Well i bought my car over a month ago now. I didn't realize at the time it didn't have the spare in it...woops. Oh well. My battery was relocated to the trunk which then caused the thin plywood in the back to bow rather considerably. I then thought...i have to go back to school soon and will have to fully load my car :aigo: . Theres no way to do that if i can't use the trunk, or worry about it breaking all the time. So i thought up a plan and i thought i'd share it in case other people run into a similar problem. Look at the pics before you start so you understand in your head better.

1) I first started with one really long piece of 1X4. I would recomend a 2X4 and find one as straight as possible.

Note: Use a T-square and draw lines for cutting!

2) Next i did some measuring for the proper height. I found just shy of 8.25inches was the sweet spot, this could differ slightly for other people depending if your wood in the trunk is warped/bent. Cut two peices off the 2X4 8.25in in legth.

3) cross supports. 19" in lenght works perfect, you can go about 20" if you'd like. Cut two of these

4) cut two 4" pieces

5) Nail or screw the two 8.25" pieces to the END of one of the 19" piece...NOT under. If you nail under, it will throw off the measurements for height and cause an unleveled surface in your trunk. Be sure to keep the 19" cross support straight as possible and flush as possible with the two other pieces.


6) Now flip your assembled support upside down and place the extra 19" piece perpendicular to the other 19" piece in the middle. Mark 3-4 holes for screws

note: do not use nails for this part

7) predrill the spare 19" piece to a size slightly larger than the screw thread width, and predrill the assembled piece under the screw thread size

8) Screw in the 3-4 screws

9) flip the assembly right side up and place the two 4" pieces at either end of the recently added 19" piece. Make the two 4" pieces flush with the top.

10) nail/screw in the two 4" pieces


And the end result should look something like this:

TOP side

Bottom side

11) now just place this in your trunk and no more bowing or worring about the weight


Note: If you want to prevent possible scratching, use thin felt pads on the bottom of the support structure :icon_bigg

My toyota plywood is very thin and once I took my spare out it would bend easy. A case of bottle water would have it bent really nicely. I just pulled the stupid wood out and use the spare tire space.

Or you could buy a spare at a junk yard for 10-20 bucks :biglaugh:

The idiot that owned the car before me decided to leave a leaky bottle of diff oil in the hatch and it all soaked threw into the pywood, as well as the carpet. Stunk so bad I had to remove the carpet and the plywood :icon_evil


Just in case some people dont know gear oil, it smells like ass...very bad ass...lol

I am going to bulid a new one out of thicker plywood....one of these days

^thought about it but i have too much going on right now to go junkyard hunting. I need to move out in a couple days, i have turbo issues right now, and some family troubles...i needed another solution and i found one...i just thought i'd share the info in case someone else also didn't have a spare and needed some support for that flimsy piece of 'wood'

The stock wood has supports attached to it. Just buy it and be done with it.

The spare is not a big deal to me right now. I'm busy and need to save money right now. I just did this as a temp solution, though it coule be used as permanent. I wrote this up to help if anyone else was in a similar situation with not having a spare...thats all.
