99-04 Mustang Race Seat Base & Mounting Bracket Options?

This year I'm planning on switching from Corbeau FX1 Pro seats with the Corbeau 99-04 Mustang specific base mounts & sliders to a fixed mount, halo seat to also be used with a HNR system. I'm concerned about overall seating height. For reference, the Corbeau seats with the mounts and slider brackets put me approximately at the same seating height as the stock seats IIRC. That would be ok, but I certainly wouldn't want to go any higher. I have a convertible with a 4pt rollbar and I'm 5' 11" and just barely pass the "broomstick" test.

With that in mind, my thought is a 99-04 Mustang specific base (like the one's made by Planted Technology), plus seat mfr-specific side mount brackets at the lowest setting should not raise the overall seating height more than stock, but I suppose it all depends on the seat mfr. and/or bottom seat padding thickness.

Seats I've tried out and like are the OMP HTE-R and a Cobra Evolution Pro Fit, but I'm also considering a Sparco Circuit, Sparco Pro ADV or possibly a GP Race.

Does anyone have any first hand experience with fixed mount bases used with side brackets and what that did to their seating height? Did you have to go the custom mount/bracket route or make modifications?

I made a custom base for my race car out of 1" square tubing. You could do the same just takes a tape measure, chop saw and a welder. I then bolted aluminum plates on the outside of the seat bracket and then fitted the seat. Drilled holes through the side of the seat and put bolts through.

I was going for low profile with my seat mount, the dyno guy that first tuned it could barely see over the dash.

Seat is an aluminum kirkey rr seat.

Looking for a low profile base for my 2003 Mach1 with Sparco evo 3 seat. Any new bases out there?

Wedge engineering.
Also the bracket for the 1994-1998 is a bit lower, but you need to drill a bolt hole to mount the seat belt to the transmission tunnel.

Thanks for the info. So it's pretty much coming down to Wedge and Planted Technology base bracket. Anybody know which one is more low profile? Sliders would be nice but I'm thinking I'll have to do a fixed set up to stay low as possible.
