Rick, Just kind of wondering why you went with a 25.5. Does your track require it or do you just like the added security? Or do you plan on ripping into the 7's? Also how much weight did your 12 pt add?
Went SFI 25.5 since I was going NMRA Drag Radial racing and would have been knocking at that door...8.0's was the goal I honestly don't know what the cage actually weighs, the Pro-stock style backhalf I did is not required by the spec but after talking with some other chassis builders I felt it was needed to help make the car hook on the radial.
25.5 Full Bodied Car Stock or Modified/OEM Floorpan and Firewall with OEM Frame or Uni-Body Construction – 7.50 to 8.49 Seconds; 3,600 lbs. Maximum
Ive also looked at updating to The new SFI Spec 25.3 for Full Bodied Cars, 6.50 to 7.49 Seconds ET, 3,600 Lbs
Really at around a 3400lb race weight I just wanted to feel safe...
