Well after 3 months of driving the car around I thought I should post my findings with the ESS VT2 kit and provide some helpful hints for those who have either put their order in or are still deciding.
First let me start off with things that concerned me (little but were worrysome).
Driving the car at WOT I heard this bad rattle sound, it only happened when pushing the car hard, I have attached a video and you can hear it pretty well.
First I thought I had a bearing going bad in the SC itself so I babied it home and decided to sleep on it and dig deeper in the morning. Next day I decided to rev the engine to 7k rpm as this is a belt driven system and it should reproduce the noise but it didn't
soI started to mess around with things in the engine bay, this is what I found.
There were two hoses on the passenger side that were loose which is not a bad thing but made a noise when driving around.
Also due to there no longer being an airbox on the driver side the wiper fluid filler was just floating around with no support
, had to fix that too.
Lastly the thing that was making all the noise was these two lines that were hitting against the heat shield, I went ahead and drilled two holes and zip tied them to the plate
no more rattle.
I spoke to Roman at ESS and gave them my feedback and hopefully some of these adjustments will come in the next kits but just incase they do not then look for these certain areas first
Other than that the kit is awesome and drives fantastic, actually just like a normal M5 when your not pushing it.
If anyone has questions just fire away
