SSR Type C-RS (race spec)

this is the first picture of the NEW Speed Star Racing Type C-RS. It is the replacement for the SSR Competition.

(decals are optional and it will be available in the Subaru specific offsets of 51mm in 18" and 48mm in 17" )
In a specialized process perfected by Alumax, a leading aluminum manufacturer, uniquely structured alloy billets are heated to a semi-solid state (the consistency of soft butter) and molded in a specifically engineered forging press. The positive aspects of this process found applications in the aircraft and automotive sectors. Through an exclusive contract with Alumax, SSR conducted additional research and development and built their wheel manufacturing plant in Japan to produce alloy wheels using Semi-Solid Forging (SSF) technology. They further developed SSF technology, were granted a patent, and are the first and only SSF wheel manufacturer in the world today producing Semi-Solid Forged alloy wheels. This ultra high tech forging technology creates a very strong and lightweight wheel ideal for street or track.
In the 1980s, SSR researched and developed magnesium and titanium wheels in an effort to improve upon cast aluminum wheels that had reached their performance potential. SSR studied the feasibility of bringing magnesium and titanium wheels to the market and found several drawbacks, among them high cost and limited production capacity.
SSR knew, though, that higher quality, lower cost, well-designed wheels were what the customer wanted and in 1991 learned of the advanced technology of semi-solid forging (SSF). This technology was being used to produce parts for the aircraft industry where low weight and reliability are crucial. So, SSR obtained a license to use SSF technology from Alumax Laboratories and after one year of research and development built their now-patented wheel manufacturing plant in Nara, Japan.
Forging is the process of forcing a solid billet of aluminum alloy between forging dies under an extreme amount of pressure. This creates a finished product that is very dense, very strong. Less aluminum alloy is used to meet the strength requirements for the intended application resulting in very lightweight wheels. The costs of tooling, development, equipment, etc., limit the designs available and usually demand a high price in the aftermarket. Many racers have been willing to pay the premium price required to acquire strong wheels that are lightweight.
The casting process, pouring molten metal into a mold, offers a very reasonable production cost and is a good method for casting designs that are more visually oriented or when reducing weight is not a primary concern. The high heat used introduces impurities into the metals and results in a more brittle, branch-like microstructure that is more susceptible to breakage along its weak points. Cast wheels can be equal in strength to forged wheels but, in order to meet the demands for use on a vehicle, more alloy is used resulting in a heavier wheel. Cast wheels offer consumers the greatest variety of designs at the lowest price and are adequate for most street use applications.
Further research led scientists to develop a process whereby mechanically agitating (stirring/mixing) alloys during the solidification process changed the original microstructure of the alloy from a branch-like structure to a globule granular structure. Alumax then perfected the aluminum stirring process, Magneto-Hydro Dynamics (MHD), and created the basis of SSF technology which results in a pure cylindrical alloy billet consistently free of non-metals, gasses, oxides and other impurities. This MHD billet, when heated to a specific temperature, attains a semi-solid form (consistency of soft butter). After pressed into a mold at a very high rate, the shaped product retains the preferred globule granular microstructure. The end product is very dense and strong allowing the manufacturer to use less aluminum alloy and still meet the engineering criteria for the intended use.

Today, SSR is the only wheel manufacturer in the world to produce SSF aluminum wheels. SSR continues to research ways to further develop SSF, creating beautiful, lightweight and strong wheels that benefit the customer via function and beauty as well as enhanced performance�all at a lower cost than forging or casting.

The new finish makes me happy in the pants. Are they going to bring out a white or gold wheel?
| angryfist | 04-18-2006 09:52 AM |
are they changing the sizes? will there be a 17x8 5x100????
| TheWRX | 04-18-2006 09:52 AM |
How do these compare to the SSR Competitions? Lighter? Will the price be about the same? Availability? Do you already know what fitments will be available?
I read the text quickly, but it sounds like it's mainly explaining the semi-solid forging process, which I thought was already used for the Competitions. So I'd like to know what the differences are.

it is constructed using the SSF technology but it is a two piece welded wheel which does make it slightly heavier but approx. 20% stronger .... we did have some Comp-H wheels which utilized the same manufacturing process in the old style
| blue blurr | 04-18-2006 11:25 AM |
Are those wheels available yet? How about in a 17x8.5 platform?
| AtomicRacer | 04-18-2006 11:49 AM |
How about 17x9 or 17x9.5 for the '05 STi?

They were bought by somebody, and SSR Competitions (or at least the interesting sizes...) became available again just a couple of weeks ago.

what does the race spec stand for? I remember seeing regular type-c's too....so are these lighter or something? What about compared to the old comps?

Luke, SSR's website shows the C-RS in a 5x100 17x8.5 with +49 offset. Will you be selling this size?
God would I love this size but with a +35 offset for us SRT-4 guys!

Don't forget wheels are expendables, and they need to be replaced after a few years of AX'ing and/or tracking. Per The Tire Rack:
[url]http://www.tirerack.com/wheels/tech/techpage.jsp?techid=110[/url]
When you have to buy your first replacement SSR for almost $400 because of a fatigue crack, and you realize that you might have to spend about $1,200 in the near future, it's sobering!
[IMG]http://images6.fotki.com/v100/photos/4/43793/1098813/SSRScracked-vi.jpg[/IMG]
On the other hand, I LOVED my SSR's. I had them waiting in my living room before I even took delivery of my WRX! If I had the money, it's all I would run. But last year I needed four sets of wheels, Race R's, Practice R's, Practice high performance street/rain tires and everyday tires. Couldn't beat Rxxa wheels for that type of coverage. We just picked up a brand new set of 17 X 8.5 Slxxstxxxms today for $400 to mount our X tires on, because we couldn't find any 9" wheels at the last moment.
Maybe when I only need one set of wheels again I can buy another set of my favorite SSR's.

Honestly, all wheels should be checked for fatigues after serious autocross duty. Espeically, those with R-comps.
How about a 16X7 5x100 +50?
Make it 8lbs too ;)
