Does the Z/28 not have more power? Is it not a different car in terms of suspension? That is like asking why a monster truck works better with huge tires than it would with 285/35/20 on my 1LE! Different vehicles will require different set ups based on HP, weight, suspension and other factors. The 1LE is a great car, but it ain't no Z/28. You should ask engineer Al!

I think what gajagfan was getting at is a comparison of the 1LE vs the ZL1 (that effectively supplied its wheels and two sets of front tires). The intended "lessened rear grip comparison" is the 285 relative to the 305 with both on 11's. Not 285's on 11's vs 285's on 10's. 1LE rotation vs 1LE rotation on a full ZL1 wheel/tire setup.
That's my take (and independent thoughts as well). It's getting a bit picky, but that's the kind of thing that makes the difference between "excellent" and merely "very good". On edit - it's interesting to note that the wheel width "stagger" on the Z/28 is only 1/2", vs the 1" for the ZL1 and 1LE. Norm |

In a trans-axle car with 50/50 front to rear weight distribution and the same weight as a 5th Gen the same set up would work well. Take out 800 or a 1,00 pounds, add more RWHP and you'll find wider rear tires work well. In a nose heavy 5th Gen matching front and rear tire sizes are mission critical. As far as asking an engineer at GM, has it occurred to you that we talk with GM guys all the time, but we respect their proprietary product knowledge and would never ask them a direct product question. It would be inappropriate for us to ask and may cost them their job if they were to answer. On the other had, were they to borrow any Pedders setup ideas we accept that as flattery In 2008 when GM needed some critical pieces for the Grand Am Prototype 5th Gen they asked if Pedders could deliver. We did and the EP6577 full bush, EP6578 insert and EP6579 inserts are a direct result of that project. In 2009 Pedders introduced the 305/30/19 all round wheel and tire fitment. In 2014 GM will debut the Z/28 with 305/30/19s all round. In 2009 Pedders introduced the 27mm solid front sway bar. Gm ran hollow bars until the ZL1 came out with a 25mm front bar and then the 1LE with a 27mm front bar. In 2009 Pedders introduced the CTS-V six pot front brake conversion on the 5th Gen. In 2012, the ZL1 was introduced with... wait for it.... 6 pot CTS-V front brakes. Jay Leno's twin turbo 5th Gen is on Pedders coilovers, sub-frame inserts and toe link bushes. The on track INDY and NASCAR Camaro Pace Cars run on Pedders coilovers, inserts and sway bars. We have done so much with the 5th Gen we wrote a Book on it so any member of Camaro 5 can setup their Camaro just like we do.

They had no choice with the front 305 fitment. The extra wheel and rubber had to move out, away from the strut. Closing the gap on the front and rear track is a side benefit further reducing understeer.

If you want to available the 1LE using OE parts order up a set of Z/28 wheels and tires as soon as they become available and swap out to a ZL1 differential and gear set. The ZL1 diff will put power down better in the curves and compensate for the shorter wheel and tire combination. On the other hand, if you never touch your 1LE it is a very very good automobile. Very good. |

By no means am I questioning your knowledge or abilities. The engineer made it clear, and I believe wholeheartedly that what you are calling balance, I am calling reduction / removal of the understear, which is what heavy Gen5 Camaros, and all preceding Camaro / Firebirds needed. They came up with a tire and wheel package that worked for the car. Would you not also agree that the heavier and more powerful ZL1 works better (is well balanced) with the tire / wheel combination that is on it, or do you also feel it would be better with the 1LE package? From your comments, I believe you feel it is set up right for its weight / HP combination. And as far as asking engineer Al, I was joking. Lighten up! |

The 19" fitment drops the Camaro a full inch on the bottom. That brings parking barriers, some ramps and pot holes into contact with the front fascia and some time the side fascia. If you are used to driving a very low from the factory car or a lowered car it isn't a big deal. For those that drive more typical height cars the learning curve can be expensive. |

Will a P295-35 20" on the stock 10 wide rim clear the strut on the front of the 1LE ? |

The 1LE has the standard SS aluminum rear with 3.91 gears
The ZL1 has a larger iron rear with a diff cooler. IIRC it has 3.75 but that sounds wrong some how. The auto has something different gear wise.
