Specifically designed for Midwest-Bayless! - SPECIAL ORDER ONLY.

This is a set of four American made, lightweight forged aluminum pistons, suitable for all Fiat or Yugo SOHC racing or hot-street application (1300 or 1500).

We use these exact pistons in our Midwest-Bayless Fiat X19 race cars.

This particular style has a slightly taller compression height than stock, and a small, flat dome which produces 10:1 compression with a stock North American head, and over 11:1 with a milled flat North American, or Euro-style head.

11:1 compression is the exact target for SCCA Limited Prep production racing.
