Started on the left rear alignment last night. Thought I had it done but I was done by 10:30.  So I find the center of the frame 30" apart and mark them.  I have a magnetic laser pointer. Use a plumb to transfer the centers to the ground onto tape.   I stretch 2 tapes out, mimicking a 12' dia wheel.  A arm rearcends are more difficult to align them multi link.  1 full turn of the him is 1/4" change.

I need to check my alignment. Haven't since it was first done. Who knows if it has moved a bit. I think I'll just do that today while I wait for the fortin to get back.

Good idea.
I'm not trying to nail mine dead perfect because I know it will shift a tiny bit as it settles in. Hopefully not as much as my exh manifold  :m. I'm going to spin that heim back one half turn tonight and lock it down. Then onto the right side while the header wrap dries.

 I found the reason my car always tried to oversteer when turning left.  Car would like to spin 180 when sliding to a stop at times and would really like to oversteer at speed in turns. I had ,over the wheelbase,almost 3" toe out(one turn per inch)on the right side. Left was 1" out. I readjusted to 1" toe in each side and it should really help the handling on hardpack roads. I was going to set it to zero toe but thought ,why not see what a bit of toe in does. If I don't like it ,I know it only takes one turn to bring it to zero. I was very happy to see that the rear arms were still spot on square in the chassis. Hell,this went so well I think I'll check the front tomorrow seeing as how I have car centerline marked on the floor marked already.

I cut/pasted a couple things that explain it a bit better maybe.

Toe out on the rear will induce a slip angle on the tyre to increase rear end grip for acceleration. However, during cornering the toe out increases the tendency for the rear of the car to oversteer which is especially bad for rear wheel drive racing cars.

Toe in is a much more common setting on the rear of cars, especially on RWD platforms, as it reduces their tendency to oversteer and provides the car with high-speed stability making the car handle in a much more stable manner allowing the driver to push harder and faster.

Having toe in at the rear wheels will increase the high speed stability of the car round long fast corners and makes the car feel as though it has a longer wheel base.  :m :nw

Glad you found the source, sometimes those issues can hide and drive one crazy.

3" toe out is huge. If i read that correct you had 2" on one side alone . I can see what it did. The info you pasted is good info and i do understand the in is always best. Not just in the rear either.

Now in my case, I have a different scenero. My frame spring a bit the first time I cut the back off to covert out from the busa. It did again this time as well. Not as bad but some. I don't have the ability to pull it back square either.  So as of right now, the trans/suspension cradle is centered on the tube under the seat but its rocked. Not only did it spring torsionaly,  it went rt a tad. The back end doesn't track true with the front, off by 2". I can still align to the center of the rail, it will handle fine but I need to build a new chassis at some point.

Do you remember where you set the rear alignment  last on initial?  Would be interesting to know how much settling took place.

Got the alignment finished last night. Not shooting for perfect as I know it will settle and require another. So I am dead 0, we will see which way it goes.  Ready for axles and shocks. Go the tail pipe wrapped and painted last night as well.

   
The fact the motor hasn't been started in 3 years concerns me.

I do have a few concerns about my welds, load points being strong enough, motor hasn't started in 3 years, 2020 krx1000 coil overs on the rear, etc etc. Nothing I consider life threatening either.

Now I do have the coil rates/lengths and max preload , max psi , valving info and low speed comp adjustment knows 18 settings. No info to be found about on max depth on crossover ring.  Has 20" tall lower and a 9.5 tall upper, max preload of 2" ( 27.5" total spring height ). Crossover current setting is set .75" before upper coil binds. The 9.5 upper will compress to 4.5"....5" of stroke leaves 11" of shock and a 20" coil. Hopefully if its too weak I can drop the collar so I'm not bottoming out.  I bought new high psi caps with Schrader. Oem are rubber bulbs like filling a basketball, shit design and why they drop psi.  200 psi max, New cape are deep allowing for an extra 10 cc of oil too.

3" toe out is huge.That is 3" total at 110".  2" @ 110"on one side and 1" on the other. That is approx 1/2 degree on the one side and almost 1 degree on the other. Not as bad as it sounds. If i read that correct you had 2" on one side alone . I can see what it did. The info you pasted is good info and i do understand the in is always best. Not always best,depends on the use the vehicle is intended for. Not just in the rear either.

Now in my case, I have a different scenero. My frame spring a bit the first time I cut the back off to covert out from the busa. It did again this time as well. Not as bad but some. I don't have the ability to pull it back square either.  So as of right now, the trans/suspension cradle is centered on the tube under the seat but its rocked.

Do you remember where you set the rear alignment  last on initial?  Would be interesting to know how much settling took place. I THOUGHT I had set it to 1"@110" or just under 1/2 degree.That big ass tree I hooked probably had something to do with it . :m The 1/2 degree side did pretty well but the almost 1 degree side sucked.

Got the alignment finished last night. Not shooting for perfect as I know it will settle and require another. So I am dead 0, we will see which way it goes.  Ready for axles and shocks. Go the tail pipe wrapped and painted last night as well.

One full turn of a 3/4"heim is basically 1/2 degree on my car. Different a arm lengths will skew that.

Just got off the phone with McMullen. He said fortin made a bunch of parts for 45mm pinion support bearings that they don't even use now. Someone loaded wrong CAM info in machine.. Was supposed to be 50mm. He thinks they are correcting that with a new run and I might still get it done and shipped back by early next week. Fortin says the part is being run now. We will see. If it gets to where freight line will be too slow(about 10 days  beathorse.gif~c200) I may have to make an Arizona run to be back together in time for LS. beathorse.gif~c200 .

I hope it gets shipped to you in time with out a drive to AZ!

I was only measuring mine 6' in front of the rear axles.  The back end of my frame is twisted and crooked to the sum of 1.5*, twisted and prob 3* kicked over to the right. That part is mostly from being cut apart twice. Hitting the trees prob didn't have anything to do with it  :nw :m

I had to cut down 12 cv bolts last night. The cv flanges on the hv are as tight to the case as they could get. There's a warning in the info that came with it and its obvious. If your cv bolt sticks out past the cup 3/16" it will bottom out on the seal. I made sure I have .125" gap ..... one bt one last night. Double checked all jamb nuts and a arm bolts were tight. Should be ready for axles assy tonight.

I bought my trans cv bolts from Jimco Racing just before they sold out. Custom made just for Jimco by Reid ( https://reidproducts.com/?page=motorsports&nav=closed). Exact length overall,exact placing of threads and spline drive heads. I forget now but they were $$$$$.The owner of Jimco saw a post of mine on RaceDeezrt and offered them to me. I cringed at the $$$$$ but have not been disappointed with them.

Sounds like you are in good shape for LS. Nothing like last minute finishes.

I wouldn't have an issue buying expensive bolts compared to replacing output shaft seals. I ran then in out 3 times, each, and checked with a feeler gauge. Those little things eat up time and I'm still short, 1 or 2 threads of an already think flange imo. The threaded area doesn't appear to be quite 3/8" thick. The old flanges are not much thicker. Hoping to fire it off and start break in on the new trana sun. Possibly go for a ride.

Damn is right but not the word I used when I noticed it after welding it together  :m

Not only is it twisted helically,  the rear cradle is kicked rt so to speak. For a visual, when the layers are on the rotors, they left side lines up just inside the center of the front tire as seen in the pic above. The right side lines up on the front tires 2 " to maybe 3"  inside the center. I didn't measure as I will not fix it. I was able to square the wheels with frame and thats all I care about . The twist is in the frame and I noticed it when I was stubbing in the rear upper frame section the wing mounts too. Tried to split the difference and none of it will kill the steering offroad so all good.

Only thing you will possibly notice would be the tendancy for the rear to push to the side under acceleration and then the opposite side under braking. Might not notice at all in the sand.
