I finally found out how important it was to have front travel in order for the Cal Tracs to work. For years I messed around with rear ballast, hard burnouts, low pass numbers before requiring slick replacement, etc. After chasing traction (again) for a half season, I finally made the effort and cut another full coil of my drag springs, bought 28" front runners so I had ground clearance, and headed out for a friday night street legal. With no track prep, mild burnout, and dead slicks (9x29.5 M/T bias) the car packed the front end nicely. The 60' times were crappy (1.55's) showing the poor tires and track prep, but the consistancy was there. For the last race day, I pulled 90# of ballast out of the trunk that I had been running for seasons, pulled the exhaust off, mounted fresh slicks, and promptly ran a 10.622 with a 1.422 60' time, best the car ever went. This was on a non prepped friday night track. I later improved my times running the equivalent of a mid 10.5 that weekend. (timing system failed, had to run 1/8 mile portatree system) I also ran 3 rounds of elimination back to back within a .006" second grouping.

Wow, sorry about the horn tooting. To sum it up, I went from about 3 inches of front travel and traction issues, to 6 inches of front travel and a very happy setup. I have an inch between new compression stops to the lower control arms.

Some vid of the car the last race day:
