916 chassis Options

[Montreal914]

Were the few 916's equipped with the GT stiffening kit?

Other than the obvious rigid roof, were there any chassis stiffening improvement to handle the larger powertrain/gearbox?

Thank you TMM914, Marty, Rory, Dave, and Bob. (IMG:style_emoticons/default/sunglasses.gif)

Yes Marty, I now plan on adding the GT kit on my build, and I have been wondering about what else to reinforce. My car will be a naro body street car, therefore no roll cage.

I wanted to start with the basics, i.e. what did the special project crew of engineers at Porsche did on the 916 being some didn't come with roll cage. The GT kit seemed logical, but maybe something else was done? (IMG:style_emoticons/default/confused24.gif)

Reinforcement of the A-pillar maybe, other exclusive 916 reinforcement mods?

Interesting to see that Brutus did not have any visible reinforcement of the trailing arms and suspension ears.

Current plan:
- Inner Maddogs kit
- Outer RD clamshell
- GT kit

Thinking potentially:
- Suspension ears reinforcement
- Inner ear heim joint rod to firewall
- Outer heim joint rod for alignment adjustment and maintain
- Rear trailing arm bulhead plate (Chris Foley's trailing arm reinforcement design)
- Some rear suspension tower seam stich welding

I might be overthinking this, but a 3.2 and a 916 box is a very different setup compared to a VW bus engine.

When I was young (IMG:style_emoticons/default/rolleyes.gif) I had 3/4" front and rear sways bar on my sleeper hot rod VW Beetle at a little lowered right height (not carzy like we see in SoCal) and with the bad streets of Montreal, I cracked the front pan (the triagular part of the pan under the tie rods area). This was an eye opener on imposing more stress on chassis.
