BST Carbon or Marchesini Forged??

Curious as to which you guys would prefer. Looks like the BST wheels are lighter but I'm a bit concerned about durability. Would the Marchesini Forged Aluminum be just as good?

I prefer the Marchesini, they look better imo
and I won't care for the little extra grams in weight savings the BST give. For both street and racing

I will get a set just to have a second set off rims. Not every track day is sunny.
My picked would be forge aluminum. Do to cost.
I can't justify $4k for wheels and rotors.

Go marchesini, I had set of BST on my mv. Loved them and they made a huge difference but at a track day the tyre guy cracked the rear rim when he was changing it. So since that ill stick with marchesini

Exact same question ditto in my head
PVM seems to make good forged alums too - which happen to be the same thats featured on the HP2. Lesser weight than Marchesinis even. Available through Alpha Racing. Wonder who makes/what are the specs on the HP4 wheels. Expect some to be on sale(HP4 ones), when ppl swap out the stock HP4 wheels for BST's.

PVM or Marchesinis - PVM's look horrible compared to Marchs but lighter, besides they are available in that cobalt blue, same color as the HP$ wheels.

Let me know what you decide.

If I would do mostly road-track I would go for CF BST.Now for the track in my opinion the magnesium is the way to go Marchesini or PVM.With aluminum you will notice some difference but it does not compare with magnesium and CF.
A friend of mine has the PVM aluminum and then bought magnesium and there was really big difference.

Just a word of caution on carbon fibre. It's fine for stuff like body panels but on stressed components like wheels it does age and weaken. I looked at CF in aerospace design some years ago to strengthen some mechanical components but under examination it gradually develops micro cracking and softens in stressed applications.

Racers using carbon wheels don't keep them forever. So I'd always go for forged metal if you're expecting 10 years + life from them.

I believe this statement is true also for magnesium wheels because magnesium, after a lot of stress and time, can develop internal cracks.They check the magnesium wheels with X-Ray after some time (do not know exactly the time interval).I saw that Marchesini has some magnesium wheels for Road and some for Race.Maybe they reinforce more the Road magnesium wheels...

Really depends on your intent.

If you're looking for something that has a bling factor, then go w/whichever provides that for your own liking. If you're doing it for track purposes to improve your lap times (tip in, acceleration)... IMO, you are MUCH BETTER off spending the money on good ole fashion seat time (trackdays, private track rental, etc.).
