JPSS IS Amazing.
Pretty much EVERY obstacle was thrown at us during this rushed build...and still Pete and his team came through.
We upgraded my 2014 SS 1LE with Z/28 aero, suspension, brake cooling, bodywork, and an LS3 heads/cam package...parts were missing from packages, others shipped late...and somehow, it all got done, dyno-tuned, meticulously aligned, and on the road to the Camaro Fest in 2 days time. And if I asked nice...they'd even let me turn a wrench or two.
I was so pleased, the car went back to JPSS the next summer for a visit and a ZL1 brake upgrade.
