SRT-10 & SRT Coupes lose over 100lbs rotating weight from your wheels/tires/rotors

SVS has put together a package where owners of SRT-10's or SRT Coupes would be able to lose over 100 lbs of rotating weight from changing out the stock wheels, tires, and rotors for street driving.

For those of you that don't want to change anything in your engine bay then this is the ultimate package for adding value and higher performance to your Viper.

The wheels are an exact replacement in size and offsets (19x13 & 18x10) in comparison to the stock wheels on both models. They’re the highest quality 1 piece forged magnesium wheels available in the world! There are no compromises in the building of these wheels for integrity, strength and style for the street or track.

Stock Wheels vs. SVS 1 piece (5 spoke) forged magnesium

SRT-10, SRT Coupe stock wheels/tires Michelin Pilot Sport run flat:

Front 18x10 = 60 lbs. ea.

Rear 19x13 = 73 lbs. ea.

SVS 1 piece forged magnesium 5 spoke wheels and same Michelin Pilot Sport:

Front 18x10 = 45 lbs. ea

Rear 19x13 = 55 lbs. ea.

Weight loss by changing wheels and using same tires = 66 lbs (+/- 2 lbs)

Stock front and rear: 266 lbs.

SVS front and rear: 200 lbs.

By changing to a new set of Michelin Pilot Sport NON run flat (zero pressure) tires you’ll lose another 3 lbs per tire:

Weight loss by changing to a zero pressure Michelin Pilot Sport = 12 lbs (+/- 2 lbs)

By changing out the stock rotors and replacing with Brembo 2 piece race rotors you’ll lose another 10 lbs. off each wheel.

Weight loss by removing stock rotors and adding Brembo race rotors = 40lbs

Total rotating weight loss wheels, tires and rotors = 114 lbs.

When adding the SVS rotating weight loss package to your Viper you’ll notice that acceleration and deceleration and handling will be greatly improved. When losing over 100 lbs. of rotating weight your drive train will experience less stress under load. Rotating weight loss equals a significant amount of static weight loss and can have a substantial increase in performance.

This is the ultimate weight loss package for your SRT or SRT Coupe.

1 piece forged (5 spoke) magnesium wheels (18x10 & 19x13) $ 10,300

Michelin Pilot Sport Zero pressure tires (same sizes as stock) $ 1,600

Brembo 2 piece race rotors $ 2,500

$ 14,400

The manufacturer builds wheels for F-1, exotics and are the OEM supplier of wheels for Chrysler products. They're available in different colors.

Ron, you are telling me that the fronts weigh 22.5 lbs. each and the rears weigh 27.5 lbs each WITH a mounted runflat?

That's hard to believe. I think 18" SSRs WITHOUT tires weigh in the 22 lb. range.

What are the unmounted weights? Also, you show a picture of a hub drive wheel---I'm assuming this isn't a conversion but is drilled for stock pattern, correct?

Very impressive.

wow - getting 100lb off unsprung weight has got to be good! That's an amazing saving.

Are the wheels available in a polished/chrome like look?

Nothing looks quite as good as polished magnesium, but I am unaware of any coatings available to keep it looking good and it is much more labor intensive than polished aluminum.

73lbs for each rear wheel, holy piss, did they cast it out of lead

I'm curious as well, are you guys converting vipers to a hub drive? do it

Those wheels do look sweet, but if your going to drop a ton of rotating weight why not go with really light wheels? There are a couple street wheels in the sub 20# range. (not sure if they have 19's yet though)

Holy shit those are some expensive wheels. I think I'd rather have a Paxton. I'm sure I"d notice the difference in power too.

That's why I mentioned I thought it would be a good way for owners who don't want to modify their engines........

For those who want the Paxton and the lighest possible wheels/tires/rotors than this is how to get it!

Very Sharp Ron. You should look into making these for the SRT Ram. The stock wheels are MAD heavy...

If someone wanted the wheels with a center lock design we can build them that way. These will come with the Viper 6 lug pattern.

I just got off the phone with Michelin......

When I calculated the weights in my first post above I figured the tires from the TireRacks website and the 36lb 345/30/ZR19 on their site is what the NON RUN FLAT weighs. I thought the 36lbs was the RUN FLAT.

The RUN FLAT tire weighs 38.81lbs, what a heavy tire!

If you just changed out the stock wheels to the mags and used the same run flats that come on your Viper you would save 52lbs.

SVS Mag Rear 19x13 20lbs
SVS Mag front 18x10 17lbs

I understand the wheels are expensive but they're the lightest and strongest wheel you'll find.

I recalculated and the corrected figures are below:

Stock Wheels vs. SVS 1 piece (5 spoke) forged magnesium

SRT-10, SRT Coupe stock wheels/tires Michelin Pilot Sport run flat:

Front 18x10 = 60 lbs. ea.

Rear 19x13 = 73 lbs. ea.

SVS 1 piece forged magnesium 5 spoke wheels and same Michelin Pilot Sport run flat:

Front 18x10 = 48 lbs. ea

Rear 19x13 = 59 lbs. ea.

Weight loss by changing wheels and using same run flat tires = 52 lbs

Stock all wheels/tires front and rear: 266 lbs.

SVS Mag wheels stock tires front and rear: 214 lbs.

By changing to a new set of Michelin Pilot Sport NON run flat tires you’ll lose another 3 lbs per tire:

Weight loss by changing to a zero pressure Michelin Pilot Sport = 12 lbs

By changing out the stock rotors and replacing with Brembo 2 piece race rotors you’ll lose another 10 lbs. off each wheel.

Weight loss by removing stock rotors and adding Brembo race rotors = 40lbs

Total rotating weight loss wheels, tires and rotors = 104 lbs.

Thanks TC

NEEZ is the brand name.

The largest they make in a Magnesium wheel is 19X13

Are the rear wheels 22's on the SRT Ram?

Here's more info and pictures.

When the hyper silver arrives I'll have pictures on a Viper
