the last time i cal them,,its a single piece.(2 piece-each 1.5mm).the thing is no ready stock for v6tt.got to order..bcoz custom made...so u can choose ur size..etc1.0,0.8,1.2 watever ur need..the thickest is 1.5mm.aik betul ka danz single piece,tu hari i tgk 4 pieces ja.... welded together
correct me if am wrong,maklum la budak baru blaja hehehe
to boost higher,,u need more than thicker metal gasket...ie..forged piston(as mentioned by danz),stroker kit and blah...blah...blah...so if u plan to bost just by changing metal gasket,,think again...there are many other things to consider too...hmm worth it or not guys to change to 1.5 mm. sounds like it can cost you up to 3-4Ks . What i know we use thicker metal gasket so that we can boost higher 1.5-2.0 bar rite? if not using that kind of boost range might be a waste then since it's expensive.i would go for another choice hehe.
