This Chevrolet Camaro SS was transformed into a Trans Am racer at SEMA with ZL1 1LE parts.The Chevrolet Camaro SS shown here is owned by Trans Am racer Todd Napieralski. It made its on-track debut earlier last year, but this road car-turned-race car is making its Sin City debut this week at the 2017 SEMA Show. By showcasing Napieralski"s race car, Chevrolet Performance is highlighting how components from the ZL1 1LE can transform a road-going SS into a competitive road race car.Todd Napieralski built his 2016 Chevrolet Camaro SS for the Trans Am TA4 class last year with help from Chevrolet Performance and Total Performance Racing. When this race car was being developed, the new 2018 ZL1 1LE hadn"t been introduced yet, so many of the components used on this Camaro SS race car were still in their preproduction stage. However, when the 1LE components were added to the Camaro SS, a world-class, production-based race car was born.Todd Napieralski"s Camaro SS Race CarTodd Napieralski 2016 Chevrolet Camaro SS race car began its life as a basic production model, with the 6.2L LT1 V8, the six-speed manual transmission, the Brembo performance brakes and a limited-slip differential. The drivetrain and braking system has remained unchanged, so Napieralski is competing with the same 455hp that comes in all new Camaro SS models, but a handful of ZL1 1LE components have made this car far more capable through the turns.First, the ZL1 1LE-Spec Multimatic DSSV Lowering and Handling Suspension Upgrade System (PN 84352121) replaces the standard suspension setup of the Camaro SS. This includes the Multimatic dampers at all four corners, new front and rear springs and the ZL1 front sway bar. This reduces the ride height by 10mm, but with a 245% increase in front spring stiffness, body roll is greatly reduced during periods of hard cornering.Next, Chevrolet Performance added the ZL1 1LE-Spec Suspension Upgrade System (PN 84352119). This package complements Multimatic DSSV Lowering and Handling Suspension Upgrade System with new front ride links, front handling links, rear upper and lower trailing links, rear knuckles, stiffer bushings and stiffer ball joints. These items stiffen up the chassis, leading to a 4% reduction in body roll compared to an SS with only the Multimatic Lowering and Handling package.Also, to improve rear suspension deflection levels, this Camaro SS race car is fitted with the ZL1-spec solid-mounted rear cradle mounts while the ZL1 rear spoiler helps reduce high speed lift.All of the components mentioned above are currently available for purchase from Chevrolet Performance.ZL1 Concept ComponentsTo complete the TA4 racing package, Todd Napieralski"s Camaro SS has a handful of concept parts from the Camaro ZL1 1LE. This includes the front fascia, the front fenders, the grille, the splitter, the dive planes and the heat extractor hood. These items don"t have a part number for direct fitment for the Camaro SS, but with a little fabrication work, all of these body bits will bolt up to any 6th gen car.When the whole package is assembled, this Camaro SS is a good enough race car to run at the front of the Trans Am TA4 class, so if you have a new LT1-powered Chevy muscle car and you like racing around turns following this build can convert your road-going car into a great road racer.Check out the video below for a look at this TA4 race car in action!
