What cars (ie years, models) are the 34mm DOHC front sway barrs on?
any twin cam vert cutlass will have the 34mm front bar as well as the highly coveted STB. Honestly if you have a TGP the one you have in there now is good enough, it is really a lot of work to get those in and out, I put one in my 88 se and it helped a ton but TGP's handle pretty well from those I have driven.
I'm pretty sure most TDC cars got them around 93ish like a Z34 or whatnot, but I just bring my calipers to the yard and measure them now.

all LQ1 cars got them
I don't think anyone has proven which bar is better than the other as far as handling is concerned. 30mm solid is what the TGP has, the 34mm bars are hollow. The 34mm bar would offer some weight reduction.
