But nobody is mentioning the significance of dumping the OEM heavy run flats which adds 4 to 7 lb per tire, per wheel of unsprung weight. Add Run Flat Delete to one piece aluminum monoblocks and add aluminum two-piece rotors, that's significant on unsprung weight savings. 75-80lbs unsprung weight.
Love a set of 7075 forged aluminum lug nuts as well, smokes heavy steel.
If I were tracking the car I would ditch the run flats on the track wheels. But, for a street car that my wife drives, there is no way I am getting rid of the run flat tires.
For the track, I would run titanium lug nuts. I would never run aluminum lug nuts on the track. On the street the weight savings doesn't really matter. If I were concerned about the weight of the steel lug nuts on the street, I would use titanium lug nuts there as well. So mo aluminum lug nuts for me...anywhere.

Run flats weight savings is just for me, can't for the life of me get my wife to drive my C8. I hear you on titanium lug nuts but it is known 7075 tempered aluminum do show a higher hardness than titanium. Splitting hairs and who cares.

+1 on 7075 Aluminum. As an added bonus, it's also still softer than the SS lugs, so if you cross-tread or overtorque them by mistake, the lug nut loses the battle before lugs! I change tires a thousand times (exaggeration) every track season, but never had to replace a lug.

I ordered two complete sets of rims. One Apex set for track duty….in smaller diameter. Then a
different brand for street set in larger diameter. The Apex by far are the lightest and I’m confident they are the best made rims available.
Track ready Track set mounted. Street set dismounted. Apex close up with gorodisc rotors Apex view Quality Quality
