guys due to all this misinformed technical details going around about the whole TE37 vs. TE37SL, I just went straight to the source, Rays Engineering to get you the final say on their products.

Pinhead, and to the m3post community members...

This is straight from RAYS in an email I sent them regarding this post –

Your info is incorrect.

The TE37 and the TE37 SL are both 100% Mold forged. There are NO Volk Racing wheels that are Cast, Flow Formed etc..

The difference is that the TE37 SL utilizes an updated mold that has some areas thicker for strength and some areas that are CNC’d to reduce weight where it isn’t necessary. The TE37, although still industry leading – is an old wheel, therefore we found many areas to improve. The lower price was initially brought about to make up for the difference with exchange rates for the overseas market as a limited model, but due to the popularity (and the price) the SL’s and subsequent versions have took over most of the sales. Updated TE37 is in the works.

Your response to how the TE37 is made is also incorrect as well.

RAYS utilizes 8000 ton and 10,000 ton press that press the wheel individually with 8000 tons of pressure (larger diameter and more complicated shapes use 10K press) – In the TE37’s 18inch case – there will be 2 strikes with an 8000 ton press to make the basic spoke shape. Then RAYS utilizes a RAYS only RM3000 process where utilizing a mold from the top and bottom – the shape is forged together while in a spinning process to extrude the rim section – hence a 3D forging which allows for best control of grain flow.

W12x – if you have any questions regarding wheel manufacturing please contact the manufacturer and we’ll be more than happy to explain.
