Engine Choice -- If the LS7 is available at a reasonable price we use the LS7, although a LS3 with a GMPP cam and tune would be good too. My bottom line is we need 500 NA at the crank, or more What I really want is 500 NA at the rear wheels. That means 550 or 560 at the crank. That also means we need heads to go with the cam on the upgraded LS3. I am not sure what it would take on the LS7. I'll accept 500 at the crank, but I would be a drooling idiot with 500 at the rear wheels. LS7 or LS3 doesn't matter as long as we are in the RWHP minimum range of 430. Weight Reduction -- Everywhere we can from reduced spray in sound insulation - cloth non-power seats - fascia - console - wheels - brakes - exhaust - can you use less paint? No sun roof. No back up camera. The focus is on performance. Wait a minute. Can we replace the side view mirrors with a video display for less wind resistance and the same or less weight? Wheels and Tires -- You can probably guess 19x10.5 lightweight wheels with 305/30/19s Gearing -- The smaller rolling diameter wheel and tire package address the gear change, but we'll ask the engineers at Chevrolet to fine tune the gear box ratios for optimal performance Brakes -- CTS-V / ZL1 calipers with the of the shelf GMPP Brembo two piece front rotors to improve breaking and reduce weight and don't forget the brake ducts Exhaust -- Titanium borrowed from the Vette. A little more aggressive in tone. This ain't no panty waist machine. We want an edge to it. Hood and Fascias -- Keep it simple, clean and light. If it doesn't reduce the drag coefficient or add down force it doesn't go on the car. Cold air induction is critical. Thermal Management -- The LS engine do not like heat and they are furnaces. Lose the sound insulation above the plenum. Lose the engine cover. Lose the hood blanket. Add heat extractors. Coat the cast iron manifold inside and out to reduce heat transfer. Add oil and PS coolers. Can we increase the oil capacity with a new pan? Maybe add a few baffles? Don't forget the diff cooler. Driveline -- We want the revised ZL1 drive-line since we plan on abusing, err driving this one Change out the lube in the OE CV joints so it doesn't liquefy when running hard laps to a higher temp lube. Suspension -- Forget the typical OE conservative understeer bias. We prefer axx happier The suspension has to be Pedders Supercars with independent bound and rebound adjustment. We'll address the adjustable ride height with special locking rings that require a special bow-tie track spanner to unlock them. The special bow-tie track spanner is for off road use only In addition to the new revised sub-frame bushes that started in January, we want to add Pedders sub-frame inserts. We'll also use the EP6579 full face radius bush inserts. Pedders extended range alignment bolts are direct replacements for the OE bolts and provide a greater range of adjustment to suit the use of the car. These can all be integrated into the line process. A little trickier are the Toe link bushes. I guess GM will have to ship the OE arm to Pedders and we'll return them with our bushes. Allow me to compliment GM on the ZETA II. The arms are good to go from the factory. They do not need replacement. The arms just need a little assist from Pedders Steering Wheel -- I love the CTS-V wheel. The ZL1 is close to the CTS-V. We want a wheel with Alcantara for grip. I could care less about the controls on the wheel. Gauges -- We need real gauges and not simulations of gauges. The oil temp must read from an oil temp sensor with an accurate reading. Warranty -- We are asking for a lot of performance at the best possible price. I for one would be happy with a 24 month / 36k bumper to bumper. I don't expect GM to cover what I am asking to be built for 100,000 miles on the drive-line. There is a balance to be reached. Deliver me a car that works well. Allow me to beat on it, not run it into the ground, but use it as it was intended to be used for a reasonable period of time. i.e. I was running laps at Harris Hiils. My CV joint failed. Cover my CV joint and allow me to be honest. In exchange I'll take a shorter warranty period. We have a Z28 that is a very different car from my wife's ZL1. It should sell well and compliment SS and ZL1 sales, b ut that is just my opinion. |

OK... to Pete....
But Need more colors........ but I Think I'm in on all the rest... what about AC? radio... etc??? you leaving all that in? and I noticed you say to go with adj coilovers.... No Mag ride for the Z28??? and Ti exhaust??? really? seems a little over kill and expensive... What do you think a Z28 price point should be??? and no... not what you would be willing to pay for it...

You can save pounds with a titanium exhuast. Saving pounds on exhuast is cheap weight savings even with titanium compared to any body panel, sub-frame or arm changes. No HVAC turns the Z28 into a club racer and limits volume to a handul of cars. That means the HVAC and radio stay. I knew colors would be a point of contention. If we only offer the Z28 in two colors we create a stronger identity for the Z28. Two special colors. Available only on the Z28. Price point..... $45,999.99 |

So I'm thinking the price needs to be below 40K... Having said that... I'm always amazed at how expensive weight reduction is... I think that is going to be the most difficult hurdle to clear... I like the idea of stripped down.. but I don't know if the price point will support that amount of real weight reduction... I say go with as many suspension components as possible. Remove the fluff, leather power seats (I get the AC and Radio requirement and I agree it should be there.) very simple stereo with less speakers and so on... and try like hell to keep the price down. If, the buyer wants to pay the aftermarket for lighter stuff... then so be it... we've pretty much proven that Camaro owners are spending large sums of money right now...

I am guessing we have real money costs to build the Z28 of 5 to 7K. that brings us to $38K, but Chevrolet has to make money on it so we double it $31k + $14K = $45K. Maybe they can build it for less, but I would be shocked if it were less than $40K. |

So we take the LS7 with a full warranty. Damn I hate when that happens I'll take the weight savings on the exhuast along with the bill. So when can I place my order for Serial # 427 |

Don't limit the colors and make all stripes options. I need my Victory Red with white stripes.
Let the buyer decide what options should be on the car. If someone wants a stripped race car, order it that way. Pete, I'll get my #28 before you get your #427.

Wow, I love it guys!
I go away for a little while and we are in it up to our necks. Hey Number 3 I think the excitement is back!!! Pete I'm impressed with what you've put together. A stout 427, bulletproof drivetrain, brakes from h**l, wheel/tire combo for grip/less unsprung weight and a track-like suspension. If we can get the pricepoint $42K - $43K I think we're there. And, I fully agree, I want a decent stereo and living in the south you gotta have AC. But for those hardcore guys this can be stripped, by them. Go ahead and allow for some options, but Pete I'm with you keep it simple. As for colors and such this car has to be easily recognized as a different and special Camaro, Yeah a Z28. |

The LS7 enjoys a full powertrain warranty in the Corvette, why would you expect any less in this mythical creation we are concocting via internet conjecture?
