1250 is expensive but I'd rather have a pair of feet after an accident than not.

Next to the chassis and the side bars it's the main safety feature of the car, why would you want to compromise it with a pattern or secondhand part? You may as well just leave the original damaged one on there, you'd probably stand more chance than a part that has never been crash tested.

I'm not doubting the wisdom of your words, you have probably seen more of these items close up than most of us, but I had assumed that any damage to the box would be visible to the eye or felt with your hands if you were inspecting one?

The oem crashbox will have been made to tight guidelines and tolerances.

They are laid up in a very specific fashion in order to give it the strength and crash characteristics, that when tested, will give the same results over and over to an accepted industry std.

The copies are just that, nothing more than a copy of its overall dimensions. No thought or care will have gone into the design on how it will perform when exhibited to a crash.

Hence me saying that a damaged but original crash structure is potentially safer in a crash than a brand new copy part...

Depending on how bad the damage is you can repair the original ones if not tooo far gone.

Also, if youre having to replace the entire crashbox make sure whoever refits it takes extra time and care in preparing the front of the chassis for the new one to be bonded to. Also that they use the correct adhesive and apply it word for word as the book say's.

No good in an impact if it gets ripped straight back off again...

Post a picture up let's have a look. If it's just nibbled around the edges it's not so bad. If your into the core of it them time to replace.

Iv not got any but I'll take some tomorrow, the worst bit is the thin bit that runs down the drivers side. The core bits not damaged.

If I go for replacement I'll be doing it myself, but year would need to find the original adhesive etc like you say. I don't really like other people working on my car haha.
