The TeamRS decal sits over the OTT stripes and you can see the line of where the OTT stripes sit underneath it but you really cannot see this unless you stick your nose right up to the bonnet. All vinyls should come off easily with a small amount of heat applied (e.g. a hairdryer on low heat) but if you do damage the OTT stripes 1stickerboy can rustle up any part of the stripes set you might damage (stone chips, bumps, knocks etc)

The mudflaps are held on by wood screws, I think a shoelace or some string and a prayer. It is a b*gger to get them to fit on really. You'll have to screw into the lining of your wheel arch and hope that what happened to a friend doesnt happen to you (reversing up a kerb, the mud flap was being folded under by the kerb, caught under the wheel and *rrrrrrrrrrip* hey presto there's your wheel arch liner)
