I'd love an R33 GT-R, I think they look cool (pumped guards FTW), plus Gran Turismo memories. They are also better engineered. But R34 is the dream car, now it's at dream prices sigh.
Anyone wanna swap R32 for R33? lol
Funny I had the exact problem when I swapped my stocker BM50 for a HFM BM57. No fluid going out of the rear calipers (I "bench bled" the new master and it pushed fluid out all ports). So yeah, check your master.
As usual, it's more complicated than it seems. 32psi is for putting around town with your family. I recommend 36psi for daily drivers, I run 38-40 depending on season/weather/tyre.
Cheap tyres generally need at least 40psi to get some grip out of it.
