For Cup, the low downforce package will debut this week-end at Kentucky. The package consists of a reduction in spoiler height from 6" to 3.5", the reduction of splitter overhang from 2" to 1/4" and the reduction in the width of the radiator pan from 38" to 25". The net downforce reduction will approach 30%, and Kentucky already had one of the most worn out, oldest racing surfaces on the schedule. Look for some of these cars to look like they're driving on ice, since some of the teams have committed virtually no resources whatsoever to doing any testing with it.


Also for Cup, there's a new high drag package that will debut at Indy on the 26th of this month and then will also be used again later on at Michigan. The package consists of the current 2015 splitter / radiator pan combo, but includes a 9" tall spoiler with a special air trapping wicker along the top edge. The intent of this package is to introduce high speed, high drag pack racing like what is currently seen at Daytona and Talladega.


The Xfinity guys will get into the high drag action at Indy as well, getting a 2" tall extension on top of the existing 4" spoiler, and also getting a super speedway style lower rear valence (dropped an additional inch from 2" to 3") to trap air underneath the car.


If anyone has any questions about any of the stuff that's upcoming, then there's no better time than the present to ask. Otherwise, fingers crossed for a great show!

How crazy was the job today with the stuff that went on last night at Daytona?

The office was mostly quiet today because everyone was still in transit coming back from Florida, but tomorrow should definitely be interesting. The officials couldn't get the 3 car to fit in the hauler, so the hauler pulled in today with 6 crates full of mangled 3 parts...but no 3 car. A separate rollback (or box truck or something) is being sent back to Daytona to pick up what remains of the car, so it will still be a couple of days before I get to see it up close for myself.


I was busy anyway, though, since there is a LOT of CAD work, rule book changes, vendor manufacturing files, etc, etc that are involved with formally releasing one of these aero packages.

A couple of small corrections / additions to the original post...


1) the high drag package to be used at Indy and Michigan will use last year's radiator pan (43") and not the 2015 radiator pan (38").


2) This week's low downforce package debuting at Kentucky will also be used later on at Darlington.
