Looks like a great combo.
Maybe think about M calipers on back with 911 e-brakes and tangerine conversion kit. Not very pricey, especially with your parts supply and would compliment the front brakes.
Or get 914-6 calipers, keep the 914 e brake and get the larger caliper pistons 38 mm, same as m calipers.
Great suggestions on rear brakes. I am not familiar with the Tangerine kit. I would imagine 914-6 calipers would be tough to find.
Since my trailing arms have already been powder coated, my 914-4 calipers are finishing up restoration at PMB and I already have the 911 non-vented rotors that have been turned by 3 mm, I am inclined to keep that setup. Since the car will be primary street driven, other than the visual and cool factor, how much downside is there to the stock 914-4 calipers?
I have stock 914-4 calipers on my conversion car with M calipers on the front. It’s a narrow body with 3.2. My GT car will get S calipers on front and 914-6GT calipers on the rear. The GT calipers are just expensive M calipers with an e-brake. My Suby 3.2 car has M calipers f&r with the tangerine kit. When everything is finished I’ll let you know what works best(for me) lol.
