Some update photos from tonight...

Got one upper rear arm pretty much finished:



Here are the 90% finished rear uprights:


I was playing around with the frontend tonight and found out that Porsche 914 tie rod ends fit perfectly in a 240sx knuckle end.. might be able to use this to my advantage when buying parts, since I have to get a Porsche 911 turbo rack ball joint & tie rod end kit for the steering rack.


The frontend is going to need some serious widening...


Detail of the welds on the upper mount of the rear upright:


Measuring for a swaged steel tube for my toe adjustment. Looks like a 9"x 5/8" threaded tube will work well.


The backend is starting to look more like a car:


Detail of the suspension geometry. Looks like camber gain is acceptable throughout the travel too. right at around ~0.5-0.6 degree per inch of travel. The arms look like they will provide more than adequate adjustment as well. I was able to go from positive to negative camber just with the upper heim joint being adjusted.

Holy beautiful welds Batman!!!

How will the rear brakes attach?

I'll cut another bracket out that will weld to the side of the upright to hold the caliper. Thats one of the last things I'll do.

That's kind of what I figured. You need to have everything in place, including the hose before you can determine the final placement, I suppose.
I'm learning a lot watching this build. Thanks for sharing!

Here is how I'm doing the rear suspension coilovers:



Another setup done the same way:

yah i figured that out after a little bit of wondering why the hell it wasnt welding very hot when cranked up. fixed the poles and oh yah it was ON! i have been too busy to play with the welder and speed up the wire. i'm about out of gas anyways.

Soooo.. I'm in the planning stages for the front suspension and steering now...

I measured out the rear trackwidth based off the WMS and mocked up the frontend with the same measurements. Here you can see the knuckle sitting about where it will with the finished suspension:


Front view of the same..


Worked on dismantling the steering rack to see how it goes together, and came up with a great idea on how to put the steering together without a lot of expensive parts...


Found that the end of the rack sports an M14x1.5" threaded hole. This will allow me to secure a clevis to mount a high misalignment heim joint on the end of the rack:


This heim joint will then allow use of a swaged chromoly steel tie rod adjuster for a standard sprint car application. At the knuckle, I'll drill out the tapered tie rod end hole to accept a 1/2" or 5/8" bolt on which another high misalignment (left hand threaded) heim will be mounted. This will really simplify things and I wont have to bother with making a custom tie rod nor will I have to purchase the Porsche 930 turbo tie rod kit for the 914 rack.

Here are the ends of the stock Porsche 914 tie rod ends:


Here are the Nissan 240sx control arm ends. I hacked these off to start making the lower A arms for the frontend:


And heres a shot of the backend with all the A arms in place:

Here is how the front suspension will be done:

You ARE the Man!!!!! You Win!!!! AND Niiice! Later...

that thing will be wicked. You've got me thinking....along some different lines, though. Anybody that hears of a wrecked 86.5-95 nissan pickup/pathfinder somewhere near kansas, let me know.

Wow...long arms on the front! you could build in some huge travel there!

I have 3 zx7r shocks coming in the mail now...

I've also got 2 of these that I'll be getting int he next few days:



These are off of a 2000-2003 Yamaha r6 motorcycle. The reservoirs are located differently, so that might help with fitment issues. Also, the r6 shocks are nice in that they have heim joints on both ends, rather than a clevis and a heim like the zx7r shocks. The r6 shocks also have fully adjustable bump stop and dampener rate.

Remote coilovers--that's darn close to F1 type pushrod actuated suspension--outstanding!
