So far I've added a JB4, hard charge pipe (mine blew up), Megan racing front sway bar (still need to install the rear), high flow down pipe (still need to install), Winmax W3 brake pads (ordered), and OZ wheels with 245 Re71R tires. I'm racing some autocross now, and I plan to start doing time attack. We will eventually make it a track only car--I think. My plans are to get an LSD (I'm thinking Wavetrac), delrin bushings on the rear subframe, and Ohlins street and track shocks. I'll get race seats, roll bar, and aero later. What do ya'll think? What should be my priority? What am I missing? I have a LOT to learn about the other suspension components, since my bikes didn't have them. |

People seem to like to reference the M3 having solid mounts, but the F80 subframe is better reinforced than the F30.

2 deg rear camber is perfect; I like a bit more in front on these cars... 2.7 - 3.2 is a good range (roughly 1 deg more than rear)

Curious where that feedback is coming from... lots of e46/e9x/f8x M cars flying around track on 18x10 wheels and 275 tires up front. A square set of 275s is sort of the standard track setup for the M guys.

Sounds like you're on the right track, and your mod list sounds great. Being that you've already increased power, I'd say that puts the priority squarely on grip, traction, and car control.... so an LSD, Ohlins and rear subframe bushings are all top priority. One thing I didn't see you mention is camber plates... are those on the list too?

I’m going in for alignment next week with adjustable superflex bushings next week along with new tension struts and a new 4 wheel alignment 😎

So, we got the front sway bar installed and then raced autocross this weekend. The car handled a lot worse than when it was just stock, but I'm not totally surprised since I didn't get the rear sway bar in yet or upgrade the suspension yet. I want to install the Delrin rear subframe bushing when I do the rear sway bar, but I'm not having any luck finding the special tool I need to R&I the bushings. Do y'all have any suggestions?

If you're going camber plates anyway, the biggest benefit of the F8x control arms is the spherical bearing in the LCA that replaces the mushy bushing in the F30 LCA. I think it's worth it, but it's certainly not a dramatic difference. More like a first step down the longer road of dialing out all the suspension comlpliance (tension strut bushings, and the rear multilink arms would be the next step).

https://photos.app.goo.gl/pyyMZVtqTu8voQTo9 You will need a 3" threaded pipe and a cap (receiver). 4" inches in length if possible, but 5" or 6" will also work but you will just need more space. 1/2 inch threaded rod cut to about 16" or so (depends on the length of your receiver) I used a 6" threaded pipe and needed about 16"-17" of 1/2 threaded rod to do the removal and install. Note the extra length is for the install. You will need a way to "lock" the rod in place while driving out/in the bushings so I recommend using a double nut on either end (I put double nuts on both ends for flexibility in case I ran out of *******. you will notice in the pic I use a long threaded collar to apply pressure at the base of the cap. this is so you use the maximum amount of threading to prevent stripping of the 1/2" rod. It is in your best interest to lubricate the threaded rod with wd40, pb blast or whatever derivative you have access to. After the third bushing, the rod snap... A word of caution. should you choose to perform the installation yourself, you will discover that male pattern baldness is NOT hereditary!! You have been warned! I found that the simplest way to remove the old bushings is to burn them out. the exterior of the bushing is lined with plastic so you just need to melt off one section to release the pressure and then hammer it out. God help us all. |

How easy is it to get the Delrin bushings back into the subframe? |

I just lowered the subframe and left the parking brake cables attached. it was difficult to get them in the way i did it eventhough delrin is relatively compliant for what it is. still doable though. After burning out the bushings, I washed out the subframe bushing "seat" with soap and water and a dollar store brush. WASH IT GOOD! then spray it with kroil, PB blast or whatever. That seemed to make it easier to press the bushings into place. I've got one more to do. If anyone is interested, I can shoot a short video of what i'm doing. You may need to bare with the fact that I am not a cinematographer and do not care to become one. There is a bushing tool availble for not too much money that can be used. I was just interested in making my own to test and learn. |

Tire temp variances across different wheel widths were not provided so I resigned the information to a lack of testing and hence, knowledge...I believe their (no names...gonna be nice) concern is having to deal with the risk of fitment complaints and wheel returns. Their reference was never optimal temperatures, it was always about tire/wheel rubbage. It was a risk-absolving answer... Even at 9.5" wide, I am facing alot of resistance until i explain my measurements which is usually met with resounding, confused silence... |

https://www.newtis.info/tisv2/a/en/f...nsion/HKiFvVNT https://www.newtis.info/tisv2/a/en/f...nsion/HKeT7vfk I believe you can convert the ISTA tool part number by prefixing it with 8330. For example, if ISTA referenced tool # 0492397. https://www.newtis.info/tisv2/a/en/f...ension/5OHeawD You would convert it to a BMW part number by changing it to 83300492397. https://www.getbmwparts.com/oem-part...10-83300492397 |
