Default Installing DRM front ducts?

Bought some on ebay, but they don't seem to fit. They are too long to just go into the existing sections. Do I have to cut something?

Yep! I just bought some new from DRM and they came with a nice packet of instructions with pictures, I will do my best to write them out as I am scanner-less.

1.) remove wheels, support vehicle securely
2.) remove "close out panels" (Aft of the spoiler on each side)
3.) remove O.E. ducts from vehicle and trim per enclosed illustration.
(note left and right markings on DRM ducts)
4.) Trim inner fender skirt duct hole back towards frame to allow DRM duct to fit through.
5.) Install modified O.E. duct back in place while joining with DRM duct and aligning the final fit. (note any possible interference and adjust accordingly. Fix DRM + O.E. duct with 2 screws to prevent separation.)
6.) Drill small hole into frame corresponding with the outlet hole in duct.
7.) Install screw and washer to secufre the brake duct to the vehicle.
8.) Slip thread duct hose over DRM duct (place ABS wires in center of hose) and secure snug with supplied hose clamp.
9.) Use supplied zip ties to pinch ends to aim toward rotor and avoid any wheel/suspension contact.


As per the cutting.... maybe someone can post up a picture, but the picture I'm looking at for the cutting says to measure 10.5" from the last part of the accordion section and cut there.

Hope this helps!

George, you'll have to trim the inner fender well to get the ducts to fit through properly. Widen the hole inboard, test fit, trim further to fit.
'bout time too; tired of watching you change rotors out at the track..
