Well, I ran my first 1/4 mile last night (5 of em actually), and all I can say is....HOLY FREAKIN WHEEL HOP BATFRIENDS!! Sheez, I mean I have read all about the wheel hop issue on IRS cobras, but this was ridiculous. First 4 runs, I bounced down the track and couldn't do better than 14.2 @ 102mph. I know this was my 1st time running on a track, but somehow I expected 13's. So after my fourth run, one of the other drivers approached me and told me that I was losing as much as a sec due to "that horrible hop" and that I needed to get some ET streets tires or swap out for a solid rear axle. He also told me to granny shift or I would snap a half shaft! On my fifth run, I shifted like I was goin' for groceries and expected a 16 sec time. It turned out to be my best run of the day, 13.7 @ 104 with a .560 reaction time! I can't help but wonder what the car would do if it could hook up. Does anyone have advise for the wheel hop issue, and are those tires a good place to start??
