Cutting the crumple zone during a dash lift.

Hey guys, Two questions.

First: Is it necessary to cut the crumple zone before doing a dash lift?

Second: I was wondering if anyone had any tips for making the cut to the crumple zone, what is the best technique for removing the fender to gain access to the crumple zone?

Thanks

We don't cut the crumple zone. We just cut the bottom of the A pillar where it connects to the frame.

If you want to remove a fender, perhaps an air chisel?

Its not necessary to cut the crumple zone but if you have to lift the dash alot it will make it easier. If we do cut it generally we peel the the fender back with the spreaders then make 2 cuts to the crumple zone to notch it out so it has room to move.

Be sure to look at the strut tower placement to decide if you want to do a roll or a dash lift. The placement of the tower against the firewall can really hamper your roll, and hence a lift may be better. If you are going to lift or roll and need a good lift or roll in my opinion you will reap the rewards of spending a couple of moments to make a couple of significant relief cuts first. Teach a lot of classes and have tried it both ways, and have conme to the conclusion that it is nice to give the metal somewhere to go, otherwise it will go where IT wants to go...

Cutting the upper rail, aka crumple zone, does improve the potential success of lifting and rolling the dashboard. Worth the effort/time.
