EP. 7 My BMW E30 Restoration - Rear Subframe - Restoration, Camber/Toe and Reinforcement

Hi and welcome to my channel,
In this video I will be restoring and reinforcing my rear subframe as the start to my rear assembly series.
This is a relatively quick process with not too many steps meaning it can be achieved easily.
If you have any questions please don't hesitate to ask!

Awesome video mate, just about to start underside reno on my mr2- gonna be using your vids to help with removing underseal and refurbing subframe

[@BadE30]

Cool man! Good luck with it all.

[@xelad6159]

Really nice work, can't believe how rotten the subframe was

[@BadE30]

Won’t even be worth scrapping it! Nothing left..

[@LearnToRace]

Gotta love POR15 used it on my classic mini

[@BadE30]

always my go to for anything like this!

[@LearnToRace]

@@BadE30 yeah I've got plenty for future jobs, I painted a peice of paper with it to test how tough it was, you should try it, the results are good

[@BadE30]

I have done similar by leaving it in a tub, super durable!

[@tiitsaul9036]

Good work. If you’re planning to lower the suspension at all, you’d benefit from switching subframe bushings the other way around. You’d want to move subframe as high as possible.

[@BadE30]

Thanks, I didn’t know that but it makes sense! Will have a look at that

[@crap_car]

Nice work. I used POR15 on the E36 I'm restoring. Tonight we are removing the rear subframe off the Rover Metro we are doing. We are most likely going to get that powder coated. I just need to hunt around to see if I can get any poly bushes for it.

[@BadE30]

Nice one! Powdercoating is definitely the easy way around it. I just like to do things myself when i have the time, not always possible

[@jameshay469]

Shame about that original subframe. Great job on the replacement though, always impressed!

[@BadE30]

Some things are best to be scrapped! Happy with how it all came out

[@MstreetDriver]

are you happy with this style of adjusters or would you go for eccentric ones after trying these?

[@BadE30]

Unfortunately not got to the stage of driving the car and testing them out. However I went with the serrated versions due to recommendations, the eccentric type are know to slip, this is due to the flex in the bracket causing them to come loose

[@mcjjordan]

Do you think adding the edges makes much difference?

[@BadE30]

this makes it easier to adjust as it stops the plates from rotating away from the serrations

[@becomematrix]

What kind of welder do you use?

[@BadE30]

R-Tech 180 MIG, works perfectly for what I need!

[@selespeed3]

you must not use PU bushes. too hard on a aeak car body. you will destroy the car body. use original pliant ones. softer to preserve the car body. that is why BMW engineers decided to use softer rubber bushes in order to protect the body frame. if the car is what you wanted to protect over long term, don't use PU hard bushes. hard doesnt mean good.

[@BadE30]

I understand where you are coming from, however I am going for a different setup compared to when it was produced, the car will be a fast road setup. I am keeping OEM bushes for the complete drivetrain. I have added a lot of strength with reinforcements in areas known to have issues

[@selespeed3]

​@@BadE30 you re-enforced car body? this is the weak part and hardest to repair/replace. that subframe rear axle frame is easy fix. dont crack the old car body. metals fatigue over time. afterall, this is a 30 year old car made from era of low tech.
