When it comes to tuning Cadillacs, few rank higher than D3. It is, after all, the maker of the Le Monstre CTS-V, a car that we first saw at the 2011 SEMA Auto Show.

During this year’s SEMA show, D3 was back in full force again, presenting a new program for the Cadillac ATS, which includes a new body kit. This kit consists of a revised front bumper, side skirts with optional air foils, a new roof spoiler and a rear deck lid spoiler. All these parts were built by D3 itself and comes with OEM mounting points.

On top of all the aesthetic upgrades, D3 also treated the ATS with some mechanical upgrades, including installing an adjustable coil-over suspension system that can be lowered and the spring rate adjusted to the driver’s preference or track. The ATS’ suspension system also received an aftermarket lowering module that consists of two settings — "Street" or "Competition” — to help give it an extra edge in the twist. Finally, the standard air intake was also replaced by a genuine bolt-on D3 air-intake system.

These upgrades may look subtle now, but rest assured, D3 has something in store for all of us. It has built a reputation as one of the best Cadillac tuner in the world.

Pretty high expectations, sure, but D3 has earned it.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
