Actuary's E46 M3 ClubSport build

[Actuary]

t's great to finally start sharing info on my E46 M3 build. Like many of the M3 owners on here, building a CSL+ version of the M3 has been a long time plan. I loved the M3 CSL look with carbon roof, ducktail and m3 bumper wrapped in silver grey. So i sought out the cleanest Silver Grey I can find, even with putting SMG on must have list. After searching for months, on July 2010 I bought a 2004 M3 with 40k miles. Coming from an E36 M3, the E46 felt like an improvement in every way. Shortly after I started tracking it at Watkins Glen and Lime Rock. It was an amazing experience to have a car that I can drive to work, go to the grocery store and drive/at/from the track. What makes this car much more special for me is I drove my pregnant wife to the hospital and brought our baby girl back home with it. I hope I never have to sell this car.

Shortly after pick-up Jul 2010

Here you go! You'll need to scroll to the bottom to see info/package/pricing for the E46 M3/CSL brake duct. https://a-concepts.de/en/references/

I got the brake duct perhaps 5 years ago and so far no issues on street or track, calipers and rotors stay cool. I think this is probably one of the better options for folks running CSL bumper.

KW Clubsports 2-way
Got these at an amazing deal back in 2019 from ECS. It was between these and Ohlins R&T. The price that I got these with the cash back offer was a no brainer for me. My experience with the KW has been amazing. Rides well in the street setting and track. I use the same settings as the CSL guys recommen in CSLregistry.

Road Basic Setting
Front
Rebound 6 clicks
Compression 1 full turn (6 clicks)
Rear
Rebound 12 clicks
Compression 1 full turn

Ring Dry Setting
Front
Rebound 6 clicks
Compression 0,75 turn (4 clicks)
Rear
Rebound 9 clicks
Compression 0,5 turn

Just wrapped up the window trim in gloss black. The bottom trim pieces are new OEM gloss black, very well priced compared to the matt black. For the top (A to C pillar), i changed the OE looking rubber piece from https://nam3forum.com/forums/forum/m...im-replacement and wrapped it in gloss black. I couldn't justify 2-3k per side. I think it came out pretty good. If it lasts, i don't mind paying for a rewrap down the line or full respray.
