We’ve been working with Top Secret for 8 years now and one thing remains consistent…they’re true to their name. The origins of the Top Secret name go back to the days of Nagata-san working at TRUST and doing his own side projects which were always Top Secret. Nobody knew what the man was doing but surely he was busy building greatness. Of course the name stuck with him long after his days at TRUST.

The years go by, but some things stay the same. Being Top Secret USA you’d think that we would know what project cars the Japanese office is building. Yet oftentimes we have no clue what the latest project car is. This is one of those examples. The platform of choice, a recent model GS460. The car choice actually does not surprise me after riding with Smoky and Shibuki-san in their Lexus daily drivers (in the past they’ve had twin turbo GS and LS’s for commuting).

The Top Secret Lexus GS460 happened to be uncovered by Option Magazine. We’re grateful for this because there are literally dozens of complete custom cars by Top Secret that never have been seen (did you see our earlier sneak shots of a never again seen matte black TS widebody Porsche 996 Turbo).

This GS features some pretty impressive modifications…

How about R35 GT-R brakes front and rear!? It is not too often we see those outside of the GT-R and especially not on a Toyota/Lexus!

The car is running some very expensive and quality coilovers from Toms and rocks the always classy 20″ BBS LM wheels. The exterior is subtle and modded with Lexon parts.

The engine is tuned to 480ps with the use of a HKS GT3037 turbine and a F-Con tune.

With a number of other one-off modifications ranging from the exhaust to the brake conversion, this car ended up costing about $170,000 USD.

Innovative. High Performance. High Quality. Exclusive. Expensive.
That’s pretty much the definition of Top Secret and proven here once again.
