ET35 and 8.5 won't fit. Think ET44 will be max. for 8j (and ET46 or higher for 8.5) at least that is for Cupra.
Someone told me that the FR and lower allow lower ET (approx 5 mm, but I never tried)
My Cupra has ET50 BBS CH026 with 8j and 235-35-19 and I once tried and max. 4 mm of spacers will fit (before the wheels will stick out of the arches).
