Reinforcement Bars (Thanks to Naoki)

Megan C-pillar bars for DC5 fits our M30s


(note: the megan c-pillar bar for the s13 also works if you swivel the threading down completely on each side.)

Strut towers fit but you will need to remove the adjustable nut on both sides.
The strut tower bar I am using is a cheap knock off. Not sure if the other brands will fit by removing the nut.
