What rear caliper adapters did you use? Looks like it all fit together perfectly!
These are rebuilt e46 325i calipers. They fit with adapting brackets from SRS concepts. Completely bolt on, even the brake line. I will post some pictures/measurements of the factory e30 and e46 caliper side by side. The piston is much larger on the e46 unit.

Wasn't sure if the extra $150 was worthwhile when I just drive on the streets? What have you had success with? I wan't impressed with the Hawk HPS.

Do you care about noise/dust?

Starting the 5 lug conversion on the front end using the IRP kit, e46 bearings, and e46 325i brakes. Threw on some new sway bar end links while I was at it since those were crusty. I'm still waiting for the carriers to come in the mail. I will update with some comparison of the calipers, the piston diameter is quite close from e30 to e46.
e30 (260mm) vs e46 rotor (300mm)
e30 Hawk HPS (which are trash) vs e46 Textar, not a huge difference. The textar is taller and wider.

Finally got the carriers, so the calipers are on. Still need to get some anti-rattle clips. The e46 caliper piston is about 5mm larger than the e30. On another good note i've got the flex sensor harness run through the firewall and wired in, I will be working on mounting and plumbing that in soon. It's going to be badass not ever worrying about the fuel you put in the car. With the flex sensor the ECU will automatically adjust the VE table and ignition table for ethanol %.

This might be on the few cars that would actually benefit from running one those Rocket Bunny Kits to fit enough tire under it.
while more tire is sweet, the thousands of dollars he’d spend on fiberglass/finishing/paint/new wheels/new tires, an aftermarket traction control setup that works with the terminator x would be cheaper.

terminator x
You realize I don't know how to stop myself...?

I've considered just getting some fender flares but, I really want this car to look like a mostly factory e30 with some minor mods. So the only future option will be to go in...

For now and the foreseeable future, the TCS is my foot. I can't wait to see how these new tires (and the axles) hold up.
Minor updates to come soon as the flex sensor mount will be arriving in the mail today.

Managed to get the flex sensor mounted under the car. I need to get two 6AN ptfe fittings to finish up the job (had the extra adapter fittings pictured laying around). I also decided to test my local premium 91 gasoline for ethanol content and contrary to what I've read on the internet, there is no ethanol (as advertised). The internet was saying even the premium-no ethanol still had some in it.
Knowing the ethanol content is important because my current ve table is based on this fuel. The flex sensor should read this fuel as 0% and my will not add any fuel to compensate based on the flex multiplier table. Once the sensor begins reading ethanol %, the ECU will multiply my base ve table to administer the proper ratio. Hooray for being able to use any fuel available.
The struggle of dealing with someone else wiring harness.....

You are doing great!
Thanks bud!
I forgot to mention, the flex sensor is placed on the fuel return line which is 6AN. The other line (feed) is 8AN.
I have a question for the community. I have been really thinking about going to a fuel cell. What do you recommend and what should I look for?
This is what the flex table looks like in holley, note that I stole this image from google images and the table is not set up properly. There is another table just like this that will subtract or add ignition time per the ethanol %. The possibilities are endless... As a former mega squirt/tunerstudio user, Holley is just way more user friendly.

Personally I would not get a fuel cell. The location of the stock tank is in a great spot. If you’re worried about starvation, just get a surge tank setup.

I had planned on adding a surge tank once I run out of fuel pump. Since I've had to modify the return line because it doesn't flow enough and the factory tank having old rubber (not ethanol friendly). I think its a better and safer option to transition to a cell. I do agree @KaiserRolls, the factory tank is well positioned in a safe place and low center of gravity. Perhaps it may be worthwhile to pull the tank and modify it to fit dual pumps. There is still that venturi/return line that is responsible for transferring fuel from one side to the other. How do you get around that venturi?
