Anyone making a solid (aluminum) suspension bushing set?

I am lookin for some also,,,,mainly for the front-upper-A Arm bushing that are drilled off-center so that I can get more camber without using after market adjustable camber A Arms...like the SPL ones I have on my car today.

Why: NASA charges 4 points for replacing these A arms and that put me up a class : from TTC to TTB...sux

So anyways, I may try to have some custom built just for that purpose,,,I know that some of the SCCA T2 guys run them,,,and I believe they had to make than.

I'm testing a set of offset Hydlar front upper control arm bushings on my car right now. One more track event, then I'll pull them out and inspect them.

I would love some delrin bushings for all the lower shock strut mounts and the front lower control arms. My buddy has yet to get his lathe going. I would buy urethane but no one makes them.

I just want the bushings our metal mounts are strong enough.
The price of nismo bushings is $35 a piece for the front control arms someone can't do some delrin ones for cheaper or the same? While I am at it how bout a trans mount insert out of urethane and rear diff mount inserts. The product developement for parts such as these is way behind...imo
I know spl has aluminum parts available, but I am not that hardcore.

I made them for myself and one other member on this site. If I'm happy with the testing I might makes a few sets and sell them.

None of them will be possible with delrin or alum, only the upper a arms. Lay on the ground, have someone move the wheel lock to lock and watch, the bushing are made to deflect in multiple direction, and thats without the suspension moving up and down.

Yup. Most of the bushings in the front and rear on the 350Z are multi-axis articulating. That's normal for a multi-link suspension design with anti-dive built in. You go with hard durometer rubber or monoballs.

Delrin bushings are great. They have a built in lubricant and I used them for years with my old GT car. Of course you have to cut them yourself. Any large plastics supplier will have them.

Good Question, I believe this needs clarification with NASA:

From the NASA TT rules book
"Metallic replacement suspension bushings (Heim joints/spherical joints) +3 (except for pillow ball camber plate joints, sway bar end links already assessed points in 6) above, and upper control arm spindle/knuckle joints already assessed points in 7) above)"

But this section is clear on the A-Arm replacement(and maybe a bit unfair to the Z)

"Replace or modify control arms (other than plates, shims, slots, or eccentric bolts/bushings
for simple camber/caster adjustment only)(may have upper arm spherical/metallic joint(s) for
the connection to the spindle/knuckle) +4"

But there appears to be "grey area" that a competitor can use to his or her benefit!
