Well, to be honest, the reason I'm looking into the coilover is that I need to spend the money on some new shocks anyway, so if I'm gonna go to coilovers eventually anyway, I might as well make the jump now. My front shocks are on their last legs (I'm getting some severe rubbing on the left and right sides of the car on hard cornering, and I'm running a completely stock suspension with stock rims and stock sized tires, the car also feels sluggish and wobbly around turns).

I'm slowly learning and modding the car, unfortunately most of what I have learned has been from the car breaking down, and I figure while I don't ever plan on putting the car on a track, and the $1K will be a bit of a hit on the wallet, the investment looks to be completely worth it.

Thanks again for the input rynberg, very much appreciated man.

 

Have you had a good shop check your suspension out? It's very hard to believe you are getting bad rubbing with a completely stock suspension and wheels/tires. Are your front sway bar mounts ok? Are the front shocks visibly leaking? When you hit a bump, does the car snub back down or does it bounce a little bit?

I won't argue with you that a $1000 set of coilovers seems like a good deal if you are replacing dampers and want to lower the car at the same time. Especially since the coilovers will replace the upper spring mounts, which are likely toast. However, something to think about is that the dampers on most coilovers rarely last more than a couple of years before needing a rebuild. Where will these Apexi's be rebuilt? Do you have to ship them to Japan? Most likely, you will just have to replace the whole unit.

Just some things to think about.

 

what is so bad about taiwan?

 

What bothers me more about these than taiwan is that they appear to have the same spring rate front and rear?

 

Hmm, gotcha, didn't even think about the front sway bars, will need to take a look at those. These are some good points rynberg, will seriously need to coinsider this. So what about getting a set of new shocks, I'd have to get a new set of upper spring mounts in addition to those too then?? To be honest, I'm not really looking to lower the car much, would be just as happy if the car is the stock height (I'll probably get some 17" rims in the near future though). Figure if I'm gonna be looking into replacing the springs, shocks, and mounts I'm looking at over $1k anyway, so I figure'd I'd might as well go for the coiovers and be able to adjust the ride quality to my liking. These are some good points to consider though, thanks a bunch man.

 

looking into these, seem to suit my needs , can someone direct me to some for my FC? not able to find much buying info on them.

 

hey guys i bought it, they arrived yesterday, but in the Apexì EXV coilover there wasn't user manual or istruction, where i ca find it on the web??? Did you found any user manual on the coilover????

Let me know

 

about shocks/springs and sway bars...

when do these need to be changed? how will i know that the sway bars are ready to go... there's 73k on my fd.. i think i will i have to change some suspension bushings.. shocks.. springs..

is 73k a typical time that suspensions will need to be serviced on fds?

great read on the coilovers, lots of info

 

hello guys,

Because i have to mount the Apexì EXV coilover and i don't have the user manual , there is some one that can help me to send it via e-mail????
Thanks i wait for you!
Have a fun!

 

I have the full instructions in English but no scanner to make it available on the internet.. If you need any specific help just let me know!

btw, the instructions do not include any helpful advice on installing them

 

Ok guys, don't mean to hijack the convo again, but I've been doing a little more reading, and what I get from it is that you relly don't want to ever have a spring rate higher than 550 in the front and 450 in the rear. from what I understand, the Apexi EVXs are 620+ front and rear! I'm atarting to second guess these coilovers and starting to look at the Tein Flexes, but for the guys that are running the EVXs, how does the car handle compared to stock? Does the back end like to come out more? I heard that you only really ever want to use the higher spring rates for drifting.

Oh, and Rynberg, just a follow up dude, ifrom when you asked before about the car's reaction on bumps, it's definately a lot different from when I first had t he car about a year ago, the left side of the car feels like it dips a little more on right turns than the right does on left turns (guess that makes sense with my extra weight, but it didn't do it this much before). Also, when driving, I know I drive an R1, but this is rediculous, I literally feel every bump on the road, even on straight roads, and if I accidentaly hit a bump at speed, the car seems to bounce a little more, like the car tkes a little more time to stabilize. Any ideas on what might be wrong dude?

 

If anyone wants a set of these I have one left in stock.

Jason

 

I have to mount the coilovers, what i should know?? about the height what they say of important that is not common???
Thanks you very much.
Best Regards

There was recently a "2005 street suspension tuning" test in japan where Yashio Factory and MCR tested a RE Amemiya FD. What were the spring rates? 16k front and 18k rear. Also FEED runs 18k front and rear on its "street" shop car. Its all in the dampers.

As for the taiwan thing, it could be possible that they outsourced the work to taiwan to make the product cheaper. That doesn't mean it wasn't built to Apexi's specs. This seems to make since because now after the Apexi coilovers have been put out, Megan Racing released "their" circuit spec coilovers with the same spring rates from Apexi....so yeah i think they designed how they should be valved and the taiwanese manuf. built it for them.

 

can you ask mcdonald to make u filet mignon? imo, they simply can't match the performance of a real racing damper with the type of technology they are using. You can valve any damper to look similar on the dyno graph, it doesn't mean they'll perform the same on the road. Most of the tw coilovers are made by the companies that produces oem dampers.

I've also noticed many jpn tuners are using same spring rate front/rear, perhaps they are using no rear sway bar? There is probably a good reason why they are doing it. I'm curious to hear their reason behind it. This appear to be a trend in many other recent jpn tuned cars too.

just my 2cents

 

Hey guys, please anyone can send by e-mail the user manual??? just the most important page to how to install, i'm waiting to you before install the Apexì EXV coilover, please!!!!
Thanks

 

Well, from what I have found so far, it looks like one of the major pluses about having the same spring rates the same in the front as the rear is that it will let the back end come out a bit more (basically induces more of a drifting type of car, which seems to be the major fad right now). I did read off steve ciriani's website a comment from someone that said that the spring rates really don't matter as long as the dampener can complement it, so I guess that makes sense. But then in the case of the same spring rates in front and back, can anyone that have the EVXs on their car comment on the car's handling? Not just ride comfort, but cornering ability compared to stock?

 

i want a set of these but i am still alil skeptical. and u guys aint helping, lmao

somebody please give a str8 answer

 

Anyone that says spring rates don't matter and can be "fixed" by the dampers, doesn't know what the hell they are talking about.

You want real answers? Search for posts by Howard Coleman, there's even some in this thread! He is a 20+ year SCCA racer and knows RX-7s very well.

 

Please help me, on this link take the page number 5.

I need to know the reference value for the Apexì EXV coilover, otherwise i can't install it, please tell me wich excample i have to take as reference and the value.


Thanks and Best Regards
Pietro

 

The reference value is just the ride height...set the height so there is 25-25.5 inches (635-648mm) between the fender arch and the ground. Alternatively, you can measure from the center of the wheel hub to the fender arch -- just divide my numbers in 1/2 -- 12.5-12.75 inches (318-324mm).

 

more or less. there is no need for spring rates that high on the street. it'll make the bumps you're complaining about feel even worse.

it sounds like you might have a blown shock. pull the wheel off and see if there is any wetness or oily residue around the shock. first sign a blown shock when the oil leaks. might also want to check the condition of your tires and alignment.

 

oh and before pissing away all your money on a suspension, might want to have it looked at by a rotary shop if you can't determine this on your own.

 

Ha! I feel so smart compared to some of you guys.

 

well i copped a set from Chuck...my boy at Rotaryextremes....i'll keep you posted on the results.
