1LE
Greetings all. How can I tell if my 1989 Firebird Formula has the 1LE suspension package? Thank you

Re: 1LE
The easiest visual clue is to look at the front brake calipers. If they're rusty, they're cast iron. 1LE calipers are aluminum, and won't rust. They may be shiny gray, dull gray, or even white, but they won't be rusty. If you see rusty calipers, you can be 99% sure the car never had 1LE.

Re: 1LE
IF the TTAs and firehawks? are thrown into the 1LE count, things do change a bit but do they count as a true 1LE since they have AC?.
What about B4C cars? are they counted in the 1LEs?

Re: 1LE
The rpo code decal should be in the center console or drivers side storage compartment in the back. I presume your car is a 5speed? I'm pretty sure there were no 1LE auto's ever made. Yes it should have the big PBR finned aluminum calipers.

Re: 1LE
Speaking of 1LE's Matt here has a really nice machine. I'd argue with him about the best color tho!! LB

Re: 1LE
IF you take into account the 1989 TTA that had the 1LE brakes but not the 1LE RPO, then technically yes, there were slightly more Firebirds that got the brakes than Camaros. WHY the 1555 TTAs SPID was devoid of the 1LE, when they got the 1LE equipment is beyond me. The only thing I can think of is there was something else with the 1LE that the TTA didn't get or the TTA had something that made the 1LE incompatible.

Re: 1LE
I ran across a Formula that had the Wonderbar (it was not a 1LE), the owner said he owned it from day one, and didn't put it on... Never could figure that out, wish I would have noted the VIN.

Re: 1LE
Cool, I honestly don't think I have ever checked to see even on a 1LE bird. Will be watching from now on tho.

Re: 1LE
No N10 or JG1 rpo on the TTA kinda makes sense it wouldn't have 1LE either

Re: 1LE
Also note the front struts and rear shocks were unique to the 1LE package ... and with the lighter weight of the V6 turbo, the front struts would be too stiff perhaps? Being the TTA was not a race car, have a more comfortable drive was the choice.
Back to the original poster; the Formula should not have had 1LE stuff from the factory, but it might have been added after. As Drew says ... check your front brake calipers and see if they are aluminum (with two visable discs).

Re: 1LE
Gentlemen, checked for a wonderbar on my 1LE '91 T/A, not there. I had to go out to the barn and check as I didn't know for sure myself.

Re: 1LE
For those of us who are not knowledgeable on the subject can someone please enlighten us on what to look for on the RPO code sheet to identify a 1LE car or it the VIN where you find out?
Thank you guys in advance for your time

Re: 1LE
And what strikes me most about this is R6U Means "CREDIT IN LIEU OF FUEL" $16.00-
What the heck is that?

Re: 1LE
Thanks to all for the information. My Formula doesn't have the 1LE option. I also sent away to allied Vaughn for a copy of the dealer invoice. Lots of info there too.

That is one highly optioned 1LE Chris, great to see the window sticker on such a rare car. Car is in awesome condition to boot.

Re: 1LE
The rarity of the earlier 1LE's makes it somewhat difficult to plot out what was or wasn't included in the "performance package".
Also ... with my 89 1LE, it has a few codes R6's I think which I had not found on US cars. Could those be part of the difference or just marketing packages for odd things?
With the TTA, it obviously does not have "all" the components of the performance package hence no 1LE.
I'm curious what part number is on your front struts? 1LE stock number or the earlier number.
Mark.
