SSR GTX04 wheels represent the pinnacle of SSR's lightweight engineering, crafted for drivers demanding maximum track response and minimal unsprung weight. Utilizing SSR’s proprietary FFT-R flow forming technology, this 1-piece monoblock wheel achieves an exceptionally thin inner rim profile with strength characteristics that rival forged construction. The design features ultra-slender spokes reinforced by single-step drop ribs and a thoroughly shaved center hub section to eliminate every excess gram of mass. The result is an ultra-responsive wheel that balances track-ready durability with a striking, minimalist motorsport aesthetic.
