So, I've got a project s12 hatch for $500, and I'm looking to set it up to handle nice. I've figured out how to make s13/s14 parts fit from info on zilvia and club-s12, but I suppose I'll have to ask you guys if I actually want it to turn. Right now I'm only dealing with front suspension, later I'll tackle the rear.
First, some of the s12 specific info I've gathered:
I'm trying to get the car to slide and I'm going to lower it, but I'd like to keep correct geometry and good setup in mind, while putting sturdier parts on it that will be safe to drift on with the extra power of a CA18DET swap in this aging chassis.
Now, the questions:
I'd like to replace the balljoint with a spherical so I can get roll center adjustment. I know I've seen links to spherical bearing cups on here before, but I can't find them again, and I've searched speedway motors and they don't seem to sell them either. Could anyone provide me a link to either 1.5" bearing cups or 1.5625" cups (preferred, so I can run a high-misalignment bearing).
Is there anywhere I can buy the clevis / u-bracket things as seen in the "DIY traction/tension rods parts group buy", but with normal standard threads and they don't have to be as sturdy. The stock swaybar end-links are a pin type, so I need a pair of those to bolt onto the LCA and swaybar to be able to mount rod ends for links to replace the aging stock ones.
How is the narrower track width going to affect my geometry, are there any obvious concerns? I guess since the LCA's are closer to the center of the car, the roll center height will change faster with ride height, I'm not sure if that's good or bad though.
As more questions/problems arise, I'll ask them here instead of making a bunch of stupid threads
First, some of the s12 specific info I've gathered:
- The s12 is very similar in front suspension design to the s13, but the frame rails are closer together by maybe 1-2" to shorten the track width, and as far as I know the crossmember is narrowed in a similar manner. If I need to start determining roll centers, I have an s14 crossmember to compare to to figure out exactly how much it's been narrowed.
- The inner pivot on the LCA is the same as the s13, I can attach any s12, s13, or s14 control arm, and the s12 control arm can use the same bushings as the s13
- The balljoint bore is the same as the s13 and s14, so I can swap to s13 or s14 balljoints to fit s14 knuckles.
- The steering rack is normal nissan thread, so I can use s13/s14/z32/z33/etc inner tie rods.
- The 3-bolt circle for the tophats is the same as the s13/s14, so I can use camber plates / tophats from the s13/14.
- The car has already been converted to fit s14 tension rods and brackets. I think the brackets may be further from the control arm than stock, because stock s14 tension rods pull the control arms forward and give a fair amount of caster. Perhaps the LCA mounting point on the subframe is moved toward the rear of the car to shorten the wheelbase.
