My rear ground controls have a ton of space between them and the perch when I jack the car up.

I've noticed when I take very hard right hand corners where the rear tire leaves the ground, the rear passenger side spring will come off the perch, and when the wheel comes back down it will make a thump sound.

Is this normal? Is it okay? Or do I have the wrong rear springs?


Here are some pics:
This is the rear passenger side in question


Another shot of it:


Another shot of it with the spring down:


For comparison, this is the rear driver side which makes no noise:

 

Why not get a helper spring to alleviate this concern?

I have a similar situation on my AE86 with GC sleeves... I hope it doesn't become a problem at the track.

I am considering GC's and would also like to know the answer.

 

seems to me that one of your springs are stuck up on the perch. when i jack up my car, the springs lays on the perch and doesn stay up.

 

you need to DIY extend your top hats or buy the GC ones.




this will pull the shaft higher. The custom DIY ones are best though IMO because you can make it higher. It takes away the slop from the way the springs seat.


ken from benen made me a set for my old ride and here is the DIY for it.

This is in regaurd to H-T Thread:
https://honda-tech.com/zerothread?id=469012#4884162

Tools needed:
-Measuring Tape
-Hammer
-Hack Saw
-14mm Wrench
-Alan Key Set
-Welder

So here goes.....

Step one:
Remove shock from car, measure huge gap that makes car bouncey.



Step 2:
Take apart shock perch and remove studs





Note: put nut on stud to protect threads

Step 3:
Cut bushing cut off perch.





Caution: edges are very sharp, so make sure to file down





Step 4:
Get a length of tubing and cut to desired length (1 Inch or 1 1/2 Inch, depending on space between hood and top of shock)



once again file edges!!!



Step 5:
Weld tubing to shock tower.





Note: Be sure to weld on the inside of the bushing tower cup

Let the top cool...




Step 6:
Reassemble perch w/bushings and put back on shock.



"Aerosol over haul"





Wow Lookie: same ride hieght with more shock travel!

Yes, I have a vested interest...I sold Jond that set up! I used a Mugen 26mm rear bar so didn't notice the un-seating during cornering on my car.

What you are seeing is normal, however it looks like the lower end of the spring is wearing the perch as it re-seats. The upper end of the spring is staying stuck in the rubber upper seat, which is also normal. Helper springs or a stiffer rear sway bar will lessen the effect.

To be clear helper springs (per my understanding based on my coilovers at least) would remove the effect entirely.

Where would one acquire helper springs that will fit/work with a GC sleeve setup?

 

We make helpers and GC sells them. Just call GC @ 530-677-8600. Part number is "Helper250".

That, and the associated cost, are the $20,000 questions.

I suspect that Eibach or any other spring manufacturer would have a helper spring with associated plastic spacer/hat. I'd just give 'em a call if I were you.

Yepper. I started the post before you posted and then submitted it late. lol

Btw, these helper springs will effectively create a progressive rate when you combine the two, right? Do you have links to any pics, etc?

...and do you know if they come with a plastic spacer/hat/seat for between the two?

A "helper250" will simply help hold the main spring in place. We have linear and progressive tenders (in various rates) which will give you a dual rate. You connect any two 2.5" ID Eibach springs using a "spacer250".

That's really helpful -- thanks a lot for the info.

very informative thread! thanks guys!

weird. I work with jond and called gc for him yesterday, explained the problem, and even asked if they had a helper spring or something to help, they said no.. guess i talked to a new guy or something? lol

 

you could also get a longer spring.


thats crazy that you have that much droop.

Sort of Off-Topic, but could anyone provide any insight as to why the GC top hats are labelled as "race use only" ? What would be the dissadvantage of using them on the street?

And i'm asuming its for the rears only (on an integra at least), or would they clear the front hood on the front suspension?

 

I had the DIY set up in the front and I tilted my hood so it would clear.

probably because their sleeved coilovers are also "race use only" (e.g. liability )

No big deal, Just DOT rules(I think), they go on about not being able to Modify/Change major suspension or chasis components with an engineers certificate. So people that manufacture these sort of parts, put 'Not for Street use'.
Just keeps the manufactures clean and clear of any fallout from failures.

Like I said 'I think..' otherwise someone will correct me.

Later.

 

Thanks for the clarification, I thought maybe the GC top hats were specifically designed "not for street use" and should really not be used on the street, but if its all just to cover their behind, then thats understandable

 

the mounts that i re-fer to as "race use only" or "race" mounts. are the monoball- height adjustable ones. i haven't heard of these as "race use only". But in a lawsuit happy soceity i wouldn't be suprised if they had to do something like that

 

Great info! Thanks
I think I'm going to order Top Hats. It seems like thats the better of the two options?

Its an awesome setup
Now that I have the ride height, shocks, and tire pressure dialed in, I'm completely loving it! This thing has to be pulling pretty close to a G of latteral accel.

I may end up getting a bigger rear sway bar, I cant make up my mind. I like the piece of mind knowing if I overdrive my car I wont spin it, but I also woulnt mind just a tad more rotation...

I have them on the front. It gives more shock travel which is needed.
The only modification you need to do is cut two small notches on your strut tower bar and they fit.
