MY First impressions of the underside of the HellCat was WOW this looks weak. Unibody construction as all old Mopar muscle cars. I just figured that with 707+ HP the HellCat would have some extra bracing. But no its just the same as a 6 cylinder challenger. I have seen a few kits from Petty that look good. Has anyone else ever purchased one of these for their SRT8 in the past or has anybody put some on their HellCat?
