How did you guys remove the endlink with the nut. You know the one that has the 4 purple does on the bolt side. I put a wrench on the nut side, and the whole bolt moves with it, so I can't get it off without putting something on purple dotted side, but I don't know what to put on there so I can get the nut off. Help anyone?

[truflip]

you stick an Allen key in the endlink, hold it and use wrench.
black07coupe, sorry I dont have the part number.

This mod made such a huge difference to my Civic. The only problem now is I always drive faster around corners. Thanks again!

a little info for those who don't think their sway bar upgrade helped, or for those interested in what a sway bar does:

The first is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width.

The other function of anti roll bars is to tune the high g / limit understeer behavior of the vehicle. The limit understeer behavior is tuned by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing the proportion of roll stiffness at the front will increase the proportion of the total weight transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a higher slip angle, and the outer rear wheel to run at a lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer.

Because an anti-roll bar connects wheels on the opposite sides of the vehicle together, the bar will transmit the force of one-wheel bumps to the opposite wheel. On rough or broken pavement, anti-roll bars can produce jarring, side-to-side body motions (a "waddling" sensation), which increase in severity with the diameter and stiffness of the sway bars. Excessive roll stiffness, typically achieved by configuring an anti-roll bar too aggressively, will cause the inside wheels to lift off the ground during very hard cornering. This, of course, is only possible if the regular spring rate actually allows the outside wheels to handle the much increased load. This can be used to advantage, in fact many front wheel drive production cars will lift a wheel when cornering hard, in order to overload the other wheel on the axle, so limiting understeer.

Is it normal to hear poping sound immediately after the install? I installed mine and went on a 100+ miles trip. It was poping at the very beginning of my trip, but none at the end.

[truflip]

Hmm.. mine never popped. It's an EX though. But if it's gone now, get under and check to make sure all the bolts and tight and it should be ok then.

Just in case anyone is curios you can swap out the front and rear sway bars with out jacking up the car. (Stock suspension height civic dx-g) That is how I did mine. I had no problems. Just Make sure that the car is on level ground to prevent tension on the sway bars.

Just some clearification for those interested in upgrading their LX/EX rear sway bar to the Si sway bar... you need more parts than people are stating on this thread. You will need both the L brackets that the bushings and D shaped brackets connect to. The Si D shaped brackets are bigger, therefore the L bracket needs to be changed. Also, you CANNOT reuse the bolts from your LX/EX sway like everyone is saying... you need to get 3/8 x 1" bolts... course thread. I did mine yesterday and had to drive to home depot to get these bolts without any sway bar on... my car was bouncing every time i took a turn hard (boston roads...). But ya, the upgrade was worth it. The car feels nice and planted now, and quick jerks to the left or right feel like nothing.

To anyone who has been contemplating getting the Si sway bars for their non-Si: Don't hesitate, stop debating, it was the best $149.18 after tax I've spent so far. The front sway bar on my EX felt like it weighed nothing compared to the Si sway. When I first looked at the stock sway while it was still on the car I thought, wow it looks like it's the same one I just bought. It is NOT, not only is it heavier it is also slightly lager in diameter. The rear is even more noticeably larger. The parts listed by the OP are exactly what you will need for an EX. I was excited when I started to hit a few corners out on some back country roads, and thought I was going to fast, but with the beefier sways it feels like your not going that fast at all once you enter the corner. Next on the list, HFP suspension.

+ rep for the OP

It's probably already been said but getting Si sways isn't worth it.

If you have a *x line civic I would just get the progress rear sway bar.

Almost the same price as two bars from an Si. But the Si front sway bar is actually thicker than ours, which is exactly opposite of what you want. It might things a bit stiffer up front, but will increase understeer, which is the point of increasing diameter of the rear sway.

I don't know how big the stock Si rear sway bar is but I know the progress is 22mm which has a few mm on the Si.

So spend $150 or so and just get the rear sway from progress.

I made the decision to just go with the Si sways so I didn't run into the problem of having the end link pull thru the mount. I know weld washers on it. While my brother-in-law is a welder by trade, it's not always convenient to find time we are both free. If I find I want to upgrade again and want to have the bracket beefed up for the progress bar I'm sure you'll see my Si rear sway for sale. Till them I'm pretty happy with the Si bars. Plus you can't really go wrong for $40 for the Si rear sway.

[mO 64 StAnG 06]

If it's just $40 and you have an LX/EX then thats one hell of a deal.

I think the people that are running into the problem of ripping out the subframe or breaking endlinks are pushing the car a lot harder then us that see nothing but city streets.

These guy's must be AutoXer's, I havent had a problem yet and I take turns a bit hard and fast.

I'm just currious do the bushings and bushing holders have to be replaced when the front sway bar is replaced with the SI sway bar?

Also, can I assume the Acura CSX has the same front bar?

p.s. I've already done the rear SI sway bar on the CSX

How hard is this install?

fairly easy if you have the proper tools. i did it in my driveway in about half an hour. jus make sure ou have all the parts before yiu get started.

What tools do I need

You can't be serious.... Go search for a DIY.
