well the time has come to buy springs for my car and i'm in a mental battle with myself in deciding b/t the racing beat's and eibachs.

what do you guys think?

 

I have the RB springs, so I may be biased, because I haven't driven on the Eibach's. I'll let someone else chime in on their performance, and keep my testimonial to the features of the RB springs.

The RB product lowers the car noticeably and helps to lower the center of gravity, resulting in flatter cornering. Additionally, the heavier spring rate helps to keep the car flat. While a bit stiff for potholed backroads, on the freeway, the RB springs are just soft enough to absorb major bumps without making your fillings fall out. On smooth surfaces, the RB springs help to stick the tires down very well, and seem to be of a very durable design. Their red epoxy coating helps to keep erosion to a minimum and they also look nice in red - also visible when you look into the wheel arches or have the wheels and tires off.

For spirited driving and autocross, these springs really make a difference in cornering ability. I matched my RB spring installation with KONI front and rear stabilizer bars, so these are likely another major factor in getting the car to balance fairly well. On Michelin tires (treadwear = 650 - hard), it would 4-wheel slide with ease, and was really a lot of fun to drive. Since upgrade to Yoko ES100's (treadwear 280), I have a hard time getting the rear end loose, but you can corner at 40mph without even making a squeek from the tires.

Braking performance should also be improved, since higher rate springs will decrease weight transfer to the front end, and also help with rear lift due to the lower CG that lowering by 1" provides.

Springs are a very cost-effective upgrade to driving performance, but I urge you to keep your stock springs around for the day that you decide to go with something smoother and more comfortable. These are not for the faint of heart, and will decrease ride quality considerably for what you gain in better cornering performance. HTH,

 

I've heard the eibach springs are stiffer than the RB's? Am i wrong? If so im gonna switch for this is my dillema right now too!

From their tests the Eibach are stiffer in the front and slightly softer in the rear. Judging by the rates, the Eibach would reduce understeer.

 

How about the TMC springs? They are the springs used for Spec 7, and stiffer that they two you mentioned, and cost $139.

 

eibach. about 250.00 and lower the car about 3/4 of an inch. very good buy. have not tried any other brands.

 

You can contact Dave Turner Motorsports in SD CA for the TMC springs if you are interested. Here is their link - http://www.daveturner.com/
The part you would want to look for is CSM-400 "Street/Race" springs.

I did a comparison of springs a couple years ago, I willpost thyat link as well.

Good luck!

 

Here is the link with the discussion of various spring rates - https://www.rx7club.com/showthread.p...s+kill+no+cone

 

Does anyone know the spring rates of the B&G springs? www.shox.com has them for $200, and they lower the car 1.4", but Ive never heard of them before and I have no idea how stiff they are.

 

i like my RB's. the reason they are so good is that if you are using them for daily driving conditions they feal like stock springs, but when you take them on turns and really beat them they really kick ***....... some good tires and RB's and your set to tackle anything you will be coming across on the street.

 

I always heard eibach's are better...or at least that is what i am wanting to get....i guess everyone has their own opinion. I've heard good things about the RB springs as well....i own neither but am looking into it. Kill no cone's link he posted helps.

 

ive been happy with my ST springs
im runnin the st springs, tokico illuminas, and st front sway bar with no rear. set on soft for daily driving is nice and soft (to me lol) and set to hard works great for autox

 

I have eibachs, stiffness varies with the spring rates that you order.

I have 300lbs up front and 175lbs rear. I'd say that is borderline on unconfrotable but very responsive.

But I bought mine thru ground control, and they sell eibachs in pairs for fronts and rears. which is really good if you want to mess around with handling.

But if you don't want to bother with that eibach has the pro kit for the first gen it drops the car 0.8".

Check out Suspension Techniques they have a kit and which I was about to buy and they drop the car 1" full inch all around..... (they are cheaper than the eibachs in price!!!)

good luck!

 

i use my car at winter autocrosses and some rally type events

as such i am looking for stiffer springs but not keen on lowering the car at all, given the roads will be a little rougher.

any suggestions there?

 

thanks for the input. anyone else?

 

Does anyone no the spring rates for B&G and TMC springs?

 

Does anyone know the spring rates for B&G and TMC springs?

 

Run a search - I posted a table that had the spring rates of the TMC, RB, Eibach springs and others.
