I recently got a hold of a shell, roller coupe. I’ve been buying parts for it to restore it. I want to work on the suspension & I know I want to do a irs swap, don’t know much about them I’ve read and done some research. “03-04” for good power & 3.55. The part on where I’m stuck is coilovers, brake upgrades. I’m going to do coilovers don’t know if I’m suppose to buy a rear cobra struds & also mines 4 lug, I know I have to upgrade on the brake lines, but changing to 5 lug what kind of brakes do I order fox brakes or cobra brakes? Any tips or help would be appreciated. Thank you for reading!
