been awhile, gent!
I have DG springs with neuspeed RS10 18x8 and conti extremecontact dws06+ 235/40-18, also FSB and RSB on my 2017 GTI S manual. Car will never see track days, I just want something comfortable, so should I look into B6 or even B4? (not sure since DG isn't stock but not exactly...
I have S trim, so no Fender, no Helix sub, so I bought a used one had it installed, then the rear set quit so I replaced them with JL C2 set. I can't tell the differences in sound, the biggest dif with the sub is fold down your rear seats lol
another inexpensive short shifter option is Boomba adapter, used one is pretty cheap, and probably take your mechanic 10 min to install (you can DIY as well), I found it very comfortable and balance
I don't know if anyone knew this already but the bass is so much better with the rear seats fold down lol
I got new wheels the other day and had to put the rear down, hence the accidental upgrade :D
