If the suspension is the same as the bellett, you can use Mitsubishi scorpian discs/calipers on the front.
I don't think the 117 was based on the Bellett chassis (like the later Piazzas were based on the Geminis). Even those tend to be visually similar, but not always identical (at least for the first generation Piazza). Maybe the 117 was based on the Bellel or Florian chassis, but I know less about those than the 117. If not, it was a from-scratch creation.
The Bellett has a swing axle rear suspension with coil springs on angled trailing arms. The 117 rear suspension is solid beam with leaf springs.
On the front, both have upper and lower trailing arm over a spring and shock, but the Bellett looks to be mounted perpendicular to the frame, and the 117 arms are angled back toward the rear of the vehicle.
