But..out of curiosity,how did the frontera one's cope with boost pressure?Did you run high boost pressure through them because id imagine they wouldnt be designed to take much more that say about 10psi?

Honestly not having a pop here,just interested bud
Cheers

Ive got a GRS and it works really well.I dont think you could go wrong with either Pro-Alloy or GRS.They both get good reviews!!
