Great find Stefan!! Just to be double sure... those prices are in AU Dollars, and are for a pair, correct? If that is Australian Dollars, then at todays exchange rate, that works out to $69.73us a pair! Great price!! WHat kind of quality are these springs
Hi guys. This is Josh McClain, owner of 185 Performance. We are located just to the southwest of Denver, Colorado.
Thanks to Stefan for inviting me over here.
Anyway, we're hardcore Toyota lovers. I personally own a 77 RA29, 88 ST162, another 88 ST162, an 88 ST165, a 92 ST185, and a 97 VZN170.
Besides the typical aftermarket parts (GReddy, HKS, etc.), we import various goodies from Australia. The three primary manufacturers being Dobinsons, SuperPro, and Whiteline.
Since this is a Dobinsons thread, I'll just briefly mention the Whiteline section of our website:
http://www.185performance.com/cgi-bin/185p/whiteline.html
And here are the Supra pages from the SuperPro polyurethane catalog:
http://www.185performance.com/superpro/superpro-supra.pdf
Now, Dobinsons Springs. Dobinsons has been around for a long time (1953), and they're not too well known in the USA yet. We started importing their springs because their catalog covers most every car we're interested in! (All the way back to the TA20 Celica.)
Dobinsons coil springs, on average, are 25% stiffer than stock, and come in stock height and lowered versions. The lowering springs will drop your car between 20-30mm (depending how much your car has sagged due to age). Some are linear rate, some are progressive rate (the part number for progressive rate springs end in a "V").
The Dobinsons coil spring catalog is here:
http://www.185performance.com/dobinsons/Coil_Spring_Catalogue.pdf
Just go to www.185performance.com and plug the part number into the search box (for Dobinsons, Whiteline, SuperPro, etc.), and you'll get a price. As someone mentioned above, since we are in the USA, everything is shown in US Dollars.
We place orders Dobinsons parts once a week (Monday).
If anyone has any questions, please don't hesitate to ask.
Cheers,
Josh

Josh - progressive springs?
Hi, Josh,
What's the main difference between the progressive and standard springs?
Will the progressive give you better performance over poor pavement (I live in New Mexico) but still not make you lose the ice out of your drink in the corners?
I tried to plug in the part number but I didn't get any hits...

Re: Josh - progressive springs?
> What's the main difference between the progressive and standard springs?
A linear rate spring has the same stiffness throughout its compression. A progressive one is wound in such a way that as it gets compressed more, the spring rate (stiffening) goes up. This is a good compromise for the cornering demons out there who want a really stiff spring but need a softer suspension during regular street driving.

See above.

Thank you.
> I have Dobi springs on my car. Are Dobinsons springs related? Just wondering...
I honestly have no idea. I've never heard anyone refer to "Dobinsons" as "Dobi", so I have to assume they are different companies. Do you have a web address for Dobi?

Right Razor... dobi is no more. They were located in Brea, CA but closed up around '97 or so when the rice hit the fan. They sold some really cool stuff for old Toyotas, RX-7s, Zs, and a few other specialty vehicles.
Dobinson springs are the real deal and so is Josh/185 Perf. I recently helped a bud install Dobinsons springs and a slew of other suspension goodies acquired from Josh onto an MX70 Cressida. We chose a not-so-common type setup and it turned out awesome... in fact I'm sorry I sold the car. Well, actually, it just makes me want a Cressida wagon even more :]
Also, I believe that the Whiteline springs for our app are actually rebadged Dobinsons, but I'll let Josh elaborate or correct me on this.

Jimi B

Ahh -- too kind. Thank you.

Actually, Whiteline has its own springs -- they are not rebadged Dobinsons.

Yes; however, no "kits" per se, but here is the info you need:

Spring Rates
I asked Dobinsons for the spring rates on all of these sets. Here you go, guys...
C59-054V unsure about initial rate, progressing up to 35.6 N/mm (progressive rate, due to the "V")
C59-054 35.6 N/mm
C59-056 35.6 N/mm
C59-101 38.07 N/mm
C59-103 40.83 N/mm
C59-068 28.23 N/mm
C59-070 28.29 N/mm
C59-059 40.63 N/mm
C59-061 40.63 N/mm

Re: Spring Rates
It is great to know that we have alternatives when it comes to suspension components for our cars.
With regards to the above spring rates:
Do those numbers mean that the rates for the rears are stiffer than the fronts?
Are the front spring rates for the MA61 (C59-068/070) softer than the front spring rates for the RA60 (C59-054/056)?
Best Regards,
Carlos

Re: Spring Rates
> Do those numbers mean that the rates for the rears are stiffer than the fronts?
In almost every case, yes. In determining a spring rate for a given vehicle, one must consider where on the control arm (length from inner joint) the spring is mounted, and the angle of inclination (normally, the spring leans in). The necessary spring rate is then dependent on these numbers. Let's say you wanted a spring rate of "x" for a given corner; the angle of inclination and the position on the control arm may ultimately dictate a rate of x * 1.4.
> Are the front spring rates for the MA61 (C59-068/070) softer than the front spring rates for the RA60 (C59-054/056)?
It would appear so.
If someone has cars with stock [non-sagging] springs that can be measured, I'll go through all the math to help explain the chosen spring rates.
And sorry for the delay on this reply -- I was at Pikes Peak for the race.
Cheers,
Josh

Hi Josh,
Thank you for clearing those questions up for me.
I may give you a call about some springs for my Supra.
Were you racing up Pikes Peak? Hope you did well.

You're welcome.

I wish. I just spectated, hung out with my coilover supplier, DMS (www.dmsamericas.com), and complained about there being no Toyotas racing. One of these years I'll have to build up my st165 for the race.
