5th Generation Preludes only.

Im considering purchaseing a set of Ground Control (sleeve over kit) for my 5th Gen Prelude seeing as they are very popular here.

please respond to this thread with:


what spring rates you picked front/back?

why you picked the spring rates you picked?

what shocks your using with them?

what is typical rates for comfort?

what is typical rates for superior handling?

and what is THE BEST rate for both?

also addressing a good ratio for the rear springs being stiffer then the front to counter understeer as much as possible whether soft, medium, or stiff setup all toghether?

 

its impossible for noone to have a 5th gen lude with ground controls on it lol,, cmon guys whats your spring rates?

 

I assume that a lot of people on here just use the off the shelf springs rates. Off the shelf rates are going to be your "typical" rates for comfort and handling.

A lot of your questions depend on how you'll be using your car. It's also good to know what kind of shocks these will be used with.

You will find some good information in the suspension forum.

I picked 440 rates in the front and 380 in the rear.

I picked those rates because GC sent me the wrong ones I decided to keep the 380's for the rear and get the other two replaced with the 440's for the front.

I'm using the Koni Yellow shocks as they are some of the best shocks on the market and have great warranty. They are also a great combo with the GC springs.

Don't really know the best rates for the most comfortable ride but I believe what I got was the middle of the road as far as a comfortable ride with a decent amount of stiffness for autox.

Your other questions I cannot answer as that is more of a personal thing. I don't have the suspension installed yet but when they are I can let you know how comfy/stiff the ride is.

 

GC and Konis work very well together. But the GC springs are linear instead of progressive, so there is a comfort compromise no matter the spring rate. You will also lose ride quality going with stiffer springs in the rear.

That said, I'm running the GC/Koni combo with 450f/500r with the ots valving and love it. It's definitely harsh on rough roads, but that's the compromise I was willing to make for superior handling.

Why? The 4th and 5th gen (non SH) share the same spring and shocks from koni and GC.

 

hmm so maybe 350 front, 400 rear would be nice and smooth for L.A street driving?

i mentioned only 5th generation becuase i wanted to see exactly what 5th gen drivers experienced, even if the 4th gen and 5th gen suspension is exactly the same, i wasnt sure if the weight or gemometry of the car was identical to get the same effects.

Also, i dont see anywhere mentioning about bilstien sport shocks being compatible with the 5th gen preludes? if this is true im screwed! lol. Does anyone have any clue about the bilsteins working with the Ground Controls?

 

I would suggest getting stiffer springs in the front as it is a lot heavier than the rear. Higher rates in the rear will cause oversteer so if that's what you're looking for then go for it. I was going to do the same until I was talked out of it for multiple reasons. One reason is that I will be driving my Prelude in the winter with the suspension. With a stiffer rear, it can cause the back end to kick out when hard on the brakes in the snow which is what I don't want

Something to look into maybe.

 

Well if you want to know what I have on my 4th gen it is 380F/440R and the only thing I would want to change is more rear spring. I wouldn't mind if it rotated a little more. Unfortunately OTS koni's aren't rated for much more than 500lbs and I don't want to change to revalved koni's.

Mine is very comfortable for daily driving. I also autocross it. If you don't race then I wouldn't be as concerned about having a higher rear spring rate. I run the koni's at full stiff in the rear for events, and 1/2 on the street. I leave the fronts at 1/2 all the time.

As far as the bilstein question you have to specify when you order your GCs. There is a special collar that goes with the GCs for konis. Most other brands fit without the collar. I believe GC explains this on their webpage if you want to check it out.


my 2 cents

 

eheh, I have those spring rates but I'm putting them on the opposite way. 440F and 380R. They are both 2.5" and 8" tall so I can swap them if it doesn't work out the way I want.

Have you swapped your springs before? Any reason why you like it stiffer in the rear compared to the front?

 

I am running 400fr/380r and with the Konis on stiff its back breaking. When on soft its still not great and you will feel every crack in the road. All this and I use 225/50/15 tires. I personally think if youre not going to see a Race Track the GC/Koni combo is overkill. I have the Eibach/Koni combo on my other Prelude and its ideal. Fun for the street and fairly agressive on the track.

 

'Can97SH' the reason i want stiffer in the back is to counter the understeer enough to 4 wheel drift in a sence, i just dont want to understeer, i want it to be as even as possible when loosing traction. Thats why im so persistant on wanted a good ratio where the back is stiffer. (also i ussualy never drive in rain or snow, im in southern California, its sunny almost all year round lol)


'95preludesi' thats sounds like a good setup dude, how comfortable is it for potholes, and rough roads, or irregular roads? does it handle is well? also, is your understeer completly countered? do you oversteer now? (and not by jerking the wheel, even by easing into a turn speeding up, how does the car react?)


'NirVtec' the only reason why i want the ground controls is becuase i need desperatley need the height adjustablity, if not i wouldnt change my H&R Race/Bilstein Sport combo even if i was at gunpoint

 

bump

 

im on 560f/450r (tein flex....not GC)
pretty rough on the streets
but works well for autox
no track here to test them

 

Have you considered a Rear Sway Bar??? I forgot what Understeer was after I installed mine. Now I battle oversteer problems with tire pressure which I have no problem with. My car also sees alot of track use.

mmkay..???

anyways on 450 f/r gc/konis.

 

lol, my car oversteers with my stock springs/shocks if I try hard enough

umm technically it wouldn't be oversteering. its more like losing control or having bald rear tires. if fwd vehicles could oversteer easily..........

rotation. The car is near nuetral now, but still understeers a little.

It's a little rougher than stock on irregular roads, but I don't find it too bad. It's certainly not in a different ballpark from the stock setup. The car still doesn't have enough oversteer though. I would prefer a little more.

The only way the car will oversteer now is by upsetting the weight ballance fairly significantly. Lifting throttle mid corner for example. I would never expect to spin-out on the street though. It's only on a autocross course where I'm gonna be able to upset the car enough to cause the back to rotate.

Before I mess with springs though I would like to get a RSB.

I have ATTS so when I'm going around a corner fast and I turn the wheel a little more than I should then the back end kicks out that's all. My tires are new so it's not that. It's just when I force it to oversteer.

 

Hey don't forget about adjustable coilovers too. I have 450 front 220 back(WAY TOO LOW) tein super street. I need to upgrade to type flex tho. But anyways I kind of jacked the back coilover to its stiffest.

 

How high can you go with revalved koni yellows ?

1000lbs or more. I'm not sure exactly, could be as high as 1200lbs.

 

400 front/450 rear. agx's are limiting me. i wanted 450 front 500 rear. this is for drag racing...

 

TEIN does that so people wont kill themselves with Oversteer. Werent the Prelude HA's like 740/400?

Sounds about right.....I believe the fronts have to be shortened as well. Corey was running 800f/1250r.
Limits on the off the shelf KONIs is much debated. I have read anywhere from 450-600. Obviously the higher you go, the less they will last. If youre planning to run 500's or something, I wouldn't bother having them revalved.
