Hi guys
Over the last month or two we've been working to get our drive-train upgrades to the Z34\V36 community along with the 07-08 Z33s.
For those that have never seen or heard about our unique flywheels here's some info.
Our flywheels utilize a patented "segmented" heat shield system. Traditional heat shields warp because of the uneven heat produced by a slipping clutch. Just like a car going around in a circle, the outside tires go faster than the inside tires, the clutch disc slides faster around the outside of the flywheel than it does around the inside. The faster moving outside gets hotter than the inside. Because metal expands more the hotter it gets, the outside of the heat shield expands more than the inside. Traditional heat shields are made of one piece metal rings, so when the outside expands more than the inside, the only thing the shield can do is warp. The segmented heat shields are not connected so they can expand and contract without warping. A warped heat shield causes the clutch to slip, which causes more heat and more warpage.
Example of a warped shield found on other aluminum flywheels.
Our Billet Flywheels are dynamically balanced after CNC machining. Other flywheel manufactures assume that since they CNC their flywheels it comes off the machine fully balanced. This would be true assuming the density of the aluminum is constant throughout the part. Unfortunately even the best billet material is not evenly dense throughout and the starter ring gears are never perfect.
SZ Flywheels are also fully rebuildable for the life of the car. We've been using this flywheel design for over 8 years now with excellent success!
On the Z33 like the Z34 the flywheels used from the factory are a dual mass design. This allowed the flywheel to absorb noise and vibrations. Since aluminum transfers noise easily we focused on designing a performance flywheel that was still quiet while achieving less weight. Less weight off the crank provides freed up power and a quicker, more responsive revving engine.
We provide 5 different clutch options tailored to the car's power and driver's goals. Our entry level Sport Street clutch features a higher clamp load pressure plate able to hold 500 BHP with an organic clutch disc (OE-Style). This is perfect for someone staying NA, or for those making below 450 whp. The Sport 6-Puck we offer uses the same pressure plate but a 6-Puck disc for those looking to drag race. The 6-Puck disc still offers a smooth clutch engagement with the ability to hold a little more power and take abuse.
Our Max Street uses a heavier duty pressure plate to support over 600 BHP that utilizes the same "Street" disc. Followed by the Max 6-Puck.
Our crown jewel is our newly released High 5 clutch. It uses an ultra-light disc to enhance better shifting performance. By doing this one will make it easier for the transmission to get into the next gear. The weight of the disc greatly affects the transmission's ability to do this. Amazingly enough this solid disc provides smooth engagements with barley any chatter. A majority of our customer who choose this clutch daily drive on it. This is the clutch currently on our 370Z TT. This clutch will hold 750whp!
Onto the bearing! The first problem encountered with using an aftermarket clutch is that the OE bearing diameter was no where big enough to properly make contact to the pressure plate's fingers. Secondly a majority of the CSC is plastic which gives way as it ages or sees higher pressure plate clamp loads. Fortunately we also designed our pressure plates to NOT require large amounts pressure to release them which spares the bearing any more strain.
Our bearing upgrades will ONLY work on our clutch\flywheel combos. The bearing we are using required us to change the finger height versus the finger height on a factory assembly. This is the reason it won't work on other aftermarket clutches and would also deter others from copying it. The cost of our upgraded bearing is $160 which would be included in our kit.
As a special introductory offer to the370z.com members we will be offering reduced package pricing.
I want to thank the entire Z community for its support and amazing people over the last 10 years.
Packages include clutch disc, pressure plate, flywheel, bearing, pilot bushing, and clutch alignment tool. Proud to say it's all made in the
