Race Car V4.0 - Ground up

[D_Eclipse9916]

Finally back from the Body Shop! Had some fun "driving it" from the bodyshop back to MachV being towed behind a golf kart on public roads. Got some fun looks (and a honk).

We picked it up Tuesday night and was able to knock a couple hours worth of work out.

-Dropped the rear suspension as a unit and welded up the RTAB (what failed on my previous car)


-Mocked up the brake lines to the rear.
-Assembled the front suspension and brakes. What a fiasco!
When I replaced the rear wheel bearings, it turned out the car had 325i rear trailing arms, which require different wheel bearings than 330i (and then M3 has different ones too). Well based on this information, I had assumed the front spindles were 325i, and since 325i and 330i were interchangeable, I got new ones since I was concerned about the spindles being straight.

First try: Swap wheel bearings on new(ish) 330i spindles. Doesn't fit AKG Control Arms made for 330i...what?
Measure old arms and they have larger hole. Did I get 325i spindles? Do some research and nothing makes sense.
2nd try: Start researching AKG arms, they are made for non-M, everything should fit. Did I get some random 325i low production spindles?
3rd try: reem out new spindles, but measure different thickness for reinforcement of low control arm and calipers, make me nervous. I take a quick look wondering how thick the M3 spindles are off the car and its surprisingly similiar...Wait a minute. These look familiar.... Measure out and turns out TCKline used M3 front spindles. Okay well my AKG arms are made for Non-M spindles and so are the brakes..or so I thought. Brakes bolt up and control arms bolt up. Yes the control arms made for Non-M dont fit the non-M but miraculously fit M3 spindles (our luck/not luck?)

*Sigh* So basically we assemble it all together after figuring out that mess that ended up eating our entire night.


Closing up shop, oh look who's here too?
