phr mustang II pulled .99g????

[one+g]

Just picked up latest phr mag and it has a blue mustang II with modified factory suspension and like 225 rear tires but all out race tires. I can look back and get the exact details but this seems alittle far fetched to me. I mean an Iroc pulling .90 and this car with less advantageous design ( but race tires pulling .99 avg.? Anyone read this? What do you think? Any of the modified cars on here put a g- meter in and tested their rides?
