I have mostly finished the rear end of my car. Just to remind everybody that I'm using the NC MX-5 rear end w/crossmember. Using everything from the NC rear end.
This was easy to setup, since only the height I had to figure out, but the front is a whole new animal.
Specially that I don't know anything about suspensions.
I really need your help here, with pretty much everything.
I'm reading, watching Youtube videos and I'm still not clear on where to start.
I know, that the LCA has to be parallel to the ground, and "V"(A arm) parallel to the car's centerline.
I'm using the NC front knuckles, that are a bit weird, in a way that the lower ball joints are installed from the top down.
I'm not sure what should I use, for the chassis side, I would prefer adjustable bushings, since it will be a street car, but if you can convince me that the Heim joints are much better, I may go that route. Also I need help with thread size and hole size. I'm thinking about using 5/8-18 thread and 5/8" hole, or 1/2" is enough?
Tube would be 1" and .083" wall thickness, that sounds about right? Low carbon steel 1020 DOM is OK?
Kinetic(Jack) sells those lower control arms, but I personally I don't like how they look, specially that rectangular tube. Sorry Jack about that.
Most likely I will use his upper control arms, I like that design and how they look.
I'm thinking about using a piece of square tubing, as a bracket to the chassis side. Maybe something even thicker, than 1/16th wall thickness.
Another "issue" is that, I have purchased some earlier Miata ball joints, since the NC comes only with aluminum control arms with integrated ball joints. These(bottom ones) are angled downwards, which creates a bit of a challenge, on how to join it with the rest of the control arm.
Most likely, I will have to use the 2.5"x1" tube, but that tube is pointed downwards at an angle. Now that tube, at that angle has to be joining with the two round 1" tubes.
The upper ones are the recommended ES2407R ones. Another issues has arises with these(all 4), that I have already took care. The taper angles, and diameters don't match with each other. Knuckle holes are bigger and deeper, than the taper diameter and length of the ball joints.
I have machined taper sleeves as adapters. I have also machined a bit off from the top ball joint mount bottom part, where the nut goes.
I will be using weld in bungs in the tubes. Material for these matters? Can be mild steel/low carbon steel, or has to be 4130?
I have measured the knuckle and inserted in vsusp and I came up with this specs. First time I'm doing something like this.
As you can see, I need a lot of help. It would be much appreciated, any help or pointers that you guys can offer.
