The product that we fell in love with, however, is the optional PS-5001 paddle shifter. For an extra $425, it turns your GSM-shifted street machine into a juggernaut, capable of commanding any gear instantly with a satisfying tug on its two black-anodized brushed aluminum paddles. (The left paddle is for downshifts, the right side is for upshifts.) The whole GSM-5000/PS-5001 enchilada reeks of covert military black-ops hardware; a bombproof control box with mil-spec connectors, strain-relief harnesses, weatherproof housings, precision CNC machining, non-reflective black anodizing, and easy-to-read LED displays not only look the part, they are the real thing. PCS designs and builds powertrain solutions under contract for the U.S. military, so real lives are at stake. This stuff has to work perfectly all the time, every time, and under every conceivable condition, or the wrong people can die. Oh yeah, and it's made in America. As far as we're concerned, every GSM-5000–equipped car deserves to have the PS-5001 paddle shifter option—it's just that fun.

In the months since we've installed ours, we've had the pleasure of pounding on the PCS system in a multitude of situations. I've got a C6 Corvette daily driver with the A6 trans and paddle shifters, and it has proven to be nowhere near as fun as the Laguna with the PCS paddle shifter. The 'Guna has another 220-plus horsepower over the Vette, but it's half a ton heavier, so its solid-roller small-block really needs the rpm to keep it in its happy place. In the past, we almost never experienced the sweet song of the .680-inch lift cam at concert volume. We had tinkered with the throttle-valve (TV) cable length and governor weights in the trans, but the bulletproof 700-R4 wasn't letting us play. Now that we can hold each gear to redline, we are blown away by all the fun we've been missing. Having the power on tap with a light squeeze of the hand is only part of it; hearing the redline snarl of the solid-roller small-block and Flowmaster 40s ricochet off concrete makes you feel like you're at Daytona or Talladega. Long, lurid burnouts without the trans burping out a Barney Fife upshift is icing on the cake.

So now you're wondering what's involved with putting one of these PCS paddle systems on your car. We invited Jay Rohrback of PCS to come out to the PHR tech center in Irvine, California, to show us what's involved. In our two-day wrenching mission, we captured it all in pics and video (you can check out for the 23-minute video), and we deem this an easy weekend driveway/garage bolt-in. We still haven't figured out exactly where to put the push-button pad, but we're kind of glad we didn't mount it right away because we want to live with it for a while first. Otherwise, this was straightforward wrenching. The instructions were clear (even though we had the inventors in our midst!), and everything was included, with the exception of a five-bolt steering wheel. (We ordered a 14-inch Grant GT wheel from Summit for $95.) The hardest part was running through the shift detent calibration, whereby you move the cable in and out with the "+/-" buttons on the push-button controller.

We're still awestruck that such a simple mod like a paddle shifter can make such a huge difference in the personality of a car. We're finding new ways to terrorize import drivers every day, and it's only by the grace of God we haven't been locked up. Get this paddle shifter, and you too will be looking for excuses to drive your hot rod everywhere. Moreover, we are prepared for it to unlock a new world of fun on the dragstrip, autocross, and road course when the opportunity knocks. The sooner, the better!
