Can anyone tell me how to determine if a set of wheels are original Porsche Speedline wheels?

 

it says so on the wheel.

 

X50type is correct "SPEEDLINE for PORSCHE" or some derivation of that phrase. If you search in this forum asking: "SPEEDLINE wheels" you will find posts with photos of the wheels in question.

 

Here yer go...... Speedline for Porsche [they are made in Italy by Alessio].

 

^^^ Sometimes that logo is missing if the wheels have been polished for some reason. You should post pictures of the wheels in question if you can, there are a few people here that can tell you if they're authentic or not just by looking at the bolt heads ...

 

I am attaching a picture. I can read Techart Speedline on one of the rims nothing readable on the other three.

 

Those are Techart Daytonas by Speedline. I could be wrong but these arent "Speedline for Porsche"

 

^^^ correct, the difference being the latter are 'commissioned' by Porsche for a specific model car as a factory offered wheel. i.e. 964 3.6 Turbo or 993 RS

 

My understanding is that Alessio Speedline for Porsche wheels were never fitted as OE from Stuttgart and the wheels shown are not Speedline for Porsche wheels..

Others chime in.

 

that's correct, the Speedline Alessio have a center similar to Speedline for Porsche, the barrels appear to be the same design but have differing widths. Hardware may or may not be different the oe Speedline for Porsche have a green tint to them, the Alissios I had had been rebuilt and the hardware was not at all the same. Weights were comaparable

Alissio 10


Speedline for Porsche 10

 

Can the RS wheels be converted to 11's in the rear?
Sonny1.

 

It's not just about the 'Speedline for Porsche' etching - you can pay to have that stenciled / etched on any set of wheels you want - you can tell a real SL for Porsche wheel by the bolt heads and the Porsche part # on the rear side of the spokes....

 

That's true too

Can anyone suggest the best way to sell these rims and how to determine a fair market value?

 

I will have my set for sale very soon. I purchased them thru sun coast and they came directly from Germany. I have original boxes and packing. I had them on my. 993 cab I sold this past fall. They are in mint condition. I believe I paid with tax delivery etc close to 5k 2-3 yrs ago but they were almost impossible to get your hands on an original set. I think they are 6 k plus now thru sun coast.
