Yea....cuz i was thinking about gettin the eibach pro-kit springs, or the Racing beat vert springs. What do you guys have and how are they?

I have the vert springs from RB. They drop the car a little and are very stiff. Don't replace springs without doing the struts

Cobra_R

yea, ive already decided on the struts, im just trying to decide on some springs.

spoolin7

i have some cheap intrax they are cool with some kyb'sgonna switch to a tein setup soon

Sorry to hijack, but while we're on the subject...
I bought new factory struts right before RB came out with their vert springs. RB says you can use their springs with the stock struts, but is that ideal? I would think the stock struts wouldn't have enough damping control for the stiffer springs. What does everybody think?

Cobra_R

ive heard companies, and people say that you shouldnt use springs that arent made specifically for the vert because the vert is heavier. what do you guys think about this? Are the springs not made for the vert to soft? the reason i wanted the eibach pro-kit springs is because the spring rates are higher than the RBs. So the springs should be stiffer right?

I got the full RB vert suspension package springs\sway bars. And Tokiko 5 way adjustable shocks. The springs are a small 1/2 inch drop. I would have liked a little lower but I don't want speed bumps to start becoming an issue. Looks very nice with some 18 inch wheels. I dunno if I would actually drop it any lower with the 18 inch wheels. Handling is greatly improved now.

I got the whole Tein package installed......


In Mustangs it is essential that you only use vert springs on a vert....but not too sure about a RX7....... but if they make a set specifically for something there usually is a reson.....

whats the difference in rates on the RB vert vs. regular non vert RB springs?

RB non verts are front 145 lbs/in rear 132 lbs/in what are the verts?

Cobra_R

the front is 130 and the rear is 80 on both the coupe and vert springs according to mazdatrix.com

anyone ever heard anything bout this company? Good products bad products? Theyre really cheap which makes me wonder about the quality. Anyone ever used them or have any info bout their products?

BinaryRotary

Yeah, they're cheap Taiwanese ****. Make your car ride like you've got 700 lbs of bricks on both front and back.

Cobra_R

haha....so if i were to put springs that arent made for the vert like the eibach pro-kit on, it would just make the car lower than the amount the car would be lowered on a coupe right, cuz its heavier...it wouldnt affect the spring rates, or lower the car more in the front then the back or anything like that?

BinaryRotary

Your best bet is the vert specific springs from Mazdatrix, no quality or ride problems with those.

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.

Cobra_R

haha...cool thanks...that helped a lot, i plan on gettin the AGXs, if u dont reccomend the eibachs for autocross, what would u reccomend. if the spring rates on the vert RB springs are the same as the rates on the RB coupe srings i might get those instead.
thanks

hanman

I have Eibach's with Tokico Illumina's (adjustable) on my 88 vert. I like the ride. It is much harsher than stock, but it handles much better than stock. It lowered the car noticeably, but nothing rubs. I autocross it occasionally and it is fine. If you really want to be competitive I doubt you want a second gen RX anyway.

hypercoil race springs =)

STR8BALLIN - R

both have the Eibach springs and their comments are contradictory! One says softer, one says harsher.............
hmmmmmmm............
doesnt really make that decision much easier

Cobra_R

haha....nope.
what are hypercoil race springs?

Read both posts. Compare carefully.

The comments and driving impressions are *not* contradictory. You should notice a difference in our setups. It makes perfect sense to me that his setup is harsh and mine is not. In fact, I would be surprised if the two different setups yielded the same ride because they are *different*.

If you can't figure it out, post back. I will 'splain it to you.

Cobra_R

well, you mentioned that you wouldnt reccommend the eibachs for autocross, is that because theyre progressive? or is there a different reason?

jackhild59

OK, second question first. I wouldn'd recommend them for autocross because the initial rate of the springs is softer and that would allow too much vertical (up and down) movement. I believe that would upset your transitions. This only applies to my setup which has Tokico Blue shocks.


Now to reconcile the question raised by STR8BALLIN - R. I said that the car was intially softer (first couple of inches max) then dramatically firmer. I also suggested that the situation might be better with some adjustable shocks.

hanman says his is harsher and that it is fine for autocross with Tokico Illumina adjustable shocks.

hanman confirmed my speculation. He has eibach pro with adjustable shocks. I believe the illumina's can be set much firmer than the tokico blues. And I bet hanman has them set firmer, otherwise, why have them? I would expect his ride to be much harder than stock. My ride is both softer and harder depending on the suspension loading.
