Our 355 challenge wheels

Nice looking wheels
Are they exact looking from the outside

 

Compare the differences?

And are they available with the regular Speedline typeface instead of the Corse script version?

 

I think he went through this a while ago.

What were the offsets again??

 

if these were made in 19" I bet they would sell like hot cakes.! despite the performance advantages of the original challenge wheels.. I simply could never appreciate the look of them on the car, where imo the oem wheels look much better/correct. the only time that I see the challenge wheels look correct is on an actual challenge car. but on a normal road going 355 where many owners leave their cars stock ride height with the big floating wheel gap up front.. the challenge wheels just don't work aesthetically.

but.! these made in 19" would be a different story..

 

One of the advantages of the Challenge wheels is their lightness. I had a set of HRE 3 piece wheels and they were heavy. You can definitely feel light wheels when driving and the ride and handling is different. These wheels look great but I bet they are on the heavy side.

 

I would never put 19" wheels on a 348. 18" all the way.

 

maybe for the 348. since oem is 17”

but the 355 with oem 18s can easily handle a 19 wheel.

 

Both are the same cars basically, so either can “handle” a 19”, but I think at that point the wheels look too big for the size of the car. No thanks. 18” all the way.

 

Nice looking wheels.

 

I am not sure how fast you drive on the street but based on my tracking experience I am not sure I would ever be able to notice this on the street.
Track is a different story, but we should all remember that many people are putting 295 tires on the stock or challenge wheels which are not very light. In some cases this xtra weight of the tire will exceed the lightness offered by the magnesium wheels thus offsetting the real,benefit over a smaller lighter set of rubber.
Just pointing out some facts I have seen on here over the years.

 

You will notice it on
the street if you have 18 lb wheel vs a 23-24lb wheel. Yes tire weight makes a difference. My HRE wheels were 3 piece and heavy because of all,the bolt hardware. You could feel the difference over rough roads and turning. Ask the guys with GT350r with carbon fiber wheels vs a regular GT350 . They will tell you they can feel a difference.

 

As mentioned above a 19" version would be really cool.

 

You, or the end user could always hog out some pockets from the back of the spokes and lighten them up quite a bit without sacrificing strength. They can also be balanced via this method. You would end up with a superior product to the OEM wheels.
Yuuup 19s with hogged out pockets is pure seex

 

Not sure who told you about Magnesium shelf life but if looked after properly my experience has shown no issues.
My only bad experience with magnesium wheels is they are generally made quite light and they do not like pot holes.

 

Pricing??

 

The standard wheels are magnesium too so would these be heavier than them?

And, as above, what is the pricing? They do look very nice.

 

I inderstand that just wanted to share some facts. The original pirelli were under 23 lbs and many very popular tires guys are running in the 285 range are of the order of 27 pounds.
So even a 4 pound heavier tire on the magnesium rim will be the same as a pirelli on the 4 pound heavier rim thats all.

I am all for the lighter is way better crowd but some are not all was comparing the same thing.

 

Tires can be lightened by having half of the tread shaved off. That used to be popular before the tire manufacturers started making treaded tires dedicated for the track. The tire will also feel more responsive because the rubber isn't as thick and won't squirm around as much. And since most people replace their tires due to age, not wear, you're not really losing anything.

But don't think just about static weight. Larger outside diameter tires and especially larger diameter wheels move the mass (even if it's the same total mass) further out from the center of rotation which can greatly increase the angular momentum of the wheel and tire.

 

Close, but not close enough. Nothing beats the original.
