I want to increase my 2019 Si's handling, but not interested in engine mods at this point so I bought an Eibach front and rear sway bar kit plus a Siri Moto strut bar. I ordered the suspension upgrade from Honda.

From research I have done it would seem I don't need both sway bars; the rear sway bar on its softest setting is suggested for the street. Bottom line... should I install both front and rear bars or just the rear bar? I want better handling on the street, and do not plan to do any track stuff.

The rear sway bar is a huge improvement. I have the Whiteline, but it’s the same size as the Eibach. The front one will make a difference but not as much. Also, you have to drop the subframe to install it. I don’t plan kn doing the front, but it’s obviously up to you. When you install the rear, make sure you use either the Eibach adjustable end links or the OEM Accord end links.

Installing a front sway bar is a pain, just forget it, and also the Si already has a 27mm front sway bar so I think that's thick enough. Rear sway bar upgrade is great. Actually, if its just purely for street, the sport mode already does a great job adjusting the shocks dampers but if you want, buy all the braces that you can if you really want to improve your handling by miles.

I'm gonna take your advice and install only the rear bar. Thanks for your cogent reply.

Somehow I doubt the veracity of your reply, but thank you for your time and patience.

You should probably install a front tower bracket, you can buy a good quality one for inexpensive and they are easy to install. They will stabilize the front suspension in turns. They are great for autocross, but since you are only doing street driving you are not spending a lot of money and making the driving experience better

Why do you suggest using different endlinks? I'm currently running the Eibach rear bar with the OEM Si endlinks on the stiffest settings. Been using it for about 10 months with no issues.

It’s what was suggested to me, since the sway bar is bigger and generates more force on the end link. The stock Si ones are plastic and the Accord and aftermarket ones are made of metal.

To improve handling: rear sway bar, front strut bar, lowering springs, better tires, lighter wheels.

What do you mean by "improve handling"?

Reduce understeer?
Reduce body roll?
Improve ride quality over bad surfaces?
Overall skidpad grip?

Since tires are the only item on the car that touches the pavement, it would be logical to start there imho. Then perform changes that address the issues you wish to change. Sometimes, the car is very good at its basis and its the driver who makes changes for the sake of change. While some mods feel better, unless you have some type of data to back it up, you never really know. Creating a car that might pull 1g in cornering could result in a car that is unbearable to drive anywhere but on an ultra smooth surface. Going to a thicker rear sway bar may be great on the track or AX, but if overlooked, could cause the car to be more skittish on washboard pavement curves.

That said, the usual culprits would be
1) Tires (and lighter rims)
2) Sway bar(s)
3) Springs
4) Shocks
5) Alignment
6) Reducing weight

If it were me I'd stick with the rear ARB on the lightest setting, and throw the funds from the front ARB/strut bar into a decent set of Pilot Sports.

For a FWD car, this chassis exhibits surprisingly little understeer up to 8/10. :cool:

All will be installed by Wed. except for the lowering springs. If I were a serious track day junkie I'd go for that, but JMHO, on the street I see them and an opportunity to ground something.

What’s the part number for the whiteline? I tried searching their website but it’s not the best. As a side note can anyone find the rear only eibach kit? Even the Eibach website appears to be out of stock. TIA.
