1969 Chevrolet Camaro - Bionic Camaro Rear Clip Install

1969 Chevy Camaro Rear Clip Installation

When we last left this Camaro it was undergoing some extensive performance surgery at Total Cost Involved (TCI). TCI just finished developing its latest project, a tubular bolt-in front clip designed for the first generation Camaro. Not being one to leave a job half done, the backside of this F-body is also being reworked with TCI's four-link, coilover disc brake setup. With the TCI tubular front clip and rear four-link in place, this Camaro will soon demonstrate its blacktop bionic powers on our proving grounds at California Speedway.

Perhaps the most advantageous action associated with this four-link setup is the engineering and design that went into its creation. If the thought of cutting into your Camaro's floorboards, and fabricating brackets gives you the shivers, shiver no more. Truthfully, the welder you convinced your wife that you just had to have will remain dormant during this four-link install.

This TCI four-link bolts right into the existing holes in the vehicle. Of course, it will be necessary to drill a few of you own, but it is nothing that can't be accomplished in the home garage with a decent set of tools, and a floor jack.

With this rear end package, it's all the available options and upgrades. Let's take a look at a few of the options before we dive under the car.

So here we are starting with a clean slate. All the old components have been removed, and it's action time. The removal of the rear suspension and the installation of the new one can easily be performed in the two-car garage provided that you have the right tools and a sturdy set of jack stands.

So here we are starting with a clean slate. All the old components have been removed, and

Rear End:
The standard rear in this kit is a new 58 1/2-inch unit with new 31-spline axles from Currie Enterprises, and it can accommodate some wickedly wide wheels. The optional gearing is as follows: 3.00, 3.25, 3.50, 3.73, 3.89, 4.11 and 4.56. Positraction is also another available option. A Panhard bar is supplied when a 9-inch rear end is used, and a track bar is supplied when a Chevy rear end is used.

Brakes:
Brakes range from 12- and 13-inch Wilwood drilled and slotted zinc washed rotors, with optional painted or polished calipers. Standard GM 12-inch smooth rotors and GM calipers are also available. Drum brakes and the backing plates are another possible option. All brake kits have an internal parking brake assembly similar to that of the Corvette.

Four-Link:
The four-link options include billet adjustable coilovers (manufactured by TCI) or polished billet coilovers, chrome bars with chrome coilovers, polished stainless bars with chrome shocks, antisway bar (also with chrome option). If coilovers are not desired, Shockwave airbags from Air Ride Technologies are also available.

Before digging in, an inventory of all the necessary parts and hardware is laid out. The TCI kit comes complete with every bit of hardware needed to make it work. What you see here is the complete kit after it has been powdercoated. The kit comes in bare metal and the color choice is up to you.

Prior to the installation of the four-link bracket, some grinding will have to be done. A 1 1/2 inch diameter needs to be cleared from the sheetmetal for the bracket to fit.

After the crossmember is mounted flush and level to the uniframe, clamp it into position. After clamping, a 3/8ths drill guide (provided in the kit) is used to drill perfectly level holes through the unibody frame.
