In part one of this two-part series, we look at interior modifications that improve the driver's performance and comfort.
So you've got your engine putting out the power, your suspension/wheels/tires are dialed in, brakes are beefed up and the body is done. Now it's time to turn your attention to the interior. With your ride's notably increased performance and handling capabilities come increased responsibilities for the interior. Specifically, keeping the driver securely in place during high-performance driving, providing him with an effective interface between the car and himself, and monitoring additional engine parameters, such as turbo boost.
In the first installment of this two-part series we address seats and steering wheels, two important components that can optimize the performance of the most critical component in the car – the driver.
Get a hold of yourself
Now that you've got the more capable suspension and stickier tires, you don't want to be sliding around in your seat while you're unraveling your favorite twisty mountain road or taking part in a high-performance driving event, such as an autocross or a track day. A well-bolstered sport seat is key to holding your butt (and the rest of your body) securely in place while you're enjoying your car's athletic handling. It's also a safety benefit, as you can better concentrate on the task at hand rather than having the steering wheel double as a grab handle as you try to prevent yourself from hip-checking the center console.
There are basically two types of performance seats, fixed back and reclining back. As the name implies, the fixed back seats are non-adjustable for recline. Advantages of a fixed-back seat include an abundance of lateral support and excellent compatibility with five- and even six-point racing harnesses. Fixed seats tend to be the choice of those whose car sees more racing duty than daily driver duty. Going with a reclining seat means you'll enjoy greater comfort, much easier ingress and egress, easier rear seat access and considerably greater compatibility with stock seat belts. Reclining sport seats provide a nice balance between high-performance driving support and daily driver livability. Recaro fixed back seat in a Porsche 911
There are a number of companies to choose from when selecting a sport seat, such as Corbeau, Procar, Recaro and Sparco. Recaro seats in particular have been found as either standard or optional equipment in various high-performance cars over the years, ranging from Fords to Mitsubishis to Porsches. That said, all these manufacturers offer well built, comfortable and supportive seats for a wide array of applications.
Steering you right
Unless your car is over 20 years old, it probably has an airbag-equipped steering wheel. As such, you may choose to keep it in place for the added safety factor. That said, some enthusiasts prefer to swap out that original equipment wheel for an aftermarket unit. A few reasons are that a smaller than stock diameter wheel provides slightly quicker turning, a rim wrapped in leather, suede or Alcantara (artificial but very convincing suede) gives a more tactile grip, and an aftermarket wheel usually looks at least ten times better than that typically blocky stock affair.

Just as with the wheels you wrap your tires around, the wheel you wrap your hands around comes in a dizzying array of brands and styles. Check out the sites of Momo, Grant and Nardi and you'll see what we mean. We prefer the classic three-spoke racing style with a traditional, non-sculpted rim, but your personal preference may dictate otherwise. Given the rather large amount of time you spend using the steering wheel, the importance of selecting one with the right overall diameter, ideal rim thickness and preferred grip cannot be overstated. As such, we suggest going "hands-on" and checking out the wheel (or wheels) you're interested in at the store in addition to researching them out on-line. As they say in the car selling business, "the feel of the wheel can seal the deal."
