Add tilt adjustment to passenger seat?

[soupcxan]

I bought a 2011 HL V6 SE because I didn't want most of the upgrades that came with the Limited, but a few months in the only thing I wish I had was the ability to tilt the front of the passenger seat up a little. Does anyone know if there is a way to make a permanent adjustment to raise the front portion of the seat (maybe install some spacers on the front bolts where the seat attaches to the body)? Or are there any options (OEM or aftermarket) to add power tilt to the passenger seat? I don't mind spending some $ but I'd rather not install aftermarket seats (want to keep the OEM look).

You can put washers under the front seat bolts. I've done that on a different car but can't attest to how safe it is or isn't in a crash. I probably wouldn't do this one again.

On another car the metal seat pan was held on with 4 bolts and I took the seat apart and reshaped the pan at the rear bolts to sit lower. More work but possibly safer, though I don't know if the HL seats are built this way.
