Narrowed down my wheel choices
 

Hi all, first of all i would like to say thanks for the responses in my other threads about wheel size decision. Because of that, ive been able to decide on sticking to 17 inches, and around 7-8 width.

My preference looks-wise is between 3 wheels,

TWS T66-F 17x8 - argueably the most exotic and beautiful of them all, with good weight at around 14 lbs only for an 8 width!

BBS RF 507/504 17x7.5/7 - the 7 is 14lbs, and the 7.5 is 14.5 lbs. also a beautiful wheel, looks quite OEM, plus the cool PFS hub rings. I also have the impression that this BBS should be more durable for DD than the TWS.

Oddball: Rota Titan 17x8 17.5 lbs. for the price of one forged wheel, i can get a set of these. I chose against wedsport tc105 because for the price of tc105 id rather add and go forged. With titans, id barely feel the weight savings and theyll probably be more for looks than anything functional.

My question among the three is that how will they impact my DD ride? How durable are they 3 by rank? Any downsides to the TWS vs BBS and vice versa? I have this slight feeling the tws was specifically designed for track whereas the bbs was a dd and track oem wheel

Imho only downside to T66-F - cost. Then again, almost all forged wheels cost fortune. All listed can be used for track & DD. Real "track" wheels .. you meant those TWS wheels that have single center bolt mount for use on some track-only cars? Think of it like that track wheel designing know-how/experience of making wheel strong enough but light as possible just has been applied to these wheels that can be used on street cars :)

Effect of lighter wheels imho is well summarized in eg. this post.
"It appears that lower unsprung mass (like lighter wheels) results in a less bumpy ride over poor roads. However, the downside is that it could increase the "fine vibrations" that you feel over some "relatively smooth surfaces" such as concrete roads or an asphalt road with gravels."
They can provide a bit better acceleration & grip (but possibly not very measurable by easily placebo affected imprecise butt dyno measurements), due less rotational mass for first and due tire staying with road more of time, but that may more show up in slightly better laptimes, not feel.
I had somewhat similar drop in mass (OEM>Taneisya (TWS is "subbrand of them) T6 (one of their old forged wheels) wheels of 6.2kg). Car felt different. Hard to describe in words .. i liked a bit better ride on bad roads, and it felt a bit livelyier/lighter in acceleration .. but then again i'm not very confident how much is what i actually felt and how much came from "expectation of change". Different tires usually change feel much more in handling/grip.

If i had the money to go tws, I'd do it, but since I don't, I got the rotas...they look great, and if one bites the bullet from road hazards, well, you said it, you can buy three or four of them for the price of one tws. Heck, why not get two sets of rotas, one with street tires and one with race tires...maybe even different colors just to have some fun.
