Hi guys
Recently bought an F20 m135i manual after a 3 year hiatus from BMWs and back loving them again.
I had already ordered a JB4 on the drive home from picking it up, today the intercooler and de-*** arrived and tomorrow I'll be heading to the dealers to order an M Performance diff.
So I am already looking at the next step, and I guess the question is am I correct in thinking that would be a WMI kit?
I'm interested in it for both outright performance reasons, but also because I am hoping I can use 95 RON fuel (equivalent to US 91) and still make decent enough power daily, and fill up for 98 (US 93) when I fancy a bit more spice. Purely because where I live, it cost me the equivalent of $8.30 a gallon to fill up today. 95 will take a third off that.
Cheers in advance guys
Ross
