Do I need flexi/cut arches?

Looked on search but can't find my answer. Basically I have 265/75 16 insa turbo special tracks on std alloy wheels and a two inch lift. I have a set of 30mm spacers to fit but not got arches yet as I'm fed up of the rubing on radius arms even with lock stops fully out. Basically can I fit spacers b4 I fully cut arches or will I come home from offroading tomorrow with no wings left. I've also already done a camel cut. Cheers in advance guys

Around 2000, I was forced to remove a set of 30mm spacers from my RRC half way round a P&P course because I'd not chopped the arches.

I've basically the same spec- Insa Special Tracks, 2 inch Lift, camel cut plus a bit more.

Front wings and rear arches are now pretty well destroyed and that's without spacers.

Only way to know for sure is to give it ago. You'll soon find out.
