How to Fit a Duraflex Body Kit

With the wide range of exterior modifications that can added to cars, Body kits have taken over the import market by force.  That being said, tons of companies have jumped on board and have been producing fiberglass body pieces for many cars.

The problem with these body kits is they aren’t made very well.  The web is full of blogs, forums, and videos of the horror stories when car guys receive their parts in the mail.

When fitting the side skirts on to this 2001 Celica GTS we ran into numerous problems with the fitment and quality of the parts.  It’s sad to say but problems such as these are expected with these types of parts.  Here you’ll see the problems we encountered and the steps we took to fix them.

 

Damage During Shipping

Cracks

This is one of the biggest problems encountered when buying fiberglass body pieces.  Because of their nature, fiberglass parts are hard to ship. They are fragile, large, and almost always come from over seas.  If these parts aren’t packaged super carefully, cracks are almost inevitable.

Cracks like these can be easily fixed with a fiberglass repair kit that can be found at your local auto parts or hardware store. Make sure you add a few extra layers of fiberglass matting around the crack because that area will be more prone to cracking again.

General Fitment Size

Since these are mass produced sometimes the overall fitment can be slightly off.  We ran into this same problem on the celica because the overall length of the side skirts was too l short.  These were meant to slip over the outside of the front and rear wheel openings but in our case they were slightly too short.  If at first it does not seem to easily fit on the car DO NOT force it, you will risk the piece cracking.

I was able to solve this by removing a small amount of material from the inside of the side skirt where it contacted the wheel opening with an air die grinder and a burr.   Be careful using this method because it is easy to remove too much material.  If this happens you will have to apply more fiberglass to give the piece more strength.  

 

Mounting Body Parts

Usually when these pieces arrive in the mail they will not have predrilled mounting holes or included mounting hardware.  In order to get the fitment correct you will have to mark and drill the fiberglass, which can be tricky if you are by yourself.

Re-use as many original mounting locations as possible, these are by far the best option because the factory got it right when deciding where to mount them.  This will take care of some guess work to ensure each piece is properly supported.  If possible make use of original mounting hardware as well, as long as they didn’t break while you were disassembling them.  Even so, a small box of mounting hardware can be purchased at your local auto parts store for only a few dollars.

First line up your piece in the correct location.  This may take a few tries if trimming is needed to get the correct fitment.

With the wheel well liner pushed out of the way, use a marker to trace the factory mounting hole onto the side skirt.  Remove from the car and drill, this takes care of the front mounting location.

The rear did not match up with any of the factory so new holes had to be drilled through the side skirt and the inner fender.  When drilling like this make sure there is enough material on either side so it will not crack or split later on.

To deal with further fitment issues you will most likely need to buy automotive double sided tape that will be used along the outer edge of all of the panels.  This step must wait until after the parts are painted, so make note of where you want to apply the tape.  If done properly it will create a seamless fit that will look factory original.  DO NOT buy automotive double sided tape from your local parts store.  While yes it is labeled as “automotive grade” the adhesive is much weaker than the professional grade tape.  You want “Automotive Acrylic Plus Attachment Tape” this can be purchased online, it provides superior performance compared to any of the off the shelf products.

With the fitment done it is ready for body and paint work, look for a future article where we will show you how to properly prep and paint this body kit.

  • I have a 2003 mazda 6 I got good fitment of front and side skirts but rear end seems like it’s not wide enough,the corners push out under the tail lights. And I can’t figure out what it wants for a comfort zone for fitment. I’ve messed with this project for 3 months and can’t get correct fitment before I finish body work and paint.
