E46 M3 CSL Diffuser Installation Guide

Installation Tips & Self Installation Guide

To ensure a perfect 10/10 fitment we highly recommend dropping your E46 M3 off at a competent body shop which is fluent with aftermarket modifications.  That being said, a high percentage of our customers do the installs themselves with no issues whatsover.  We do not and will not accept returns on parts damaged while they are being installed, most body shops take responsibility for damages on their clock, so if you have never done body modifications we recommend taking your car to a shop.

Method 1 for 10/10 fitment.

Your bumper is high flex plastic, it should be removed or loosened up so it can flex around the diffusor for 10/10 fitment.  Since both the diffuser and your bumper have a bit of flex to them, you will be able to perfectly line up the two parts together.  Only hand tools are needed for this installation process and most of our customers have done it this way with great results.  We highly recommend bumper removal to get the best fitment.

This only takes about 15-20 minutes if you’ve removed your bumper before, if you take your time and don’t get flustered you will get OEM fitment easily and save however much your local shop decides to charge.  The diffuser is high quality and can flex decently as long as it’s not around freezing outside, same with the bumper, so you have quite a bit of ‘leeway’ while installing it wihtout it breaking, cracking, or becoming damaged.

Method 2 for great fitment.

Using basic hand tools and a floor jack, slightly loosen the bumper, but keep it on the car, and install the diffuser.  Our diffuser uses OEM mounting points so it’s very easy once you have the bumper loosened up and you can see even a few inches below the car.

Method 3 for easiest installation.

Remove your OEM diffuser and replace it with our CSL Style Carbon Fiber Diffuser without removing or loosening up the bumper.  A few of our customers have done this and we feel that by using other processes the over all fitment is much better.  Doing it this way will get the diffuser on your car but without increasing the flexibility of the bumper, you may not be satisfied with the final apperance.

Other installation information:

As with all aftermarket modifications, a bit of time may need to be put into fitment to give it an OEM appearance, most of the time these diffusors go on and fit perfectly, but sometimes ten or so minutes invested will make it perfect – nothing that you will spend hours upon hours on like our competitors Diffusers.

BMW E36 Corner Light Installation / Replacement DIY

Front turn signals on the BMW E36 3 series (1992-99) are easily the most commonly replaced or upgraded part of the car. Most people upgrade to the European style clear/white corners all around, and the fronts are the easiest and cheapest to explain. Since they are in the front corner, most fender benders or light accidents end up with the stock ones being broken, as they are plastic and don’t have much ‘give’ to them. This guide tells you how exactly to replace them in the easiest and safest way.

BMW E36 Tail Light Install / Replacement DIY

Most people who drive the E36 get rid of the sore looking amber lights all around, including the tail lights, which require replacing the entire assembly and not just the amber part (since the tails are one piece).  We offer them at a ridiculously low price, and they are high quality as all of our mods are, and the install is very straightforward and simple, only requiring probably 20 minutes for the total install and getting them to have OEM fitment.

BMW E46 CSL Trunk Lid Installation Guide

This CSL Trunk lid installation guide was found on e46fanatics, read through it in it’s entirety before going through with the install, as some parts are /more/ difficult than others, so be sure to read it through and make sure you entirely understand the full install.

This is my first attempt at a DIY and my first trunk install so hopefully the solutions I present will help some of you in the same position.

Mart and Paul at really came through with a quality product. As we all know aftermarket parts aren’t always going to fit 100% like OEM, with that in mind the guys at Euro-Spec are right around that 98% mark.

I recently installed my CSL Fiberglass trunk on my 2000 323i pre-facelift sedan. I was planning on just taking it to the shop and having them do the whole thing since they were painting my whole car anyway. I’ve always been an avid DIY’er so I decided to tackle this one myself. There were only a few fitment issues that I had come across, but nothing a trusty dremel couldn’t fix!!
