A textbook example of the type of street cars you would find in Japan, Signal's Si punches the point across the Pacific.

This tangerine dream was the only Si out of the bunch to be built overseas. The car was shipped out to Osaka-based Signal Auto. Walking the tightrope of being either a streetcar vs. being a racecar is a daunting task. Signal pulled through with flying colors. The entire interior remains intact, and the custom widebody is so smooth & subtle, you can only tell from about five feet away. The car features a fully built K20, complete with a Trust TD06 L2 (20G) turbo, Tanabe Sustec Pro S-S coilovers and Volk SF-Challenge wheels wrapped with BFGoodrich g-Force T/A KD rubber. Signal opted to use 18x9's in the front and 18x8's in the rear.
