Built a splitter with the help of a friend. Current height is 3 1/8" to the ground with approx 0 rake. Tire spats are 1/8" ABS mounted the the bumper and located on the splitter using some U-channel aluminum, An ebay GV lip is attached to the splitter with some self tappers, and the splitter is mounted with quick release brackets, so the entire assembly can come off in about 30 seconds if needed.

I don't care that air dams are objectively better, they are ugly as hell.

Good stuff dude. I really like the look of a big splitter with a GV lip. What size did you go with? Looks to be around a 5” extension?

We just traced the splitter off my friend’s NB champcar, which s a 6” extension from the front of the bumper. Due to the NA underbite, it ends up around 8” forwards from the lip.

More front aero work

First, I built a dedicated duct for my intercooler. The radiator was already ducted, but with the IC just sitting in front of it, I suspected a lot of air was choosing to go through just the radiator instead of the radiator-IC stack. It's 4" long and slightly divergent, hopefully enough to keep a nice pressure gradient across the intercooler core. I debated doing some A-B testing with a manometer or between track sessions, but I convinced myself that it's a good enough design that I just sent it.


Next I blocked off the sides of the mouth that don't feed into the heat exchanges using some ABS plastic. These might come out later if I decide to use that air for other cooling purposes, but for now it's easy drag reduction


don't mind the zip tie splitter rods, I haven't decided what actual hardware I'll go with, so these are temporary(tm)

Got damn that's a big splitter! Looking good with the ducting. Nice build.

Based on Simba’s feedback, I installed a pair of 2.5” risers on the wing. My only concern was improving rear visibility, which is much better now

How did you attach the metal ducting to the intercooler, or is it just resting against it and attached elsewhere?

Curious because I've thought about trying to attach ducting straight to my radiator in the future, but haven't been able to figure out a good way to do it.

kep

My entire duct as attached using the lower two bolts that the AC condenser was mounted on. It doesn't seem like much, but it's very secure with how right fitting it is. The IC specific duct I added recently is just riveted to the main duct at the bottom. I might add a little tape between it and the IC, just to quiet some rattles it makes.

I always keep serviceability in mind, so everything can come apart as easily as possible when needed. So the radiator can still come out without having to remove or disconnect the ducting
