Repair-It

Found these... Never heard of this company. If I am going with the "who cares, they are just winter rims" these are at least not a hideous aftermarket style.

More 1LE Z/28 similarities:

The Z/28 has a torsen diff (unique to Z/28) with a 3.91 gear (same as 1LE) in the same housing as the SS (and SS/1LE). They didn't use the ZL1 diff as it is much heavy.

So different diff type but same gear and same housing.

I also read somewhere that the 1LE and Z/28 share the same trans, but haven't confirmed that yet.

Here is what wiki says:

The Camaro Z/28 is a version of the Camaro SS with a full aerodynamic package designed to produce downforce at track speeds. The package includes a large splitter connected to an underbody panel, fender flares over the front and rear wheels, extended rocker panels, redesigned rear spoiler and a functional diffuser. Other changes include interior trim in matte-metallic Octane finish, a flat-bottomed steering wheel, standard Recaro seats with microfiber suede inserts and manual adjustment, elimination of the seat-back pass through, high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom, a 7.0L LS7 V8 engine co-developed with Corvette Racing, racing-style cold-air induction system with large K&N air filter, standard dual mode exhaust system with larger-diameter pipes, Tremec TR-6060 6-speed manual transmission, limited-slip differential with a helical gear set, 19-inch diameter wheels with Pirelli P Zero Trofeo R 305/30ZR19 tires, Multimatic DSSV spool valve dampers,[150] Brembo Carbon Ceramic Matrix brake discs (394 x 36 mm front and 390 x 32 mm), monoblock calipers (6-piston front, 4-piston rear), elimination of tire inflating kit (except for units sold in Rhode Island and New Hampshire), removed interior sound deadener and carpeting from the trunk, replaced the standard LN4 battery with LN3 battery, replaced standard 3.5 mm glass with thinner 3.2 mm glass for the rear window, removal of HID headlamps and foglights, removal of air conditioning (available as a stand-alone option)

There are a lot of differences (some significant). I like the part about RI/NH.

But yeah I think the 1LE is closer to an SS than it is to the Z/28. Also, notice they ran 19s for the extreme performance model. That validates all of my rants about wheel sizes. With the 1LE they made a concession to appearance but also likely development cost (wide 19s didn't exist in 2013 yet and developing them specifically for the 1LE would have blown their $3500 package cost).

All that said, I am a big fan of buying the car in the configuration you want. Trying to convert between trim models is an exercise in spending more than you anticipated, taking more time than anticipated and likely not capturing all changes anyway.

I don't anticipate doing much if anything. I was just curious.

The rims are interesting as I wouldn't mind getting an aftermarket rim that size if I could get tires with a bigger sidewall to match the width and height of the stock 1LE. A quick lookup shows that that isn't the case, so back to the OEM size for the 1LE.


Obviously I was interested in the upgraded suspension and brakes if they were a direct swap out/bolt on, but not for those prices.

The trans is apparently the same, so ok, and the rear gears are the same. Could change the diff to match the Z/28 if there was a good reason, or if doing more of a drag build, probably would be looking more at a ZL1 diff. Realistically, won't be doing anything anytime soon.

I just wanted to see what was out there and what made sense.


Right now, I would like to figure out a second set of rims and tires.

What I think of the Z/28 stuff:

The Camaro Z/28 is a version of the Camaro SS with a full aerodynamic package designed to produce downforce at track speeds. The package includes a large splitter connected to an underbody panel, fender flares over the front and rear wheels, extended rocker panels, redesigned rear spoiler and a functional diffuser.

The underbody panel probably wouldn't hurt for mpg - aero without causing drag. I could see fender flares if you were doing a drag build and wanted wider tires. I really don't need most of this stuff.

Other changes include interior trim in matte-metallic Octane finish, a flat-bottomed steering wheel, standard Recaro seats with microfiber suede inserts and manual adjustment, elimination of the seat-back pass through, high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom, a 7.0L LS7 V8 engine co-developed with Corvette Racing, racing-style cold-air induction system with large K&N air filter, standard dual mode exhaust system with larger-diameter pipes, Tremec TR-6060 6-speed manual transmission, limited-slip differential with a helical gear set,

Ok, don't care about the octane finish, I have the flat bottom steering wheel, I'm good with the seats, don't need the expense of the LS7, already have an intake, don't need dual mode, bigger pipes might help??? trans is the same, and I don't know enough about the diff differences.

19-inch diameter wheels with Pirelli P Zero Trofeo R 305/30ZR19 tires, Multimatic DSSV spool valve dampers,[150] Brembo Carbon Ceramic Matrix brake discs (394 x 36 mm front and 390 x 32 mm), monoblock calipers (6-piston front, 4-piston rear), elimination of tire inflating kit (except for units sold in Rhode Island and New Hampshire), removed interior sound deadener and carpeting from the trunk, replaced the standard LN4 battery with LN3 battery, replaced standard 3.5 mm glass with thinner 3.2 mm glass for the rear window, removal of HID headlamps and foglights, removal of air conditioning (available as a stand-alone option)

Most of this sounds out of my price range. no point in changing from 1LE sizes. Brakes and suspension are way out of price range. I don't have HIDs, and I want AC.

I also know that the paint code is U8555 (black) with a base coat and clear coat.

In the SPID, GBA is Black also.

Is that possibly for the hood?

Don't think so. I was looking on the ZL1/1LE registry site: http://www.zl1registry.com/1le-specs.php

They have a SPID for each color, all should have the hood, and I do have the black one in my SPID so I assumed that was right.


I think I am going to try to do a full SPID breakdown at some point, and also need to get the touch up paint so I was looking it up.

I think this is what I am looking for:
https://www.amazon.com/Genuine-ACDelco- ... =8-1-fkmr0

There is a lot extra in the number though.

My label says: BC/CC U 8555 01A


This says: Genuine GM ACDelco 2-In-1 Touch Up Paint Gloss Black 41 41U GBA WA8555 & Clear Top Coat

Actually, this is it, because that GBA is in my SPID.

Interesting clutch issue.

Sounds like the fix is a ZL1 clutch, and makes the feel more linear and engages lower. Interesting. I should look to see if this was already fixed.

Hmm. I do know that there is a pretty common issue with T56 cars where during heavy use the clutch pedal may stick on the floor. I had flushed my clutch fluid before my NC trip, but did occasionally run into the issue during very hard, continuous driving (nothing you could ever hope to do in southern New England, on the street, by the way). Shifting to neutral and cycling the clutch a few times seemed to clear it up. It is recommended to flush clutch fluid fairly frequently as a good preventative action and that seems to have worked fine. Every other oil change is what I do. It is a bit of a pain but the key is knowing where the bleeder screw is (goes to the slave cylinder area) and getting a pressure bleeder that mounts to the clutch reservoir so all you have to do is go under the car and crack the bleeder.

So the Camaro MAY have this issue but there also seems to be another issue that I don't fully understand. Actually I looked at the TSB and it specifically says this is NOT for the issue that I just explained above (which was still known to GM on the 5th gen Camaro even though the issue had been around for a good 10+ years prior). This is in fact something else, as I suspected.

But yeah apparently that would improve clutch feel. Would be nice if GM paid but from what I remember, TSBs are only covered if inside a warranty period.

According to this TSB, it includes replacement of the clutch pedal assembly, clutch master cylinder, reservoir and cap. It has nothing to do with the actual clutch (i.e. it is not a ZL1 clutch, in fact they don't even touch the slave, so the transmission obviously stays on the car). May be the ZL1 clutch pedal (includes return spring I guess) and master cylinder, though. I guess the other good point here is that there is nothing wrong with your clutch - it's the actuation part of it that is the issue.

I would certainly take a free repair but not sure what the cost would be. $500? $1000? Somewhere in there probably.

EDIT:

The dealer I bought my car from just quoted me 500 bucks to do this TSB, also stated its not covered under warranty. I'am missing something???

Exactly. And yes he is missing something. TSBs are not recalls. And for good reason. Do you have any idea how many car guys storm into dealers and demand all the TSBs be installed for free on their cars, even if their vehicle is NOT effected? Adam will certainly confirm this I am sure.
