Topic: Custom Molded Seat Inserts
We recently put a new Kirkey containment seat in the Dart for a little added protection, and we went with the biggest we could find (18.5" wide) to accommodate a 300+ lb. driver. My comparatively skinny 6'4" 215 lb. frame is sliding around in the seat, and trying to keep myself upright in the corners ain't doing my lower back any favors. I'm looking at these custom seat insert kits and would love some opinions from anyone who might've used them. The intent would be to make one for every driver that needs it and swap them during driver changes.
Is it feasible to mold one of these over the standard seat cover, so it can be left in place when the custom cushions are swapped out? How do the custom cushions hold up if you install and remove them a couple times every race?
1. $345 Pegasus Creafoam kit (for the size I'd probably need). Would need to buy the fabric cover material (~$100), doesn't include the knife or required vacuum pump (maybe I could make an A/C vacuum pump work?). Looks like a more complicated process. Instructional video isn't great, but Pegasus is apparently pretty responsive to questions.

2. $254 Kirkey kit. Includes everything you need including electric knife to trim the edges, uses solid foam sheet for butt padding. Not entirely sure it'll be big enough for the side bolsters and lumber support I need, but it looks like I could buy more of the foam sheet ($45) and add it to areas that need it before pouring the mix. Great instructional video.
3. Cheap Lemony solution with garbage bags and two-part foam that won't melt to my skin in a fire? Anyone done this successfully?
