VERSION 2
All of these Zspeedperformance aluminum shields have been road and track tested, Fit perfect and are properly designed. These are laser cut and professionally produced to perfection!
These under shrouds were developed by ZspeedPerfomance to protect your critical engine parts under the car and also because the cheesy plastic OEM shield deteriorates over time and usually ends up on the highway behind you somewhere.
Without the shield in place the air that comes in through your fascia should be directed into you radiator and instead will just take the path of least resistance and exit under the car instead of cooling off your radiator. Just like the upper radiator air guides keep air going thru the radiator, The bottom is even more important to have in place as it is much easier for air to escape there.
The under shrouds will fit all 2003-2008 350Z's with stock front fascias and should fit any fascia that the OEM under shroud still bolts to. These have only been test fitted on stock bumpers.
These will also fit 03-07 G35 coupe/ 2002-2006 Sedans (RWD Only)
Will not fit G35X All wheel drive sedans.
The CuztomPartZ under shroud will help give the lower front fascia much more rigidity also, As you probably know, running without the shield in place at high speeds can do serious damage to the front fascia as it will droop down and can rip apart.
The BEST feature of all thou is that you can actually change your oil AND filter without removing the entire shroud. I have integrated a oil change access door into the shroud so all you have to do is remove 2 bolts and you have ample room to get to the oil filter and drain plug even with the GTSpec V-1 front tie bar in place. Have not test fit with the V2 tiebar but it doesn't look like it will work with it.
Weight on the entire piece is 4.5lbs, The plastic OEM shield for reference weighs in at a bit over 3lbs.
Very lightweight and much more protection!
Mounted, this was one of the last prototypes. The production pieces have 2 bolts on the oil filter door.
As you can see in this picture I wanted to keep as much ground clearance as possible, this will be very close to the level of the front fascia all the way back to the oil pan area. There is a little over 1" of clearance between the oil pan and under shroud so those of you with the 1" oil pan spacers should not have a problem clearing.
This is the finished piece. I have made these in 2 pieces due to the fact that you may crush the front piece on a curb/parking block (it happens to the best of us) it can be replaced without having to buy the entire shield again. The front piece will be available separately in the future.

Fitment
2003-2008 350Z
2003-2007 G35 Coupe
2003-2006 G35 Rear drive sedans.
This will clear the APS aluminum oil pan on the G or Z and also fits with the JWT oil pan spacer and stock pan.
Works with Vortech supercharger kit, Some slight pipe adjustments may be needed.
This has only been test fit with stock front fascias. May require modifications for aftermarket Fascias. If your stock shield bolts on to your fascia this should also as it uses the same attachment points.
