Ikeya Formula tie rod ends and similar designs

[TurDz]

I was wondering if anyone had Ikeya Formula tie rod ends. Their (patented) shank design as seen below:

I wanted to know why you guys think they designed them with that tapered section.

Additionally, if anyone can find or take some high resolution pictures of these, I would be very appreciative.

Thanks.

SPL's design is similar, as well as Kazama's.
They're not exact, but a similar heim joint design.

They're not very similar to kazama or spl. They're more like peak performance style. They're relatively cheap if I remember correctly. Or affordable, I guess is a better word.

I'm more interested on why you guys think they designed them that way, and if anyone has bigger pics of them. Thanks

how about sending them an e-mail directly to ask why

Ikeya Formula is like triple the price of what regular high performance suspension components cost.
