Project Viper: Part 16 – Forgeline VX1-6 Wheels and Michelin Super Sport Tires

Fresh performance tires are crucial for keeping Vipers safe and predictable.  We upgrade our Viper with Forgeline’s Monoblock VX1-6 wheels wrapped in new Michelin Pilot Super Sport tires.

As we demonstrated in Part 3 – Baseline Track Testing, the Viper is actually quite tame and predictable to drive on new tires.  In fact, it behaves a lot like a big Miata or S2000 but with torque and no ABS.  Our Viper came with a set of three-piece Forgeline GA3R-6 motorsports wheel and a set of Gen-3 Viper-spec (C1) Michelin Pilot Sport PS2 tires.  These are lightyears better than the original 17-inch wheels and ancient tires that the car originally had, but they were overdue for a replacement.

Forgeline VX1-6 Viper WheelProject Viper GTS was the first car to receive Forgeline’s forged monoblock VX1-6 wheel, which was adapted from the 5-lug VX1.

Forgeline VX1-6 Viper wheelThe Forgeline VX1-6 wheel is a fully-forged one-piece monoblock wheel that utilizes computer-simulated FEA design and manufacturing technology similar to their GA1R and GS1R racing wheels.  This ensures a wheel that is lightweight, exceptionally strong, and stiff.

Billy Johnson Chris Hoy Multimatic Donnington Park GT4 Win British GTI’ve been a fan of Forgeline for many years now, and have won many professional races with their wheels.  What makes Forgeline credible to me personally is not just that they actively supply wheels to professional race teams worldwide, which is the best proving grounds for pushing designs to the limit, but they understand and market the importance of wheel stiffness.

As I talked about in the article Does Wheel Stiffness Affect Performance? -wheels can be made too light, flimsy, and greatly hurt the performance of a car because of it.  Unfortunately, some big-name companies chase the easy sale of designing the lightest wheel possible, at the cost of performance and durability.  Forgeline uses their motorsport experience to make the best performing wheel possible that will help you win a race, which will never be the lightest wheel design.  Knowing where to strengthen and stiffen a wheel to improve performance is where their motorsport experience comes in.

  1. gorgeous wheels and tires. not sure if i missed it being mentioned in the article, but why didn’t you go with the PS4? I love the michelin feel when they are new, but they age and crack SO fast, even in a garaged car in Los Angeles. They dry rot and plasticize within 5 years easily. I know its recommended to get new tires every 6 years or whatever, but its a bit dramatic with Michelin from the sets I’ve interacted with.

    1. The PS4S was not available in the Viper size at the time of the install. The previous “C1” Viper compound was well over 5 years old and did not have dry rot issues, neither have a lot of the PS2 or PSS tires that i’ve personally used.

    1. It’s not always the wear but the age of the tire that matters. The tires were old and needed replacing; plus the tread was down to the wear marks and the outer shoulders were worn completely; close to cords, and would not last much longer on track.
