For two years I have been on this message board and seen "1le" parts reccomended to people. I have searched and searched and have yet to find out what car(s) are 1le. Could someone explain this to me? Thanks a ton, haha.

 

The 1LE was an option code for a stripped down version of the Z28 (reduced weight by deleting power windows, etc). It also had upgrade suspension components (stiffer rubber bushings, larger sway bars, different springs rates, etc.).

 

Here's a great write-up from the F-Body.org FAQ section:

Q: What's included in the 1LE performance package??

A: The package required these options (Z28/Formula, respectively):

Basic option group (FZAB/1SA)
A/C delete (until 1996 when A/C became standard)
6-speed tranny or performance rear axle with the automatic (GU5/G92)
Z-rated tires w/ 150 speedo (QLC/QLC)
Base stereo
and it consisted of:

Higher rate front springs (360 lbs/in for mid-1994 and after)
Variable rate rear springs (130-180 lbs/in for mid-1994 and after)
Stiffer front and rear shocks (Koni double adjustable for 1996 and after)
Harder bushings (front upper/lower and rear control arms)
Larger diameter anti-sway bars (32mm front, 21mm/19mm rear)
Increased cooling (for 1995 and after)
Engine oil cooler (1993 - 1995)
The 1993 1LE cars had the same springs and deCarbon shocks (but with much stiffer valving) as on the stock Z28s and Formulas. Initial 1994 1LE cars received the same set-up, but sometime during model year (between Dec 94 and Mar 95), the 1LEs received stiffer (higher/variable rate) springs and the shock valving was slightly reduced (but still considerably stiffer than the stock deCarbon valving). Due to the stiffer springs and modified valving, the 21mm rear sway bar was dropped in favor of the 19mm bar (which was the same as on the stock Z28s and Formulas). In 1996, the Koni double adjustable shocks became standard on the 1LE cars. Increased cooling on 1995 and after models was accomplished by the addition of an air conditioning radiator baffle even though no AC was available in 1995. Also, after 1995, in order to get the 1LE on the Firebird or Trans Am you had to order the WS6 package.

Here's a list of suspension parts and prices for 1994 models:

The Lou Fusz automotive network of dealers have items at the wholesale price.

 

That is not what I experienced, wrong front springs I had to protest the charge on my credit card.

The front springs are not 1LE, not even close.

Rears springs are 1LE and the front sway bar is 1LE.

Not sure about the shocks.

z28

 

I snagged my 1998 1LE for $10,250. That made me happy. I have yet to adjust the springs on the car though. I ran it at my quarter mile track and had problems getting it to hook up, the weight transfer is minimal. All in all the 1LE has treated me good.

 

How would one go about identifying sed 1LE option on his/her car?

really, I'm serious....

 

The sticker in the glove box.

Look for "1LE" in the dozens of three digit codes on the sticker.

Z28

 

I just noticed on the gyrhead website they say the Z28 bar is a solid 30mm and that the 32mm hollow is softer?

Anyone have one of these super rare 30mm solid bars

 

The sticker that I found my code on is on the inside of the driver's door, not in the glove box.
