The performance kit is actually available long time ago. I've bought mine 2 month ago. Trying to put it on non LCI X5. Had to buy rear OEM bumper from LCI.
It consist of 2 kits , which are sold separetly:
1) Front and rear covers , diffusor and rear elerons.
2) Side shkirts
The rear exhaust tips are optional , and they fit kind of weird to fit , atleast to non LCI.
P.S. If anyone want the front part of performance kit , I can sell it to anyone in EU. As I don't need it.
P.S.S. Don't look at crashed 320
, it's a body for a future circuit race car.
