Carbon Fiber wheels

[ayousef]

Just ordered a set of Forgeline Carbon Fiber Viper specific wheels.

they weigh about 16lbs for a 19inch set. A 20x12 that they recently made weighed 18.5lbs and the fronts in 20x10 weighed 16.5 if im not mistaken.

So its safe to say that there will be a 10lbs of unsprung and rotational weight saving PER corner. My bank account is NOT happy though...

Gotta ask, $$$?

[TheStig]

I'd like to see GT350R wheels with viper bolt patterns and sizes. Those wheels look great and are exceptionally light

I spoke to Carbon Revolution they said that they dont make anything for the Viper at the moment, also the wheels are heavier than this if I recall. Those wheels look gorgeous but maybe im biased?

retail is something like $16.5k for the set but thats not what I paid, I got a good offer on them with titanium Tikore wheel lugs and R888R tires.

[PkB2014]

These look awesome. But website shows around $4k per wheel. That's some change right there.

I wouldnt have the guts to pay that much for wheels, then tires, then shipping, and TPMS and additional charge for a custom finish etc... I got a good deal and in all fairness if anyone is interested I can put you through to the guy who gave me the offer. Im obviously not affiliated with the seller and I dont make anything by posting these here, just sharing my excitement lol

The GT350 carbon wheels are heavier than sidewinders if they were our sizes. They are 18 lbs each in puny Mustang sizes

Make sure they fit the right tpms. When I ordered I copied someone else’s design who didn’t care about tpms. Needless to say I had a hot rod shop drill holes in the valve stem to make everything work.

I gave them my VIN so im hoping they source me the correct TPMS thanks for the headsup!

I love your posts Ayousef! You're a lunatic! LOL.
Please weigh them when you get them! I don't think they will be much lighter than Sidewinder 2's, but I hope I'm wrong!
Sidewinder's weigh:
18.42 front
22.91 rear

If you really care about reciprocating/unsprung mass, Pirelli slicks weigh 12 lbs less than Hoosiers EACH, probably 15 lbs less than a street tire

They already weighed the 20's in the picture and the rears were 18.5 and fronts were 16.5. Im hoping the 19's I ordered will be in the 16.5 range all around. There isnt a lighter wheel for our cars period! I looked everywhere.

The only "problem" is the rears only go up to a 12inch wider barrel.

[Racingswh]

All of the possible performance benefit is lost with your tire choice. Like AZ said switch to a slick. More weight savings over just the wheels alone and vastly superior grip.

Curious what the wheels load capacity is like. Is there any fear of them exploding when crashing over curbing? I just don't know anything about them.

A narrower rear wheel will give you less contact patch to the ground tire for tire.
What size front did you go with?

[chris_lee]

Yea... those look incredible! Would take curb fear to level 10.

[serpent]

Did Forgeline already make the wheel? I would opt for 19" rear wheels. I went with a 19front 20rear for my forgelines.
If you are getting carbon wheels for the lightest weight possible you will need smaller diameter wheels.

Not sure about your brake setup but if money is of no issue (carbon rotors) maybe 19" front would be the only choice for wheels to accommodate that larger carbon rotors.

Love that color against the orange. Happen to know the load ratings? I believe the sidewinder2 are around 1400lbs and are soft. Bent my front wheels twice, on slight off track excursions.

Are you sure about the less contact patch? I believe there is way more to it, for example the width contact patch will decrease with tire size width but I believe the contact patch will grow in length offsetting some off the overall contact patch area?

Congrats, although I wish you'd have given a VOA sponsor a chance to take care of you

Forgeline rates these at 1700 pounds loading (I think it was 1700. Maybe Mark told me 1900. I forget which.), vs. 2100 for their racing wheels. These CF wheels are not for Motorsport. The lower load rating and the fact that the barrel is clearcoated carbon fiber means they won't react too well to hot brakes. Word is that they will discolor. I'll keep them on the street only.

When I ordered mine, they only offered 20s and 21s, so the Orange is on 20x10 fronts and 20x12s in the back. Tire contact patch with a 345/25 20 Nitto Invo is about 25mm less than a 355/35 19 Corsa. Pretty much exactly as expected. A 305/25 fit on front just fine. I'm stuck in Tire Hell with this combo. There aren't too many choices. Front and rear wheels weigh the same. Forgeline said the extra aluminium in the hub makes up the weight difference in the barrel width. Obvs, these are a two-piece wheel. The barrels are made by Emergent Carbon in Kansas City. http://emergentcarbon.com/. Forgeline machines the centers and does final assembly.

The center finish on the TA is Transparent Smoke. I just couldn't bring myself to do something crazy like transparent candy purple or blue. Oh well.

Overall weight is about six pounds lighter each. I wasn't able to weigh the wheels alone, as I had Forgeline install the tires. Ain't nobody around where I live going to touch CF rims. Special machines only.

And yeah. Do. Not. Curb. These.

There's also not much tire when you're running 25-series all around, so don't go pothole hunting. I'm told these bend and spring back when they hit something, but I'm still careful AF. I don't want to chance it. (Not that I don't care about other wheels, of course)

I'll post some pics in a bit. Typing on my phone currently.

[nitromilt]

Oh lord..... I thought spending 2500 a wheel foR ADV1 3 piece wheels to put on my Panamara Turbo was crazy

[13COBRA]

To spend that much money on a lighter wheel to never see the track is absurd, but to each their own.

[ViperGeorge]

That's a lot of moola.

[PittsburghRT]

Beautiful wheels, but rears need a bigger lip. Just does not look right to me.

Here's the center during production (pic from Forgeline):

A mounted rear (also pic from Forgeline):

And another mounted shot. Stock ride height, ACR-E diffuser. (pic taken by me).

In theory, a 305/25-20 is 26mm taller overall than a stock 295/30-18 and a 345/25-20 is 15mm shorter than a stock 355/30-19, but I've not measured actual height differences. The only set of Corsas I have lying around are pretty worn down while the Nittos are new. I took an educated guess at the tire size and either I know what I'm doing, or I lucked out.

There's no rubbing in the front at full lock, and a new set of OEM TPMS sensors fit the wheels just fine, and relearned themselves to the car after ten minutes of driving. No problems at all, and the pressures read correctly.

To note, the TPMS sensors clamp onto the carbon barrel, not the center section (duh), and the barrels are "universal", so no special work needed done to accommodate the sensor. Just to cover you though, make sure to specify that when ordering.

As to answer 13Cobra's comment on the absurdity of spending this kind of money on something that you can't track.... what's more absurd:

1) Spending six figures on a car that will never see the street and never not be wearing Hoosiers and get a new set of brake pads with each oil change,
2) Spending six figures on a 9.0-liter heads & cam ACR-E that sits in the garage that you drive one time a year, or
3) Spending six figures on a car that has been driven 37,000 miles in the rain, snow, and on dirt, all over the country, into Canada, and on the racetrack, and then deciding to spend five more figures to buy something awesome that will work perfectly in 99.98% of the environments the car will see?
