RS4 DRC delete & ARBs

Hi folks,

I have a 2014 RS4 and have removed the DRC system for coilovers. However, when I was researching ARB info and I confirmed this personally, the RS4 only has a 16mm rear bar as the drc compensated. Lesser A4s have 19mm or 22mm rear bars. So, my question is, is a arb upgrade really needed now the drc is gone? 

I feel it must be as I have piddly rear bar at least, probably front as well although ive not measured that yet. So I'll be getting more roll than an SE spec A4 lol. 

I guess the coilovers is a factor also though so Im not sure.

I did search btw, plenty on arbs but not in relation to drc delete. Apologies if it has been discussed.
