E63 is a GT car and pretty damn good one while at. Not saying it can’t be tracked but probably not the best platform to start with.
MCS is no joke, but it will take time for them to build your system. I'm heading out to Buttonwilliow this weekend to run my ST4/Spec e30, but I will have my e60 at the track. I just swapped out my worn PS4S for AD08s on the e60 -- should be interesting on the MCS!Did some research. SSR Competitions is U.S name, it is actually SSR Type-C. This model is no longer available and I dont see they have our pattern. According to this website, the 18x9.5 weight 17.5 lbs so it is not close to 16 lbs.

@Fiftytwoeighty: Your E60 looks really stable in corner! I am going to call MCS next week, hopefully they dont have a super long lead time. Dinan 19x9 / 19x10 is a good one but I have heard bad story saying they are not strong enough, not sure if they will survive the pothole in my area...
BMW 763M 19x9 / 19x10 cost less than $4000 per set, weight only 20.75 lbs and 21.8 lbs, that's pretty impressive for OEM wheel (I hope they are a bit stronger). It however will require 20mm / 25mm spacer to reach OEM mounting position on E63, a bit annoying.
Well, I really want to keep a comfortable ride, those changes will make tire and wind noise way too loud?That's a very nice weight saving. Hope the lithium battery does the job for a long time.
On my E46 M3 race cars I ran a Shorei lithium battery which was 5lbs total including the bracket.
Have you looked into removing sound deadening from the body? Might be a good 20lbs if not more, and it's free..
