Is it better springs, dampers, ARBs?

Seriously......

Front ARB - Same as standard across F20 range. Interestingly, same as 435i GC too.

ARB Swing Support - common part across a lot of F20/30

Rear ARB - For m135/235i models only

ARB Swing Support - common part across a lot of F20/30

Dampers seem model specific (no spring rate info)

Front Brakes - Caliper and disks are common across F20/F30's

Rear Brakes - Caliper is 135/235i specific - Disk is common across F20/F30's


Differential - 135/235i models only

Gearbox - 135/235/ - also same part as 6 Series (petrol) and 7 Series (petrol)

Steering Rack - common across F20/F30 range



So to summarise; in what makes the M235i "special" is.........

Rear ARB, Dampers and BADGES.... lots and lots of M Badges

And perhaps most important of all, what resides under the bonnet (which is just about to get better still!).

Some baseline by the Jb4 guys during beta testing Jb4 on B58, it seems the comment is more or less correct.

JB4 "opens up" the upper rev range more so than EWG N55 as B58 is holding more boost longer higher up the rev range than N55.

I have Jb4 stg 2 on ewg M135i and the difference up top is noticeable between switching JB4 off and on to one of its absolute maps. B58 will be even more of a scorcher no doubt....
