Lexus is gearing up for a big showing at SEMA. In addition to bringing four tuned IS Fs, including one from our friends at 0-60 magazine and another from Fox Marketing/Artisan Performance, long-time Toyota collaborator, Five Axis, will be debuting a heavily reworked GS 460 in Vegas.

Also on hand will be IS Fs from Import Tuner/Tein and MotorworldHype, along with an ICON-designed LX 570 sporting serious off-road upgrades, an IS 350 kitted out with F-Sport accessories and a prototype body kit, plus the 2009 IS F with a handful of upgrades and a new interior color.

Toyota gave a sneak peak of its two tuned Venzas ahead of their unveiling at SEMA, and the first, designed and executed by Five Axis, is an attempt to portrait the jacked-up wagon as the go-to vehicle for active lifestyle types.

The Venza AS V (Active Sports Versatility) features a custom body kit, Five Axis-designed AD R6:F_SPEC 20×10.5-inch deep dish wheels wrapped in Yokohama Advan ST tires (305/45s all around), TRD big brakes with six-piston calipers gripping 15-inch discs up front and four-piston calipers clamping 13.6-inch rotors in the rear, along with a custom rear cargo unit and a Magna Car Top cargo lifter mounted on the rear bumper.

Toyota’s SEMAfied Venzas won’t stop, even if we ask nicely. The second modified don’t-call-it-a-Camry wagon comes courtesy of Street Image, which will bring the SportLux Venza “performance show car” to SEMA. A contradiction in terms if we’ve ever heard it.

According to Toyota PR, the SportLux is a model that could be offered as a factory tuner, complete with six-piece body kit, spoiler, custom grille and, of course, a hood scoop.

Thankfully, Street Image’s blood, sweat and tears didn’t stop with the body, so a TRD supercharger has been fitted to the engine (although no power figures were divulged), sending the additional grunt to four, 24-inch Chrome Cognac No 20 wheels (seriously), suspended by a set of custom coilovers. The same brakes fitted to the Five Axis vehicle appear on the SportLux, and in keeping with the “Lux” part of its name, black suede covers the roof, sunvisors, pillars and trunk, along with a black and burgundy leather interior, accent lighting and color matched trim. An Eclipse AVN6620 sound system with a 7-inch TFT display churns out 2,500 watts of only the finest Michael Bolton.

Everything is in line to be a convergence device, and now the boring rear view mirror has stepped under the lights to get stuffed with extra equipment. The Azentek SmartMirror has a four-inch touchscreen on the right for a 2D and 3D text-to-speech GPS display. It’s also offers Bluetooth connectivity, a call log, and caller ID. It has two video inputs, one that can be used for a rear view camera, and an SD card slot in case you want to record… well, whatever you might want to record with your rear view mirror.

The only thing missing from the mirror is availability — it’s been so popular that Azentek can’t supply enough of them. The company says that will change later this year when you’ll be able to get it at major retailers. The other potential hitch: it’ll cost you $800 to do what your phone, TomTom, and regular mirror already do.

About a decade ago, Roock Racing was one of the most dominant GT racing teams at Le Mans and a short time later in the ALMS with their Porsche GT2 race cars. Since then they have focused their attention on tuning street Porsches, the latest of which is the RST 600 LM that commemorates their victory in the GT2 class at the 1996 24 Hours of Le Mans. The package includes upgraded turbochargers, a titanium exhaust system, and an upgraded ECU good for just over 600 horsepower and 611 lb-ft torque. Performance numbers are a claimed 3.1 second sprint to 60 mph and a top end of 211 mph. Roock also adds a carbon fiber clutch, fully tuned suspension, and massive 380mm drilled and vented brakes. Inside, the RST 600 LM gets carbon fiber trim, oil and temperature gauges, and custom seats with four point harnesses. Finally, subtle exterior modifications are added including a new front splitter, rear diffuser, rear spoiler, and lightweight aluminum racing wheels.

If Drake, the ur-vampire from Blade Trinity, were a car, this is the car he would be. Starting with a CL600, tuning firm Kicherer didn’t waste time throwing pieces at the car’s already aggressive styling. Instead, Kicherer attacked the CL’s jugular: sloppy performance due to the car’s portliness.

The biturbo V12 gets 53 extra horses to corral 570 in total, torque gets smacked up to 664 lb-ft., the engine gets a new transmission control module to better deal with the extra juice, and out back, the rear axle gets a locking rear differential. The car is lowered an inch, and firmer springs help keep things settled when it’s go time. Will all this turn the car into a cheetah? Probably not, but with the carbon goodies added throughout and the 20-inch Kircherer RS-1 wheels, it will look mighty good doing whatever it does.

Every time we see a Flex on the road, it looks cartoonish to us – those two massive rectangles sitting on cute little wheels. We wouldn’t be surprised if, a la CARS, a Flex started talking to us. The “ReFlex” above, designed by Sean Smith of SS Designs and being prepared by CGS Motorsports for this year’s SEMA Show in Las Vegas, looks like it could have something interesting to say. Who knew that a minimal body kit, a drop, and a set of 22s could give the Flex that personality it’s been missing. The custom DuPont-painted CUV is also getting a suede interior, a Kicker sound system, and even new door solenoids from SPAL. We’ll take it, or at least a ride in it.

There are six modded Genesis’ planned for SEMA: three coupes, three sedans. The coupes have been worked over by Street Concepts, HKS, and Rhys Millen. A rendering of the first tricked-out Genesis sedan from RKSport has rumbled onto the page, and it looks less like competition for the 5 Series than it does a challenger to the Death Star. The Platinum Silver sedan will wear carbon fiber accessories and a couple of spoilers as it hunkers on its oversized TSW wheels.

RKSport’s take on this car is to raise the performance stakes, and it’s going to have Hyundai’s help doing it. The whipped cream on the sunday will be a K&N air intake, Magnaflow exhaust, Eibach springs, Baer brakes, and a body kit. The sunday itself consists of performance upgrades that Hyundai is giving to the car’s Tau V8 engine. The Korean automaker is hush-hush on those changes, but they’re probably good for a bump in the numbers in all the right places. And since you can’t drive the cars at SEMA, they’ll probably look and sound pretty good, too.
