Honestly solid subframe bushings should be high priority. Solid subframe was on the e92 gts, f10 m5 and on all the F8x M cars. It eliminates so much slop and rubber banding in the rear. Lots of people feel this symptom I describe and think coilovers are the solution. I have never heard anyone go solid subframe and regret it. Do it. Labor is a bit much and it's not a sexy part but man will it improve your car.

The Leroy trailer has arrived and is assembled. Going to wire the car tomorrow. I'll repost a refresher on the tail light wiring diagram/instructions that I've found here in the forums. I'll get some cage pictures up too as requested. Here is a sneak peak of the Leroy Paddock250. 1 man assembly took about 70 minutes (including attaching tail lights and storage box which is not pictured here). More photos once the sun returns.

Couldn't be happier with the Leroy Paddock trailer. I put a handful of miles on it today and it performed better than expected with it's mini coilovers. No bouncing. No seesawing. Tracks dead straight.

For those curious about trailer harness wiring, here is the wiring assignments for e82/e90/e92:
Driver's Side: grey/yellow= brake blue/green= left turn grey/purple= running lights Passenger's Side: * blue/brown= right turn For the ground I used the established ground point for the tail lights behind the trunk cover on the rear driver's side wheel well (photo below). |

So what's the long term goal of the car? On a side note regarding passenger occupancy sensors; you can always try BimmerGeeks; they can remote into your laptop while you are connected to the car and then code out those sensors. If you haven't done that already, I'd also look into common traction control value adjustments and code out the caliper adjustments to get consistent brake pedal.
Nice build! |

So as of right now I am still lit up like Christmas tree on the dash. That is great info to know about remote coding. I did not know that was an option. I'll have to do some more research to determine exactly what I need on my end as far as software and cables. I had contacted BrenTuning (local to me) but they will only do coding as an add-on to a dyno tune because it is too small of a job :/ I've been looking into coding options for traction control as well. I've been using the sticky in this forum and the write up below for reference. https://www.google.com/amp/s/bmw135i...k-nannies/amp/ Last edited by Dr1; 09-16-2017 at 08:45 PM.. |

Highly recommend them! Has the car been on any tracks yet or still in the building phases? I think a lot of 135i cars are running a bigger tire setup than 245s and some even staggered. |

As far as coding goes, thank you for the lead in bimmergeeks. I am in contract with them now. Much, much appreciated! For tires sizes, I have been running staggered 235/255 for a few years and decided to move to a square setup for better rotation. I haven't put the square setup on yet as I am still using up the last of my 235/255 tires. |

Seatbelt coding for the warning light is not available (or possible) so the transplant of the factory receptacle onto the new seats (5 minute process) was a good idea for my application. Either plug your factory belt into the receptacle behind your new seat or order a dummy off eBay and leave it plugged. Also of note, I also installed the Whiteline RSFB inserts as a stopgap ($45 on Amazon) until this winter/spring when I go for the Turner solids as recommended above (actually everywhere). Whiteline insert tools needed: - E18 female Torx (subframe bolts, tighten to 74 lb-ft) **most off-the-shelf kits stop at E16** - socket extender (if your E18 socket is "short") - 15mm socket (diagonal chassis brackets, good'n tight) - 19mm socket (x-brace brackets, good'n tight) - 2 jack stands (remove rear wheels for install) - floor jack (to raise and lower RSF via the diff housing) - no air tools? use breaker bar/long ratchet/short ratchet+jack handle to "start" the E18 bolts, after that they will loosen by hand My bushings came without lube but were a very "slippery" texture out of the package. I was able to install them easily without any additional lube. There are many posts here in this forum on the install process which is very straightforward and took me just over 1 hour with zero experience manipulating the RSF. Here is some info that was not straightforward in other posts from my perspective. The rear inserts are simple but for the fronts: - Completely remove the single bolt holding the X-brace to the subframe - Diagonal brackets bolt the RSF to the chassis with 2 bolts. Loosen the hard to reach bolt halfway and completely remove the easy to access bolt. This will allow for the diagonal bracket to swing out the way so you can lower the front of the RSF. It was a humbling result. It is one thing reading about the improvement but feeling it? |

Just finished up install of the OMG front splitter (http://www.omgsplitters.com). I posted a DIY here: http://www.1addicts.com/forums/showthread.php?t=1426908

I wouldn't trust a splitter above 120mph without sturdy attachment points, I filmed some runs with and without the subframe attachments and there is a lot of movement. I now have 3 splitter bars and the subframe mount on mine. I'm moving to a slightly larger front splitter in the next month too! Looks great though

I am working on making my own air dam and the plan is to extend it out with an abs splitter as well (form the splitter to the bumper with the air dam). Basically, I will re-create the 1M splitter that has the brake ducts built in. |

The easiest thing to do is to spin the underbody panel mounts around and use long screws through the splitter and under tray to those points. I'm going to mount this eBay air dam that my buddy gave me in between the splitter and the bumper to help with drag. Kinda like the E90 m3 guys do with the Apr splitter + the gts? lip with brake ducts.

Version two uses those same mounting points but more rigid aluminum L that bolts on and have two pieces of aluminum that come down through two small holes in the undertray and bolt to the splitter (with same aluminum L brackets attached on the rear side of splitter) Pretty simple and total cost of splitter with mounts is sub $150

Looks awesome!
What size ARC8's are you running for your square setup with the 245 R888s? Camber specs?
