Commodore’s Garage #30 – A Whole New World

December 15th, 2017 by Matt Holden

Did anybody else notice we have a new build?  I know, it’s a surprise to me as well. This year has been a year of major updates to iRacing’s stock car platforms, and we got a pretty big one right at the end.  To look back at this same time last year and think about … Read the Rest »

Commodore’s Garage #28 – The 2016 Class B Champion

August 11th, 2017 by Matt Holden

Setup details at the top of the sim-racing ladder are a closely-guarded secret; we all have experienced it at some point.  Earlier this year, I had a conversation with the crew chief of the car that has won a few recent NASCAR Modified championships about chassis setup, and he willingly gave me the spring rates … Read the Rest »

Commodore’s Garage #25 – Bumpstop Contact in Telemetry

June 16th, 2017 by Matt Holden

Last week’s build release put a stop to the coil-binding trend in the Class B series that had become widespread across the front-running cars.  Eliminating all front springs below 500 lb/in took us away from binding by simply eliminating the springs that could bind under normal conditions, placing everyone firmly into the bump spring setup … Read the Rest »

The Commodore’s Garage #2 – Step 1: Grab a Pencil

August 4th, 2016 by Matt Holden

“We learned how to make them loose, now we need to learn how to make them fast.”  Mark Martin said this during a post-race interview after an Xfinity Series race a few years ago and it’s stuck with me ever since.  It’s a simple quote that largely went un-noticed, but carries so much information that … Read the Rest »

Behind the Scenes: The NASCAR iRacing Series powered by iRacing.com – Find Your Own Way

June 14th, 2016 by Matt Holden

The incompatibility between multiple drivers and setups is well documented in the real world of motorsports.  Almost everybody who’s been following NASCAR for a few years knows that Denny Hamlin and Kyle Busch might have very similar cars, but Matt Kenseth’s car is probably very different.  A few years ago, even during the toddler years … Read the Rest »
