Jim,

what kind of rubber caps are you talking about? Won't that decrease the clearance even more?

By a small margin. I have a big set of rubber caps and plugs that I bought from Eastwood company for capping off brake lines and stuff like that. A couple of them over the top of the adjustment posts would at least get rid of the sharp edges. I don't know if it would just make it more likely to damage the hood liner or not.

672/504???

That is correct. They are 672/504 (in lbs/inch). Tripoint recommends 500-550 in the front and 300-350 in the rear for a GC kit on yellow Koni's.

If that's true, then JESUS those are STIFF springs.

Yes it is "stiff," but amazingly it doesn't feel that stiff. The ride is VERY responsive, but not harsh at all. I prefer my ride with the JIC's over my friends ride with the GC springs and he has double adjustable yellow Koni's. It really does sound counter intuitive but the ride is actually pretty nice. It isn't jolting or harsh it is however very firm. One would think that with spring rates that high it would jar your teeth out everytime you hit a bump, but it really doesn't. It is kind of puzzling, but I gave up on trying to figure out why and instead I'm enjoying my new suspension.

By the way Jim. I have a lot of respect for you and so if I manage to say something that you disagree with then by all means say so. I mean no disrespect. I'm just trying to let you know about my experiences so far.

Jim,

I can vouch for that...it really doesn't feel that stiff, I had came from a stock touring suspension

ARD T2 04-18-03 10:22 PM

Ya it's some weird phenomena. It's all about the damping. That's kinda what I was getting at when we initially started trying to educate people about these. It's really weird.

I mean my FC is great, but even better is the Protege5 that uses the same rates as the FC. THe Protege5 has incredible ride quality yet the responsiveness is amazing. But I fluctuate between 1 and 7 on both applications. I have yet to go over that. I know these have enough damping range to go from good ride to kidney shaking ride.

Later, Rishie

Thanks for that comparison to the Konis Cody.

ARD T2 does jic have shock dyno sheets available?

artowar2 04-19-03 02:05 AM

Instead of using washers between the top plate and the shock tower, you guys could have a thicker top plate made, or a spacer-plate made to fit over the existing plate.

A thicker plate or spacer plate would give you the extra space that you need on the adjuster knobs, but avoid the concerns that Fabian raised with the washers. And unless you're running out of threads on the shock body, you can compensate for the added ride height.

Damn, am I really that scary? Don't answer that. :)

That's not a bad idea. I might talk to my fabricator about this. He can have water cut spacers made pretty easily, if people are interested. No promises, but it's definitely within his capabilities.

ARD T2 04-19-03 02:33 AM

I have ass shock dyno sheets. I don't know if JIC would release that information. I can always ask. I know companies release this information like Koni and so forth. I'd have to ask. If you require them I can put you into contact with them directly.

I and most of these guys can only tell you exactly that, how they compare to other suspensions they've been in.

I'm still awaiting to see what we can do on the manufacturing side to alleviate this problem. A remedy will be reached I'm sure. I'm sure it's easy too but has to go to the source in Japan.

G'nite, Rishie

I might be interested in this if JIC doesn't come up with a solution.

hey rishie.....don't hold your breath waiting on JIC to do anything.

jimlab 06-22-03 03:15 AM

Rishie, has there been any word on this? I've got a freshly painted hood and a brand new hood liner, and I'm not about to screw either up with a shock that's poorly designed, if you know what I mean. :)

I have a dozen other things to worry about before looking into having spacers made, but I'll see what I can do. If JIC is unable/unwilling to remedy the problem, that may be the next best/only solution.

Thanks!

Rx7-AIII 06-22-03 04:01 AM

I will second that. I was about to order a set of JIC's when this thread came out. Now I am wary for the same reasons. How frequent is hood touching from the adjuster. Is it just in a few cases or is the adjuster badly designed? Can the adjuster not be lowered relative to the top-mount on these units?
I want a set of coilovers that fit well and function well, I don't want to start having to modify mounts etc when spending this much cash.
Thanks

jimlab 06-22-03 12:52 PM

I'm not as worried about my hood. My adjusters are basically brand new, and if they weren't, I would have replaced them. In other words, if your 4 hood adjusters aren't worn out, you're probably not going to have a problem with denting the hood. Then again, I don't drop my hood to close it either. :)

I bought the JICs for the double adjustement (height separate of spring preload), never once thinking that there might be a problem with them. The rear shocks are fine, since they're under the plastic covers, but I thought the front adjustment posts looked a little tall. It wasn't until I installed my new hood liner and then saw this thread that I realized how close they come to the liner.

A spacer shouldn't be difficult to engineer, but I don't have any CAD software. Anyone know of a cheap Windows-based package that's easy to use? I don't think I'd get enough use out of a more expensive package to justify the price, but if anyone has any really good software they use, I'd like to hear about that, too.

artowar 06-22-03 02:47 PM

Do you really need the software? Why not remove an existing plate and trace it on some paper?

Actually, it seems to me that you could make a thicker replacement plate instead of a spacer. That way you end up with a one-piece solution.

Because I haven't looked at the shocks since I put them on the car, and I didn't know the plate was removable? :)

jimlab 06-24-03 02:08 AM

I removed one of the plates on the front shocks, and I don't think it's going to be a big deal to engineer a replacement "spacer" plate, with the possible exception of duplicating or maintaining the stock hardware.

I think the three allen screws that hold the plate to the shock body can stay, but I don't know if there's enough length on the "studs" that bolt to the car body to add 3/16-1/4" of plate thickness and still have enough to bolt to when installed, especially with a washer or shock tower brace added. I'll have to see if I can track down some new hardware.

Would anyone be interested if I were to have these made in bulk?

reza 06-24-03 10:52 AM

it did not dent my hood.

I don't believe they will dent the hood of anyone who doesn't have worn hood adjusters and doesn't drop or slam their hood, but it will still eventually tear holes in the hood liner, more than likely.

goku 06-26-03 07:30 PM

fix JIC coilovers
 
Hey guys


I heard about what is going on, and I talked to my boss.

and we will like to take care of this.

If you guys can call me and fax a receipt to me I will send you all a spacer.

That goes inbettwen the uppermount of the coilover and FD bracket.

It's just that on the FD's there is very little space of clerence bettwen the adjuster and the hood.

so will we take care of this

I will always take care of my FD customers ;)


Thanks,

Kris

Nice to see that JIC cares!

I am interested in getting one of these spacers. I bought my coilovers from Rishie, but I can't seem to find a receipt anywhere. Would it be of any use to have Rishie vouch for me?

goku 06-27-03 11:38 AM

yes I will.

rishies a cool guy, have him call me.

ARD T2 06-27-03 02:52 PM

I will vouch for all our customers. I am the one who notified JIC about remedying this problem ASAP. I've been getting a lot of people asking about dented hoods so i felt this should be remedied NOW. lol.

Thanks to Kris and Kevin at JIC for making this happen quickly. I just talked to them about it yesterday. lol.

Thanks, Rishie
