2007-2008 350Z Radiator Cooling Panels Now Available!

17 Apr

This is our latest product – the aluminum cooling panel (aka radiator shroud) for the 2007-2008 350Z’s. These are all made here in the US of T6061 aluminum, and powdercoated locally as well to ensure the finish stays, and lasts. Since the radiator core supports are different between the 2003-2006 and 2007-2008 cars, we had to create a new part that would fit properly. Many manufacturers out there have inaccurately said theirs fit all year cars, and it’s simply not the case. While the HR was only around for 2 model years, and is not as popular as the previous DE engines, we felt it deserved some of it’s own attention.

Some highlights of this product:

– Installation literally takes a few minutes. Simply use a small flat head screwdriver to remove the clips are the front of the bumper, slip the cooling panel in place, and reattach the clips. Nothing needs to be trimmed, cut, modified, or altered in any way.

– Will work with any intake, stock or aftermarket.

– Fully powdercoated on both sides to ensure a durable, brilliant finish

– Funtion or form? A little of both, but it’s mainly form. The theory behind the function side is that by covering the open area between the radiator core and the bumper, you are forcing more air through the radiator. This is true to an extent, but the primary function of this piece is to tidy up the engine bay, and help disguise the bulky hood release area.

We have 30 pieces in stock now, and will be ready to ship next week (they are all being coated as we speak).

Pricing for the initial batch (your choice of flat black, or gloss silver) will be $129 shipped in the 48 states. For anyone located outside of the 48 states, simply contact us with your complete shipping address (not just a postal code, or country please!) to z1sales@z1auto.com, or via PM and we can let you know the cost.

New ATS Clutches for 2007 + 350Z and 2009 +370Z/G37

28 May

When Nissan implemented the VQ35HR engine on the 350Z, they did away with the older slave cylinder setup, and employed a CSC (concentrical slave cylinder) inside the bellhousing. As many have found out, this piece has proven problematic, and prone to breaking. That means dropping the transmission, replacing it with a new one (hundreds of dollars each time) and keeping your fingers crossed. With an aftermarket clutch, the problem only seems to be maginified.

ATS has come up with their multi disk clutch setups that completely does away with the CSC! These are offered in several configurations, ranging from a twin metal disk version that reuses the stock dual mass flywheel, to a triple disk carbon that includes an integrated lightweight flywheel.

These come with your choice of an 1100 kg pressure plate, or 1350 kg pressure plate depending upon your torque requirements. A reinforced NISMO slave cylinder is also offered as an option.
