So the 374mm rotor caliper showed up today. As I stated earlier, this project is dead in the water for me because of the lack of brake pad options for both the 374mm rotor caliper and the 395mm rotor caliper (same pad part number) however, here are some measurements and photos...
Perhaps the...
Nice. Very similar to mine. He is running less boost but more timing, which makes sense on the lower compression 21+. Plus, I also asked for less timing because track use. I peak at 14*. Usually 1* of timing is about 10whp.
I dunno about a dynojet reading "low", It's a dynojet on STD...
Hhaha yup. I have many stories and I too used to be an instructor.
I had an instructor years ago non stop complain about the speed I was carrying through the corners. Told me to pit after the second lap and then literally screamed at me about how I was driving too fast for the car. When I asked...
Also just noticed something VERY interesting. Either a different rear differential cover or a totally different rear differential. The cooling fins are totally different and in this photo, it seems like it hangs much lower than the current diff!
It's not a full fat ///M diff as the g-series M...
So.. after looking at the brake photos more. These are 100% the 395mm sized G-series calipers (850i+) with the G-series ///M full fat 295mm floating rotors. The 395mm calipers have that extra ridge at the bottom compared to the 374mm calipers. You can see they even ground off the ///M casting on...
AFAIK the OTS maps have the limitation upped/removed. If you start from scratch, not OTS (custom tuning) then you need to up/remove them in the rom.
There are 20+ limitation tables. Some of them make the car up/down shift crazy aggressive. I actually had my Supra shifting insanely aggressive...
So I did some more digging on the brake pad size for the 374mm rotor calipers. They are indeed a different size and even worse, there is hardly any brake compounds available. Some EBC (yuck) and one Pagid.
So, unfortunately, for my needs, this makes this project dead in the water for me. I'll...
@lucky phil my little Aussie man, nothing eh?
Let us at least talk about pebbles in the rotors! Come back to me my always wrong but always calling me out for some reason huntsman spider slaying brother!!!
At least post more photos of your 1982 garage! Please, I love it.
Do you have experience with this exact setup? If you do, why haven’t you shared the knowledge? I know this fits with oem m340i 18”. That is not what I am after with what I am testing.
Please feel free to do your own testing and let us know. If not, it’s all talk and chest flexing. Which is...
