First I will start off with this. I go the lower fiberglass filler panel installed. It seemed to have the two rubber pieces beside the radiator, but was missing the lower filler panel. Just want to make sure all cooling aspects are present. installed a clutch Fan with clutch that I searched up on here for the Hayden Part number works better than the flex fan also installed a 160 thermostat. Still running about 210 in stop in go at 90 degree heat. and about 190 at 45 cruising. Have a new 4 Core Champion aluminum radiator on its way hope that helps even more.
So for the lower filler I know a lot of people say the quality isnt the best, but after drilling holes in it to line up with the factory holes, using 1/4 x 20 bolts with "speed nuts" it holds in place very nicely! I went ahead and added a camaro front spoiler for looks as well as the additional downforce you guys say it creates. here are some pics .
Here you can see the Filler panel with the Spoiler. I had to go to the zone for a cheap tap and die kit for the middle spoiler support bar not shown in pic
