First things first, I searched, advanced searched, the search on ht sucks end of discussion. Their is no one comprehensive thread for all coilover options?

Okay I have a good friend who is finally getting is car out here on the west coast. A 94 integra with a laundry list of mods putting down 443whp at the moment. He asked me to help him research suspension options.

Now I come from macpherson struts, where ride height, spring preload, and dampners are all indifferent from one another. Apparently not the case with double wishbone?

So I do some research and most companies recommend a mild drop between a sweet spot. Well were trying to trying to stance it out, and to do so where it needs to be low. I was thinking front spring rates around 8k and rear around 10k.

Is there a company where you can order custom spring rates? Budget 1-1.5k, sorry I come from 8th gens don't know where to start.

I'm checking this out, but the rear springs are weak for this power he's putting down. http://www.ksportusa.com/asp/coilove...roduct_id=cd01

 

ground control

 

Research the Ground control/Koni setup. Best bang for your buck. You can order the entire package with custom spring rates from several sponsors on here.

 

That isn't true, regardless of the suspension design.

If you come from working primarily with strut based cars, going to double wishbones just means:
* The camber curve means a lower static camber value can be used.
* The car will take a larger lowering before the RC position starts causing issues.
* Motion ratio actually needs to be considered when considering spring rates.

If that doesn't make sense, then you aren't knowledgeable enough about suspension to worry about the difference between the 2 designs, so don't worry too much about it and just buy something off the shelf.

 

Mhmm well I'm checking out ground control's website now. It just seems their all spring/strut combos? And you adjust ride height by moving the spring, which isn't affecting the pre-load? I want ones where you can dial in the dampners your self, not just a "shock".

These good? http://www.ground-control-store.com/...p/II=825/CA=73, but the pic shows they're barreled springs? His is a 94, this shows 96 up I wouldn't think it matters?

 

A shock is a dampner (thanks, I just learned why everyone mistakenly calls shocks dampeners). If the shock is adjustable, that means, by definition, you can adjust the damping.

Pre-load is not something that you can adjust separately from ride height with a fixed length damper. It is also not something you need to worry about, at all really.

If we're talking Integra suspensions, 94-01 is all the same thing (except the Type-R), in terms of what fits.

Those look like standard coil springs to me (which is what GC kits come with, they use Eibach ERS springs), and not a barreled spring.

 

Just threw on a set of function form type ones. Ride is great and I can go with whatever ride hiegth I desire.

You may want to check them out. Price doesn't seem to be an issue with you but doesn't hurt to get what you need at a decent price.

There ya go, give these guys a shout and tell your buddy to pick up a Stage 1 or 2 package from them (Stage 3 with rear top hats isn't really needed).



And no it doesn't matter that there will be no spring preload at full droop. Unless tires start coming off the ground, the spring isn't going anywhere. And even then say if you lift the inside rear tire on a hard corner, the sway bar will likely keep the spring seated.

And like Tuner mentioned, with double wishbone you have to consider motion ratios when adjusting ride height. Since the shock is bolted to the LCA inboard of the wheel hub, changing the spring perch height one inch for example, will actually change your ride height around 1.5 inches, for the front suspension on an Integra. Rear would change a bit less.
