So when you order the Cusco brake cooling baffle plates, you only receive the replacement plates. The stock #25 bolt and Frankenstein washer (not depicted in the previous parts diagram) are reused.

The stock "air intake plate" is a semi-rigid plastic. Left side height measures 5" and right side measures 6". Width is 4" and weight is 56 grams per side. The Cusco carbon composite replacement is rigid and much larger.

FYSA...There is one minor clearance issue that needs to be corrected. After installation of the baffle plate, there is about 1/8" clearance between the plate and bolt head circled in this PIC:

No rubbing between the bolt head and plate for the most part. There is however slight rubbing that you can hear as a clicking type of sound when the steering wheel is clocked full left or full right at low speed. Minor trimming is required in that particular area.

Well, scratch my last post. When the car is lowered back onto the ground, the bottom of the plates touch the top of the end link bolt on each side. The contact point is not under tension. After installing the baffle plates and driving at a low speed, the clicking issue is only experienced when the steering wheel is turned:

• Full left, one click sound on the passenger's side per tire rotation; and
• Full right, one click sound on the driver's side per tire rotation.

Plates are installed on the correct sides (R on passenger's side and L on driver's side). Here is a PIC of the passenger's side where you can see initial contact wear on the plate:

Closer view from a slightly different angle:

Here is a PIC of the driver's side showing initial contact wear only on the lower corner of the plate (so far):

I checked both sides but could not locate where the plates were making contact with another part only once per tire rotation. Any ideas? I plan to just grind the plates a little to eliminate the contact points.

Update...I decided to skip grinding a bit off of the baffle plate where it was making contact. Instead, I took the car to a parking lot with the wheel locked full left and then full right to simply break them in naturally. I still have no idea where the baffle plates were making contact but the clicking sound is now gone.

That's what I would have done!
