Gents,
I already have purchased Mad Dogs GT steel reinforcement panels for the wheel well and surrounding area. I am seriously considering purchasing the Longs reinforcemen panels as well and “maybe” the trailing arm kit. Gents, what do I really need? It’s gonna be a street car for me but I don’t want to short change the build. The trailing arm reinforcement has been hotly debated here in the past. ANY input from people here with direct knowledge would really be appreciated. My car is at a
Spot where now would be the time to do whatever I end up deciding. Power will be and LS1 with possibly a mild cam. 380-430 HP ish.
Thank you very much,
Brett

All 914's need the longs reinforced.

400hp or more importantly the torque needs really nothing else, your not going to rip the body up on the street, you'll just spin the tires or go... The chassis isnt going to "twist"

Personally I think the following is necessary for any 914 thats going to be driven hard.

1. Long reinforcement
2. Rear suspension ear reinforcement + brace
3. Outer trailing arm reinforcement



I dont think the "GT" kit does anything except for the outer trailing arm reinforcement.


I think a bar from the front trunk firewall to the front suspension front mount is important in the long run for conversion cars due to the cutout in the wheel wells, but after 15 years I still dont see any tearing and mine are ugly...


Also one last thing to note, the biggest thing your going to notice is if you actually cage the car... That is a serious night and day difference in the way the car feels.

Yes the chassis will flex. I have a 4.0L 964 engine and I broke the left rear top catch in two due to chassis flex. It actually snapped the part that bolts to the top into two pieces. I have a Brad Mauyer kit and a GT stiffening kit on my car. My solution is going to be to put in a bolt in GT style top with the steel cross bracing.
