[TECH] FRC REFRESHER COURSE PART 1: WE PREPARE TO BREATHE NEW LIFE INTO A ’99 HARDTOP, WITH A LITTLE HELP FROM L5 MOTORSPORTS, FORGELINE, AND NITTO JAY HEATH WORDS | PHOTOS T he forward march of time is rarely kind to those it tramples underfoot, be they flesh or fiberglass. Along with the physical indignities of the aging process—the loss of outward luster, the deterioration of vital substructures, the dulling of one’s “performance edge”—there’s a far more insidious development to contend with: the inexorable retreat of relevance. Today’s hero is tomorrow’s has-been, and so it has been since time immemorial. The upside to dealing with impending senescence in the vehicular realm stems from the ease with which automobiles—and particularly Corvettes—yield themselves to the process of creative rejuvenation. Remove a fastener here, pop a retaining tab there, and pretty soon you’re well on your way to a fresh, new look—no pills, unguents, or liposuction cannulae required. With that in mind, we decided it might be instructive to take a not-quite-over-the-hill Corvette and treat it to an aesthetic overhaul 58 using an assortment of top-quality aftermarket parts. While our test subject—a ’99 fixed-roof coupe—was still in fine shape cosmetically and mechanically, this onetime performance flagship was starting to look a little dowdy next to newer offerings such as the Grand Sport, the Z06, and the ZR1. Let’s examine the items we selected to bring it up to date. LEWIS FIVE MOTORSPORTS BODY KIT We’d featured cars equipped with Lewis Five Motorsports hardware in the past, so we were aware of the company’s reputation for building Corvette body components that fit properly and look great. For our FRC, we drew liberally from L5’s parts arsenal, selecting a set of flared front fenders and rear quarter-panels, along with a quartet of matching fiberglass splash guards. (The latter items are also available in genuine carbon.) The fenders and quarters embolden the C5’s looks considerably, while avoiding the “tacked on” look that afflicts some competing offerings. Up front, the additional ¾-inch of width per side is subtle enough that it might be missed by a casual observer. There’s no overlooking the rear quarters, however, which swell the car by 2 inches per side—enough to swallow virtually any wheel/tire combo one might choose to fit (more on that in a moment). For the truly committed, L5 also offers a full wide-body kit that includes the aforementioned bits, along with new front/rear fascias and side rocker panels. We might take that step in the future, but for now, the fenders, quarters, and splash guards have our FRC on the path back to head-turner status. FORGELINE WHEELS In keeping with our focus on top-shelf quality, we chose a set of Forgeline’s new CF3C Concave forged wheels to fill out our FRC’s newly tumescent fenders. Like the company’s popular racing wheels, the five-spoke CF3C uses a three-piece design that’s held together with hidden stainless-steel ARP fasteners.

Though undeniably stylish, this 13-year-old C5 was beginning to show its age. 1 A set of Lewis Five Motorsports flared front fenders and rear quarter-panels (one of which is shown here, under the admiring gaze of car owner Greg Lovell) formed the centerpiece of our refurb project. These parts arrived at VETTE HQ carefully packaged and complete with installation instructions. 2 To complement the L5 fenders, we chose Forgeline’s new CF3C Concave wheels. Aside from their knockout styling, the CF3Cs feature forged 6061 T6 aluminum construction, heat-treated rim shells, stainless ARP fasteners, and plenty of clearance for aftermarket brake packages. Ours came in a standard brushed finish, but a wide variety of color options are available.

Fortunately, the L5 quarter-panels add a generous two inches of width to each side of the car, which should provide plenty of space. 4 5 As for the matter of wheel fitment, it’s clear from this angle that the L5 quarters offer sufficient clearance for our fatterthan-stock Forgelines. 6 In sizing our new rims, we thought it important to one-up the current crop of Corvette supercars. Fortunately, the L5 rear quarters provide sufficient clearance for wheels of up to 12 inches in width—the same as on a new ZR1. Since the CF3C’s modular nature makes it fully customizable, we were able to specify the precise size and offset required to occupy the available space and clear the C6 Z06 brake conversion that was recently installed on the car. You won’t get that from just any old molded-aluminum rim. (We did stop short of specifying race-style center locks, though Forgeline offers them as an option.) Factor in a wide range of available finishes, and the 3F3C is a superlative wheel choice for any style- and performance-conscious Corvette owner. 60 Laying one of the new quarters over its factory counterpart provides a preliminary view of the muscle-bound look to come. Though dramatic, the flared wheel opening is nicely integrated with the factory body line. Big, bold wheels demand big, bold rubber—in this case a Nitto Invo measuring a healthy 345/40ZR19 for the rear (right). At left is the previously installed 295/35ZR18, which looks positively puny by comparison. 7 The fronts got an upgrade as well, from a diminutive 255/40ZR17 (right) to a more suitable 275/35ZR18. Although it’s considered an ultra-high-performance tire, the Invo carries an impressive 260 treadwear rating. NITTO INVO TIRES With our Forgelines spec’d out, it was time to select a tire. Naturally, we elected to use the widest rubber our new wheels would accommodate, in this case a 275/35-18 up front and a steamroller-size 345/30ZR19 in the rear. (For comparison’s sake, the ZR1 wears 285/30ZR19s and 335/25ZR20s, respectively.) Nitto’s Invo is one of a handful of tires VETTE 12.09 VEMP-120900-C5.indd 60 5/16/12 5:09 PM [TECH] FRC REFRESHER COURSE 8 At 3⁄4-inch wider than stock, the L5 front fender (left) is notably subtler than the aggressively flared rear quarter. Since we were only adding 20mm of tire width at each front corner, this modest bulge was more than adequate. 9 10 11 The final pieces in our body-modding project, the front (shown) and rear splash guards complement the appearance of the other L5 parts and help keep road grime off the sides of the car. Since we weren’t bolting up the parts for this installment, Lovell simply held this one in place long enough for us to snap a photo. available in these sizes, and by far the most affordable. It’s said to offer an ideal balance of performance and ride comfort, which sounded like a perfect fit for our mostly street-driven FRC. It also has a wild-looking geometric tread pattern that’s sure to further enliven the car’s looks, especially from behind. 62 Since the factory fenders were already off of the car at the time of our photo shoot, Lovell laid one of the new L5 pieces in place to test its fit. While aftermarket body panels typically require extensive sanding and refitting prior to installation, the L5 fender dropped right on in out-of-the-box form. As you can see, those outsize rear tires aren’t just for show. With a modified LS3 engine reposing in the engine bay, our FRC should have no trouble pushing its natty new Nittos to their limits.
