rear anti roll bar dimension ?

I have in my 7 no rear anti roll bar and will now retrofit one. The question is, what dimension would be the best?

Actually I have in front a wide track suspension with 9/16” anti roll bar and nitron shocks. Rear as well nitron shocks and, as I said, no anti roll bar. Should I chose a rear bar with 1/2” size or 9/16” size (like in front)?

My driving style is sporty, with very rare racetrack visits.

Our car had a rear ARB. We removed it. On the road, it is so much nicer to drive without the rear ARB. With it fitted ... on a bumpy curve ... if one wheel bumps ... the ARB transmits the bumps also to the other wheel. Without the rear ARB ... if one wheel bumps, the other side stays on the road ok.

I've tried with and without a rear ARB, and prefers without the rear ARB!

My previous car had one, my current car doesn’t. I prefer it without for road and track.

Apparently many racers disconnect it for the wet.

In Name off Klaus, thank you for advice.

So no ARB @ rear.
