my oem 27mm rear bar was broken when I got the car. put a 25mm on it for the time being several years ago. just got the Steeda 27mm HD bar installed and put my rear bar on my son's v6. that really helped his out alot. still need to put the cobra front bar on his. also got him hooked up with new wheels/tires. gone are the 16" 225x55x16's and now he has a set of LMR wheels I got on sale, 17x9 with 255 40's on the front and 17x10's with Mickey Thompson 315's on the back, he is lovin it. friends tell him it needs to be dropped, but he has it even worse some of the places he goes with speed bumps so not sure what we will do. I can get a set of lowering (Eibach I think) springs for free off of my friends 96 cobra who went to coil overs. we shall see.
