68Datsun510 Posted June 9, 2011 Report Share Posted June 9, 2011 It would simplify the hell out of the front end, or at least i think. I beam axle, basic leaf spring suspension, spindles and hubs with disc brakes. Get all the obsolete hard to find crap out of there, ya know??? Quote Link to comment

thisismatt Posted June 9, 2011 Report Share Posted June 9, 2011 A single straight I beam with leafs? Of do you mean dual I beams with coils? Dual I beams wouldn't work properly with leafs I wouldn't think, and why give up IFS for a SAS that isn't 4wd? Quote Link to comment
thisismatt Posted June 9, 2011 Report Share Posted June 9, 2011 Okay...so, that would decrease ride quality and handling. You're changing from a fully independent suspension to essentially a solid "axle". Quote Link to comment
Ken_B Posted June 9, 2011 Report Share Posted June 9, 2011 Dude, narrowed mustang II is the way to go!!! IFS, disc brakes, power steering, all parts are easily available. Quote Link to comment
yello620 Posted June 9, 2011 Report Share Posted June 9, 2011 Why not just install the later model nissan lower control arms,custom upper arms, ball joint spindles and have averything modern and retain the IFS. It is so easy to install too. I am hoping to have the custom upper control arms available soon. Quote Link to comment
datsunaholic Posted June 9, 2011 Report Share Posted June 9, 2011 I think that replacing your ~1960s technology torsion bars with 1920s technology solid axle is not quite going AWAY from "obsolete". Other than the discs, and that's covered here how to change that. So you'd help your straight-line stopping but ruin the handling. If you're gonna go with leafs, might as well get a Dana-30 or a Toyota front axle and a transfer case. It'll ride just as rough as that model-A axle will. Just go with 720 or Hardbody suspension. It'll take the same amount of welding, but the parts are a LOT cheaper. Quote Link to comment
bananahamuck Posted June 9, 2011 Report Share Posted June 9, 2011 I drive a old solid axle truck with fatty tires on a almost daily basis, and to answer your question ...........NO Quote Link to comment
68Datsun510 Posted June 9, 2011 Author Report Share Posted June 9, 2011 Eh, 'twas just a thought =) Quote Link to comment

I beam axle, basic leaf spring suspension, spindles and hubs with disc brakes. Get all the obsolete hard to find crap out of there, ya know??? Simplicity of design~ yes. Complicated~ to the likes of which you can't imagine! It's late Thursday~ gotta get up spankin-early for Canby, and I'd be happy to expound on the physics of *unsprung weight ratio* once I get home after Sunday. But suffice it to say that is soooo old-school~ I-beam, or (and this leaves a really BAD taste in my mouth) twin I-beam front suspension. I'll give you a quick example~ take your arm and raise it from your side up -n- down as quick as you can. Now, do the same motion with a 2-pound can of beans in your hand. Feel the difference? Now multiply that by 20-40 times (the weight of your car vs suspension).... I'm tired, and need some Z's~ but if you really need a more vivid picture painted I'll muster the energy first -o- next week... Scott Quote Link to comment
thisismatt Posted June 10, 2011 Report Share Posted June 10, 2011 Scott...you talk a lot without saying very much. Just sayin... Quote Link to comment
Z chopper Posted June 10, 2011 Report Share Posted June 10, 2011 well going I-beam axle up front is like going back to the boucing horse and buggy era. ofcourse if you build it as a gasser truck for drag racing why not. Quote Link to comment
Stoffregen Motorsports Posted June 13, 2011 Report Share Posted June 13, 2011 Well now that you've opened that door, why not weld in something like this. http://www.cachassisworks.com/c-75-g-machine-chevy-ii-components.aspx I'm still considering the 720 clip for my 320 though. Quote Link to comment
albyneau Posted June 13, 2011 Report Share Posted June 13, 2011 Scott...you talk a lot without saying very much. Just sayin... Yep, you're right~ and no offense taken. I figured that inquiring about suspension as he did, the concept of unsprung weight ratio had not been cast his way~ and was starting with the basics. I can get a bit wordy sometimes, but then all the students in a class~ or readers of a thread~ are not going to be at or learn at the same level. Now~ about the polar moment of inertia....:blink: :lol: Scott Quote Link to comment
68Datsun510 Posted June 14, 2011 Author Report Share Posted June 14, 2011 Oh i fully understand unsprung weight, its all a matter of inertia. I just didnt consider it. Matt, there was a 521 drag truck at Canby with a mustang II front suspension. It was AWESOME Quote Link to comment
