Datsun K-MAC adjustable camber & caster strut tops
Has anyone used these strut tops ? My car is a Datsun b310 4 door sunny square headlight The car had all stock running gear in the front until today I fitted new gas shocks inserts same length as stock, yellow low king springs, New maddat oversize sway bar and steering brace K-MAC adjustable strut tops and a strut top tower brace So car was stock Now has all this new stuff in the front Problem is the car sits 50mm higher with all the new stuff? Car has got no motor or gbox in it, when I stand in the Engine bay 120kg the car don't drop much. I think these k-mac tops are to blame or I haven't put Them in right, I basically just changed the old strut top with new Left all the other stuff on like the rubber shock cover protector Steel spring hat with the bearing and new k-mac top Anyone use k-mac tops?

Those are the wrong springs.

Might be worth getting weight in the front then having someone turn the steering wheel to the left and right just to get the suspension to settle back down. Hopefully it might drop a bit more for you.

As in the front springs are to stiff for the car dd?
Springs fit in cups nice and are all siting in the right spot Suppose to drop car 30mm to 35mm Got me thing now I think the camber top has added 20mm to the overall Length of the strut hence whey I'm high and maybe springs are to stiff as well

I have not setup those exact strut tops.
I have however built my own suspension set ups on many offroad vehicles. Agree with cadet1200, it will drop down with weight on the front and turning the steering from full lock to full lock a few times. You should also leave the lower control arm bolts loose. Until you get it to settle to ride height and then tighten them with full weight on the suspension. Allows it to flex and bushes are then NOT under stress when vehicle is at ride height. Hope that helps and it works out for you. We've all been in that moment, WTF??? "it's meant to fit" Followed by another WTF??

Not surprised as most cars of that era did not have Gas pressurised strut inserts, Seems everyone forgets that Gas pressure struts do act as very effective helper springs and that will be most of your problem.
Some are worse than others, I remember when one of my Works Stanza Rally struts lost gas pressure the front of the car on that side went down by about six inches as the gas pressure was so high in them. But I have seen Datsun 1600's fitted with the old Tokiko Gold inserts pop up a couple inches in ride height after they were fitted needing different springs just to bring them back to stock height and that was with the drivtrain in place. So in reality ddzongal is right on the money and the above explanation is why.

With my Sunny wagon, it also sits up at the front, using gas inserts. I think I've put Stanza stock springs in, which aren't compressing enough with the lighter engine. Plus the barstools are worn out after less than 12 months use. I'm going to replace the front end soon, so my solution for more negative camber is to use Stanza ball joints instead of Sunny. They have a greater offset outwards. I'll just have to lengthen the tie rods by screwing them out. I've used 200B steering arms in the past, with 180B outer tie rod ends to match the taper, but you need a spacer under the nut to get it to tighten properly. I've also got some shorter front springs that I'll fit, & another pair of strut inserts. I'm only using stock strut tops. I'm also going to have to find some heavier rate rear springs, as it goes into 'wormy dog' mod as soon as you put half a decent load in it. My old Sunny panel van with leaf springs was much better for carrying a load.
