2019 Audi RS3 LMS-Inspired SEMA '22 Time Attack Build

Zach and Shawn at SEMA 22

Owner: Zachary Cramer

Builder: Shawn Bassett / Attacking the Clock Racing

Distinction: SEMA '22 *TOP 40* Battle of the Builders 


Starting out as a stock Audi RS3 street car, this wide body RS3 build has come a long way! This build pays homage to the 1989 Audi 90 GTO with the deep concave aero discs and 2000’s / current DTM aero influence, plus we’ve mixed in a little RS3 LMS and big time attack aero!

We collaborated with Designer Jon Sibal to design an insane render that is nearly indistinguishable from the car as it sits today!

The car is a full carbon fiber car with an added 10" in width over stock! Tons of aero added to keep planted: APR Performance GT-1000 Wing and Hood Vents, Custom Carbon Fiber Fender Vents, Canards, and Headlight Covers.

Toyo Tires R888R DOT tires wrapped around BC Forged Custom Wheels

For power, we have a 1000HP IROZ motor with an AWD DCT Transmission. Suspension set up has tubular subframes and all-billet suspension arms.

Inside the car, we’ve made her race-ready by adding a full FIA-spec cage, a fully-integrated fire suppression system, OMP Race Seats and Harnesses and finished with a super clean interior.
