condor : The corner/edge of the rear tyres are got scarred during my last trip.
GTO : Wider tyres?

Yes -185, instead of the stock 175.

Had not seen how much the shocks were sitting down till during a break after completing abougt 80% of the journey. But by then the tyres had twice scraped the edge of the wheel arch. Each time at 100+ and when coming out of mild un-dulations in the road.

I'm sure they'd use some sort of leverage. More than just finger squeezing.

Again, Rush - please describe the details about how it was installed.

In effect converting it into a dual-rate coil spring (rather than a rising-rate coil), is that right
Don't think so.

So this works on the principle of adding preload to the spring only? It doesn't look that way...

IMO, for a particular coil, the interposition of a compressible rubber strip in between the coils increases the spring rate for that coil (irrespective of whether it is installed at the top or bottom of the spring), without changing the spring rate of the other coils - which is how a dual-rate spring is supposed to work anyway.

I would say chaps, very innovative smart thinking by someone, without doing much of a mod job. But have some Questions and thoughts :

Questions :

- Seems like a Free size built to suit every coil spring (or am I wrong ?)
- Whats the break load it can sustain (for eg, can you put this in a 2.5 tonner Safari and carry it ??)

Thoughts:

- Quite a DIY job, easy in - easy out
- Good to get instant GC increase too.
- Like someone mentioned, it doesnt have any locks, God forbid if it slips off, that too only from one of the springs.
- Will impact the handling under high speeds.
- Aerodynamics should also be a concern.
- Life should depend on the Vehicle its used on, heavier vehicle should lead to lesser life.

Yes

Yes

- which is how a dual-rate spring is supposed to work anyway.

The second rate will come into play when the 'normal' coils are coilbound, and can no longer act as springs, but the tweaked coil still has some travel. I think the normal suspension will hit its bumpstops before coils become coilbound.

I suggest you wait till I complete atleast 5,000 - 10,000 kms (including a couple of highway runs) before going ahead with the install.

Also could you please reccomend how to choose the size we would need? 1 inch did the trick for you.

Best to speak to the manufacturer : Darryl 98210.47448 / dxmenezes@yahoo.co.uk Psycho said 1 inch is best for the Civic.

From my experience of polymer products made here, I would change it every year, at most every two.

Thanks!

He's still recommending 1.5, but I'm happy with 1". The car is rarely loaded with 5 + luggage anyways.

I wonder why tyre wear should be an issue with using this

Don't quote me on this, but IIRC, it was mentioned that the camber changes slightly.

My only concern too. Time will tell.

Exactly. The coil was NOT removed. The car was lifted up on a workshop hydraulic lift.

And what was the change in suspension geometry noticed, when wheel alignment was checked after installing the device? Rush, could you enlighten us on this please?

Getting the wheel alignment done on Wednesday; will update.

OT: I mistook the fellow's shoes for some kind of suspension component at first glance!

Nope. Should it? Is there a chance of it moving down the spring order?

How many kms on your existing suspension? My friend's Ikon runs 185 without issue. What's your tyre profile?

He has a variety of sizes; says to choose them depending on the gap in your coil springs. IIRC, the max was 2 inches.

Will ask him and update.

Done 21000 km. I'm running on 185/60 R14 (Stock is 175/75 R13). So only difference is the extra width.

But that day the car was really loaded. The boot was full, and I had stuff in the co-driver seat too, apart from 2 passengers in the back. The rear wheels were looking exactly like on your Civic here.

[sgiitk]

Very interesting. Maybe godsent to all of us struggling with the rear end of the Civic - even more so the pre 2009 owners.

I will say, keep and eye for further experience. I am adding a link to the Civic maintenance thread.

[mdsaab]

@GTO ~ thanks, will await your future report before taking the plunge. Here's wishing you take longer drives and maybe a golden quadralateral endurance run to complete the 5 - 10k kms Asap.
i know a 400km drive is coming up soon.

Jaggu, his answer : There is no stopper. That's the reason I suggest a tight fit. Once the soap dries, the rubber grips the spring tightly enough.

He has a variety of sizes; says to choose them depending on the gap in your coil springs. IIRC, the max was 2 inches.

Correction : His size ranges are from 1/2 inch to 2.5 inch...the latter is for SUVs.

[sumeethaldankar]

I was up a Automech (Lower parel) yesterday for a muffler change on my 800 and Vivek introduced to me the coil spring thingy.Its costs around 4500 bucks for all 4's and they are giving a 5 year warranty(don't remember the max kms) on the same.

He even showed to me the adjusters fitted on the Automech's owners Innova.Vivek mentioned the adjuster would help prevent the vehicle from bottoming out and improves ride and handling.

[iTNerd]

This is great boon and tweak for civic owners and I hope this is NOT an April fool prank!

Yeah, Automech & N1Racing are the Mumbai dealers for AutoRunner. I don't think an Innova is a good choice for these though; for one, it already has a firm enough suspension. Second, raising an MUV by 1/2 - 1 inch is not a good idea.

You won't ever find an April Fool prank thread from me. People take Team-BHP seriously, and I greatly respect that.

[lancer_rit]

wow, very interesting thread GTO :-) This might be also helpful for those who don't have a GC problem but would like to stiffen the rear suspension a tad. My Lancer has GC of 187mm (after upsized wheels, stock is 185mm), but HM has tuned for comfort. So while low speed ride comfort is great, it does have up and down movement at speeds on rough/undulating surfaces!

So, will keep an eye on your updates!

[pratikraveesh]

Any idea on how this stuff works? Could not understand it's working clearly, explanations would help. Why does the stress level on spring and tyre wear increase?

[raghav.carfreak]

Any idea who the dealers for the same in bangalore would be?
Although i would want to wait awhile before I actually consider this upgrade,Looks really VFM
