Fully Independent Suspension Build

Man that is sick build you got going there. I love it.

Thanks Diesel. Appreciate it.

I’ve got the front suspension rebuilt enough for a static test. Work SO MUCH better.

Now I think my next issue to iron out is the rear shocks are too stiff with no adjustable damping or compression. I can’t tune them in because the spring rate is too high as well. I can’t get the needed preload on the shock to make it function the way I want it to without making the rear way too stiff. I Need to find some 16-18” shocks with rebound and dampening controls and a lighter spring rate.

I ended up canceling the order for the 12” wheels because I’m abandoning the Miata rotors for the time being. I want more tire sidewall than a 12” wheel 23” tire will give. I may end up going to a full set of TRX450R beadlock wheels and tires later and maybe some wider and adjustable front Arms. I think this will yield a better performance and more tunability.

Here she is tacked and mocked up for a stance and suspension cycling test.

More to come.

Here’s where I am with the front end. REMEMBER, this is NOT complete. I have a lot of bracing, welding and triangulation to do to make the front solid and stable. I just wanted to get enough done to check all the geometry and see if I finally figured out the dimensions correctly. Which I believe I did.

I scoured the internet and found enough pictures to do a 3D model of what I believed the angles and distances were on a 450 but with my narrowed sub-frame size as well. I think I hit it, if not I’m really close I think.

Working on steering.

Got her steering and rolling. Gotta take a pause on the project and clean out the shop. It’s getting where I can’t find anything and I need to work on my Caddy for a bit.

My Caddy. 1984 Coupe DeVille with only 12k original miles.

One last pic before the pause.

Pictures don’t do it justice. It looks so awesome in person.

One last last one. The steering angle looks good.

Marathon Matt · 12-08-2022, 05:03 PM

Dang that thing looks cool.

Little wash down.
