I have replaced my stock struts with Tokico Adjustables and now i want to replace the springs. I was checking out the racing beat website and they have their own Springs and Sway-bar for $429. I don't know doubt their products i think that they are very bood indeed. I also found the eiback Springs and Sway-bar for $476. I want to know which one would be better? I am into performance, and i have HKS intake and racing beat full exhaust, soon to add an Apexi AFC. I have an Bomex front bumper soon body kit? so i want to know which on would best fit my need?!

 

I thought that got their spring from eibach.


Don't quote me though

 

i think the difference is that eibach's are progressive and racing beat's are linear, so the racing beat's would probably be more "performance" oriented

 

The RB springs are a linear rate and the Eibach ones are progressive. The RB ones give a more crisp steering responce at the expence of the ride. The Eibach springs also drop the car a little less but its only .2 in. so its not really a bg difference. I've got the RB springs and I love them but I have never driven with Eibach's so I can really compare the two. I'm just regugitating information I've read here. I've seen lots of threads compareing the two, seach for lowering springs or something if you want more info than what I was able to give. I thought RB got their springs from Apex'I but whatever, they work, I like them.

 

eibach's pro-kit are also linear rate. Lots of people have had good success with them also.

 

I don't see the point in getting a progressive spring when you put on thick sway bars. I got my RB springs on my 7 last weekend and I love them!

Go with either one you want. I'm sure you'll be happy with either choice. If your into the drop, I think RB is an extra .2" lower.

 

I might be mistaken but the "pro" in the name of the spring means progressive not professional. Having said that the Eibach's are not linear rate. Mazdatrix has some info on their site.

I heard Racing Beat Springs suck! I heard they aren't stiff at all compared to stock springs and that they sag all kinds over time. Anybody know about any of this?

 

The last few posts seem to argue otherwise.

 

I don't have first hand experience with RB springs, however among all my suspension research I have not read a single bad review of thier springs.

 

I've heard things like that about Intrax springs, but I've never heard anything like that about RB.

 

I have Racing Beat springs/sway bars with Tokico blue shocks on the Miata.. I can tell you that the ride is sorta harsh.. It's definatly a harder ride than the 7 with Tokico Blues and Eibach Pros... but the steering is really, really crisp

I don't think you'd be disappointed with either, but if you're definatly not concerned about ride quality (or you live in an area with less pot-holes!), go with the Racing Beat.

Personally, I'd probably go Eibach again, but I live in Central PA, which is Pot hole capital of the world, I think.

 

first off I have RB sways and their are the same as the vert sways. Just a little bigger that normal ones so save yourself some money and grab some off a parting out vert.
Second I have RB vert springs and I am not really happy with them. If I had to do over again I would just get a coil over setup and be done with it. Also buying from ground control you can tell them what weight spring you want to run front and back to suit your needs. I will be switching out to a coil setup in the near future.

 

I rode my friends care and he had eibach springs and a racing beat strut tower bar, and his ride was pretty tight. The vehicle moved very precisely... when i asked him which would be better he said RB... that's why am not sure which would be better... Some one else had posted that they had a little problem with his Eibach sway bar (front) and wanted to exchange it for Rb because it didn't fit right in his car (which is a T2)...
I think that am leaing more toward the eibach but i would love to know more info on them before making the decision final... Thx

 

I was looking at some of the numbers and here it is...

Racing beat
Springs 1 inch drop
Front Sway bar is 1.125 inches
Rear Sway bar is 0.625 inches

Eibach Pro kit
Springs 0.8 inch drop
Front Sway bar is 28mm or 1.02 inches
Rear Sway bar is 17mm or 0.669 inches

I understand a bit about the drop, but can someone explain to me what do the numbers mean on the sway bars?

Thankx...

real cars are rear wheel drive...

 

The numbers are the diameter of the sway bars. The TII bars are thicker than the NA but I don't recall how much. The larger the bar the stiffer it is, however, just to open a can of worms, nobody list the type of spring steel used in any of thier bars.

The deflection rate will vary with the thickness and type of steel.

 

Thicker bar => more force to deflect the bar (assuming same mounting points and all) => less roll => firmer feel (and also less independant suspension right to left)

 

The racing beat front sway bar is about 23 inches or 3.75mm thicker when compared to the eibach front sway bar. In the rear though Racing Beat is 0.044 inches or 1.125mm thinner than the Eibac rear sway bar.
I would assume that having a strong sway bar in the back would be best because due to the fact that Rx's are rear wheel drive and when taking a curve the car seems to tail more having more control of the rear would be best. Anyone agree or disagree?!.

 

What you are talking about doesn't really have much bearing.. your car shouldn't be twisting that much so you should be able to control body roll rather effectively from either end of the car..

Beyond that, a general trend in suspension tuning is that a stiff rear encourages oversteer. Likewise a stiff front encourages understeer. Too much oversteer in a street driven car can get people hurt.

That was the much abbreviated and simplified version..

OT: when I communicate with people on the internet, I often shorten their screen name for brevity/convenience.. I was about to do that in this case as well, but realized that could be thought of as quite rude.

Is there such a thing as a dongon? or is the whole name from another language? just curious..

 

I just made the name up. I got it from a Hispanic Tv show and i have been using it since 1993 or so... I don't think it means anything... when i refer to dongon i refer to my D-_-_...
Anyways, about the whole sway bar case, the sway bar will give over steering if i get the eibach one? Am leaning more towards eibach because they are a little thicker in the back than RB and the height drop is not so low compared to the RB. I have a bomex fornt bumper and planning on getting the whole kit and an 1'' drop will not be to wise i don't think...

 

If you put both their front and their back bars on, I would think that you would be ok. I only say this because I doubt they would sell a product that's going to make your car _too_ unstable on the street (either company).
A swaybar doesn't do any height drop.. so I'm a little confused...

I just autocross my car, I know nothing of body kits and what clearances are needed for them...

Good luck.. stay safe...

 

I meant for the springs, they are not going to drop the car too low to the ground like RB would. Am just more concerned about the swaybars. Don't know which one to go for and that's all. I definately agree with you on that, i don't think that either company would put something in the market that was not safe. I will go this weekend to my shop and put on my Apex SAFC and probably dyno my car to get it tuned correctly and i might ask them which one would be best

 

Fitment issues can easily be from a previous collision. Im sure a big manufacturer like eibach makes precise fitting parts.

 

Anyone know the spring rates for either set? That would seem to be a good place to start.
