most of them are like that Terry,
even the rexspeed ones for EVO 7/8 and for R33 GTR i've gotten through my group buy due to the nature of carbon cloth it doesn't confirm to tight/sharp corners well. i've seen people rivet it on but thats a more permanent solution as it leaves holes in the bumper
I am planning to make up a prototype for the R32 GTR in the near future but it won't be that big as i reckon it is too ugly and stands out too much IMO (unless its a dark car then it isn't too bad).
i will make it a smaller style so it sits below the tow hook, similar to the pic below.
if it turns out alright, i will get a local composite place to redo it in carbon weave finished in 2k clear.
