why solid bush rear subframe???
I followed your suspension conversion very closely and it was your experiences that drove me to do the same for my 993TT. It completely transformed the car from a wallowing cruiser to a tight sports car. I'm amazed at how little noise/harshness is added to the car with the fully solid suspension!
Best modification for this car; hands down!
if so I did all RS rear arms w/ ERP solid non tilt subframe mounts and Tarrett rear toe links
In front I used Elephant Racing sport rubber A-arm bushes, I would have used the Elephant bushes in back too but also wanted all new ball joints. The RSR's experienced ball joint failure regularly back in the day.
here is the rear parts list

I'm replacing all the rear arms, very likely going with RS A arms and KT arms, as Bill noted in many other posts these haver stiffer bushings. Doing also OEM camber arm + Tarret rear toe link arm.
I did notice the price difference of say the Tarrett solids vs Elephant racing rubber is only ~ $50. Assuming might as well just go solids if I proceed.

How much labor is involved in the changing subframe mounts? Keep in mind I'll be doing the the rear arms as noted above.
As Overboost mentioned one of the challenges is simply removing the existing bushings. +1 on the air chisel!
btw, I ended up going with the Elephant Racing Sport Hardness bushings (equivalent to RS). I heard the solids can lead to a dramatic increase in NVH, as well longevity not as good too.

Happy new year! Thanks for your time, in advance!
