I'm dating myself by calling the Mugen Sport Suspension a "lowdown" kit. I guess this is carryover from the days when Mugen was marketing there non-adjustable spring/shock assembly as the Lowdown Kit for EK9 and DC2.

Anyhow, I wanted to post some technical information I've researched on the two version of the kit for 2nd gen TSX. Physically, they appear the same, but there are some differences. Both will lower there respective vehicles 20 mm all around.

For the sedan (I4), the part number is 50000-XLL-K0S0

For the sport wagon, the part number is 50000-XLLB-K0S0

The front assemblies are the same for both kits.
The rear is what is different, looks like only the spring rate is different. Sedan has 32 N/mm (3.26kg/mm, 183 lb/in) VS the Wagons 35 N/mm (3.57kg/mm, 200 lb/in). Dampers are the same.

Makes sense to me, there is more weight over the rear of the wagon.

Are the kits interchangeable? Yes, but the lowering amount will vary at the rear.
By how much? I haven't figured that out yet.

Pictures of said Sport Suspension on wagon? Google search! but to help you get started, not my car...

That being said, order the correct kit for your vehicle, or go with an adjustable coilover suspension where you can change the height or rear springs for the wagon (likewise for the fronts of V6)

Interesting. The biggest takeaway I'm getting is that the Mugen spring rate is ~9.5% greater for the wagon vs. sedan. Which is a good bogey to keep in mind if trying to adapt a sedan set to the wagon (or vice-versa, I suppose).

Good info!
