chassis certification question
 

i have a 95 spitzer red i just had it recertified and they checked the 2.7 what is the dierance in it being a 10.1 or 10.2 or 10.3 or 10.4 i know i am certified to run 7.50 or slower but are the 10 ratings better or the 2.7 better i cant find any info on this

Its spec rule for sure as you knowe..like the "Funny car" cage is 25.1 certification...
you will not be able to pull up any SFI spec book on-line because of the trademark rights..there are several guys on here that could answer the question more in depth..Ed ( mcracecars) could help you answer any questions on this issue i am sure.
