Driver's Seat Remount at Home - 2 5/8" Back

Wait at least 90 seconds when disconnecting auxiliary battery before disconnecting leads under the seat, (I think there's a battery backup for seat airbag). I usually take a break to be sure.

Reconnect battery at end of project. When powering up car, press 'power' button once, this will leave dash lights on, press it again and should be good to go.

-----------------------------

Consider whether you'd want to do it to your original seat or a used one.


Feel free to PM me with questions also.

 

thanks dogfriend. so that's what is going on.

and thanks for the link Tom.

 

Follow up. Note - steering tilt not all way down in pics. Reach a little better with tilt full down.

All the way back - equivalent to 4 extra clicks. Reach to dash and steering wheel too far.


1 click forward - Reach a little far to steering wheel.


2 clicks forward - Best balance of legroom, reach to steering wheel and angle for seatback.


4 clicks forward or original position all way back. Eeeek.


Overall greatly improved. As good as the 2010 Prius? No way. I would do this mod again. Totally worth the time and money

 

** Edit - I don't use this cushion anymore and would not recommend it **

Custom seat cushion.

 

3-way attack for more comfort in the seat -

* remounted back for legroom
* Edit - I don't use this anymore >> custom seat cushion for thigh support
* seat cover with bottom cut-off to protect seatback and get bit closer to steering wheel.

Some follow up. Did a coastal mountain pass from Los Gatos to Scotts Valley. Using 3 clicks back from stock max position. The seat position / legroom is remarkably better than stock seat mounting. I've moved seatback 2 clicks forward and reach to steering wheel is really not bad at all.

On the way home, stopped at Toyota, jumped in 2010 for comparison. The new Prius seating is better than mine. The telescopic steering wheel, height adjuster and better positioned brake pedal improve ergos a lot.

In the 2010, it's like I'm more 'in the car or seat' whereas on the 2009 with my mod, I'm a more 'on the seat'.

If I can pick up 24 more HP, I'll be set

 

Yes. The 2010 driver's seat goes about 2 1/2" farther back than a stock Gen2 Prius seat. And, the 2010 seat / steering reach is effectively much better than a remounted Gen2 seat for a very tall person -

* 2010 height adjuster allows more headroom, so can sit low and bring seatback forward for better reach to steering. Plus, you get 1.5" steering wheel telescope in the 2010.

-- Also measured 41" maximum brake to back of seat bottom in 04 - 09 Prius. Little over 43.5" in 2010 with height adjust full down. 2.5" doesn't sound like much, but equates to about 4 extra clicks in a Gen2, something many would like to have.

* In 2010, the gas and brake pedal sure seem to have more even reach to them. IOW, adjust for good reach to gas, move to brake and reach feels the same. Brake pedal is set closer than gas in Gen2.

This seat remount is still a good mod and worth it. Hats off to the 2010 though. It is improved in many ways.

 

How cool, we've got the same results!

**********
I hear ya. No reason to strain for a 2010 which would just set me back. Better to save money.

This is 'splitting hairs', but ...

I used to recline my seatback too much before the modification just to gain some headroom. After the mod, I'm using 3 extra clicks back, so I picked up some headroom since the seat rails have some tilt.

 

3 week follow up -

The front extension braces are holding up fine even though they measure between 5/32 and 3/16" thickness (11/64" , forgot that guage # of steel).

If I had it to do over, I might use 1/4" thick steel for the front braces. If they bent, I'd redo it all over if necessary.

 

About the steering wheel ...

I hold the wheel quite a bit at 6 o'clock, one hand, palm down, but go for another grip depending on traffic.

I'll take the extra legroom with extra reach to the wheel 24/7/365

 

It's looks like the brackets can easily be removed if someone wants to sell or trade-in their car, so that is a good thing.

I can vouch that sliding a Gen2 Prius seat back 3+ clicks extra for a person with long legs is so much better than stock seating. And like you say, plan to move the seatback more upright to keep reach to steering wheel reasonable.

Wish I'd seen your brackets a couple months ago. I looked all over before doing the mod.
