RideTech should have a rear bar that would work too. If you go that route, I'd get their front bar to match.

The Hellwig One Lap Camaro rear bar is not listed in their catalog. We did not use the 5824, it was too light. You would have to call them and ask about it. It is capable of adjusting to be very stiff at the stiffest setting because we were running a 255 front tire and 335 rear with air conditioning & dry sump up front. It will also adjust to a fairly soft setting because it has a very wide range of adjustment ( lots of holes on the arms).

My hunch is, your rear suspension has a higher roll center height and won't need as much rear bar as we did on the One Lap Camaro, but I don't know for sure. With stock control arms, you should be able to run a 255 front tire on an 8" rim. We fit a 275 but had to run the Speed Tech high clearance upper A arms and limit turn angle. You won't be able to get the optimum amount of positive caster with stock arms, so will have more understeer from that. Ride Tech managed to fit 275's in front on the 48 hour Camaro & retain pretty good turn angle.
