There's been a lot of chatter lately on which suspension to use for a S550 Mustang to eliminate IRS wheel hop and take the new S550 Mustang to the next level. The team at Steeda just announced that John Urist's wife, Melissa, drove the first factory IRS S550 Mustang to break into the eights, with an 8.906 ET. Yes, Melissa did it first and it all took place last weekend during the Street Car Super Nationals at Las Vegas Motor Speedway!
