IRL halts practice at Texas Motor Speedway

Practice was stopped yesterday at TMS after two G-Force drivers suffered similar high speed shunts. A right rear heim joint appears to have failed on both cars causing them to spin into the wall. IRL officials have halted practice until today to determine if there is a problem with all of the heim joints on the G-Force chassis.

Could these component failures be related to the IRL mandated spec cost chassis?

im not sure Kc as i havent been following the tech side of the series and i dont know who actually crashed but it is probably a good thing that they have decided to check all the cars out...seems rather professional to me and thats a very good thing for the IRL
