CHEVROLET CAMARO SS TRANS AM TA4-SPEC RACE CAR

TODD NAPIERALSKI’S CAMARO RUNS AT THE FRONT OF THE FIELD WITH CHEVROLET PERFORMANCE ZL1 1LE PARTS

2017-10-30

For more than 50 years, SCCA Trans Am has pitted production-based race cars in one of motorsports’ most exciting and enduring road-racing series. One of the standout competitors today is Todd Napieralski, who drives this Camaro SS racecar in the Trans Am TA4 class. He drove it to a second-place finish at Road America last year, in its first outing.

Part of Napieralski’s competitive edge with the Camaro comes from ZL1 1LE chassis and suspension components that enhance the car’s road-holding and handling capabilities. When built last year with the cooperation of Chevrolet Performance and Total Performance Racing, the ZL1 1LE components were mostly concept parts, but they have been incorporated in the production Camaro ZL1 1LE and many are available for purchase from Chevrolet Performance. That means any racer with a Gen Six Camaro SS can use them to build a more competitive racecar.

CAMARO SS PRODUCTION COMPONENTS

LT1 6.2L V-8 engine
Six-speed manual transmission
Brembo performance brakes
Limited-slip differential

CHEVROLET PERFORMANCE PARTS

• ZL1 1LE-Spec Multimatic DSSV® Lowering and Handling Suspension Upgrade System (P/N 84352121) — Forged on the track and developed for the track-capable ZL1 1LE, this suspension system features Multimatic DSSV® dampers, combined with front and rear coil springs, and a ZL1 1LE-spec front sway bar. Ride height is reduced by up to 10mm and the system offers a 22 percent decrease in roll gradient, as well as a 245 percent increase in front spring stiffness. The front ride height is also adjustable for corner weighting and track use, with the ability to quickly switch from street to track camber settings.
  
• ZL1 1LE-Spec Suspension Upgrade System (P/N 84352119) — This kit complements the ZL1 1LE-Spec Multimatic Lowering and Handling Suspension Upgrade System (P/N 84352121). This off-road-only, track-tested system offers racers front ride links, front handling links, rear upper and lower trailing links and rear knuckles, as well as stiffer bushings and ball joints to reduce suspension flex. Compared to the Camaro SS, the upper and lower trailing links are 71 percent stiffer, while the rear link inner bushings are 58 percent stiffer. There’s also a 4 percent reduction in roll gradient in addition to 1LE Spec Multimatic Lowering and Handling Suspension Upgrade System enhancement.
  
• ZL1-spec solid-mounted rear cradle mounts — These mounts help reduce deflection in the rear suspension, for enhanced stability and more direct handling.
  
• ZL1 rear spoiler — This aggressive ZL1-style spoiler kit can reduce vehicle lift on the track for Camaro LS, LT and SS models when used with the Camaro SS accessory ground effects or front splitter package.

ZL1 1LE CONCEPT PARTS

• ZL1 1LE front fascia and front fenders
• ZL1 1LE grille
• Front splitter and dive planes
• ZL1 extractor hood

The Camaro TA4-Spec race car joins approximately 20 additional Chevrolet models this week at the SEMA Show, Oct. 31-Nov. 3.

A little confused by the article. So the car in the picture(the race car) is a standard SS with ZL1 body parts and 1LE underpinnings?

[vtirocz]

Sweet! I wonder how the first part number alone (shocks, springs, swaybar) on a regular SS compares to a SS 1LE.

Anticipating this package is one of the reasons I got the non-MRC suspension.

Pretty much a ZL1 1LE minus the LT4 engine. The car I was asking for. Now time for the "street legal" version. This car is going to be fast around the tracks.

I tried those part numbers @ thatgmpartsguy.com and they bring back "No results".

so they are making this a production car? What makes a ZL1 a ZL1 if it doesn't have the LT4 seeing that the suspension is now 1LE? Forgive me just trying to understand.

It could start as a production car or a body in white. Not sure what the Trans Am rules are. Either way it's turned into a race car homologated to run the TA4 spec class in the Trans Am Series. Much the same way The Pratt & Miller GT4 spec Camaros were built to race in IMSA and PWC. It will not be produced on the production line for sale to the masses.

Okay, thanks. That makes sense

[Mr. Wyndham]

This is an example of what parts you can buy from Chevrolet Performance. It won't be a production car as-is.

Still....pretty cool!

Glad I wasn't the only one with that line of thought. Was hoping there'd be a DSSV suspension kit like the Z28 kit for the 5th gens.

Kinda seems like this would fit the Z28's M.O. eh? ZL1 1LE underpinnings but naturally aspirated?

Finally... we will forsure be seeing all the ZL1 1LE goodies trickle down to us peasants.

Correct. Similar to the camaro GT4. They use the ZL1 bumpers for the added benefit of that wide open mouth for cooling and canards.
