splitter mounting
Hi folks, I'm building my first splitter from alumalite and looking for some wisdom. I cut the first one for 6" extension. Too far? I have a 1700mm chassis mount APR-250 with gurney flap so I'm anticipating no shortage of rear downforce to balance out. I have the DevSport frame-mount brackets for main support, but I'm wondering where else people commonly attach their splitters.
Should I bolt the splitter to the stock bumper bolt locations (3 on each leading edge of the bumper)? I'll be using angle-stock for a small dam to allow flat splitter angle of attack, but I could use spacers or washers to still attach the splitter to the bumper, too.
I built the splitter to extend pretty far back, so should I look into bolting it to the subframe somewhere around the front jack point?
Any need for turnbuckles on a 6" splitter? If so, front, or side edges, or both? Ok to mount them hidden inside the bumper, or does that take away too much leverage?
When people are doing splitters, are they commonly cutting all or part of the plastic flat undertrays that extend forward from the fender liners on each side? I think I can leave most of them if I cut space for the DevSport brackets, and they provide the captive nuts for the bumper bolt holes.
All thoughts welcome.

the two radiator supports are using spare endlink bolts so they are like 3/8" thick using old camber cam plates as washers (i never throw parts out so i use stuff randomly)
turnbuckles are mounted to plastic with 2" washers behind them, it will definitely deflect the bumper a few mm when you stand on the splitter but i just consider that "active aero" lol
if i could find longer turnbuckles i would have mounted to the metal behind the bumper

Just for comparison the Wasp splitter mounts with 3 bolts (and washers/nuts) to the radiator support, as well as the brackets that attach to the frame with another 4 bolts (two per side)

Also made an Alumalite splitter but 5 inch extension. I too used the dev sport brackets as a starting point, and then added 2 more mounts on the outer edge of the splitter, in front of the fender liner, and finished it off by adding 2 support rods which I mounted directly to the front bumper beam. Its rock solid now, and as per the typical splitter test, I can indeed stand on it and I weigh about 180.

Make ur splitter longer and wider than needed. U can trim it on the car. U can mount easily to the frame and then use rods to support the end. I'm making mine this weekend.
