[Clawhammer]

[USsil80]

what is the point of doing this.. y is it better than just the stock one ont he 240???

It makes your car about 16lbs. lighter.

[nismofly]

and thats unsprung weight, so it has a lot bigger of an effect than the number implies

How noticeable is the effect? Elaborate please.

W did the same thing except we used the stock shocks. I took a cut off wheel and cut off the bottom of the round end of the shock, but left enough about the size of a quarter. Then I cut some stock from a piece of rectangle stock, drilled a hole for the shock bolt and welded it on to the remaining steel. I wrapped the shock in a wet towel to keep it cool and took my time welding it so it wouldn't over heat

wow 16lbs lighter? I can take off 16 lbs by just taking a fat dump haha!!

[Clawhammer]

lol that's quite a dump. I find it to be aesthetically superior to gutting the inside or your car, especially if it's a daily driver. And depending on how crazy you go pulling stuff out, it's likely nominally supierior as well. And if you're really crazy you'll just do both!

What about the importance of the washer pictured below? Isn't it needed since the z32 upright is aluminium?



According to this guy...

The S chassis does not have washers behind the studs, Z32 does.becuase the knuckle is alum, the bolt head needs a washer, otherwise it would gall

Is this some type of special washer, or would any washer do?

My uprights had the 5 lug hubs attached to them, which I used, so I had those washers even when I used the uprights with 4 lug and then eventually swapped to 5 lug. I always used said washers. They do not appear to be special, just a washer. Hope that helps.

Umm, that's weird. I put a link to Fresh Alloy, but it changes as soon as I post. Nico is hating? Anyways here is the link if interested, your just going to have to copy and paste.

Wow. I guess i can't advertise other forums on NICO!

It's 8lbs per corner. 16 lbs of unspring weight is huge. it's worth every bit of hassle to run z32 uprights.

not only do you drop big weights near the corners, you make it easier for the suspension to do it's job.

everyone serious about tracking their car should be doing this.

i've been wanting to do this eventually when i get coils, but my friend just got the uprights from a junk yard for $60

[killernoodle]

There is no sense doing this unless you just do a q45 rear swap IMO.

With the q45 you get bullet proof axles, aluminum uprights, and a VLSD. (you need to get a 300zx turbo axle though for the other side)
