From the beginning, Project Talladega has stuck doggedly to a NASCAR aesthetic. Right or wrong, we feel the stock car racing theme is the most fitting one for a '75 Laguna, since that is primarily how history will remember that marque. So far, we've successfully pulled off the bodywork, paint, graphics, wheels, tires, and unique NASCAR-inspired exterior pieces, but only recently started on the serious performance pieces. Early on, we discovered that the suspension experts at Global West specialize in chassis bolt-ons for '73-77 GM Colonnade A-bodies like our Laguna. Since one of the eventual goals for Project Talladega is to do some road course and autocross work, we had to avail ourselves of Global West's full line of bolt-on suspension parts, which we detailed in our June and July issues.
At that point, we found ourselves in somewhat of a bind. By sticking with the NASCAR look and the attendant 15-inch steel wheels, we discovered the primary shortcoming of the vintage stock car vibe: small brakes. At this point it's worth noting that from the beginning, the sole purpose of the Pro Touring movement and the big-wheel look was to fit larger, more capable brakes. Everything else-including the styling-came from that initial need. You can therefore see the irony of our current situation. We are, in essence, creating a Pro Touring car, without the Pro Touring look.
Global West offers a disc...
Global West offers a disc brake package called Cat 5, which we originally thought would fit our 15-inch Bassett steel wheel. The Cat 5 system has a special two-piece 11.75-inch rotor with a custom billet hub; calipers are four-piston Wilwoods. The offset on the hub is designed so that a 1 1/4-inch-wide stock car rotor can be used while keeping the load on the spindle in the correct place; these are widely used in stock car classes where a stock 15-inch wheel is required.
At first, we investigated all the midrange-priced brake systems with 13-inch rotors and dual pistons-the center mass of the Pro Touring bolt-on market. That was a losing proposition, as the calipers would tag the drop center of the steel wheel every time. No problem, we'll just step down to an entry-level 12-inch system with smaller dual-piston calipers. Amazingly, nothing in an entry-level system would clear the drop center of our Bassett steelies either. What we discovered is that the Bassett wheel we chose has an even deeper drop center than the stock 15-inch steel wheel. We hit the max level of frustration after trying out a very trick Cat 5 system from Global West that uses a slim dual-piston Wilwood caliper on a beefy two-piece 11.75-inch rotor bolted to a custom aluminum hub. These brakes were especially designed for use in racing series that require 15-inch steel wheels. In spite of this system's wide-spread use in stock car racing (and with different types of 15-inch steel wheels), they still hit the drop center of the Bassett D-Hole Lightweight design. Do not pass go, do not install cool brakes. Bummer.
Back at square one, we knew at least one brake system that fit: the stock system. It turns out that Global West offers a front brake system for our Laguna that uses a stock caliper from a '70-73 Camaro. (This is also the same caliper that's on our Laguna.) While not the optimal situation, the single-piston Camaro caliper does get a boost in the leverage department from Global West's larger 12-inch gas-slotted 1LE rotor. (The stock rotor is 11.75 inches.) In order to use the larger rotor, Global West mounts the rotor and caliper on a new spindle with a longer caliper mounting ear. The best part is that the whole thing fits inside our Bassett steelies.
Packaged as part number DB1812, the Global West brake system comes pre-assembled with new 12-inch zinc-washed and gas-slotted 1LE rotors, new (not reman) single-piston '70-73 Camaro calipers, new spindles, bearings (packed), seals, dust plates, Wagner brake pads, and new braided stainless steel hoses. The price of $1,208 for the kit is inclusive, but depending on the customer need, can be customized. We decided to use our original calipers and brake lines, which got us off the hook for filling and bleeding the system. This also saved us $230. For an extra $20, we upgraded to long 1/2-inch -20 ARP wheel studs to complement the NASCAR theme (7/16-inch -20 studs are standard). To pull off that look, we also needed the big NASCAR lug nuts, which we got from Bassett for $1.45 each.
 In the midst of the suspension...  In the midst of the suspension install at Global West's San Bernardino, California, facility, you can see in the foreground where we were in the process of trial fitting the larger Cat 5 brake system into the Bassett wheel. Note the 1LE rotor from the DB1812 system off to the right. Praising the Laguna's elegant slant nose is Global West's Eric Norrdin. |  The Global West Cat 5 kit...  The Global West Cat 5 kit was a no-go due to the severe drop center of the Bassett wheel. (Earlier, we had ruled out kits by other manufacturers as well.) That left just the Global West DB1812 system, which uses the stock-style single-piston caliper with a larger 12-inch 1LE Camaro rotor and a unique spindle to make it all fit together. We opted to reuse our original calipers to ease the installation and save a few bucks, but the DB1812 kit normally comes with new '70-73 Camaro binders and hoses. |  When you need to make up a...  When you need to make up a shortfall in brake torque due to a small caliper, you can often recoup much of this in superior friction materials. We had heard great things about the EBC Yellowstuff pads, and ordered a set to install. They'll have their work cut out for them when we hit the track. |
