New to group!

Hi all!! I've been sitting on my early build, higher mileage M3 the last few years and im putting it back on the road. It's a pretty basic spec, carbon schwartz over black nappa, big 3 done, zhp steering rack, eonon cd headunit, e9x comp wheels, sunroof, original 3 pedal car. Owned it going on 5 yrs now. Recently added oem euro front bumper, completed carbon front carrier conversion and refreshed the nose with new headlamp lenses, grilles, badges, etc. Just saying hi to fellow enthusiasts.

Is there some kind of secret to getting this tail light trim on?

For the love of all things holy, ive been trying for an hour, putting a ton of pressure on it and I can't get it to fit. Brand new OEM cover with aftermarket lights, but judging by how difficult it was to remove the OEM cover, I'd imagine it was similar to install. Any tips?

Vanos rebuild help

I’m currently in the process of rebuilding my Vanos and I may be having some trouble with the cam alignment. I am following the beisan DIY instructions, retarded the cam timing and removed the Vanos. I realized the exhaust hub isn’t protruding as much and the intake side or in the photos. I’m aligned at TDC but the alignment bridge isn’t lining up properly (see photos). I’m trying to figure out if I have done something incorrectly and how to remedy. Would like to hear from people who have done this job before.

I can get the pin to align with slight lateral movement of the bridge. Intake does in a bit easier than exhaust but the exhaust hub still doesn’t protrude at all like the intake hub

Had this happen last night

So I woke up today to find my car like this. Yay me!! Seeing as I don’t have the time or money to put into fixing this, is there anyone here who would be interested in a parts car?

Everyone on my last post asked for airbox videos, here’s an average clip with an above average backdrop

Only had the stones to ask my wife to stand on the side of the road for one flyby video 😭 A lot of people asked about drivability with the alpha N/airbox, and having just driven Boston to Acadia with all sorts of traffic and small towns, highway driving, and everything in between it checks all the boxes! Exhaust is stock with the exception of catless headers, so that plus the airbox and tune makes this thing a blast💥

Knocking noise?

Hard to tell in this video but it seems like a slight rubbing or knocking noise. I can’t pinpoint it but I don’t remember hearing this until today. Had the rod bearings done about 600miles ago. The fan isn’t touching anything. Any thoughts?

Finally sitting and sounding exactly how I wanted it to 🙌🏼

15mm spacers up front, 10mm in the rear, Turner CSL Airbox w/ Alpha N tune from Kassel. All installed at Wile Motorsport in Mass (the owner just placed third at the Mt. Washington Hillclimb behind a Subaru rally car and open wheel kit car in his front-mid-engined B58-powered E36, give it a Google if you haven’t already seen it!)

BEST Brakes discussion/question

Hey all,

Doing a massive refurbishment of the car and major upgrade on the geometry. I want to upgrade the brakes as well to the best for sporty road use. Always a breambo guy but last few years I am of the opinion that AP racing are better for the e46, but im not caught up and getting into reasearching breaks right now (hence this post as well). My mechanic who I trust says willwood.

Money not an issue within reason.

What do you guys think?

Shop turnaround time

Shop owners, how much time from when a customer drops off a car till you get your hands on it ? is 3 weeks a sign I should just go pick it up and take somewhere else? I mean I’m pretty understanding, but no communication and the car is just sitting there is not a good look. How long are you all waiting for your cars to get touched at the mechanic shop?

Currently have the front end off my e46 m3 what should I look into replacing?

2004 m3 wont shift into gear .

TLDR: I replaced the brake light switch and now the car shifts in gear but wont move. I have an smg and the transmission light but not this time.

So ive had the transmission light for a bit it comes and goes and comes when the car is warmed up (after driving for a bit. This part is important)But then it was gone for a momth and then came back. At a full stop it wouldnt shift from 1st to 2nd. Even in 1st it would have no throttle and soemtimes it would just go into N. Id have to turn the car fully off and restart it before moving. I had a brake light also. Last week the transmission issue happened again so I parked it and today I tried changing the brake light switch cause I heard that might just be causing it.

Alas, I changed it and turned it on and put it in gear (after waiting the mandatory rev drop and temp needle moving up) and the car wouldnt move like the transmission issue from before but there was no transmission light (you know the yellow gear). Usually that would come up when the car was warmed up. So i don't know if i screwed up the brake light switch replacement or if its my smg cooked.

I am planning on getting the manual swap anyway but I was hoping I could at least drive it to the shop.

What's the best way to clean this up?

UK based. I have to replace the diff rear cover bushes and want to clean up the outside. What's the best way to clean it? I see some people also paint them. Not sure if I want to paint it but if I did what paints etc. are best? My Dad used to say that with some parts the dirt and grime actually helps stop the metal deteriorating.

Another question is it a bad idea to clean out the inside yes or no? And if yes, what's the best way to clean the inside.

Thanks in advance for advice.

Dream Car obtained

Never thought I’d be in a position to purchase one (let alone find a clean one in New England) but I got the steal of a lifetime over winter. Had to travel hours through a snowstorm with a truck and u-haul trailer, but for $11,000 I am not complaining. It’s everything it’s supposed to be.

Convertible Subframe

I opted out of the subframe reinforcement on my convertible. There’s no signs of cracks or weakness and it’s a convertible.

I’m having the Vanos and Rod Bearings done and couldn’t stomach the additional 9k for the subframe.

What’re your thoughts? Can I keep an eye on it? Is the convertible reinforced enough already?
