Why the rebuild on the busa?

Well, I heard the rail run before buying the engine.  It was a little hard to start but seemed to run fine.  When I got it home I found it had sucked on a lot of sand.  Figured it is easier to do it now while the engine was out.

The red lines on the drawing are supposed to represent the shocks.  I keep going back forth on 6 link or arm rear end but right now I am leaning towards 6 link.

nice work.What's the reasoning for the 6 link?

Seems easier to build and once it is done it can be adjusted in the field if needed.  It also seems like if one was to bend some thing, not that I would do that but on somebody else car, one could use one or two links from the other side to get back the trailer.

Why not just do a 5 link? Simpler yet. Not trying to be a pain ,just asking .

No great reason other than having some built in redundancy in the suspension.

DS is in his ear?  LMAO
Frame is looking good, the time spent collecting $$$$ parts before you start really speeds up the build.  Cant believe you didn't like the skewer nose.  ;D

didn't want to go with the point huh! lol
well it looks like a pretty close copy but I can see a few diff's you have changed aside from the nose. looks good and don't forget to add the bracing to the lower frame section from rear to front. I see the 2 tubes under the seat to the nose and that is good although it might make pedal placement a little more tricky.  so how wide is the inside elbow to elbow?

Thanks, ya I couldn't leave the design alone I had to change some stuff but I have kept true to the general lines of your car.  It has 60" elbow to elbow.  I wish I would have made it a little taller.

The brakes are going to be reverse hanging and I will add a tube across the floor to brace your foot on.  Learned that from the RZR's.

The rear will be the 1100 paddles and the front will be the largest tire I can get to fit on a 4" rim.  The street tires I got are the $25 tires from the used place.  Figured the are good enough to play around on and decide what to get later.  They are 30" tall.

Thanks again,

30" is a good starting point.

why i asked..........if you go with a 7.60 5 rib or cutting tire on the front it should measure 28" tall depending on manufacturer. if you run 28 or 30" in the rear then you will have a balance issue. when i say balance i mean equal ground clearence front to back. now you really prob want the front to sit 2" higher than the rear w/o passengers. the tube you have welded across the lower frame behind the seats that you rear susp and engine cradle will weld to might need to be changed. i put a 35* bend on the ends of this tube to drop it 3" down. the reason for this is where the lower a-arm mounts to the front susp cradle is at the bottom and the spindle stub is located at the bottom of the spindle upright so the center is low. even if you could mount your rear links or lower a-arm in the rear at the same point , your wheel bearing or hub center will prob wind up centered on the carrier, so you already have lost ground clearence compared to front. now my bet is that loss with a 30" tire will amount to prob 2" to 4" ( depending on angle of rear cradle) and depending on where you mount your jeffco you might not be able to mount the lower rod/a-arm tabs as low as the front cradle so another 1" to 2" ground clearence loss too. this is why i drop that tube down the 3" and then brace it to the frame accordingly. and i do mean brace it!  not saying you need to change it but you might want to consider it now rather than later, i know you were baseing your build off pic but you can't see all in a pic.the fram looks good from the pics but the front cradle looks real nice btw  ;D

I think the rear center bracing is more needed w/a-arms than link style.  The forces are just placed at diff spots on frame.  I know on my A-arm I had some serious frame flex problems first time out at dunes.  DS did a great job supervising me while I welded tubes at dunes.  Then I added more tubes when I returned home to carry the forces thru the bottom of the chassis. 

PS. by supervising I mean he sat in a chair w/cold beer and watched.  rofl ;D rofl
