i really dont other than what Torquemonster had written. Heffner did say it was the only car he has ever been in, that in 3rd gear he had to let off so he didnt run it into the wall. as you can tell from the reports, the traction was limited at the track. my car should have low 150 mph's in it, but until it is done, i'm proud of my 148.8. the trans problem didnt happen at the track, it just became evident at the track. heffner was having problems shifting fast, and especially getting into 3rd. around town, we never had the problem (i drove my car last week out in MD, and it drove fine), but when it came to the track, it was a whole other story. the half shaft was the first to break, on the firt dig. of course, the titanium unitrax shaft failed. i am going to swap them for HDs, b/c i have had no success with the titanium. i will talk to heffner at lenght tomorrow, and if i hear anything else, i'll report here. i was in Vegas over the weekend, so i was out of the loop, and only know the basics. thanks for the interest!!
