sub-frame collars

[captainluigi]

anyone no of collars of material other than aluminum? poly? hard rubber? i'm just thinking i will not like the noise increase.

[NOR*CAL 916]

polyurethane bushings i dont know if they make them for the Q45 but thats your best bet for aftermarket.

The increase in noise is NEGLIGABLE at best. maybe 5% increase at worst.

Youll like em, trust me. its a 1 hour install for the subframe collars vs 5-8 hours for bushing install.

Trust me, I am ultra sensitive about noise and vibration increases and you wont be disappointed.

Look at it this way. you still have a rubber bushing in place, so going top to bottom you have collar-rubber bushing-collar, so you still dont have any noise transferred.

o.k. then. i'll order today. the ones for a 300z are the correct ap?

[elwesso]

yeah 300zx and 240sx are both the same.

Do you have any instructions on how to install these?

[elwesso]

Yeah..

1. Jack rear of car up2. Place jack under subframe (2 jacks may make it easier)3. Unbolt 4 nuts holding subframe to chassis.4. Lower just enough to place the top collar on (sliding it on). 5. prior to installing bottom nut, place lower collar on.

Hardest part about this job is fighting the bolts and nuts off if you dont have air tools. if you have air tools it will be cake.

Great!Tks.

once these are installed, does the car sit slightly higher? Any good sources for these?

[elwesso]

no it doesnt change the ride height of the car. Thats because the spacers take up SLOP that is there. Basically theres a gap between the top of the bushing and the frame of the car, and the spacers just sit inside that gap.
