SS wheel question.

[naschmitz]

I honestly do feel that the SS classes should be for a stock car,as built and delivered,regardless of manufacturer or model.

So if Bob puts factory C5Z06 pieces on his C5, he's a stock C5Z06?

Bobs car is a C5Z06......isn't it?

I was told that I could not run the Z06 wheels on my c5 coupe because it was not a z06.

Some of the structure of the vehicle is different so I think it would be extremely difficult to update a regular C5 to a C5 Z06, but in principle if you change everything then some other organizations allow it. The COM rules aren't explicit on this.

Oh, right Bert I was thinking of Bob Brooks.

I agree that stock should be stock, but the issue remains that modern cars come with stupid sized wheels not suitable for the track. What you are proposing would prevent many many cars from running competitively in stock class. Not that there really is any regular competition in stock class anyways outside of SSU.

You're right there is plenty of competition in ST and SP, and that seems to be were most people are gravitating towards these days.

They have those stupid sized wheels because smaller ones won't fit over their stupid sized brakes. The newer cars still have a huge technology and power advantage. But the older cars usually have a weight advantage...and can find r compounds that fit their stock wheels. I think that evens the playing field.

SS rules stipulate: "No updating/backdating allowed". If it is a 2003 C5,it is required to run 2003 C5 equipment.

However.....the folllowing SS clause does seem to indicate that you can add/subtract "options"..that were available for a particular model..so if it was availabe as an option that year,which the ZO6 option was for a base C5..then options that came with a ZO6 optioned C5 Corvette in that model year would be permissible.

"Showroom Stock automobiles will compete in an "as delivered" configuration with preparations and modifications allowed only as
follows. In other words, if it’s not explicitly permitted here or in Section VI, it’s not legal in Showroom Stock. “As delivered
configuration” is defined as having been available from the factory for that model and year, or having identical form, fit and function
to the factory component. Options for a particular model of vehicle may be installed or removed in their entirety. This definition
applies whether or not a performance gain is derived from a particular modification."

So...it appears that a base 2003 Corvette C5 owner could install any ZO6 options,if they were available for that model year.

SSU only classifies Corvettes as such: "Chevrolet Corvette 1991+ NOC" Not sure how to interpret that...

At this time,it appears you could run a stock 2009-up ZR1 in SSU class..


Maybe I missed something...?

I think the C5Z is a completely different car from the regular C5. The Z06 is a fixed roof coupe and the base C5 is a hatch back. There are many other differences between the two. To completely change a base c5 into a Z06 would be almost impossible.
I don't understand that rule either and it should be deleted.

I think the intent of that rule is to allow e.g. a base C6 to be converted to a Z51 C6 (not an uncommon upgrade). Converting to a Z06 is pretty much out of the question given the extend of changes required as you said and wasn't really an "option" package but a different car entirely.

Basically you can change your vehicle "spec" provided it was available that model year. If I wanted to convert my base 370Z to a Nismo 370Z I could, although it can end up changing your class.

Yep. That makes sense. So Bob can install the z51 performance handling package that was offered on the base C5 but it doesn't include the wider Z06 wheels.

RPO Z51 Performance Handling Package (1997-04)

Original Option Price: $350-395

The Z51 package on the C5 included stiffer springs and larger sway bars and remained virtually unchanged for the entire C5 generation. Z51 was standard equipment on 1999-00 Hardtop models.

Option Restrictions: Not available with F45, F55, or on Z06 cars; automatic cars required the Performance Axle Ratio.

The ZO6 does seem to be a differend build/model,and not really an equipment "option" for a base coupe Corvette,probably similar to the difference between a Mustang and a Mustang Cobra. However,it appears a ZO6 Corvette and a base Corvette would both run in SSU...and the '09-up ZR1 as well. As it stands now, 1991-up Corvettes all appear to run in SSU unless "otherwise classified". (I am assuming that is what NOC means; not otherwise classified)

GM disagrees with you. Here's the official factory site and how they define it: http://www.bowlinggreenassemblyplant.co ... eStats.pdf A C6Z06 is "Regular Production Option" (RPO) FE4.

[breakaway500]

Actually,that list proves my point; coupes with the FE4 Z06 suspension option constructed were 0%. Same with convertibles..0%.

ZO6 Corvettes must be considered "not coupe or convertible" in the "total" on that list......so they are ..unique, it seems There were 6,272 ZO6 Corvettes built in 2006.

[betelgeuse]

According to this they are different models. Not just option packages.
