing will basically do the same while in a straight line as well as create more rigidity to the structure of your vehicle. Increasing the front sway bar will plant the front and let the rear sway more. This will allow your back end to fish tale slightly more when turning at high speed. Increasing your rear sway will keep the rear end tight behind you, but too much will start to affect the way your front reacts to a turn.
ALSO KEEP IN MIND SUBFRAME TEAR OUT.
As I mentioned, sway bars pull on one end of your car. The harder you turn, the harder it pulls. Sway bars attach to the subframe with two bolts. Cars have a tendency to rip out the sway bar if its not properly braced to the subframe by a... well, subframe brace. Long story short, the car body rolls like a fishing pole bends. A beefy sway bar is like a stiff pole and the bigger the fish the faster the turn. That stiff rod works great for small fish, but when a big fish catches the line itll probably break the line before the pole bends.

This is a link to a good price with free shipping from a reliable vendor.

CorSport: Honda - 2012+ Honda Civic Si - 4087.320


This is one of the many ways to add to the overall stability of your vehicle. Sway bars are typically thought of for turning but they also increase overall rigidness of the vehicle which will help you maintain more confidence in straight lines.

Like ilxluv said as well.. for value after sway bars some springs would be a nice value. Springs would help you lower your center of gravity and give you a stiffer ride. One HUGE plus to the springs is that they give you a lower stance which LOOKs good. ;)
*Springs designed for the 2012+ Civic will also work here.

Hope this helps!

Sway bars would make a differnce for body roll and not a bad modification for the price. Another thing to look at for the ILX is either lowering spring kits with stiffer spring rates or a full coilover kit if your willing to spend the money.

To the OP just remember one thing if your making these changes your going to change the overall feel for the ILX. The comfort will be compromized. Is that a concern to you?
