What Cert Do I Need???

Choosing your cage is a HUGE decision! There are a lot of factors to consider, we want to make sure that you’re selecting the best cage for right now as well as for the future of your build. Planning for the future can help you save money and time throughout the course of your build. Our first priority is keeping you SAFE. Here are a few factors in selecting the best cage:

Factor #1 : How fast are you running? How fast do you PLAN to run?

Planning for the future goals of your build will be the most economical option. It can cost a bit more up front, but saves you time and money later when you don't have to take any steps backwards. An 8.50 may or may not be the best place to start. If you don't have goals of going faster than 8.50 or 180mph, then it's the best choice.   However, if you plan to run faster than your 8.50 cage allows, then you may want to look at other options. We often recommend an 8.50 cage with a 25.5 or 25.3/2 floor structure. It does require you to do the floor structure initially, but it is much easier to upgrade later. Upgrading a standard 8.50 to a 25.5 (or higher) later can be exceptionally difficult and most end up cutting out their 8.50 and starting over.

Factor #2 : Are you installing the cage yourself? What type of welding are you comfortable with? 

SFI and NHRA have rules on how cages can be welded as well as what material each cert can be made of:

  • NHRA 8.50 cert cages can be mild steel or chromoly
  • SFI 25.5 cert cages can be mild steel or chromoly
  • SFI 25.3, 25.2, and 25.1 MUST be chromoly
  • Mild Steel can be MIG or TIG welded
  • Chromoly must be TIG welded

Factor #3 : How much does your car weigh? Each cert has maximums:

  • 25.5 3600lbs MAX
  • 25.3 3600 lbs MAX
  • 25.2 3200 lbs MAX
  • 25.1 2800 lbs MAX
