And you offer this special advise because of why? If the battery moves back that far I would say the car will have lots of problems including the wire harness that is routed under the battery. The Rod Davis radiator is going to feel the hit too.
Sorry for your trouble. A lot of guys moved the battery to the trunk for other reasons. I guess the main point is not with run into anything with the car and you don't have to worry.
I'm not too worried about the catch can in an accident. The stand alone fuel cell for the nitrous system in the same general location is a different story
Mikers crash was an extreme offset crash plus the car in front of him was braking heavily causing their bumper to rise up and Mikers front end was down due to his braking. The car in front's bumper completely missed Mikers bumper bar and the impact drove his headlight back over a foot, partially dintegrating it. The battery was next to be hit, then the catch can, then the valve cover. The upper radiator crossmember is smurfed as well.
Car looks repairable every panel except the left front fender and hood is perfect.
This is good news man, glad to hear it. So when you see olde guys like me on your next volunteer driving instruction blitz, running "Two Seconds" at speed behind the car up front, you know why.
Yes, assholes will take up that space in traffic, so you just back off and run two seconds behind them.
Memo: This does not apply when tailgating Napalm's G8 on the Dragon, because you can trust him not to be a tard and slam on the brakes.
