Y33 subframe bushing/collars

I figured id ask cause i havent really seen any dscussion on the topic. Is their anything available for this chassis? Input would really help cause I'm considering starting a little subframe project with a spare one I acquired.

What does it look like.

josh (brokey33) used s chassis subframe  bushings. i have a set of spl in stock if you're interested.

s chassis as stated slides right in.

just in case you didn't already know, collars/bushings/risers serve different functions.
 
collars - stiffen up the oem bushing
bushings - replace the oem bushing
risers (or bushings with adjustable spacers) - replace the oem bushing as well as raise the subframe for corrected geometry

Thanks for the input guys. Og thanks I know the differences just didnt wanna write a huge topic, thanks though homie 👍. Believe it or not my friends dad scraped the bare subframe for some $ for metal lol.
