I have 1.12 bars installed and also a modified torsion crossmember from my 6 speed install. They are holding up fine but I haven't taken the car to a track yet.

I also feel that my car is undersprung compared to the race cars that were at the shop because when I grab my cage and shake the car it still wobbles a bit. When I did the same thing to an E36 M3 and a Honda CRX racecars they were both rock solid no wobbles at all. I may try my shocks on the stiffest setting to see if it makes any difference

Plan to lose weight off the front end so I will stay with the 1.12's for now
