For a little history, when we first built the Prelude for Lemons we gutted most everything we could, and got rid of a few things we should not have in the process. One was the heater core (who knew it might rain and we’d need a defroster?) and another was the rear glass to keep the exhaust fumes out.

We initially had a side-exit exhaust so the fumes weren’t much of an issue. After a few races we decided the loud-@ss exhaust was just too much, so to have room for a real muffler we had to route the piping in the stock location. Once we reworked the exhaust, the fumes indeed became an issue, so we decided to do something about it before the 2013 season.

We have been wanting to shed some weight for a while (did I mention I’ve lost 25 lbs since last October?) and improve our aerodynamics along the way. Ryan sent the team a pic of a mod Bowie Jr. did to their Civic and that got the ball rolling to proceed with what we now call the “Fastback Edition” Prelude.

Ryan sourced the parts and construction details and then we got to work. First up we removed the trunk lid and did a little planning with tape to get the concept:

Image



Next, I let Ryan loose with my air hammer to do what he does best…demolition!

Image

Image

Image

Image

Image



Demolition complete:

It just so happens that our team is good friends with a guy who is a master fabricator, Randy Melton, so when he offered to help we didn’t turn him down. The first step in re-construction was to build a frame to support the new “hatch” area:

Image

Image

Image


Next up we cut a section off the old trunk lid and welded it back in place to complete the look:

Image

Image



With the frame completed and in place it was time to get to work on attaching the new Lexan. Clecos rock!

Image



Marking, trimming, drilling, and more clecos. BTW, no heat was used to shape the Lexan:

Image

Image

Image



With the basic structure in place, it was time for a little more function and aesthetics. I painted the inside trim black and we added a piano hinge so we could have an access hatch to the cargo storage area. After installing over 125 pop-rivets thanks to my new pneumatic rivet gun we had this:

Image

Image

Image

Image

Image

Image



The finished product….Prelude Fastback!


Image


Hopefully it was worth all the effort. I guess we will find out in a two weeks at the Lemons race at CMP.

:thumbsup:

any concerns about unibody flexibility at the rear shock mounts? Or does the added framing make up for any lost rigidity the rear deck sheet metal was providing?

The framing we added for the Lexan would not add any significant rigidity to that potion of the unibody, but rear stays of the roll cage had already stiffened that area prior to this modification.

ah, got it. Any ideas on bribes needed to keep from a 200+ lap penalty for making that thing look too nice? :lol:

Bowie Jr. and the "Goat" ran last month at RA and received no penalty laps in their Civic so I doubt these guys will receive any. I love this concept and idea and you guys executed it extremely well, kudos! :thumbsup:

Chump != Lemons

We had a residual value that gave us the room to pull this off. Plus it really
wasnt terribly expensive to do

I pulled that same picture and was going to posted when work got in the way. I think you need to put a motor from a model in the back.
