opinions on springs.
The previous owner of my 91, being a complete retard, decided cutting the stock springs is a much better idea than just putting upgraded springs in the car. I was hoping to get some opinions from other people on what they are running on their cars, I was considering either going to Tanabe, Racing Beat, Tein, or H&R. If anyone would like to tell me their experience and how the handling characteristics were I would much appreciate it.

Without a shock upgrade at the same time I'd find some stock springs... the stock (non-R/LE Bilstein) shocks won't take much more than stock spring rates and work properly.
I'd find stockers in a wrecking yard and start saving the ~$2k that real suspension costs... |
well its got a newer set of KYB GR2 shocks already. I'm more worried about the fact that cut springs, aside from being majorly ghetto, are soooo f-ing unsafe. Im not looking for super high performance, since the car is my daily, and will only see any aggressive driving one or two saturdays a month. Main plan for the car's setup will be springs on adjustable shocks, going full poly bushing set, and adjustable endlinks for the sways, possibly upgrade the bars if i want it any stiffer.
Just really want opinions on the springs available for the car. Im really considering the Tanabe gf210 springs. |
Well, GR2s aren't that great for anything but DDing...tending to blow the hell up when slammed.
Go post a wtb for the 'old version' FM springs. Decent rates, good lowering, should be able to get a set used for like 75-125. |

I didn't buy anything, other than an abused car. I wouldnt put anything KYB makes by choice on any car. The car already had the gr2 shocks with the cut springs. I plan on buying tokicos or koni's when i have the free money to put into it, i wouldnt be thinking about the springs if they werent hacked like they are, there are plenty of other things that need money put into them for now, like i may have a coolant leak at the "cursed plug" to deal with unless im lucky and i wasnt able to get a clamp tight enough earlier today.
Thanks for the advice, i really appreciate it. |
KYBs were my first setup (found them half-priced new in box), and as much as I hated them they can be alright* for the street.
They absolutely SUCK with the eBay coilovers and will probably blow. They are comfy and handle nicely with stock springs, but are at stock height. The Tein S-Tech springs were the best balance. These have good, linear rates (unlike many "drop" springs), a good drop, and a good F/R ratio. They are also cheap used ~$100-125. I used a rear spacer on mine to get a little more travel and give it a little rake. Only thing I did wrong was ordering the wrong FCM bumpstops (54mm) when I should have order the 36mm or whatever the smallest they recommend for the AGX. I sold them last summer, but if I had put in the right bumpstops I may have really enjoyed that setup. It wasn't exactly what I was looking for anyhow, but was the last setup my wife didn't complain about. It was certainly better than stock...and honestly the nicest stance I got out of anything until I had adjustable sleeves. Surefooted, predictable, just a little bouncy at times, but not as bad as Konis w 450/300 spring rates. Take care. |
I dunno why you guys would water your time on springs like: Tanabe, Racing Beat, Tein, or H&R. If you're actually looking for extra performance and a mild drop, get the FM springs.

I agree with Brianeack.
I know you probably want to get rid of the current "setup" as quick as possible, but save and go with FM springs. I have no track experience with them, but on the street they are amazing. |

The spring rates I finally settled at (and ride height for that matter) are almost identical to the FM springs. I was never lucky enough to find a cheap set though. Good luck. Spend the money up front on suspension = less grief later. |
Why waste your time on those, do a diy coilover///thread
|
so, while i was putting my 16's on today my buddy was messing around and wiped down my springs with a rag, turns out they are eibachs. Looked up the spring rates on these pieces o' junk. 140 Linear in the front and 70/120 progressive in the rear. I'd feel better if they were cut springs. Thinking I'm gonna step it up next month, since i've gotta dump money into the charging system that just crapped out. Definitely gonna spend some time on research and find what will be best for my DDing the car and hitting the twisties every other weekend.

I'm always amazed when I ride in AbeFMs car how reasonably comfortable it is, given that he's running some insanely high spring rates (I wanna say 700/500, or something in that general neighborhood) with Koni Sports. |
I agree with the FM's being a bit soft. I still like my R-Bilstein/FM setup, but I would like 100lb/in more per spring. I actually noticed my ride got smoother with the FM springs over the stock springs. My theory is that it has something to do with the stiffer springs doing more of the work, taking some of the stress off of the fairly aggressively valved Bilstein shocks. In the future when the car gets the LS1, it will get all new suspension again, something quite a bit stiffer. ~450f/325r would be ideal for me I think.

ok, im sure this is one of the most retarded sounding posts thats on this forum but, where are you guys going to get springs with these more aggressive rates? I'm used to dealing in cars that you go straight for typical off the shelf parts with suspension, like going to Tein or Tanabe.
Thanks, and sorry for being such a noob. |

Here's an example of such a device with a spring mounted on it, made by Ground Control, which is a reputable maker of such things, and courtesy of Good-Win-Racing. http://www.good-win-racing.com/miata...undcontrol.jpg And here's a similar setup mounted on a shock, courtsey of FatCat Motorsports. This is FCM's own design: http://fatcatmotorsports.com/igaller...Revalve_PM.JPG Many, many Chinese knockoffs also exist, some of which are ok and some of which aren't. Once you've got these mounts, you are able to run standard 2.5" coil springs, which are probably the single most common size in all of auto racing. Thus, you can buy springs in virtually any length and rate from just about anywhere. Summit, Jegs, Pegasus, etc. FWIW, Tein uses these standard-sized springs. The only difference is that theirs are green and cost more. |
I agree with you guys about the FM springs. ^ Good info there, helped me too.

I'm running 550/300 QA1 springs on my koni sports (NA) and I either need to re-valve the shocks or go to like a 400/275 combo. It's damn harsh driving around (the rear literally bounces up on bumps), however, the performance is wonderful. |
Tire Rack has the Koni coilover kit for $936 for a 1997 Miata. Pretty darn good price.
It doesn't look like the Koni Sport shocks, so I'm not sure how good the progressive springs are, I'm sure it's fantastic for daily driving...but autox and track, is it a decent bang-for-the buck? Dunno. +1 for the Ground Controls. I'm rocking 550 or (500lb) front, and 350 rear. |

I'm comparing them to the price point and ride height of the tech.S and Racing Beat and other weak ass drop-in springs. If you're simply looking for a spring to throw over your shocks and lower the car and get better performance, at that price point they'll be the best before going to a sleeved spring.
Just saying that for an extra $150 you can upgrade to full adjustability and get any spring rate imaginable, IF your shocks are man enough to handle it.
