Stumbled upon this thread and thought I would correct some information. Forgestar wheels, even though their name has the word forge in it doesnt mean they are forged.
Forgestar calls their process "Rotary Forged Flowforming" which is similar I guess you can say to Enkei / Gramlights Flowform process.
Link to their website on the process
Taken directly from their site :
" This specialized process begins with a low pressure type of
casting and uses a special machine that spins the
initial casting, heats the outer portion of the
casting and then uses steel rollers pressed against the rim area to pull the rim to its final width and shape. The combination of the heat, pressure and spinning create a rim area with the
strength similar to a forged wheel. During Flow Forming,
the pressure applied to the cast rim actually changes its mechanical properties, so its strength and impact values become
similar to those of a forged rim. That translates to up to 15% less weight when compared to a standard cast wheel. The resulting grain structure within the alloy of the wheel is linear, flowing in a single direction. "
I am not saying Forgestar doesnt make nice looking wheels, but they are nowhere close in strength as a truly mold-form forged wheel like a Rays Volk Racing TE37SL.
