cleaning up the IRS and diff on my TII...bare in mind this is will be a street car basically maybe the odd autocross, so closer to stock NVH(noise,vibration,harshness) is what I'm after ... just replacing with stock rubber bushings,basically the front rear trailing arms ones and DTSS eliminators... the two other ones are fine unless I use the whiteline camber bushing...have a couple of questions.

1.Mazda comp rear diff bushings and pineapple mounts...are they noticeably stiffer and increase NVH over the stock bushings? (real world answers from people running them would be most helpful )


2.whitelime rear upper control arm camber bushings...opinions on these.. heard they need to be modified to fit the trailing hub arm as the bushing and alum. offset dowel are too wide for the trailing arm hub? how much of a pain are these to make fit?


cheers

1. I didn't notice any real difference in NVH with mazdaspeed diff mounts.

2. I wouldn't bother with the whiteline mounts. you won't be able to adjust camber there with the DTSS eliminators in anyway. if you really want to replace that bushing use either a PBM bushing or supernow:

thanks ...appreciate response...did you notice any improvement in those mazda comp dif bushings? this is really just going to be a street car so wondering if it's worth the effort/expense to replace the rear diff casing bushings.
I'll probably leave those rear upper bushings in place since the suspension is oem rubber..

i actually like the comp diff mounts more, no increase in NVH, big decrease in drivetrain slop.
