Jeeze, I agree. If I had the funds I'd do the same with my 335. Also agree about the awesome videos!

As far as you went with this I would have probably sprayed the front and rear subframe powder coated or ceramic. 🤔 still looks crazy lit! Nice job!

[@MillerrMedia]

N54 Lord I had that exact thought..

[@josephrosenbauer6591]

MillerrMedia unfortunately we did this entire job front and rear in a single weekend, so we really didn’t have time to send it out to be coated but your right, it would have been ideal.

[@jake_spence]

Agreed! Like Joseph said, we were in a time crunch. I will still try to mask everything off and prep/paint the rear subframe at some point.

Joseph Rosenbauer I do get that but being the car is going to be down for the winter why not wait till you guys had the time to paint everything while it’s apart, more efficient then doing it twice🤷🏻‍♀️ just my two cents👌

[@chadparries5628]

Incredible video. Probably my favorite of all of them. So informative and that parts list with links is pure gold. Although after clicking on most of the links, the cost to do all that plus time and tools is no joke. Very similar to the cost of converting to single turbo. BUT boy oh boy are you going to be able to put that power to the ground now. Really excited to see this car back at the drag strip. The install seemed to be top notch, really enjoyed watching your friend work. Jealous of all the wheel/tire choices at your disposal now!

[@jake_spence]

Thanks Chad! It's definitely similar to the undertaking of a proper single turbo install. I think the car definitely needed all of this for the way I've been using it. I'm glad you're still following along, even if I'm not posting on the forums as much.

[@micraw714]

Nice I bet you're loving that diff! I installed the same one about a month ago. I kind of regret going with shorter gears on mine but I'm pretty used to it now and it does ok with the stock twins. Totally transforms the car!

[@jake_spence]

I am loving it! Sucks that I haven't really been able to drive it because of the snow. But I'm itching to get it out again this spring. I enjoyed the stock ratio because I do 1/2 mile 170mph+. But shorter gears would be good for shorter tracks.

[@micraw714]

@@jake_spence heck yeah I bet you're itching to get out and drive it! It totally eliminated that little pause/spin when boost kicks in for me and corner exit speed increased a lot too. I can imagine that in conjunction with solid bushings, holy cow!

[@myboybill01]

Fantastic effort. I'm blown away by how much work that was to swap all of that out. Makes me wonder if my 2008 335xi will need any of those parts. I just got into autocross and drag racing last summer and will be hitting it up again this year. Man I love my car. It's such an improvement from the 3 Ford Taurus' I used to own.. Just put in a Spec single-mass lightweight flywheel and clutch last month. Next is the intake, intercooler, and spark plugs.

Also, I have the bilstein b14 coilovers and they’ve been great so far. With them raised all the way up it lowered my 335is about an inch but if I put them lower it will rub so I kept them all the way up. They feel stiffer than stock yet smoother at the same time.

Good to know! Bilstein has been a great name in this platform for a while. I'll consider them when I continue my search.

[@jake_spence]

I'm glad you found it helpful! It's been great so far. There isn't much additional NVH, honestly. There is a slight diff whine with the poly bushings, but my car is gutted and with full interior I don't think you'd hear much. No additional vibration.

Since the car is not stock anymore and you don't care about intrinsic value, you can do what you want. I don't think it will be pleasant on the street but should do well on the track hopefully.

[@jake_spence]

Yeah, this car is meant for the track at this point. I will say it's not that bad on the street, but it's far from comfortable at this point with no interior and race seats.

[@fw1421]

You need to use rust converter on the rusty suspension parts and paint them to protect them from future corrosion. Bare metal will corrode quickly without protection.

[@jake_spence]

True, I will be doing this in the next couple of months.

[@dr4109]

Great build! I wish BMW did a LSD from the factory.

[@BimmerM5e39]

Saw it all, damn it was long but I finally saw everything involved in great detail. I have a E90 335i LCI which might be different in wheel offsets compared to the non LCI if doing all the M3 arms. You probably could of brought another 135i for the price of this rear end overhaul its crazy how much this stuff costs. Get swaybars if you're tracking it the subframe will need to be dropped a bit.

[@jake_spence]

I wish I would've known that about the rear swaybar. Oh well, I still enjoy the results of these modifications. Maybe I'll add a swaybar in the future. Thanks for watching!

Your control arms are upside down. The ball joint end should be at the knuckle and the arms should be curving downwards like a U.

Great video and some great parts going on this build. I want to upgrade to the m3 goodies on my 135 so I’m very interested in how much better it rides now.

[@jake_spence]

It's been great so far! I haven't been able to get out on the track since installing these parts, and I feel like that is where they will shine. If you're still on original suspension and bushings, you will definitely notice a different with new upgraded parts.

Old Video but it was impressive how you got the sized bolts out. Did you use a chisel ? I spend a eternity to cut them out with a jigsaw.

[@brianstewart7476]

Hi, Jake. I have a 125i, I have a done a 1m oem panel conversion. I am thinking about doing the rear hub conversion that you have done. To bring the wheel in a bit to help with clearance. Do you know if the 3 series hub wheel bearing conversion that you did would fit the 125i axle shafts. I’m not sure if the groves on the axle spindles would marry up with the 3 series hub/wheel bearing.

[@Sasa-yd7to]

hello congratulations for your excellent work and all the changes you have made. I hope to learn something also because I don't speak your language I write from Italy I own a BMW 135i E82. I had a question even if I sensed that you said it in the video, but if you could write me in detail the sizes of tires and tires of both axles that you used including offset and if you used spacers, but I don't seem to have seen any . I am very grateful to you if you help me. Thanks so much.

[@Stroker396]

Very nice. I would love to do the 15" wheel conversion brakes to my E60 535i wondering if there are enough similarities that these parts would work???

[@jake_spence]

I'm not too familiar with the 535i :/

[@S58AJ]

Sick work....how you liking they vibrating tho? What motor mounts you got. I ripped through 2 different ones after i went solid everything. Now i got solid mounts. Also when you run the slicks i recommend going 0 camber in the back or you will eat up slicks and lose traction.

[@jake_spence]

I haven't really noticed any increased vibration. I have new stock motor mounts. I will keep an eye on everything, but I think since I have poly trans and poly diff mounts, it'll be more forgiving than completely solid. We tried getting camber as close to 0* as possible.

[@karl1608]

Proper Job ! Pretty sure your Guide Rods at rear upside down ! ;)

[@davispaul82]

This is a great video. Would it be possible just to replace the rear hub and bearing and keep everything stock back there so I can run 90 wheels in the back? Also I wish you would've painted your subframe.

[@Grimsyko]

Love the car! Question Jake I have a 2011 135i, if I were to do the hub conversion to a 3 series one for better wheel Fitment would I need to change any other stock parts? Basically would I be able to just order the the straight part of the list you provided, I know you did to be able to fit 15inch wheels. My issue is I rub a little bit with in the rear using 18x9.5 wheels.

[@CRSwift]

Great build, just noticed youve put the front control arms on the wrong sides, the front control arm should be inverted (bow down)

Nope, no additional NVH or noise from the solid rear subframe bushings. The newer F-series BMWs don't even have bushings, they're directly mounted to the chassis of the car. But if you use solid differential bushings, you will feel some vibration and noise.
