i have plans on purchasing the progress 27mm front sway bar for my '04 civic (replacing stock 15.9mm front sway). my 2005 RSX-S rear bar (21mm) is on its way in the mail, so im hoping the front sway i get from progress will be enough to balance the car out with the 21mm in the rear.

my suspension otherwise is stock (stock height, shocks, springs). i realize that the 01-02 front bar stock is 25.4mm (i think) and the progress is 27mm, but the OEM is tubular while the Progress is solid. im not going to be racing my civic, but i just want to eliminate as much body roll as possible without having to drop the car or get stiffer shocks/springs. i was going to go progress 27mm front, RSX-S 21mm rear, but im worred about excessive understeer with the really stiff front end. maybe i should opt for the OEM 25.4mm tubular front? how big of a difference is it from the OEM tubular to the progress solid front?

please keep in mind, i want to eliminate body roll without spring/shock mods. only concern i have: excessive understeer. slight understeer is fine with me (just street driving, occasional spirited cornering). ideas? im for sure going to swap the front with something thicker/stiffer (swaybar), just need opininons.

ohyes, almost forgot, im on a budget as well

and one more quesiton: are the RSX-S front sways interchangeable with the EX front sways, as with the rears?

thanks!

not with the ex fronts, there is a huge diffrence you will feel right away... the ex front is diffrent due to the cat on a ex...

wait... what?

what is not compatible with the EX fronts? RSX front sways?

yeah the rsx front sway bars wont fit a ex. it will only fit a lx and below. Go with the progressive or just buy a front sway bar off a 01-02 member. Its way cheaper then the progressive. I got mine off of hondaluver for $40 shipped. I'm going to install it when my camber kit gets here.

if you have to much understeer you could switch to the 21mm rear.........

get the 27mm hotchkis rear for the rsx

Eh... I'm not a fan of big front anti-roll bars on FWD cars, it causes more performance issues then just increased understeer. But, you probably would never notice if this is just a street car. If you were setting the car up for track use...you absolutly would not want a larger front anti-roll bar. With that being said, you've pretty much decided to tune totally with anti-roll bars... Interesting.

Some suggestions;

Normally I'd tell you that you shouldnt be paying much attention to how much body roll the car does or does not have, as its a Very poor indicaton of how the car is handling. Anyway, since you are keeping the stock suspension (Mostly) a larger front bar may help reduce some of your understeer (Rather then increasing it) by keeping the contact pach of the tires Flatter durring corneing. I would not go too big though (25.4mm Max personaly) You may want to look at the Sedans Front bar, some years had a 22mm. Also, If you ever decide to alter the springs/shocks... One of the 1st things I'd do would be to go back to your stock 15mm front bar.

yeah thanks for that, i was actually waiting for your post on my topic haha.

yeah i JUST found out about the 22mm sedan front bar. yeah, i realize that my "tuning" of mysuspension isnt ideal, but again, its just for street use with occasional spirited driving. having less body roll, to me, i feel more confident even with chances of increased understeer with a larger front bar.

i know that the front 27mm progress bar will make the front end REALLY stiff in terms of less bodyroll. how comparable is that to the 22mm hollow bar on the sedan front (year-specific) in terms of decreased body roll? i dont wanna be at too small of a front bar and have to upgrade again to a larger front. also, i read that some users with the 27mm front progress bar felt the rear to be stiffer as well, haivng not touched the rear bar. with the 21mm RSX-S bar in the rear, it will in turn make the front end more stable as well? with people who upgraded JUST the rear on stock shocks/springs, what did you experience in terms of the front end rolling?

sedan/coupe bars the same right?

If you want to get the progress sway bar then get both the front and rear at the same time. The 21mm RSX bar isn't big enough to counter the 27mm bar up front and the car will be a pig and understeer. As a rule of thumb on 7th gens(or any strut type front suspensions): Run as thick a front bar as you can without having traction issues or skipping, then tune the thickness of the rear bar accordingly.

Why it works: With the lame strut type suspension we have we lose alot more camber as the car rolls vs a double A-arm meaning that our contact patch decreases faster as the car rolls than the older civics. this is an issue, especially when our rear suspension is actually quite proficient at maintaining proper camber. giving us nasty understeer.

So we get a bigger front bar, enough to keep suspension travel limited and the contact patches stable, this is good except the roll couple of the car is messed up if we only do the front! Also we need to be careful not to go so stiff that we lose alot of traction off the corners because these cars are slow enough when the tires are gripping.So we go get a fat rear bar and some big rear spring rates, we're basically just dragging that end of the car around anyways so we want it to rotate by lifting the inside tire and reducing rear traction. The bigger the rear bar, the better it turns in.

I autocrossed with the progress bars front and rear in STS in San Diego, I actually raced with zzyzx a little over a year ago I think. If you do both progress bars, also shell out for some more agressive spring rates and dampers because the stock bits get pretty overwhelmed. Also a good comprimise is the stock front bar and the rsx rear if you plan on just streeting it, it's waaay cheaper.

I just put on my RSX type S 21 mm sway in back. I just have the EX 01 OEM sway in front. I have a front up strut bar, rear up strut bar, and a meagan racing tie bar. I am very happy with my set up so far. The only thing is I have the stock endlinks and they look like they are bending funny. I think I am gonna have to get Greys endlinks soon. As far as upgrading the front sway, I can feel the front roll more than the back in hard corners. am tempted to upgrade to the progress front in the future.

I was thinking ab getting a Progress technology 27mm front sway bar and a neuspeed 22 mm rear sway bar. what do you think. Or should i just go stock front and neuspeed rear.

omg..so true. I think the EX bar is hollow lol. My Progress feels like an olympic weight lifting bar compared to the OEM

if i change rear and front will i get alot of understeer.

 
Rep Power: 380

Depends... are you driving the car hard enough to notice?

Seriously, for street use its fine to get a larger front bar... if you are trying to get every last bit of handling performance for track use... then you shouldn't get a larger front bar. Smaller maybe but definitly not bigger.

what exactally is understeer.

i just ordered a 27mm progress front and 22mm neuspeed rear sway bar's, hoipe i notice some difference in the handling. I hope i don't get to much over steer or under steer.

Got my front and rear sway bar's on had a few problems with rear controll arm bolt's, ended up grinding a taper on the supplied bolt then no problem's. Then i procided to install the front sway bar, put car on jack stands removed rims removed factory sway bar removed exhaust behind cat converter. Put progress sway bar in place would not go into right pitision so i removed downpipe from exhaust manifold installed sway bar no problem. Went to install down pipe back on to manifold using factory bolts, broke one bolt off in the thred's, so i drilled it out and other hole installed new bolt's. Reinstalled front lower x brace front holes lined up great but rear holed did not, so i had to grind one corner off of the spacer that goes inbetween chassy and busshing bracket finished installing x brace, test drove car i was amased how much better the car handles 10,000 time better than factory. Just wanna let everone out the know that if you're using the front progress sway bar with the neuspeed you're gonna have to modify spacer bracket to let the x brace bolt up. Also make it easy on you're self remove down pipe it will make instulation alot easier.

i just got my progress front on tonight.....at first i thought it was on there good, i took it for a drive, and the right side kept making a clicking noise over every bump. so i came back home to check it out, it started raining, so i talked to boilermaker1 on aim, and he told me to tighten the endlink better. i did, its awesome now. better than having no sways, like my car came stock (its a vp).

good thing you got it fixed befor something major happened, the profromance for the progress sway bar is increadable, you might think ab getting the neuspeed rear sway bar and the neuspeed front lower x bar.

yeah, i have no stock rear sway, som im waiting on the progress rear hardware kit...probably gonna go with an rsx-s bar of some sort. its cheaper

Do VPs come with large front sway bars? My old dx came with a large front sway bar, but no rear bar

in the past few day's i have been getting this banging noise comming from the front drivers side wheel, I know it's the sway bar pretty sure it's loose, I tightened it up once is their any one out their that had this problem andhow did you solve it. Also is their any company out their that is making new aftermarket end links for our car's

 
Rep Power: 330

just tighten the endlinks, stick a 5mm allen wrench into the endlink bolt, and then tighten the nut with a wrench. it works. i had the same problem.

i got it fixed. But i would like to get new end link's where can i get them ?

if the endlink isn't damaged i dont know why you would want a new one but you could buy these..
