e90 subframe bushings dimensions

Does anyone have a dial caliper and a set of e90 front and rear subframe bushings? I'm thinking that if I have the dimensions of the bushings/inserts, I can DIY some urethane bushings for a lot cheaper than the $250-$300 it'd cost to get oem or proflex bushings.

Buy urethane rods. Saw into sections. Drill through the center axis of each with a drill press and slide a steel cylinder in. Chill it in a freezer. Machine it on a lathe to the proper dimensions...

What do y'all think? Did some searches and came up with nada. I may have to buy/return a set from my local dealership, but I really don't like doing that kinda thing (shopping one place just to buy from another).

Sounds like a lot of work man. How many hours would that take you to get all done?

1addicts found Prothane/ whiteline bushes to be similar & cheaper than powerflex

Performance seems to be the same. Look it up

umm they sell rods premade so machining time maybe an hour per set once you got things moving along? be kinda pricey if you had to pay a shop I guess... maybe not once you made a few dozen sets sets and sell them on ebay though...
