The EASIEST Mod to Instantly Transform Your BMW!

Today, we’re installing one of the best first mods for any BMW—ECS Tuning’s Flush Kit Wheel Spacers—on my 2019 BMW 540i (G30).
Whether you drive a G20, G30, G80, F30, or another BMW model, ECS makes plug-and-play flush spacer kits that instantly improve your stance and fitment—no suspension mods required. Links below if you’re ready to dial in that aggressive OEM+ look.

In this video, I’ll show you the full before-and-after transformation, walk you through the step-by-step install process, and share tips for getting perfect flush fitment in under 15 minutes. If your BMW looks like it skipped leg day, this is one of the easiest and most affordable visual upgrades you can do. I vlog the entire process and show the exact tools that made this job quick and painless.

What do you think of the stance after the spacers? Do you run spacers on your BMW too? I'm stoked ECS Tuning took the guesswork out of sizing and included the right bolts! Links are in the description if you want to cop a set for your Bimmer. Let me know what mod you'd like to see next!

⚠ NOTE: That impact wrench I used is actually $50, not $25 like I thought. Still totally worth it—link's in the description.

👉 And if you’ve ever found BMW’s M Sport seats uncomfortable, I literally tore mine apart and made them better. Check out the seat mod video here:

I got a Remus axleback exhaust (Quad) with 102mm tips. To install it, you'll need an M550i sized diffuser. I paid $1, 700 for the exhaust. I was torn between the Remus and the MAD axleback but ultimately chose Remus for the way it sounds.

I'm also running a MAD catted downpipe, a BM3 Stage 2 tune, and an MST intake.

Man, those Icon headlights were the best. The 2020 G30 M550/F90 M5 are the best 5 Series in my book. It’s the sweet spot to have Pre-LCI, but with LCI mechanical updates. However, the taillights of the LCI are a must.

I just thought this car needed this exact mod this morning and boom you did it! 🔥looks sweet! I am going to do it too

[danrajful]

cant wait to see this lowered, it would sit really nice

[badseedtech]

Looks really clean, man. Would be great if you could share the OEM wheel spec. Size, width, and offset so we could get a sense of how the kit would look on different OEM setups. I’ve got a feeling the front might be too poked on mine.

[zerotwo]

can we see catless downpipes installation, bm3 stage 2, power and numbers?

[bluestonemetallic]

…when I got my front/rear Eibach wheel spacers, was told to use the anti-seize lubricant to avoid rust welding between the spacers and the hubs!…I recently did the stud conversion from MMR kit (now MMX)…swapping wheels/tires is a breeze now.

What about the driving experience? It got worst? I also heard you can get issues with the xdrive. You heard something?

[mark_nz]

Sweet Freedom! You running square? Handle all good?

[ProdbyRusoo]

Love the way these look on the car man. I've been thinking about doing the same exact setup on mine. I was looking at the ECS tuning flush kit but from what I've seen its kind of overpriced? I may be wrong but from what I've seen you can buy the same thing for 100-200$. They do make it easy with the set I am not saying the kit itself is bad at all.

Don’t delete the muffler… trust me just delete the resonator. Subtle difference not overwhelming
