What is the lightest wheel that you can put on a e63s. Does it come to a point on a Vehicle this heavy were that weight wont make that large of a difference?
Saving wheel weight, as with any unsprung mass, will be one of the best overall performance improvements you can make on a vehicle, and a higher ratio of sprung to unsprung weight is ideal.
The diminishing returns will kick in when you start to decrease strength to the point of failure, as well as cost, especially on a passenger vehicle.
I don't have any direct suggestions on specific wheels, but you're on the right track.
I currently have 19" Brabus Monoblocks on my car, an they seem to be made with a lot of material, so I am assuming switching down to a forged wheel from any company would save weight. As you said above @PeterUbers the car is tuned right now with 712hp/ 850lbs torque, before turbo or meth. I dont know which of those routes is next, but upgrading to racing brakes with stainless lines was a night and day difference eliminating the extra weight at each wheel. I love the design of the BBS RI-D, but those are only in 20's and not available for our car.

get the lightest forged rims you can afford or the lightest oem rims that are appealing to you
Just don't want you to compromise safety but your head is in the right place
Advans or volks are a good option but might be hard to find in our bolt pattern. I ran Volk te37's on all my track/street builds super strong and light.
I was looking for something along the lines of very thin spokes, or massive open spaces. the less material the better is the look I am going for. These are the current wheels.
A set of Titanium wheel bolts will save you a pound across all 4 wheels. The cost for a set of 20 bolts is $275.00 and that's an easy low cost way to save unsprung weight.
I would rather tune my car more aggressively than compromise on lighter wheels on this heavy e63
I’d not tune it. The M157’s have weak rods and bearings. Anything over 680 crank hp/600 hp wheel, and you’re playing Russian roulette. I’d do wheels, lighter brake rotors, no rear seats, light battery, non run flat tires are 25% lighter and last 35% longer and grip better, Carbon hood, trunk, lexan windows, run with 7-9 gallons of fuel instead of 19-20 gal > 6 lbs per gallon, etc. also, technically the CLS w218 models are lighter because there’s no dual pano roof and they are “slightly”more aerodynamic. They’re estimated at 50-75 lbs lighter than the E w212. Ironically the newer post 2018/19 models with the smaller 4.0 V8 are heavier. How is that?? Lots more “dumb distract driver” aids that adds weight. The AMG S53GT and r sedan are 4800+ lbs with the V6 six. Sadly it’s a Mercedes, so rod and piston kits for it are 2-5x more expensive than for any domestic high performance car like a corvette, because folks feel they can charge you for the marquis/brand. Same parts but triple the price. So do lots of regular maintenance and other mods but avoid the aftermarket tunes. Especially if your over 35k miles on the odo. I inherited this car but have had other relatives and friends own them. Mine was maintained to a decent degree but I see hints of oil residue under the passenger side cam sensors and a leaky front axle. I don’t have 8k laying around to get these few things looked at and resolved. Others tell me if I am a reasonably ok wrench, I can do a lot my self, and I am. I can do brakes, hoses, plugs, etc. sure I’d love to have 700-800 crank hp and keep up with my neighbor in his 2015 Huracan but I don’t want to worry about a engine well out of mechanical warranty, unless is a company that will write paper on these. I over did it in this post but I just don’t want lots of unhappy miles later. Or sell the car. It is enjoyable though, I must admit. The thrust is like a 757 full throttle to fire wall on a cool day and light load, it just builds exponentially 😁👍. I am in Phx, Az too. I’d love a good rep shop vs the stealership’s. Even a parts Mgr suggested staying away from the dlrs. That’s is for now. Happy Holidays.
HRE has a some nice ones in the flow category (much more reasonably priced than the core lineup) and they are in the 21-22 lbs range, so a solid 10 lbs lighter than stock, per wheel.
Advans or volks are a good option but might be hard to find in our bolt pattern. I ran Volk te37's on all my track/street builds super strong and light.
100% consider Volks!
TE37 Have them for my RX-7 and love them.
There are pictures of TE37s on a white E63 wagon on this forum Looks fantastic.
Has anyone done any real tests to see how much gains if any a lighter wheel in the 1/4?
I'd be interested in seeing that analysis.
As far as light-weight wheels, money is the factor - there are plenty of light weight aftermarket wheels, but the lightest ones are typically $10k+ per set. If you have the standard OEM 212 wheels, they are 27 pounds. So it is relatively easy to find lighter aftermarkets. If you have the stock forged wheels it's a bit tougher.
Anything in Magnesium is lighter weighing just 15-16 lb per wheel in 19” for our cars.
Theres a few places doing them, here’s one: https://www.litespeedracing.com/technology

m157 is pretty stout in terms of tuning and reliability.
Looks good
Care to share the offsets and the tire sizes?
The wheels are +33, but the front is +28(running 5mm spacer so that the center cap clears the wheel bearing dust caps). Tires are 265/35/19 DWS06 all around

Any vibrations with the 5 mm spacers? what brand are they?
