Although I'm in a GC chassis my towers are just as close to the firewall. After a lot of driving with and without the bar I am keeping it on. I wouldn't exactly say this is the first suspension mod to do to your car though. I've got a pretty stiff setup so it makes things more aparrent for me. Just thought I'd toss in my 2 cents
