Hi AlecX5,
I had already said in my previous post ,that your fender kit is not stock 4.8is.Overhere they are just called Special Edition flares kit but have same OE part #.I know it comes with the front flares as well...I also know the difference between this and the stock 4.8is kit...But I already said all this in my reply to Sapphires question

I thought I explained quite well all the differences

Nope,I forgot to add that the rear bumper side inserts are also different!I personally prefer them over the OE 4.8is inserts,especially as each insert ,when bought separately,cost only USD20.00,each,as opposed to approx.USD $174.00 for each 4.8is insert .
I fitted same kit as yours recently on mine and I know it only fits cars with ARBs.
You got a winner there.:You got really good value for money with that "special edition"(Le Mans) flares kit,especially when compared to a full 4.8is kit.
Your car looks great and that kit transformed it...Congrats
