I have a 98 Gt and all my problems have been small and have been aftermarket related but it is underpowered for what i have done to it because i dont have the P.I heads on it YET! If you do get it i recommend this as your first mod. I have not broken my rear swaybar on it but i did break it on my 95. As i found out last night the intake manifolds break easily (which there was a recall on this from what i have been told) when my friend broke his at Test N Tune on his 98Gt.
