65 fastback right now body metal is mostly stock. i really wanted to keep the cars interior apperance stock looking. so im steering away from a cage. my friend is a master fabricator if a cage is a must he will custom make a 4-6pt stainless cage that should not be in the way too much. car will be mostly used for show and street driving w/ occassional race when one presents itself hehe. it is a street car, i wont be using slicks or dragradials, so it wont be subject to hard launches. i need the body to be able to handle 650-700 + hp and i have no idea what brands styles of subcages work well and what ever mods are available. all metal on car is new, frames, entire floors, wheel wells, rockers, trunk torque box, etc. car is as solid as new (or better). i read that adding front torque boxes helps. i need to get this figured out before car gets painted (any parts welded on car will be media blasted n painted with car) i see alot of aftermarket out there. also will be using solid motor mounts and urethane trans. the tcp complete kit looks nice but look like it may interfere with exhaust. what about the maier racing subs look really long and weld to multiple points on both ends of frame. who has used what and how does it work ?
thanks for any input

Mustangs Plus does sell a chassis strengthening kit that helps prevent body twisting and flexing.



Mustang Parts from Mustangs Plus :: Sheet Metal :: Chassis Strengthening Kit :: 1965-68 Coupe/Fastback Chassis Strengthening Kit

You can also get a Monte Carlo bar and some sub-frame connectors from them for additional support.

i have the competition engineering bolt in sub connectors, which are welded in, and i can say the were worth every penny i spent on them...there was a thread some time ago, attaching a lever to the core support, and measuring the body twist before and after installing a set of sub cons, pretty convincing stuff! in my opinion, you cant beat it for 100 bucks, and a couple hours time.

Export brace and a welded steel rear seat/trunk divider will improve the torsional stiffness dramaticall for very little cash.

They are the best bang for the buck.

they are almost as bad as the fox body cars when it comes to chassis flex.

this is a good start, but you will also need the center cage that total control products sells, as well as either stringers or sheer panels, or both to connect the subframe connectors to the inner rocker panel. these mods will really stiffen up the early chassis, and if you add a roll cage as well, so much the better.
