Anyone ever do an install with these? How is the ride quality? I was leaning towards an Eibach pro kit when I saw them. They are claimed to have a 1.5" drop front and rear as apposed to Eibach's -0.8" and still retain "drivability". Is this acurate? Still considering a set of Tockico blues to go with. Any bottom out issues with these struts going this low?( I mean the struts themselves, not the car) Any expertise would be greatly appreciated. Other than the obvious, allignment, caster/camber adjustments needed.

I installed some tanabe gf's on a set of tokico illuminas, the ride quality is awsome! a little stiff but not that bad, im sure if you put them on blues it will be a little softer (since i set my illuminas to stiffest front and back) It does drop your car a good 1.5 inches, but to me it no really that much, looks good, decent drop. everything fitted perfectly

I just installed some last week, awesome drop, it looks beautiful, and the rise quality is great, well I had cut springs before so that's what I'm comparing to...

I installed a few sets one of them being revitup13b's and they ride nice. ride height change will depend on how saggy your current springs are. handling is great.

Great info guys. Anyone have before/after shots of their car with this install?

I have the GF210s Not bad for ride quality!

I just bought some tanabe gf's last month, Im installing them with kyb adjustables. I will let you know when they are on the car. My cars sleeping for the winter. SHHHH.......

I still trying to figure out what tires I should run on my 16's after I drop it.

Hay ya'll. Just came to find out that they don't make a vert specific spring. Yet another dead end. Im back on the hunt!

Don't give up. You might want to rethink after reading some threads:

https://www.rx7club.com/2nd-generation-specific-1986-1992-17/convertible-lowering-springs-501516/

Basically, the necessity of vert specific spring is bull. I have eibach and love them. They were supposed to drop by .8", but the drop was much less over the saggy oems. My eibachs are about as low as I want. I don't know if I would want another .75" drop l like the tannabe's, but that is a personal decision. I just drove 700 miles over 3 days in my vert. On all sorts of roads, interstate, broken urban concrete, 2 lane back twisties. I wouldn't trade the ride/handling for anything.

If your choice is a good choice for the coupe, it will work fine for your vert.

I have GF210 and KYB AGX's They are my favorite spring i have ever used but I wish they dropped a little more, you will need a rear camber adjusting rod after doing this also or the will have negative camber wear over time

Thanks Jackhild59. Didn't happen to catch who started that other thread, did ya?! I'm still looking.

So, is it B.S.? Can you really run coupe springs in a vert without consiquence? There is a weight difference between the two. I don't want to loose the preliminary buffering of a progressive rate spring by overloading it. Anyone else have any input on the subject?

Here is my Turbo II with Tanabe and KYB AGX it will give you an idea how low it will be

Drift_Kid

i have a set on mine and it did stiffen up the suspension. but i wish i had gone for the stiffer RSR race springs. but i do alot of drifting so i like my ride stiff... oh and be ready for the snap over steer while cornering cuz they are a grip set spring so once you start to slip it'll throw you pretty good. but it could just be from the blown rear strut i have "soon to be replaced with kyb agx" and or the toe steer. but i noticed it snaping out more after the spring install.

Ya, that blown out strut is definitly causing your car to wallow in the turns. As for the steering, if you havent done an alignment since the spring install, then you aren't getting the full benifit of your new springs.

SO....IS IT B.S. OR NOT??!!! Can I run coupe springs in my vert without reprocussion?

FC3Stech-- I like the ride height on your car man! With a nice body kit I think it would make my vert look great!

peacekeeper

Well, what spring rate does your car need? What rate do you want it to have? Do the springs in question have the correct spring rate? If the springs have enough of a spring rate to safely load with your car, then you don't have anything to worry about. You probably don't have anything to worry about. The vert isn't that damn heavy.

O.K.--So here is a mind f@$k!!! I just cracked open my handy dandy owners manual. And what did I find in the spec section? G.V.W.R. (or Gross Vehicle Weight Rating for those of you who didnt know) for a non turbo coupe is 3635 Lbs. and a vert is 3394 Lbs.!!!! That makes the vert weigh 241 Lbs. LESS than a coupe!!! And this whole time I thought it weighed more. Silly me......

lov-2-rev

iTrader: (87)

By the way. Turbo models weight the least at 3340 Lbs. But not by much!

OK great...now I'm really confused! So, how much does a coupe weigh and how much does a vert weigh?

Sideways7

iTrader: (7)

According to the sticky at the top, the Manual coupe weighs 2720, Turbo weighs 2850 and the vert weighs 3003. I don't think that 150 pounds over a turbo will matter since the driver's weight can differ by that much. Also, the s4 vert only weighs about 50 more than an s5 turbo, so thats even less of a difference.

lov-2-rev

iTrader: (87)

OK. I'm cool with the weight difference between the turbo and the vert. No big deal. NO HEFFERS!, thats all. Now....Is there any difference in the spring and strut design between the two versions? Anything that would not allow me to install turbo springs on my vert?

I have eibach prokit and tokico blues on my vert.

I was told all sorts of BS by different people about springs on verts. One web site selling RB and eibach to the RX7 scene emailed me back that the vert was 800 lbs heavier than the coupe. Yeah, right after I fill the trunk with concrete!

I was told that the eibachs would turn into a 2-3" drop and that everything would rub.

Total BS.





Probably won't be trusting them for advice in the future!

Your 1988 is only 150 lbs heavier than the 1988 turbo II. That is the weight of one fat chick. Anyone who thinks that difference is going to mess up the handling of your car is just wrong. Might affect your social life, but that is a tale for another day.

My springs are for the Turbo II coupe. The eibach prokits dropped my car 5/8" -3/4" depending on corner. Noticeable and it looks nice, but not slammed. The oem springs must have sagged a little because the eibachs were supposed to drop a little more than that, more like 0.8" on a coupe. So it should have been a little more drop than the coupe. The eibachs are progressive and the car is much nicer to drive. Pavement impacts are greatly reduced. The car is much less harsh than before. There is less noise and rattles from the car body and interior when hitting pavement irregularities.

Bad part. The car feels a just little soft on initial turn-in. Much less of a knife edged handling machine. Thow it into a corner and you can feel the soft part of the progressive spring compress. Just for an inch or so. Then the suspension firms up dramatically and it becomes much firmer than the oem suspension. The car is actually faster around a corner after that. I don't like the feeling dduring that brief transition. Probably some adjustable struts would allow you to add come more control to firm up the response in that upper soft portion of the suspension travel for a substantial improvement in turn-in.

It depends on what you want. I wouldn't want a firmer spring than the oem, especially with a single rate. The vert with the top down is a fairly stiff platform, but it is still a convertible and harder springs would make it into a rattle trap.

I really like the drive of the car, but it took some getting used to in the twisties. It is totally predictable, easy and fast to drive.. The car has a more refined ride and character. More of a GT, less of a hard edged racer. I would not recommend the eibachs for autocross unless you had some Koni or AGX or Tokico adjustables, and then only maybe.

Hope that helps.

By the way, after you do the struts and springs, GET A GOOD ALIGNMENT! It makes all the difference.

yup, but then that is a built in advantage to us vert drivers; we get to date thinner women. It is listed in the owners manual, somewhere.

And by the way, mine are the turbo part number; I think there is about 5# difference in the intitial spring rate on the rear spring only, per mazdatrix.* Not a big deal if you were buying used, if buying new, get the turbo part.



*Of course, they also say that verts are #800 heavier than a coupe...
