Rear End Noise: recently installed parts - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I bought KW V3's which I installed with stock tophats, since they dont come with any; Im planning on getting some adjustable ones in the near future.

Then I got SPL RUCA which i installed before i got an alignment.

Then i got some wheels 18x9 +22 and 18x10 +22? with 235/40 and 265/35 in the rear.

After installing that little by little over a 3 month span, I noticed many different sounds coming from the rearend.

I think that my rucas are not sitting level which makes a cluck when i go from a complete stop then accelerate. I think its hits against the cone space which causes that noise.

Is there any way to get that center not tilted to the edge.

Any help is appreciated

Sure it's not subframe bushings?

Or other failed bushings?

Im planning the rest of the adjustable arms to replace some of the bushings

Im dont really want to drop the subframe to install solids ones.

Subframes with worn out bushing will click for sure... You can always go polyurethane from Energy to replace... There was one other company that makes replacements too, but sorry I couldn't find it.

did you put the little gasket ontop of the top hat? cause usually that makes funky noises sometimes

It has nothing to do with your subframe bushing's or your RUCA's. Your coilovers are bouncing up and down in the middle of the tophat and its making noise I can't figure out how to fix it either. watch the whole on the strut tower and bounce your car up and down and see what im talking about. im gonna try and put the factory rubber bushing between the tophat and the coilover itself and see if that solves the problem but i dont see how it would.
