Yeah thought that might be a bit of a deal breaker. Been meaning to swap in a stock diff cover, but I don't really drive my M3 too much on the street anymore, so it's not high on the priority list.

Nice, the front seats came out great!



You're welcome to drive mine whenever. Decently similar to yours. Only big differences I can think of are poly diff bushings and the springs.

Thanks, yeah the seats really worked out. I ended up having to modify the EEPROM data in the switching console to get all the heat levels to be the correct temp, but it's all gravy now.

Those diff bushings really invalidate the test I remember that you have more diff whine than I do and I'm sure it is mostly due to the poly bushings. Diff whine is my main concern for this car..

Install solid subframe bushings (*maybe, I need rides in cars*)

I've been putting off starting this thread for a long time, and each time I work on the car I wish I had a place to drop updates. I'll start off here and fill in the details as I go along.

Background: I grew up working at my father's indy BMW/Mini shop, owned many BMWs, several Porsches and one 50 year old jag that's now electric. I'm an engineer, a couple different types by degree and trade and can't seem to leave my cars alone.

I was previously driving a '21 Taycan cross turismo 4s, which is a fantastic car, but it just didn't have the spirit of something fun and playful like some of the older cars with lower limits. I'd toyed with the idea of building an s54 e46 touring for years, and finally decided to plunge in. I called an old friend (Kaiv on the forums) who has gotten pretty good at these and asked about whether he knew of a clean black chassis wagon for sale. *Fun fact, I used to program some of Kaiv's s54 swaps some ten plus years ago, when I owned an e46 M3* Kevin did me one better and hooked me up with one of his already swapped and BAR'd cars from years past! It needed a lot of work but the engine and driveline were all in great running condition, and it saved me a lot of effort.

I picked it up in May this year as a black/grey swapped touring, lowered on soft springs (mostly bump stops) and it needed a significant amount of work to make it proper. Many invested hours later, it's now black/natural brown and has been completely gone through and drives about as close to a new e46 as any I've driven since I worked on them when they were new. It's my DD, so it must be smooth and quiet.
