Engineering-led parts for the cars I own, build, and love.
I build small-batch motorsports parts for the Japanese performance platforms I own, understand, and care about, starting with the cars that have shaped my life as an enthusiast, engineer, and competitor.

In Development
I use my own cars as development platforms, which keeps product ideas grounded in real fitment, real packaging, and real enthusiast needs.
IS300 Front Upper Control Arms
My current development focus is a front upper control arm design for the first-generation Lexus IS300. The project is in prototype development with attention on geometry, serviceability, and real-world fitment validation.
Prototype photos and fitment updates will be shared as the design moves forward.
Coming Soon
The FL5 Civic Type R is the next major Sianar Motorsports development platform.

Product ideas are being evaluated around the car as I spend more time with it, learn the platform, and identify opportunities for thoughtful, functional parts.
Why I Build
Sianar Motorsports is a personal side project built around the cars and communities that have shaped most of my life. I have been involved with Japanese performance cars since 2002, with roots in Hondas, Nissans, and motorsports.
My background includes engineering work in the automotive aftermarket, suspension design for street and competition drift and road racing cars, and hands-on experience competing in multiple forms of racing. I build parts for platforms I personally own, understand, and care about.
