Your link didn't work!!!

 

Can anyone tell me if any 1990 formulas are 1LE's?

 

WS6 was not a std T/A option, only on GTAs was this the case.
On Firebirds there were 3 suspension levels, on the Y99 and WS6 you get the Performance Badge

If the caps came with the rims and the rims came with the car I would say yes its a WS6


As you can see from the chart, there were no Formula 1LE's made in 1990

In 1988, GM offered F-body owners more then just the standard Formula and T/A. It was selling race-ready F-bodies that were just an option box away. Coded "1LE", these specially ordered Firebirds and Camaros have come with everything from bigger brakes to aluminum driveshafts and special gas tanks. Most people are unsure about the early 88-89 1LE cars. No literature or road test really exists for them, at least nothing that explains the option.

The reason 1LE cars exist is because of SCCA showroom stock racing. As the name implies, Showrrom Stock racing requires that all competing entries be absolute production cars. Natureally, GM wanted to widen its advantage over the competition, so to utilize items like bigger brakes and lighter driveline pieces on its race cars, it first needed to make them available on the production cars. It wasn't until 1990 that automotive magazines, dealerships and the general public really started to catch on to these cars. They started popping up in everything from Car and Driver to Popular Mechanics. The word had leaked out about these killer factory race cars and, suddenly, everybody wanted one.

To get your hands on one of these machines, all you had to do was order the G92 Performance Axle Package, which got you 3.23(350 auto), or 3.42(305 5 speed) gears, along with a limited slip differential, an engine oil cooler and a freer-flowing exhaust. This option along with C41, would also net you bigger brakes with PBR aluminum calipers and larger 11.4 inch rear disc brakes with matching aluminum PBR calipers. Also included in the 1LE option was a special fuel tank with increased baffling for reduced fuel starvation in the corners. You also ended up with a specially balanced aluminum driveshaft that decreased reciprocating weight in the driveline considerable. Special shocks, struts and srpings were also included with the 1LE package, and in '89, a new dual cat converter exhaust system also became standard on the 1LE's adding another 10 horses to the TPI engine. Something you couldn't benefit from were any of the birds many convenience items. About the only choice you had when ordering a 1LE car was exterior color and license plate bracketry. This was GM's way of discouraging average people from buying these cars. The result was low double digit numbers for these cars, in every year of production for the third generation. More 305 5 speeds were produced than A4 350s, but the 5 speeds are harder to track down because the majority of them went straight to the track.

ALL Formulas had WS6. Every single one of them.

1LE? I doubt it. Have your RPO list? Check it. What size are the front brakes? It'd have to be TPI as well, most were 5.0 5-spds but not necessarily all.
