Need some help guys. I have a 89 DX and HF rex. I'm selling the HF to fund the DX. I'm looking for help on the sway bars. I know the HF has a front while the DX does not. Should I put the HF's bar on the DX and buy a rear for the DX. Or should I buy new f/r bars for the DX. The rex is getting new Ground Controls with AGX's in a couple weeks, the rear disc swap and new pads around.

What is the stock size of the HF's bar and what size should I consider for the rear.

Thanks in advance.

The dx does have a front bar, and it's a little bit bigger than the HF front sway bar. Neither have a rear bar. Don't 'upgrade' your front sway bar unless you're changing to an HF sway. You should definitely buy a large rear bar, Suspension Techniques, Eibach, and Neuspeed all make nice kits.

They both have front sways, and neither has a rear. The HF front bar is smaller, and generally thought to me more desirable, coupled with a rear bar it will have less tendency to understeer. I would keep the HF bar on whatever you're driving. Why selling the HF? It's a lighter chassis to build on.

For the rear sway install, you don't have everything you need. Here's a write up on how to get a rear bar in there. You can use a normal Si bar or buy an aftermarket one, if you're planning to autocross you probably want aftermarket.

Even with the integra rear brake swap? I thought that would solve the install problem for the rear? The parts are off a 93 teg.

Well, you do need the LCAs with threaded holes for the sway bar... but the car doesn't have nuts welded into the frame for the bracket bolts (it's in the write up). The teg LCAs might be a little long, I'm not sure, I know you can use them but you might have camber issues.

The HF is going since it has a considerable amount of rust on it. The DX is cleaner. I'm not going to be auto-xing or racing anytime soon. Just a daily driver with a little sport feel to it. Not to worried about weight.

i think only Civic CX and STD don't have front bar!

So, are the DX and HF sway bars the same? Or should I swap the DX with the HF's?

DX and Si front swaybars are the same. 18mm.

HF bar is unique and smaller. 17.2mm and hollow.

those who like to tune their suspension for competition prefer the HF bar because its not desirable to have a stiff front swaybar.

but consider the whole suspension package, an HF bar alone is not going to be of any benefit.

The DX and Si bars aren't the same, the Si is 19mm, so is a bit stiffer.

If you're not looking for something extreme, I'd try and put on a stock Si rear bar along with a DX or HF front bar. That should give you some rotation but nothing that is really going to get you into trouble. For my setup, a DD with autocross use, I'd have to say the Suspension Techniques rear sway bar was best suspension mod I ever made. It all depends on how much rotation you're looking for.

Agreed with above. If you're not planning on racing anytime soon and just want a good, sporty DD...get an Si rear sway bar. They can be had for cheap and will give you what you're looking for. If you do decide to get into racing it though, the Suspension Techniques rear bar is where it's at.

p.s. I've probably got a rear si sway bar if you're looking for one.

no, really its not different.

check parts numbers yourself. ive gone out and measured them as well. you can also look at the stamping on the rubber bushing identifying the diameter of the bar. it should have an "H". its the same on DX and Si.

the 19mm is from a 4dr sedan. its a "F" bar.

HF is G.

DA is K.

I stand corrected. I had always remembered the Si as having a larger front bar, but I was obviously mistaken on that one.
