so what if i use a mugen 32mm 3 way rear sway bar would it be better to have a slightly stiffer front since so big or no? what rates would be good for this?
Mugen does not make a 32mm rear sway bar for the DA.
sorry i meant a-spec, but i dont really understand how the rates and the sway bar works like the stiffer the spring in the rear the bigger sway bar or opposite?? just so i understand.
The sway bar makes the car resist leaning in corners, this is essentially adding spring rate to the same end that the sway bar is installed. Sway bars only work when the car is leaning. Generally, the larger diameter bar, the stiffer it is.
I’m running 450 front and 450 rear (8kg/mm) and the car is pretty neutral with the stock swaybars. It does lean in the corners, but I should be upgrading to a 19mm rear swaybar and better bushings in the front.
It gets a little stiff/uncomfortable daily driving the L.A. streets, but the performance is well worth it.
if you could change rates again what would you do next time round? just curious since youve had that setup
At the moment I’m running 450f and 400r with 22mm rear ITR bar, currently with Ohlins shocks, shortly changing to Koni.
Ride height isn’t particularly low, but I still have occasional bottoming out issues on the roads round my way with the front, and wouldn’t want to go softer. I’ve never autocrossed, but I do a lot of what you’d call circuit trackdays as often as possible.
I find this setup to be very stable, vitually no understeer at speed - even under power the car drifts wide in a very neutral way. Tha car’s tail will still easily step out wide if I lift, especially in the wet! I’m planning on improving drive through corners with a better LSD, rather than changing suspension next.
Whilst the actual rates on this setup set are front biased, you’ll find that when you take into consideration the car’s weight distribution, you’ve got an evenly balanced car. This alllows adjustability on the throttle, whereas a car set up with strong rear bias will (i.e. what you guys seem to use for autocross) always want to oversteer, not something I’d particularly want on a car which gets driven hard on the road. Due to circumstance I was driving round with a 290f 400r setup not long ago, and on fast A-road it was very scary at speed - you could feel teh rear wanting to come round in steady state corners - felt like you need to keep the throttle buried or you’d die. Not good on the road.
Id say think what use you’re going to put the car to. If you drive fast day to day, canyon roads and the like, I’d say 450f 400r was about right, depending on the quality of your roads. Get an ITR rear bar as well. Much more than 400 in the rear and your teeth willl start falling out too.
If you’re planning on lots of Autocross, then go with what’s known to be effective for that.
hth
PS - with these sort of rates, try and make sure you’re runing at least front and rear strut and tie bars, otherwise the car’s body will sart becoming part of your suspension setup 
I would probably stick with the same spring rates, but I would opt for Koni Yellow shocks instead of Tokico Illuminas.
alright so 425f/400r or 450f/400r is there a big difference? i live in florida and there are some roads that are bumpy and un taken care of and most others are fine like the main roads. i do drive fast on the road and around corners so i dont think i want to have a stiffer rear in that case.
A little OT but I’m using H&R Sports and they’ve been great for a road setup so far. I think they’re 270F 270R so they’re quite a bit tamer than most people’s in here… But for a street/sport suspension I’d say they’re good springs (I have them paired with Koni Yellow struts…).
my friend has a jetta with full koni coilover setup and its pretty stiff, anyone know what rates they are? so 425f/400r sound good?
425 or 450 front should be spot on
got this from somewhere before, to give you an idea, think H&R Race and Eibach sportlines are both 450fr for the DA iirc, despite what it says below
lots below are for DC2 and i’m not guaranteeing accuracy, but it all helps.
i’d go 450f 400r again given the chance

You can’t compare Jetta spring rates to Integra spring rates, the suspensions have different motion ratios. The Jetta is MacPherson strut up front, and some sort of torsion beam style. The Integra is unequal length control arms front, and trailing arm/unequal length in the rear.
I already told you what would work well on your car but you don’t seem to care. Get 400/400 and upgrade the rear bar if you want it to handle better.
not includeing the shocks and springs where do you get good suspension stuff for our cars?
I installed Koni Yellows/GC on my '91 GS this spring, and originally went with 380 lbs f/350 lbs r Eibachs. Couldn’t stand it, even for normal street driving (the car is a daily driver which also pulls regional autocross duty, along with the occasional divisional). I was actually getting a bit of coil bind when cornering hard.
I swapped springs last week and have 800f/500r Hypercoils now (Hypercoil dealer happens to be closer to my house). Lengths are 8" in the rear, 7" main with 4" helper springs in the front – perches are about halfway down the rear sleeves (perfect), and about 3 threads from the bottom on the front sleeves. Maybe shorter springs up front would be better? I’m on the middle circlip on the shock body all around. It still isn’t quite as stiff as I’d like. Wheel rates should be around 355f/275r. I’ve currently got some balance issues (corner exit understeer). I think I’ll need to add the compression adjustment to my Konis to get things right, since springs will get you close but not perfect. I’m not too thrilled about the $$$ and all the extra install time to get things tweaked, but it should be a great setup after the dust settles.
The 800f/500r is not bad at all on the street. Kinda cushy, actually. Just don’t hit any potholes 
If you’re not willing to deal with the hassle of trying a bunch of spring rates and tweaking the spring perches, then I’d recommend sticking to Illuminas/ProKit. Pretty good for not a lot of money, and hassle-free as far as my experience goes.
uhh…yeah, that’s due to the 800lb springs up front in comparison with the 500 in rear. Also might have to do with the fact that standard Koni Yellows can’t handle 800lb springs. Or might have something do do with coil bind up front.
I realize my setup is not optimal yet, I’m still trying stuff out. I definitely need to get the OTS Konis revalved to handle the stiffer springs (they were pretty much maxed out with the 380 lb springs), but I also feel I need more compression all around, whether that’s via stiffer springs or double adjustable Konis. The ride is definitely firm, but not harsh by a long shot. I was just supplying a data point from my experience so far with GC/Koni 
The coil binding was happening with the original 380/350 springs, and only with the front springs. That’s no longer an issue with the 800/500 springs. The rear feels stiffer than the front. Wheel rate to corner weight ratio is about 0.565 in the rear and 0.428 in the front (using approx 830 lbs front cornerweights, 486 lb rear cornerweights). I need to get around to actually putting the car on scales too.
There aren’t many autocrossing G2 Integras here in central Indiana, so any advice on good G2 autox setups is welcome
chsscott, did you need to install backing plates for the Progress rear sway? It looks like they make both 22mm and 24mm bars. I’m running a ST rear now which worked well with the Illuminas/Prokit, but wondering if I need to go stiffer for the new springs. Not being able to rotate the car is not fun…
