ok i know the subject has been gone over alot and asked alot, i have searched and it really hasnt help to much. so i have a few questions, i know you can put the 280zx hubs,spindels and struts on a 510 front end but what has to be modified to do so? i read in here of people cutting them and shortening them. i just need to know what all needs to be done to get them to fit a 510.


thanks

Unbolt complete front strut/hub/brakes from 280zx, bolt into datsun 510, AFAIK. All mounts/bolts are same pattern. Use ZX brake lines?

Shortening struts is for going maor lowar.

I like the new classifieds better.

The 280zx spring is too big for the 510. spring, perch, and top hat must be removed and replaced with a 510 perch, spring, top hat OR adjustable coilovers. I say go with the coilovers. You don't HAVE to shorten the struts, they are a little shorter than stock 510 struts already. use stock or zx brake lines, and I highly suggest new master cyl. from a 280z if you are keeping stock rear brakes or a 280 zx master if your doing rear discs too.

So the ZX strut bolts the same to the steering arm?

...seems to me we are being held hostage by these candy-ass pussy, limp wrist, hanky twisting, girly-man, cry when Forrest Gump's mom died, crystal gazing, Om chanting, sandal wearing, whiny voiced, oh I broke a nail, fucks.

Lower mounting points are the same 280zx / 510. the struts don't bolt to the steering arm at all, the lower ball joint that the strut mounts to is attached to the steering. the whole strut turns when the car steers.

When I did it, I reversed mine(L to R, R to L). Otherwise the caliper has clearance issues. They bolt right in, but as was mentioned, the springs are too large. You have to either go with coilovers or weld the 510 spring perch onto the ZX strut.

I recently did this. You can switch the struts like Micro is saying. It will make it easier to change pads in the future, but its not impossible.

I did mine the uber cheap way, and without a welder.

Here is the 510 strut, you need the lower spring perch off of it (try looking thing).

You also need to remove the lower spring perch from the ZX struts. I then used my grinder to make it smooth.

To hold up the 510 spring perch on the ZX strut, I am using these "collars", 2 inch ID.
Posted Image

Use the 510 top suspension parts. You can trim the ZX top plate to fit in the 510, I hear this gives a little more drop.

I did not switch my struts, and therefore calipers. I also used my stock 510 brake lines. Once I got into it, everything was straight forward.

Why are coilovers the best way? You already have the 510 springs and perch right there. Collars are only $25 x2, coilovers are over $200 set???

Or do you mean best for lowering?

My Friend Vince installed ZX struts in his 510 with the ZX springs and perches. He had to trim the inside of the strut tower at the bottom to make clearance for the wider springs. He also trimmed the ZX top hat to reduce the diameter so it could fit in the 510 strut tower. He cut one coil from the springs and the ride height was nice. The car felt good with the ZX springs on it.

I have coilovers on my ZX struts and I did the no weld method with the shaft collars.

If you can use the larger diameter zx springs there is little room for camber adjustment inside the strut tower. A narrower spring is better. As for adjustable coil overs they are great for racing or if constantly changing tire or spring sizes or rates but otherwise you are spending a lot of money on something you adjust once and forget about.

While the spring is off your strut you might consider replacing the factory strut hydraulic fluid with something 'thicker'. The fluid in my Maxima struts was thin (probably 5W) as water and I replaced with 20W motorcycle fork oil. The thicker oil much inproved the damping action. Fork oil comes in a variety of viscosities for tuning bike suspension performance. I trimmed my 710 springs and fit them on Maxima struts that were an inch and a half shorter and replaced the oil. My calculations show a spring rate of about 150 (up from stock 110) when shortened. Love them.

I fully agree. I was only letting people know that it has been done and works well. As to camber, you can use adj. control arms if you need to.

I only did the coilovers cause I got them cheap ($100 for the set on fleabay) My other 510 has stock 510 struts that have been cut down and the lower spring perch is adjustable with a shaft collar.

How are the LCAs adjustable? My camber plate is hard over and I don't think it's right yet.

He did not say to adjust the LCA. He said use adjustable LCA's.

Good! Hate to think is missed adjusting it.

Hmmm I have a second set of LCAs....maybe skip the Heim joint and weld something up.

Adjusting the strut outward would also throw the tension rod out too wouldn't it??
