i was just wondering if there is a beter rear sway bar you can put in a itr or is 24 mm the biggest ? if so what else can i do to tighten up the back end of my car
i have lca's and lower tie bar + stock lower bar

 

Are you still on OEM suspension?

Increase the rear spring rates, give them a bias over the front. Choose a swaybar accordingly.

I run GC 350F/450R with Koni Yellows and the OEM ITR swaybar compliments this setup just fine.

 

There are several options for bigger rear sways. Search for "swaybar" or "sway bar" in the ITR or RR/AX subforum and you'll find everything you need. Unless you can give me a reason not to via PM, I'm going to lock this.
