Do I have an 89 1LE?
When I purchased my vehicle, it was said to be a 1LE IROC-Z. I didn't believe it, as the RPO sheet is gone and the vehicle has an assembled title. Well I took my vehicle down to 1MeanZ to give it a good appraisal, and decided it could actually be a 1LE.
I received paperwork from the previous owner documenting the previous VIN, which we were able to verify an exact match on a front bumper piece. The vehicle is hard top, has an aluminum drive shaft, hallow 32mm sway bar, large 2 piston front brakes with what seems to be an original one piece spindle, G92 rear end(?), and dual cat exhaust.
I have the original VIN available if it is any help!

Re: Do I have an 89 1LE?
1MEANZ is very knowledgeable and will be able to help you document the car. The last 8 of the VIN are stamped on the upper front rails under the fender to confirm origin of the unibody. What happened to the VIN?

Re: Do I have an 89 1LE?
The vehicle has an assembled VIN.
It has power accessories and AC which I've read are removed from the 1LE package, but it seems to have everything a 1LE would.
It was my hope someone might know some information that could confirm our suspicion based on the original VIN.

Re: Do I have an 89 1LE?
Unless the vehicle is an exported vehicle, there is no public (free) resource to get that information from a VIN given it's a 1989. You would have to purchase a factory invoice from GM.
And given it's a nearly a 30 year old vehicle with an assembled VIN, it's certain parts were swapped.

Re: Do I have an 89 1LE?
Where is there a white sticker in the hatch located. Is it on all thirdgens? My car is home so I can't look. Is it a list of rpo's like under the arm rest?

Re: Do I have an 89 1LE?
The SPID sticker was moved from the center console to the locking cargo area in the hatch in 1991.
It's a really long shot to look in there for any ThirdGen that is 1990 and older because it's not supposed to be there.

Re: Do I have an 89 1LE?
The rpo sheet was in the center console, I can see fragments of it. It has just worn away beyond any legibility.

Re: Do I have an 89 1LE?
İf u were in canada any gm dealer could print out option codes from your vin. Being a us car not sure. Look up closest canadian dealer to you and call parts/service and ask if they can punch it into computer. İf it comes up, ask if 1le is in build. Good luck

Re: Do I have an 89 1LE?
If you want to know... go to http://www.gmmediaarchive.com/ and order yourself the dealer invoice... that would tell you... If it is a 1LE it will be worth the $50 investment.

Re: Do I have an 89 1LE?
Why is it funny? I'm usually the first guy to emasculate someone who thinks they have a rare or valuable thirdgen. I've spent more time under this car than over it, and if the brakes were swapped, it was done LONG ago, because the grunge on them is a dead ringer to the grunge on the rest of the car. The rotors are the proper 12" and the spindles are real deal 1LE spindles. No brackets, no tricks, not a swap with Ed Miller's kit etc.
I agree it's unlikely that it's a real 1LE, and this car has a questionable history. But it is a hard top, with an aluminum driveshaft, dual cats, 3.27 gear, and the big brakes. It also has leather seats and power windows and cruise control. The fog lights are some aftermarket stuff, I can't tell if it had any originally or not. The car DOES have AC, which looks to be original, which I know disqualifies 1LE as far as anyone here knows.
The car is either a real deal somehow, or it's been updated early in it's life with all the right factory parts by a very well informed thirdgen enthusiast.

Personally I would love to see it be a 1LE, it would just blow the roof off of everything we think we know about them.

Re: Do I have an 89 1LE?
A while back, someone ran a VIN for me and was able to get me every single RPO code for my Tahoe since the original glove box was swapped out at some point in the trucks past. Its a 1998 model year so Im not sure of there is a way to do the same with these cars. I guess it all comes down to how well someone or something (computer) kept records.

Re: Do I have an 89 1LE?
There is, only if it was A) shipped originally to Canada, or B) if it is a 1990 - 1992. Nothing from the US for 1982-1989 for the F-car... Sucks really, it would have been nice to have access to that information

My apologies, it would be great if it was a 1LE and from what I understand a couple of them did get built in 1989 - there was one in the DC area about 10 years ago.
That being said, everybody wants to have a rare car and will sometimes build what they want when they can't find or afford what they want. This is why there are twice as many 1969 Z-28's or Judges as were ever produced and how correct 1LE parts can find their way onto cars they didn't belong on.
If this car turns out to be real, I'll be very happy to hear it!

Re: Do I have an 89 1LE?
'It's only a brake package'...Please, it is a balanced performance package that included and deleted certain options. There are multiple threads that address the 'just a brake package' thought so won't do that here. Folks do some hating on the the 1LE's.

Re: Do I have an 89 1LE?
These discussions are good because they challenge the limits of what we think we know about these rare cars and what we actually do. JT has been helping me with some of the production numbers on the 1991 Formula 1LE cars and some interesting statistics have come out:
Of the 46 Formulas built - 9 came equipped with C60 Air Conditioning and 8 with T-tops (none shared both options). Where Chevrolet said no, Pontiac apparently said yes when it came to 1LE's in fact 6 of the 8 t-top models were built with the 1SC package!
Too bad Comp 9 doesn't include the data back to 1989 because that kind of information of the 26 TA's built that year would be great!

Re: Do I have an 89 1LE?
Funny thing is that the statement I found it on was for the 1988, which there was 4 1LE's made... in 1989 there was 111 made (IIRC)...

Re: Do I have an 89 1LE?
Also, I believe all of the 1LE Firebirds got the cross laced rims... The Camaro is kind of up in the air for 1988 & 1989... I have never seen one, but it might make sense since they were the lightweight wheels, which helps with performance, lowers unsprung weight, and overall weight. I know the GNX got the Black Cross laced wheels..

Re: Do I have an 89 1LE?
That's what I have seen too... I do not believe the 1LE Camaros got the cross laced rims, it was based on that little website that has bad information. http://www.gm-efi.com/features/gm-ef...vrolet-camaro/
First there were NO L98 1986 Camaros... I found the reference to the 1LE and the cross laced wheels interesting, but it has no weight. THe article author is clearly not a tgo subscriber.

Re: Do I have an 89 1LE?
Not sure why but this whole time I've been reading this I've been under the assumption this was a Trans Am - I just went back and re-read the whole thing and saw it was an IROC.
Unfortunately there is no evidence A/C showed up in a 1LE Camaro and so far the only positive confirmation we have of it showing up in a bird is 9 1991 Formula 1LE's with the L98.

Re: Do I have an 89 1LE?
On the back of the wheel, crosslace, in between the lug holes are recessed areas that have info like rear wheel, 16 inch, etc. in one of those recesses should be a round circle with the year on top and the month on the bottom. I have a March of 1990 built 1991 and the date code on one rear wheel is 12/89.
So there were nine L98/C60 1LE's built??? Did not know that.

Re: Do I have an 89 1LE?
To answer your question however, the L98 appears to only be in the Formulas in 1991 & 1992 and no CC1 & C60 do not seem to be combined in the data I've pulled.

Re: Do I have an 89 1LE?
Nope, No 1LE, CC1 & C60...
Plenty of 1LE + C60 (B4C Camaro perfect example, as well as several Formulas) and
plenty of 1LE + CC1 (No Camaros that I am aware of, but several Trans Ams and Formulas)

Re: Do I have an 89 1LE?
So I received the invoice copy from the GM Media Archive. Now I need your help to decipher it!
This excerpt is from camarowiki.com
On the invoice you'll see it has the 5.7L TPI, and also has the G92 and G80 codes. Additionally, AC and power accessories are added in 1SD not C60 & A codes.
So, is it a street 1LE, or a race series 1LE with delete items added in specially? Or not a 1LE at all?
This excerpt is from camarowiki.com
Then in 1989, the option became more well-known as 111 were produced that year. The package was obtained by ordering the following:
Level 1 IROC-Z with 5.0 TPI engine (LB9) with 5 speed or 5.7 TPI engine (L98) with 4-speed automatic. These Camaro's had 145 mph speedometers and 5500 rpm redline tachs. Optional axle ratio (G92) (305/3.45, 350/3.27) and its required options G80 Limited-Slip rear axle
Package consisted of (G92 Was Ordered With A/C) [Street Vehicle]:
engine oil cooler 4-wheel disc brakes Performance exhaust system (N10) (dual catalytic converters) Tires P245/50 ZR16 Goodyear Gatorback
Note:
G92 ordered WITH A/C was classifieds as a Street vehicle.
G92 ordered WITHOUT A/C was classifieds as Race series.

Note:

G92 ordered WITHOUT A/C was classifieds as Race series.
1989
Chevrolet built 111 "1LE" 1989 Camaro's for the SCC A Showroom Stock racing series. But 1LE wasn't ordered like other RPOs. Ordering the RPO G80 Limited-slip rear axle & G92 performance axle with an IROC-Z Coupe triggered the 1LE RPO. Here's how it worked: When G92 was ordered, it forced several other options including engine oil cooler, 4-wheel disc brakes, dual converter exhaust and P245/50ZR16 tires. A 1989 Camaro with G92 had to have either the 350ci (RPO B2L) engine with 4-speed automatic transmission, or the 305ci (RPO LB9) with 5-speed manual. These Camaro's had 145 mph speedometers and 5500 rpm redline tachs. If RPO G92 was ordered with air condition ing, the cars were built as street vehicles. If air conditioning was not ordered, Chevrolet added 1LE equipment for the race series. This included aluminum drive shaft, big front brakes adapted from the Corvette, fuel tank baffles, specific front and rear shock absorbers, and different jounce bumpers. Also, fog lamps were deleted for weight savings and better air flow to the radiator.

A 1989 Camaro with G92 had to have either the 350ci (RPO B2L) engine with 4-speed automatic transmission, or the 305ci (RPO LB9) with 5-speed manual. These Camaro's had 145 mph speedometers and 5500 rpm redline tachs. If RPO G92 was ordered with air condition ing, the cars were built as street vehicles. If air conditioning was not ordered, Chevrolet added 1LE equipment for the race series. This included aluminum drive shaft, big front brakes adapted from the Corvette, fuel tank baffles, specific front and rear shock absorbers, and different jounce bumpers. Also, fog lamps were deleted for weight savings and better air flow to the radiator.
So, is it a street 1LE, or a race series 1LE with delete items added in specially? Or not a 1LE at all?

Re: Do I have an 89 1LE?
It appears it's not a 1LE, or there would be 1LE listed in the left margin with the other codes. Looks like the car has had lots of other mods along the way. Looks like the leather seats were swapped, as were the brakes, and the driveshaft.
The brakes were likely done a long time ago by someone with knowledge about these cars and who was willing to spend a LOT of money....

Re: Do I have an 89 1LE?
So even though the RPO wasn't an option it would still appear in the invoice?
But 1LE wasn't ordered like other RPOs. Ordering the RPO G80 Limited-slip rear axle & G92 performance axle with an IROC-Z Coupe triggered the 1LE RPO. Here's how it worked: When G92 was ordered, it forced several other options including engine oil cooler, 4-wheel disc brakes, dual converter exhaust and P245/50ZR16 tires.

Re: Do I have an 89 1LE?
This is an invoice though not a build sheet. They don't have build sheets available.
These are all present
I'm wondering since it wasn't something you could order, if it wouldn't show up on an invoice?

Re: Do I have an 89 1LE?
It seems you have a super duper nice car, the 1LE brakes are a huge plus in my opinion, I am thinking of putting them on my 89 Convertible because they are much better than the stock brakes.
No worries, it is a cool car regardless...
