Nismodealer Posted November 30, 2012 Share Posted November 30, 2012 Since I decided to build a rotisserie and go over the car with more detail than originally intended, I figured I'd see what other suggestions there may be for the shell. So far: 1. Seam welds 2. Roll Cage 3. New larger frame rails 4. Holes drilled into inner fenders - I've heard these cars have issues with the front end floating at higher speeds This is a road race car with a powerful 302, obviously needed stiffening which should be handled, but I want to make sure I'm not missing anything.

JMortensen Posted November 30, 2012 Share Posted November 30, 2012 I'd suggest you post up your cage design before you start welding it in. Just take pictures and draw it out in paint, or use the chassis dimensions schematic which I think is in the downloads section. We have some pretty smart guys here who have some nice cages and might be able to help get the design optimized. Are you running in a particular class, or just a track day car? I'd think venting the hood would be better than putting holes in the fenderwells. Depending on the cage you might even be able to take out large portions of the fenderwell in addition to hood vents. Is this going to be driven on the street too, or trailer only? Have you seen 74_5.0L_Z's car? It's not a bad place to look for ideas...

Nismodealer Posted November 30, 2012 Author Share Posted November 30, 2012 Derr, yes I forgot to mention the hood vents. I wasn't trying to re-invent the wheel, so I stole this cage layout: http://forums.hybridz.org/index.php/topic/106109-series-1-240z-roll-cage-build/#entry992661 Thanks again BTW Rob It'll basically just be for track days, but in case I decide later I'd like to take it up a notch I'll have the option. I don't know how I managed to miss that member. THANKS! Quote Link to comment Share on other sites More sharing options...
helghast7 Posted November 30, 2012 Share Posted November 30, 2012 From what I've seen and read about the chassis, the float is most likely coming from lack of downforce in the front end, a cheap and simple idea might also to install front canards into the bumper to help push the front down end. I know when I had my FD I used to get a little front end float at around 120 but once I installed the front lip it went away. Just a thought to consider at the least.

zohanisback Posted December 3, 2012 Share Posted December 3, 2012 Wow... That build thread with the roll cage is spectacular. Makes me realize how much I have left to go! Gonna have to bookmark it so when I get to that point, I'll have the information. As far as the original post, I was also gonna do just what was needed, and now I am stripping it down to just the shell. I will feel better knowing all the parts are new and everything is perfectly restored. I am also opting for a rotisserie with my car. I think welding in a roll cage on a rotisserie would also be easier since you can cut the floor out for the cage, then flip the car sideways and drop the cage further through the hole and weld the top of the cage. Glad I stumbled on this one. Quote Link to comment Share on other sites More sharing options...

zohanisback Posted December 3, 2012 Share Posted December 3, 2012 You never finished posting pictures of it up! It looks so amazing though. How did you do the cage by the door? Quote Link to comment Share on other sites More sharing options...
robbs70z Posted December 3, 2012 Share Posted December 3, 2012 Took a break on the car. Had my second boy and bought a new jeep. So built the jeep this week i am starting on the cat again. So more pics will follow very soon Quote Link to comment Share on other sites More sharing options...
