Ground Control Rubbing

I have read the ntpog review of the GC/Koni set up. This is what I plan on using on my 5th gen. Is everyone using this set up experiencing the rubbing issue? If so what is the cure, just cutting the sleeves? How much do I cut?

I have GC and Koni setup and I dont have any problems.....
I had a friend of mine machine rings (like the press rings in the bottom) for the top. No wabbling here anymore. Let me know if any of you want to try this. I'll try to get some prices put together for a set.
What is the max drop you guys are getting from your Ground Controls? I have my fronts dropped all the way and my tires are still only flush with the tires
Seems like the rear has much more adjustablity. I can make the rears go way into the wheel well. I currently have my bumpstops cut in half and my shocks are set pretty stiff. The ride is stiff but handles like a dream! I am just wondering if I am hitting the bump stops being that low and only cutting them in half. What do u guys think?

Really? I drove around for a month with all 4 wheels tucked under the fenders.
Do you think I am stuck on my bump stops? How much did you cut off?

I cut off 1/3? I think. The smallest part of it. Maybe 1/2, I can't really remember.

Do you feel it bottoming out? I didn't think that the ride height depended on bumpstops? My understanding is that the bumpstops limit shock travel?
But I think you are reducing shock travel by lowering the car so much. Hence, the lower u are the less shock travel u have to begin with at a level position. I just think i may be resting on mine even though they are cut in half already. Do you have a 4th or 5th gen?

4th.

Yeah, I know what you're saying about the lower you are, the less shock travel you have.

So you height should be like this:
Sleeve-to-collar + spring + thickness of collar. (assuming that the spring perch on your shock and the upper mount is all the same as everyone else's
)

Travel is shock body to bumpstop, right? So if you're lowerred, that mean the bumpstop is going to be lower (closer to the shock body), since the shaft is compressed. But unless your shock is fully compressed (bottoming out on your bumpstop), the bumpstop shouldn't affect your ride height.

Good point....but if the bump stop is still to large or tall and you are reducing exposed piston (by going lower) on the shock, the bump stop can reduce your shock travel more causing it to sit onto of the shock body. Does that make sense? Are you on Konis, KYB or Tockicos?

Yeah, but that means your shock is fully compressed (zero shock travel remaining, not really fully compressed) if it's sitting on your shock body, which it shouldn't be normally.

I'm using Konis.

What perch setting are you using? I have KYB AGXs and I cant lower the perch. Does this have anything to do with it?

I'm using the middle setting, and the higher setting in the rear now. When it was super-duper-stupidly low, it was on the lowest setting. I kept bottoming out, so up it went


I think the difference was 3/4"? Something like that. At the lowest, I was running something like a 2 3/4" - 3" drop in the front, and 2 1/2" in the rear. Now I'm up to 1 3/4" in the front, and 1.5" in the rear.

Thats about what I'm figuring....a 2.5 - 2.75" drop. It seems to ride fine this way, just a little bumpy. I think I am going to raise it a hair. Did you find it handled better at the height you have now or did you do it so you didnt bottom out alot?

I liked it when it was lower. Very flat, very little body roll. But also very little shock travel and so I bottomed out ALL THE TIME, which totally sucked and wasn't worth it.

I find that making the shocks stiffer can still take out some of the body roll, so I'm happy at this height.
Thats good to hear. What spring rate did you get and where do you have your Konis set at?

400f/275r
Konis are set at from stiffest. In the rear, 3/4 to 1 turn, and in the front it's around 1 to 1 1/2 turns.

From full stiff to full soft seems to be about 2 3/4 turns.
I got the 400/300. The ride isnt too bad, but now that I have them cranked down its a bit rougher. I have my AGXs set at 3 out of 4. Which is about 3/4 stiff. Handles like a dream tho! If I put them on 2 it seems alot softer but doesnt perform as well.

By the way. do you have a setup on hondaprelude.com?

I have them pretty soft
Almost halfway on both front and back. The reason I did that was to give the suspension some give
I noticed a lot more rollover on my tires when I was riding them stiffer.

So I've since adjusted to having the suspension come into play a bit more, and not have to factor in the tires rolling over as much (which is good for me, because I couldn't really tell while driving when this was happening
).

I think I have a setup on hp.com. It's been a while though, I think I joined there in '97 or so. You can see some pics of my car on h-t.com too.
