[LOWDOWN]

Given: An LS7 and an LSA cost about the same, in the crate.

Problem: How to price a Z/28 below the ZL1:

Z/28 BASE Content

- Use 1SS/1LE for content, which includes HD Tremec/HD Axles/Forged 20s

- Substitute "wet" LS7 for LS3...weight-neutral

- Add ZL1 Rear Diff/Carrier...20 extra lb.

- Add ZL1 6-piston Fr. Calipers/Rotors...weight-neutral

- Batch-build with 1LS (non-6-way power) Cloth front seats + brackets...save 10 lb.

- Substitute Michelin PSS 285/305 tires...save 8 lb.

Solution: Z/28 weighs 200 lb. less than ZL1...220 off the nose...@ less than $50Gs (or 10%+ less than Base ZL1, or = BOSS LS)

- 2SS (inc. 6-way power seats) available as option
