evokid Posted January 3, 2019 Report Share Posted January 3, 2019 I'm sure this has been asked b4 but i cannot find it on search? I'm sure i read it fits with some modifications, but anyone tried it? Results etc? Just feel the Rear Bumper on mine need a bit more depth. Would obviously then have to route and install some quad pipes too. Link to comment Share on other sites More sharing options...
momo Posted January 3, 2019 Report Share Posted January 3, 2019 M3 has flared rear arches. So if you fit the bumper, the tops where it joins the arch wont line up Link to comment Share on other sites More sharing options...
evokid Posted January 4, 2019 Author Report Share Posted January 4, 2019 (edited) Few done it, just think i read somewhere you may have bigger gaps between rear arch and bumper line like you said... https://forum.e46fanatics.com/showthread.php?t=768398 Rear Bumper: Difficulty: 6/10 DIY: Probably not. Part Numbers: - Re-Bar: http://www.realoem.com/bmw/showparts...06&hg=51&fg=15 - Bumper: http://www.realoem.com/bmw/showparts...19&hg=51&fg=15 This has only been tried a handfull of times, but this mod is usually accompanied by a widebody. Since there's such a difference between M and non-M rear fenders, this bumper is a good inch or two too wide. To fit this correctly, you'll either need to do some hardcore molding and reshaping of the bumper, or a custom widebody in the rear. If you can deal with the bumper flexing and creating numerous noticeable gaps, then I guess you could do it without modifying anything (and only stretching the sides of the bumper in). Again, this mod isn't highly recommended unless you're serious about modifying your car. Safe Alternatives: - Hammann GTR - Mtech2 - OEM Aero Kit (a.k.a. Mtech1) - Various rear addons Edited January 4, 2019 by evokid Link to comment Share on other sites More sharing options...
momo Posted January 4, 2019 Report Share Posted January 4, 2019 Pretty sure you can get M3 style diffusers if it's the quad exhaust setup you're after. But it means you have to cut out the spare wheel well unless you get one of those cheap quad jobbies where the right of the quad setup barely gets any flow. I didn't think they were any deeper? I thought the only difference really was where it meets the arches and the quad diffuser. Otherwise it was the same size as a regular sport bumper.. No?

I think that'd be better way to go if can get the diffuser? This is about best style quad work around i've seen.. Although still not ideal..

momo Posted January 5, 2019 Report Share Posted January 5, 2019 (edited) Plenty of options on here: https://www.mstyle.co.uk/bmw-3-series/e46/exterior-styling/rear-bumpers-skirts-splitters-accessories.html I remember seeing a E92 335i style diffuser too once but can't find it now. I think that looked better as a non-M quad setup always looked to "trying too hard to be an M3" to me.. lol Edit: This is it Carbon https://www.insideperformance.de/en/3er-bmw-e46-335i-look-heck-diffusor-carbon_1272/ Plastic https://www.insideperformance.de/en/3er-bmw-e46-335i-look-heck-diffusor-kunststoff_1273/ Edited January 5, 2019 by momo evokid 1 Link to comment Share on other sites More sharing options...
