thats matt robinsons' car he is a frequent member on this site, indeed a badass ride, that car was raced in nascar and he redone it from top to bottom he has a team/crew and all..travels all over for racing and has a plethora of auto racing knowledge in his head!
The car has been completely overhauled since those pictures were taken in 2004. If you go to www.robisonracing.com you can find numerous images from the overahul on the "Underpinnings" page and recent images of the car at the track on the "Home" page and "2001-current" page.
I have tested the new version of the car on several occasions over the past few months and plan to race later this year.
Here is a link to a video from one of the earlier tests that was made by MERC460:
