Kits:
1. SS lowering kit (springs/shocks-84188726) + handling kit (swaybars/front links-84242386)
2. SS 1LE suspension kit with MRC cal update (not applicable to my specific car)
3. ZL1 1LE suspension kit (both 84352121 and 84352119)

I'm leaning toward this combination of parts to get as close as possible to an SS 1LE: SS lowering kit (springs/shocks-84188726) + handling kit (swaybars/front links-84242386) + SS 1LE wheels/tires

However, before making a final decision, I'm really interested in you and your team's thoughts and recommendations and what the performance #s would look like between the different options.

Existing literature states:
- SS lowering/handling kit (springs/shocks-84188726) + handling kit (swaybars/front links-84242386) provides a 1.6s lap time reduction on Milford Proving Grounds Autocross course.
- ZL1 1LE combo noted above provides a 1.8s lap time reduction at Milford Proving Ground NE course on an SS.
