I understand that HREs are a gold standard when it comes to wheels... however, based on the looks and fact that both Titan 7 and HRE P101 are true forged wheels, is there a reason to pay more than triple? M5 sizing in 20" Titan 7s are $3k for a set and HREs are $10k...
Thank you

So I am in the same boat, regarding titan wheels. Some photos I see them look larger than one another and fitment is different. I guess suspension and tire could play a role, but look at the differences between the two below.

I would rather spend the $3k than more when these are forged too.

Just got me scared when the below pics are the same wheel and look completely different.

The F90 top pic (Donnie grey) is my vehicle - I realized after I posted that the angle of the pic alters perspective more than in real life. The suspension is entirely stock, no drop, with no spacers. It looks quite balanced. Handles great. Price point and quality are solid.

Are you still on stock suspension? Or do you plan to lower it?

Happy as is, not planning on lowering or changing suspension at this time. The wheel gaps on the Titan a bit less than with the 20” oem wheels. If significantly reducing the wheel well gap is your thing then lowering / spring change would be a solution. This is my daily and I don’t want to be any lower than I am.

I’ll try and take a proper perspective pic (not angled) for you.

Thank u for responding... I started digging more and it seems that Titan wheels are flow forged and not full forged... considering the condition of Midwest roads, I may go with full forged setup. If I am wrong with my assessment of full vs flow forged...please let me know.

Titan’s are fully forged.

Here all, these pics are more representative - forgive my photog skill or lack there of. This is what they really look like on a stock 2019F90 in the wild: not recently washed, not professionally photographed, not staged. First 2 photos at waist height. Other 2 photos at head height.

The Titan7 20” 5 bolt spec for F90 have a single front and single rear (front vs rear are different) offset and dimensions, so not customizable as far as I know. My opinion - differences in appearance come down to base vs comp (comp 7mm lower), any aftermarket suspension drop and/or spacers. Also, I went 285/35 front and 295/35 rear, some have gone 305/35 rear.

Finally, important factors such as a darker car / lighting, black vs titanium wheel colour, all these are all going to contribute to give an optical illusion as to relative wheel well gap and size in relation to the vehicle. It’s hard picking new shoes isn’t it? First world problem for sure, don’t worry, you’ll do fine; a few years from now something else will catch your fancy. I think we all are afflicted with a curse. Good luck!

Ps: Titan7 are fully forged.

Those wheels look fantastic. What's the weight of these wheels?

Comparison per recall and quick search as follows:
Titan7 T-S5 forged 20”:
Front 10” @ 10.3 kg, rear 11” @ 10.8 kg

BMW 706M light alloy 20” (black and bicolour)
Front 9.5” @ 16.0 kg, rear 10.5” @ 16.5 kg

BMW 789M 20” comp forged wheel
Front 9.5” @ 12.7 kg, rear 10.5” @ 13.4 kg

So approx combined wheelx4 mass (minus rubber) is:
706M = 65 kg
789M = 52 kg (13kg less)
T-S5 = 42 kg (23kg less than 706 / 10kg less than 789)

Fairly significant considering it is sprung / rotating mass.
In real world, to be accurate, must allow an extra pound per tire for the T-S5 given they will be fitted with one width increment wider rubber.
Overall, benefit on acceleration and handling should be greater than even the option of the 19.4 kg weight saving advertised for the carbon ceramic brake option(not cheap). The Ceramic brake weight saving is closer to the rotational axis and thus not as beneficial with respect to rotational momentum - here significant advantage goes to the reduced mass of wheel barrel farther out (moment of interia more impacted).
Now, that said, both TS-5 and ceramic would be great. Next take out seats lol. The rabbit hole of trying to make a two ton car lighter.

Thanks - very helpful! The T-S5s are really light. It is fun to think about both the physics of sprung mass and (more importantly) lightening this mass.

Wow good info! I am glad that i did go for the 789M wheels on my comp thats a big differens in weight compared to the 706M!
I expected the 789M to be lighter but not that much lighter.

I do think the 789M is much better looking wheel anyway.
And i also looked up the price on the stock wheels and the 789M is alot more expensive if you want to buy them afterwards.

Of course if you want to shave some more rotating mass off the car (and shave alot of money from your bank account too LOL!) you can go for a good set of aftermarket wheels.
