Exclamation

Before I get myself killed, or spend a lot of money just to spend more later, I need some advice. I want to vamp up my suspension this summer. So far I have the Bilstien 1516/1517's, and I would like stock Imp front springs, and rear 9C1 springs. I also plan on getting the BMR upper and lower control arms, stock length and non-adjustable. I am not an incredibly experienced driver, but would like to be able to make a corner doing more than 30mph without having to remove my face with a spatula from the drivers side window. So my problem is, what swaybars should I get to acheive a set up that isn't too neutral, tending more to understeer? I'm afraid that going from the current stock old man caprice set up to something drastically neutral will land me in the hospital or in the dirt pushing up daisies.
TIA,
Meg

You want the HO sway bars, front and rear.
VASTLY better handling, with still a little bit of understeer. (If you wanted dead neutral you'd use the HO rear and the F-body front bar).

The bars are available direct from HO Enterprises, or from Malibu Performance in California (search on "Malibu" in this forum and you should find a phone number).

you might want to check this thread for a little more info. I just ordered my rear bar from Kem at HO. I already have a f-body front. You might also want to install body bushings. Dal can help you with that

I'm running Eibach lower front and Extra HD 9C1 rear springs.

Good luck here is the thread. https://www.impalassforum.com/cgi-bin...&f=16&t=000977

Cool

just put on the bmr lower rear control arms and ho/ha rear sway bar.

some observations:

the front bolts on the control bars are a @#$)* to get off because they are inside the frame.

both the front and the rear bolts on the control arms are a #@[email protected]# to torque because of limited space

the sway bars bolts are a piece of cake

what the hell is the shop manual talking about a speed sensor being attached to the control arms? didn't see anything like that...

with the ho/ha rear bar and the stock front bar, it handles pretty decently (feels much better than before, but i usually dont push the car very hard anyway)... i thought the ride would be a lot harsher, but it actually seems like when i go over bumps now they don't jar me as much as before

the stock arms are flimsy garbage

bmr rear control arms are pretty nice quality

which way is up on the ho/ha rear bar? i put the indention near the bolts to the up side...

i'm going to put the f body front bar on tomorrow.

i think the key may be that a totally neutral setup probably isn't that dangerous unless you are really pushing your car and don't know what a neutral setup feels like. but if you are going to be driving like this, you need to slowly find your limits and always know where they are.. i hardly ever push my car at all, so i think i'm safe with the ha/ho rear and f body front...

what do you guys think?

btw, did anyone put locktite on the rear bolts when they did theirs (arms and sway bar)? the shop manualy didn't say to but it seems like someone here said they did

I think you're safe with the HA/F body swaybar setup, as long as you pay attention to what you're doing, but you now have to be much more careful about other suspension changes, like springs. See this thread: Swaybar/Spring Combos for a discussion about why. On the loctite, definitely use it. In fact, you should clean the bolts and the bolt holes first with some degreaser and then use the loctite. Those bolts will loosen up otherwise and you run the risk of losing them. Apparently, BMR uses a lot of cutting oil on the threads in the LCAs which can lead to problems down the road, as it were. I mounted my swaybar the other way up, but I don't think it makes much difference, as long as it fits flush to the LCAs and it doesn't interfere with anything as the suspension travels. One of the Mueller articles on installing this bar tells you go flat side up on the stock LCAs and indented side up on some aftermarket arms, so I'm guessing you're just fine.

threads in the lower control arms? mine didn't have any threads... just holes for the bolts to pass through.

i just realized the control arms came with instructions... it says to torque the control arms bolts to 75lbs.. i did about 100lbs like the shop manual says.. i wonder if it will make any difference..

i didn't clean the mounting surfaces or anything... and i reused all teh stock bolts and nuts (i see the bmr package had some bolts, i'm guessing for the sway bars). i didn't use any locktite either

reading the swaybar article on b-body.net, i think i must have gotten the mid-96 rear mounting hardware upgrade..

but my bolts were 15 milimeters, not 10 (or is he talking about bolt diameter)

i'm going to check to make sure the bolt was long enough (nut has enough thread to grip) but i don't remember it being too short...

We were talking about different bolts. I meant the bolts for the swaybar, not the bolts for the LCA itself. Clean the bolts and the holes for the swaybar bolts, and use loctite. Someone else on the forum lost three out of four of those for the reasons I described above. On the LCA bolts, I followed the instructions that came with the BMRs as far as torque and re-used my stock hardware. I did use loctite there, too, out of an abundance of caution. No problems so far. The stock LCA bolts and the swaybar bolts that came with the BMRs were both fine. I have a feeling that if you used the stock swaybar bolts to fasten the HA swaybar, they may be a little short. My recollection is that when I put the stock bolt through the HA swaybar, there wasn't much left over. Hope that helps.

the bmr rear lower control arms i recieved had no screw threads on them whatsoever.

the original swaybar bolts were long enough and probably strong enough as well (in mid 96 apparently they started making the bolts longer and that's what i got), but i replaced them with the bolts that bmr sent just to be safe. the threads on the bolts were bone dry, no oil. i didn't use loctite because the shop manual specifically says not to use this type of thing unless it says to, and it doesn't say to for the control arm or sway bar bolts...

bmr only sent swaybar bolts, none for the bushings, which is fine because i think the stock ones are ok. i didn't use any locktite here either, but did torque to 100lbs instead of 75lbs like the bmr instructions said... hopefully it wont make any difference

the ride quality in general with the bmrs + ho rear bar is vastly improved.
