Hi guys,
JMac Racing project update #5 is here!
Suspension and Brakes are finished, installed, and fully tested now.
Tech Specs. on the suspension:
We have three different sets of wheels and tires to choose from on this combo, depending on track conditions, or event rules.
Assembled Front Suspension
Assembled Rear Suspension
Braking is being handled by Brembo on this car.
Using Brembo's new Monoblock GT package, a 355mm x 32mm two piece floating, slotted rotor is fitted to the front. Clamping down on this is a monoblock 6 piston caliper finished in red. The rear uses a 345mm x 28mm two piece floating, slotted rotor. Rear calipers are 4 piston monoblock, again finished in red.
Braking Specs:

Here is what I posted in another thread about this car, and I think the customer chose his brakes:
Hi guys,
Well, I drove the car and I can tell you that after I passed the Galardo and left it behind, I can truly say that this car handles like our World Challenge car but drives like a street car. It is probably about 6-8 seconds faster than a stock z at this small track. it is easily capable of sub 1:19 second laps in good hands.
The car was so good that I am going to do the same mods to my own Z06 as soon as I have time.
The tires that I ran on were the Hoosiers. I am basing all my comments on how the Hoosiers were.
The brake pads were a combination of two brands, Ferodo and Pagid, but that was only because we had to get some Cobalt pads built custom, which we did. And in spite of that, the brakes were flawless with no pedal issues at all.
The Brembo brakes were the customer's brake of choice and it was a good choice. They worked well.
We had our Spindle ducts installed and some custom inlets in the stock location under the splitter/undertray. Again, they worked great.
The custom dry sump tank and pan were also a success, as was our dual oil coolers, which included the stock cooler in series with our LG Super Cool radiator.
We also have a kit for the rear diff cooler on the Z06 also.
At anyrate, from the front to the back, the car was a total success in every respect. Our LG Coil over package with Hypercoil springs did their usual perfect job controlling the suspensiosn and eating the bumps with our Aluminum Bilstein shocks with our World Challenge valving.
And the aero package was dialed in and balanced very well. We left a touch of high speed understeer in it to be on the safe side.
Our LG Drop Spindles as we used in the World Challenge race car not only drop the car without upsetting the suspension geometry also worked as expected. The beauty of the drop spindles is that they not only lower the car and keep the geometry but they add camber and cure the bumpsteer easily as installed.
All in all, the car was a hoot to drive. When I stop racing, i plan on doing plenty of track days with a car like this to get my fix.
Thanks guys,
Lou Gigliotti LGM

I want to know more about those wheelbearings. I imagine my car is about due for some, and if not now, the recent suspension mods will push the old ones over the edge. PM me with pricing, or source, of you are willing to share. Thanks.

Anthony,
Is that bumpsteer kit an LGM product? What's the cost for forum members (please PM me, if it can't be listed here)?
Finally, what's the cost and availability of those wheelbearings?
Thanks!
