im looking to find out what springs are the stiffest but also offer the least drop, sumthing less than 1.25". reason for this is that im putting them on a heavier Mazda.

and i did search, opions varied so much. is the RB spings what i might need ?

stiffest??

I would try the Tanabe GF springs, RSR springs, or Swift springs. the RB ones are pretty soft. but thats my opinion. I'm running 10k and 8k coilovers.

Get the ebay MK1 coilovers... And fasten your nutbelts for the harshest ride you ever did see... I know a guy who put them on a 3rd Gen Eclipse, and the first bump he hit shot the rear strut right through the back glass...

Do you even know what you're doing?

Are you throwing on a "heavier RX-7"?
Or some other "Mazda"?

I personally like a stiff ride, and the MK1 coilovers are about as stiff as they come.
On the RX-7 they adjust +1" -1.5" in front and +1" -2.4" in back.

I am currently running -1.2" in front and -.9 in back.

Depending on the roads you drive - be careful what you wish for.

Yeah the RS*R's are pretty stiff. I believe around 335lb/in on the front and arond 245lbs/in on the rear, but they lower the car quite a bit and the poster was trying to get the least drop.

What do you consider "stiff"? You can buy springs that are as stiff as you want! Go out and google around a bit and you find sites like:

http://www.le-suspension.com/catalog...products_id=37

You specify the length, diameter and spring rate and they send them to you. You can get springs that will rattle the fillings out of your teeth (eg. 1300 lbs/in from the above site).

If you don't know what you want (and it doesn't sound like you do) then you need to start reading and asking simpler questions. For instance you need to at least understand that there is a big relationship between the spring rates and the valving (stiffness) on the shocks.

IIRC, the ITS guys are running about 450 lbs/in springs on the front and 250s (?) on the rear, but this varies by track. Just a reference point - this would probably be considered way too stiff for a road FC.

What are the stock spring rates of the 929 that you have?

sort of, but im starting to get confused. Im tryin to lower my 89 929 with FC parts, there is nothin availible for my 929. some tuners in Austrailia have done this already with their Luce's(929). They say FC coilovers with modified top hats will bolt right up & they have the coilovers wound up all the way which slams the ride & gives decent clearance. I don not know my OEM spring rates and cannot afford the coilovers I want for now, im looking for an easier temporay solution.

Another way they have done it is with using stock FC springs and struts. this Luce has this set up but the FC rear springs have been cut a 2" - http://img371.imageshack.us/img371/5600/lucefr0bv.jpg
this is the drop im looking for although i dont want the back as low.

when i was asking about stiff springs it was to compensate for the wieght, my 929 is ~3150lbs but am i wrong ?. with all this techinical talk about spring rates im getting lost. seein how the stock FC springs will lower the front 3.5" and the rear ~1" i wanted to know if a stiff set of FC lowerings springs would work to hold me over. does it look like a have to order sumthin from here - http://www.le-suspension.com/catalog...products_id=37 or can I get away with buying a new/used set of FC springs.

what do i need to do for a firm set up so my ride isnt bouncing off the pavement since it out wieghs the FC ?

if you can help me out or suggest somthin, much appriciated.

My turbo with me, my stuff, & a full tank weighs 3350.

Wow you almost got 1000lbs on my "TII"...

If you order a ground control kit they can get you nearly any spring rate you want, combined with height adjustability and the ability to choose spring lenths. They're $399US last time I checked.

This would be your best option in my oppinion.

i got the eibach prokit and its stiff as can be, but i also paired the up with tokicos all the way around, but 7 years down the road there still good and stiff

I dont know about the stiffest, but Im running the Tanabe gf210's which dropped my car 1.5" Heres a brief write up from Tanabe about them:

"The GF210 coil spring is geared towards maximum performance, without compromising daily driveability. A subtle drop provides an aggressive stance, while the higher spring rates (+20% - 30% over stock) provide excellent handling and vehicle stability characteristics. These springs provide a very noticeable gain in performance when installed.

The GF210 is well mated with a performance shock upgrade to extract the full potential of the coil spring, but will also work with factory equipment.

Each coil spring application is tested for fitment and optimal weight distribution for sportier handling."
