its a 10, and it hits pretty nicely in my hatch. and yes melt, no hx rims. my old boss bought this car a few years back with some ugly ass 16's on it and altezzas and what not. he ended up selling the 16s and putting some nice 17 enkeis on it that ended up going on that white gsr integra that came to the modesto meet way back. these rims are what came on that white gsr when he bought it. soon my 16s will be on it though heheh.
