Comment(s): There are several sellers of this lip on ebay. If you cant find one then just wait a week or so and it will be restocked. If you paid more than $70 shipped, you paid to much. Average pricing is 64$ and lowest is 59$ I've seen in the past 7 months.

Comment(s): I used 22 Rivet/Washer on this project including the ones I miss pulled. Actual amount on the bumper is 17. I bought 50 because it was almost the same price as 25 and you have more left for future projects or mispulls.


Prep Work (optional)

Step 1 – Lip Prep
When I got my lip, it was covered in a bit of oil from the manufacturer. I used a bit of rubbing alcohol to clean the entire lip down and made sure there was no cracks or abnormal bends.


Step 2 – Lip Color
This is a perfect time for you to prime and paint your lip if you want to color match it or just be different. This way you can get it in all angles. I personally used these at the bottom start with primer, then the base coat, metallize etc

Step 1 - Bumper Removal







Step 2 - Measuring and Drilling the holes

Place the bumper and lip on boxes or stands.


Make sure the bumper bottom area is cleaned off with rubbing alcohol or non oil solvent.


Measure and mark a dot from the center of the bumper notch to the edge about 3.5" or a maximum of 4.5" This will be where you match the center of your lip




Measure and mark a dot from the both sides of the bumper that has the largest hole shown to the lip about 3.25" or a maximum of 4.25" These three measurement will be the mod




So the marking should be close to this


Then place the lip on making the same marking as close as possible. Advice is to find the center of the lip first and go out from there.


The bumper and lip should look like this in the process.


Take the 3/16 drill bit and drill through the lip. You can use different dril bit according to the rivets you buy.


Afterward, drill the marking from the lip, and make sure it hits the second marking on the bumper for best accuracy.

Make sure corresponding target is made. Do no redrill close by is unsatisfied with the hold. Instead move .25" and do another hold.

Step 3 - Mounting The Lip On

Take the 3/16 rivet and washers your purchased and insert it through the lip.


Look for the corresponding hold and pass it through that as well.


The rivet should stay in place as you get the washer to be placed on the other side.


On the other side you see this as the rivet is poking through.


Place the washer making sure it is firmly grounded and no debris or plastic is in the way


Firmly press the rivet tool on the other side while holding down the washer's edge and cramp/pull the rivet. Video example can be seen in Step 5.


You will soon after repeat and rivet areas that seem loose or should put pressure on. This is what I ended up with after completed rivet fastening the lip.


All the insides should look secure.


I ended up 5 on each side and one middle for the bottom mount.


Step 4 - Cutting Lip Ends Off


Step 5 - Fastening Lip Sides


Step 6 - Weld Lip Ends

Coming soon...

Step 7 - Reinstall bumper.

Up to now, if everything was followed, you should not need to modify anything to put your bumper back on. So just reverse Step 1.

Congrats, you completed your Custom STI CS Style Lip









**End**

Keep asking questions as I will add them to the FAQ for future references. I hope this was a decent DIY, if so I will do more in the future.

The video is great and gives great detail. My guess is that everyone else is waiting for you to completely finish up the DIY prior to asking anything.

like the side skirt area you know?

this makes the entire front end beautiful. end of story.


I thought about cutting the entire sides off as well but then it would leave a weird hollow gap. Also Im thinking to pair this up with the HFP sides which flows pretty nicely once I match paint it fully
