I notice a massive sound improvement on Rin Hoshizora's 1998 R390GT1 LM on Spec II Mod Gran Turismo 6! Without Spec II Mod, Rin-chan's R390GT1 LM 1998 sounds like food blender, but with Spec II Mod, its sounds much better and its very much the closest to real life counterpart.
Along with these: 2008 Furai Concept, 1999 Ai Miyashita's V12 LMR, 2003 Rina Tennoji's Pescarolo C60, 2022 NASCAR GEN 7 Cars, and 2023 WRC cars like Yaris GR WRC.
@@GTGameCarsinterestingly, Rin Hoshizora and Maki Nishikino (2 members from u's and also from duo unit of 4to6), both loved Rin-chan's R390GT1 LM 1998. Its sounds like real car too when GT6 Spec II Mod was applied. Without it, its sounds the same like the one on GT PSP.
