Jeremy82zx Posted January 6, 2009 Share Posted January 6, 2009 Made out of hot glue and toothpicks lmao. I know it isnt proportionant or anything. But i do plan on doing this to my s130(with tubing not toothpicks). This shows my tube placement. Basically im just looking for ideas to improve on my design. more supports in the upper half of the main hoop? Rear strut tower supports?

The love of JDM Posted January 6, 2009 Share Posted January 6, 2009 Dang you had me fooled lol but sweet idea to make them out of tooth picks! Not sure if I could help you on improvements tho. Quote Link to comment Share on other sites More sharing options...
cockerstar Posted January 6, 2009 Share Posted January 6, 2009 You're going to want to redo the door bars so you can get in and out of the car. With the tubing you will be able to utilize bends and make things much smoother I haven't seen someone tie the front struts into the frame rails by the firewall like that before. I've only seen it through the firewall and to the dash bar. I would also tie the front of the strut support in with the front most bar so there is only one point in the engine bay mounting to the fame rail. Take this all with a grain of salt, because this is just coming from observations of others tube frames and cages. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted January 11, 2009 Share Posted January 11, 2009 the front looks exactly like mine.... still working on it though.... Quote Link to comment Share on other sites More sharing options...
SHADY280 Posted January 16, 2009 Share Posted January 16, 2009 your front looks o.k. id be a little concerned for the rear, it has no support other than horizontal. if a large bump was hit could it therotically move (bend) upwards. could use some extra tube running to the main hoop? im no cage designer, just a looky loo Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 16, 2009 Share Posted January 16, 2009 Get the book Chassis Engineering by Herb Adams. He does a lot of modeling like this but he uses a little stronger balsa wood, and then the tests the torsional rigidity of the design. You could do the same, but you'd need frame rails and I don't think the toothpick joints are strong enough. Your rear tubes look like they go all the way back to the car. I'd suggest that is a bad idea and that you should make them attach to the shock mounts or something else closer in so that you keep the crumple zone in the back and if you get rear ended it doesn't junk the whole car.
