i got this from the G-body.org website, this is some great info
In 1985, Pontiac Motor Division knew it had a problem. While its NASCAR competitors (namely, the Monte
Carlo SS and the Ford Thunderbird) had developed far more aerodynamic bodies for their race cars, PMD was
stuck with the rather brick-like front end of the Grand Prix, which in all certainty had the least wind-friendly
nose of any G-body. This hindered the GP's ability to compete, to the degree that not one race in 1985 was
won by a Pontiac. 14 of 28 were won by the T-bird and the rest split among the Monte SS and the Regal. So
early in '86 the engineers at PMD came up with a plan: to create a much more aerodynamic version of the Grand
Prix using entirely bolt-on parts. They built somewhere in the neighborhood of 1200 of these cars, fulfilling
NASCAR's requirement of 200 street versions of a race body.
The newly named Grand Prix 2+2 (a name used in the early 60's on Catalinas) looked dramatically different
than the base GP, but the only changes were a new header panel with 4 black honeycomb grilles, sloping rear
glass similar to the Monte Carlo Aerocoupes of the same year, and a special trunklid with a 4-inch rear spoiler.
The 2+2 rear glass was different than the Monte glass in that it went from the roof to the spoiler, leaving
virtually no trunklid. The car was sprayed in two-tone gray and silver with red striping just above the rocker
panels and at the top of the fenders.
The 2+2 was slated to receive the HO 305 from the Monte SS and the F-bodies as well as the Monte SS's
dual exhaust set up but since demand was so high for those items, the 2+2 was turned down and instead
received the standard 157 hp 305 and single exhaust. The car also came with a 200 4-R 4-speed automatic
leading to a limited slip, 7.5 inch, 10 bolt rear end containing 3.08 gears. Pontiac lobbied for the 3.73 gears that
were in the Monte SS but the EPA only allowed that ratio to be mated with the HO powerplant. The 2+2
launched to 9-second 0-60 times and ran low 17-second, 82 mph runs in the quarter mile.
Where the 2+2 did shine was handling. The 2+2 got the F-41 suspension package, consisting of siffer
gas-filled Delco shocks, 12.7:1-ratio steering box, and larger 29mm front and 16mm rear sway bars. The car also
came with 215/65R-15 Goodyear Eagle GT's on steel 15x7-inch Rally II rims.
On the inside, the 2+2 came standard with a full analog guage package and power locks, windows, and
seats. The interior came dressed in gray cloth and featured a floor shifter in a full-length console. For this
luxury, as well as the handling and exterior upgrades, the 2+2 buyer could expect to shell out $17,800 dollars.
Thanks entirely to the redesigned exterior, the Grand Prix 2+2 actually notched a few wins in '86 and '87, only
to be replaced by the completely new 1988 model. As always seems to happen to Pontiac, they got the short
end of the stick in terms of performance options. But considering that the changes were designed and
implemented in a flash, the 2+2 did what it was intended to do - put Pontiac on equal ground in the NASCAR
standings.
