Improved Cooling.
A new oil cooler cut out is designed rubber to seal onto the OEM cooling shroud, helping heat dissipation away from the oil cooler.
Made from 5251 Aluminum.
The gauge used creates a 2mm thickness to achieve a balance between protection, and weight (3.6 kg).
Brackets, bolts, nuts and washers are included.
All of it.
Adjustable and pre-threaded holes.
The undertray was designed with slotted sections to allow adjustment along with threaded inserts.

Build Journal: product series
E46s don't crack*.
I cracked and replaced my E92 M3's undertray twice before calling it quits and fitting the Lightweight Aluminum Skidplate.
My E46 M3 experience was a tad different.
The previous owner simply didn't bother replacing the OE plastic undertray sections: they weren't even there.
In this Product Series, I'll be doing it once and I'll be doing it right by documenting and fitting the Performance Aluminum Undertray.
Cheers,
- Matt
