right now I'm using ground controls (not sure what the spring rate is) with AGX's and I'm not really happy with the way the car rides, feels like it fly's off the ground when I go over a bump on the highway.

ANyway I've been doing some research and I think I need to get some progressive rate springs, but I'm not sure which ones. I hear a lot about H&R sport springs, what else is out there that's good that gives about the same drop?

 

Neuspeed, both the Sports and Race springs, are progressive. I have the Sports on my Prelude and absolutely love them.

Thats because your shocks are underdampening.

Get a quality shock like koni reds/yellows and you won't have this problem.

 

his shocks are adjustbale i have them also on my car and mines work fine did u try making them stiffer?

 

I really think it's the linear type springs that's causing my problem...

 

Well, the floaty feeling on the highway is def. from underdamping. Get some stiffer shocks, or adjust yours stiffer.

I doubt that.

I had H&R Sports and they delivered a decent ride paired with Tokico HPs. If you are underdamped, the ride will feel rough. I don't know what "it feels like it's going to fly off the road" means so I can't help any further. Try driving slower.

its not. If your shocks were stiff enough you wouldn't feel like you are about to take off on bumps, the shocks would control the springs enough to prevent that feeling.

AGX are adjustable, but even at the stiffest setting they are not valved to handle most spring rates.

 

I think I know what you guys are saying and that's not my problem, I should have said dips in the road and not bumps. I'm still pretty sure it's the springs. With my AGX's on 4 it's even harsher so I doubt it's the shocks.

It's like this.....I'll go over a dip in the road at like 70 and you can feel the tires losing contact with the road because the springs are so damn stiff that rather than work with the road the work against it.

my dad has a mazda protege 5 and that thing rides REALLY nice. I'll get in his car after driving mine for a while and I'll be like, damn, this is what I want my car to feel like. You can still feel every bump in the road, but I don't get that "out of control" feeling that I get in my car when I go over a dip in the road.

 

keep your struts and get H&R Sports or Race if you dont live in a snowy state like me

Consider this,
doe you car feels like it's "skipping" over the bumps, or does the traction is lost during the rebound of the shock absorber. if the latter, then the dampers are too soft on the rebound setting.
my car sometimes skips over bumps during cornering, due to the high spring rate, stiff antisway bar and shitty tyres. the fronts are a little under damped, hitting a dip especially over high speeds sends the front flying up. a higher setting up front will solve that problem.

well if you want your car to ride super smooth then put some stock crap back on
and give me your agx's
i will trade you a set of stock eg suspension and some misc. parts for them

well I may have a set of ground controls for sale

 

the car feeling floaty after a dip in the road is due to inadequate rebound from the SHOCKS.

The shocks control the compression and rebounding of the springs. With out shocks, once you hit a bump you would keep bouncing until all the kenetic energy was used up.

If the feeling happened when you first entered the dip, it would be because of too high spring rates. Since its when you are coming out of the dip that you feel it, its the shocks inability to control the rebounding spring.

You can buy different springs, but its going to have the same problem.

why do you say that? is the drop really low??

What's happening to me is the exact opposite. I don't get ANY floaty feeling at all. The problem is that the springs are so stiff that the car will feel like it's actually lifting off the road when I go over a dip.

I think a lot of it has to do with there being so little "travel" that the linear type spring gives you. whereas the progressive type would give you more travel.

 

Tavel is uneffected by spring rates. All a progressive spring is, is a spring that has lower rate coils that are compressed before the heavy coils.

What you are describing is underdampening to a tee.

I have driven 500ft/lb non-progressive springs on some of the worst road in michigan and never had a problem feeling like the car is lifting off the road. Because the shocks used had enough rebound to control the motion of the spring.

Do you have the "limited edition" ground controls, or the standard?

 

well I'm by no means an expert but it seems obvious to me that a higher spring will not compress as much as a lower spring rate and there for not travel as far.

 

Yes, travel per the same weight transfer is effected, but maximum allowable travel is uneffected by spring rate.

Which ground controls do you have?

 

If the wheel is not entering droop fast enough and is lifting off the ground, you could be overdamped. Rebound damping controls the speed at which the spring unloads (releases KE). Too much rebound damping and you'll see "jacking down" where the suspension does not extend fast enough and bottoms on a following bump. I think this makes more sense if the car is stiff coming off a bump. If the car is underdamped then the "floaty" felling is from the spring unloading fast and pushing the car off the ground.

However, AGXs are rebound and bump adjustable, correct? Not enough compression damping will allow faster spring compression and a rougher ride. Most likely you are underdamped. Adjust stiffer or find softer springs.

EXACTLY....i have the same problem. The car is not at all "floaty" after the dip. Once it gets contact again it is a solid as needed. Its just that the dip almost acts like a ramp and the shocks arent unloading fast enough to maintain contact.

I try not to drive fast over areas I know that do this....I have GC's and AGX's also

Hold on. Your contradicting yourself. You describe his problem to a T and say hes overdampened.

THEN you say hes probably underdampened???

 

OK. here are my spring rates: 200.64.67 in the front and 180.64.44 in the back.

Sounds pretty soft to me. Either way, I think I'm gonna sell them, they squeek like banchees, the ride sux, and I can't even adjust them anymore because there is so much grit in the threads.

I hear spoons are nice

I don't think I actually described his problem to a T. I described the "jacking down" probalem to a T, but I don't think that's what he's experiencing a.) because AGXs don't really offer enough rebound damping to worry about that (requires lots of rebound and little bump); b.) he claims it feels stiff during the dip (bottoming suspension); c.) because I really don't think he knows what is happening either.

I described 2 separate situations both of which could be his problem yet with different causes.

Are these 200lb/in and 180lb/in? If so, your springs are too soft and you are bottoming your suspension which is why is feels rough, and you should get stiffer springs, or raise the ride height.

 

Do you have the limited edition ground control coil overs? How many times do I need to ask

The limited edition ground controls ARE progressive rate.
