EP. 11 My BMW E30 Restoration - Rear Trailing Arms - Complete Restoration & Reinforcements

Hi and welcome to my channel.
In this video I will be showing you every step of my rear trailing arm restoration.
I chose to add the reinforcement kit due to the incresed power of my engine swap and increased rigidity of my suspension components.

Awesome job dude, glad you modded the rear arm mod now, rather than finding out the hard way later. 😅 Looks like it should fit just fine the way you've done it, similar to what I ended up with. 👍

[@BadE30]

Thanks man! It is a shame this issue was not stated when purchasing, but I was lucky to find out before it was all ready to go!

[@RestorationApprentice]

Great work, as always!

[@BadE30]

Thanks my man!

This is awesome!

Thanks😎

Lovely old job mate, reminds me of spannerrash’s resto! Top job

[@BadE30]

He’s a great guy! Cool to see others also keeping e30’s going

[@kieranpaulson8691]

Your explanation and general knowledge is awesome , you’ve become so what of a hero of mine …. I pray to meet you one day ❤

You know what they say, never meet your heros💔 but please keep watching my videos as I want the ad revenue

Great work bro👌🏼, I’m gonna do this soon

[@BadE30]

Go for it!

Nice job again, would recommend using compressed air after welding to help distortion, 😎👍🏻

[@BadE30]

I have always been told to be wary of speeding up the cooling process when welding, it can develop martensite but you are potentially cooling fast enough to de-temper the steel and cause porosity or cracks. Luckily these were just small welds so no extreme distortion took place!

You love that Por 15 😂! Great resto man! Keep em coming

[@BadE30]

I’m running out of parts to use it on! Haha. Thanks 😎

[@dhilankerai3585]

@@BadE30 what are your plans for the e30, OEM+? Surprised you didn’t go for a 5 lug conversion and a BBK

[@BadE30]

OEM+ yeh, I want 15” wheels with big tyres, and 5 lug wheels are not as popular in the smaller sizes! Also got the big brake kit on the front, just kept the same at the rear as my goal isn’t tracking it etc

Have you had any issues with bushings squeaking?

[@yuvalmelamed5185]

Did you make the reinforcement kit yourself or did you buy it ready from a supplier?

[@e30_318is_project]

Niceee!

[@BadE30]

Thanks!

[@Kris-82]

Can you link the sleeve kit for bushing removal?

Super clean please do mine for me😢

Wish I had time for others! Maybe in the future 🤔

[@freakboy9189]

Quick question, after sandblasting, the metal prep stage that you use, is that enough to allow the POR to adhere to the metal? I've been all over the internet and I can't seem to get a solid answer.

[@BadE30]

Hi. I have had a lot of experience with the paint and doing what exactly that, i have an no issues. In fact I have found it to be very versatile, the sandblasting creates a well etched surface, and the metal prep helps this as well!

[@richardknowles1548]

Did you wash it after etch or straight to paint?

[@BadE30]

@@richardknowles1548 I washed it off, that’s why you can see a bit of flash rusting. I would recommend drying it as fast as possible once washed, either using a heat gun or compressed air

[@Dildology]

How many coats of por 15 did you apply?

[@BadE30]

One coat is sufficient for the smooth surfaces. But on the cast surfaces, it usually takes two as the first coat sits into the shallow parts of the cast revealing the peaks

[@OldspoolMatt]

link for the press kit? @Bade30

[@coltuppal]

very poor design of the strengthening kit by born to drift. you should not have to modify it especially as the modification you.ve done is going to weaken the strengthening. i found out the hard way when i put it all back together and it started to rub the fuel pipe

[@BadE30]

It should for sure state this issue, I presume it is for e30's with a modified fuel tank. Shame it wasn't mentioned to me until I purchased the kit, I am happy the structural integrity of the modified side is adequate, still a pain!
