:: ECS Tuning :: NEW!! Aggressive Flush Fit Kit | B8/B8.5 S4

[ECS Tuning-Audi]

The ECS Tuning Aggressive Flush Kit was researched and assembled to bring your wheels out for the best fitment and look. Designed to work with the OE 19" 'Peeler" style wheels, this kit will give your car the aggressive flush look it was missing from the factory, and gives optimal fitment for lowered vehicles.

Our ECS Tuning wheel spacers are designed and engineered in house by our leading R&D department to make sure of the perfect fit. This kit feature a more aggressive 10mm spacer for the front wheels and may cause rubbing on vehicles that are considerably lowered.

I can contest that this kit is great, use it for my winter setup and they do a great job filling the wells

I'm on stock 18s, going to lower on HR Sport Springs. What spacers do you recommend?

The best way to understand which size spacer you need, is to simply measure from the top outside edge of your tire to the inner lip of your fender. This will give you the best idea on how much size you have to work with, and to decide on how much your wheels need spaced.

Here is a diagram that might help as well.

Which is only possible if your car is slammed or you somehow compress the suspension so that the tire tucks into the fender to get anywhere near an accurate measurement.

This is a new "package" with a thicker front spacer. Appears to be the same rear spacer as the old flush fit kit.

Gotcha, I have the original package I think it was 8mm fronts, and 12.5 mm rears.

Not really. Just use a straight edge.

[MagillaGorilla]

So it is 10 and 12.5 instead of 8 and 12.5.

Any chance of pics on stock ride height?

[ECS Tuning-Audi]

Correct. This is our "aggressive" kit for those who want 10mm spacers up front.

Unfortunately we do not have any pics of this kit installed on a stock height vehicle.

I will have pics of the stock height with the "old" spacer kit come winter, take it you don't want to wait that long.

You guys make me laugh. You already researched and failed. The only reason this new kit exists is:

A) The original flush kit (which I have) is not flush at all.

and

B) People complain that the 8mm spacer makes their car vibrate, which the 10mm fixes.

I wouldn't exactly call that research, but hey, at least you finally listened and made a proper flush kit.

Ouch LOL

For what it's worth, I am using 19x8.5 et43 wheels with 10mm front spacers and the fitment still is not very flush, although the camber is around -1.9 degrees due to my ride height and not having adjustable control arms installed. But the missing part of the flush fitment equation might be that adjustable control arms are required to get back to the -1.5 to -1.6 degree camber range to "fill out" the space between the top of the tire and the fender.

Also FWIW, my 19x8.5 et43 wheels with Michelin PSS 255/35 tires and 10mm spacer rubbed wildly on the small pinch weld thingy that protrudes from the passenger side rear fender where it meets the bumper. I had to go down to a 5mm spacer on that wheel to avoid rubbing. My rear camber is around -1.6 degrees. I have a feeling that the way they are getting away with a rub-free setup using 12mm spacer is by running more negative rear camber than I am, and maybe even by using the OEM Continental ContiSport Contact3 summer tires which run way narrow compared to the very popular Michelin PSS in the same size. Be warned!

EDIT: My car with the setup described in the first paragraph above:

[Vogz]

Steve, I had the same problem as you did. My car with stock 19in Rotor wheels and Bridgestone S04 tires would rub in the back with the 12.5mm spacer BAD. I went down to a 10mm and it still rubbed so I gave up and took the spacers off completely.

Any effect would be positive due to wider track.

Just put them on a couple weeks ago. Took some quick flicks.

I am on stock suspension for now..

I pointed out this issue here: http://www.audizine.com/forum/showth...1#post11696028

I even made a video showing this issue!

I put the video up, and a little over a month later, we now have this "aggressive" kit. I'm already a happy camper as I went out and bought 10mm spacers from ECS on my own. What I'm pissed about is that they still fail to admit that 8mm spacers don't fit properly and they continue to mislead customers who are unaware of this.

[FWP!]

I assume these will work fine with the optional black-optics 19x8.5" wheels?

[ECS Tuning-Audi]

We've been selling 8mm spacers for years. That being said its highly debated that since 8mm takes up about the majority of the factory hub extension centering the wheel is difficult. This is old news, it has been know since people first started putting spacers on Audi's. It's not that they don't fit properly. There's still people on this forum that run 8mm with no issues at all. So if they fit improperly don't you think that every person that ran 8mm spacers would experience this? It could have also been that the tolerance on some 8mm spacers with the wheel centric lip (which is to aid in centering the wheels) was slightly out of spec. Customer service is more than happy to work with customers experiencing any issues with our products.

As for the comments about how we "failed to do research" etc etc.. These kits are put together as a convenience based on what we feel is required for a flush fitment. We originally chose 8mm spacers because we wanted a kit that would give a flush fitment on stock or lowered vehicles and did not rub. Can you run 10mm? Sure, but depending on which tires you run, camber, how low your vehicle sits all could effect if you will have rubbing issues. 10mm was a gamble.

Seeing that many customers were requesting 10mm spacers for the front we just put a kit together again for convenience.

Prior to these kits being made you would have to do all the work. I would get multiple PM's asking "what size spacers do I need for a flush fitment" We took much of the guess work out and made it easy for those less experienced with using wheel spacers to get a flush fit on their vehicle.

Anyone is MORE than welcome to purchase spacers and bolts individually and get the exact fit YOU want.

Jason, wondering if you could help me (and possibly others) understand why the 8mm spacer has slop in the wheel itself as Acejam pointed out in his video, and how the 10mm spacer does not? I think I follow your response that the lip on the 8mm spacer is smaller because the "system" utilizes a portion of the factory hub extension and thus the lip on the 8mm spacer is more shallow? And is this inherently a potential problem with 8mm spacers, regardless of the manufacturer, since Acejam is comparing only ECS products?

Like I mentioned it could have been that the tolerance on the spacers he received was out of spec. Which would deem them defective, which we would gladly accept them back if he sent them in and we ran them against our figures and they proved to be out.

The lip is smaller because there is simply not enough material on an 8mm to create an "extension" like that of the 10mm. You have to remember the factory hub has to fit inside of this spacer and it's just thick enough that it doesn't even poke through. You would need more material to machine and extension like on a 10mm spacer. 8mm only allows you to add a wheel centric lip.

Thanks for the explanation! Then in theory, there shouldn't be that slop, that Acejam is able to show in his video, when you put the 8mm spacer behind the week? And if there is, we should assume that was a defective spacer? Is it possible that there could be similar slop also based on the wheel that maybe has a "bust" in its spec as well?

My suggestion would be to test each spacer in the same wheel for consistency as well as vice versa. If you notice differences you can then try and isolate it more by trying it with a third wheel.

It is possible some OEM wheels may have a slight variation in the centerbore too.

Jason

[Lensch09]

So, how is this "aggressive" flush kit any different than the "standard" flush kit?

Also, when will you be offering the "Mexi" flush kit?"

Edit: I see its a 10 up from the 8. Still in for mexi-flush kit when available.

That's like putting an 8mm bolt into a non-threaded hole that's made for a 10mm bolt. Sure, it'll "fit" and be snug "in and out" of the hole since there is a nut on the other end to help keep it tight. However, the hole is bored for 10mm, and so it's possible for the bolt to move side to side. If that bolt isn't exactly 100% centered perfectly, you're going to get wheel vibrations.

Sorry, but I call that not fitting.

8mm only allows you enough material to create a HUB centric lip. There isn't enough material on the spacer to protrude into the wheel hub far enough for stabilization, so it's most certainly NOT wheel-centric.

The optimal spacer, like your 10mm one, is both HUB and WHEEL centric. The 8mm ones are only hub centric. They have a "wheel centric looking" lip, but it's not long enough, and that is exactly what's causing the problem.

The extra material on the factory rotor hub and 10mm spacer allows for the wheel to center and stabilize. Without this, you get vibrations. This is critical! Why is ECS selling a product that removes this stabilization and claims that it is OK?

I've also tested other ECS "v2" 8mm spacers and they also have the exact same problem. There is no defect here, they just don't fit, plain and simple.

The spacer is not defective, it will always vibrate unless you get lucky and manage to center it perfectly. Why bother struggling with having to center it? Just get a proper fitting spacer that does what the factory gives you - a stable smooth ride and a centered wheel 100% of the time.

[kobrian85]

Sorry, but I call that not fitting.

I follow your logic, I guess it's just not abundantly clear to me why the 8mm spacer can't have the proper "lip" diameter to properly marry up to the wheel. And why a 10mm spacer can be manufactured to allow for proper fit-up...

8mm only allows you enough material to create a HUB centric lip. There isn't enough material on the spacer to protrude into the wheel hub far enough for stabilization, so it's most certainly NOT wheel-centric.

The optimal spacer, like your 10mm one, is both HUB and WHEEL centric. The 8mm ones are only hub centric. They have a "wheel centric looking" lip, but it's not long enough, and that is exactly what's causing the problem.

Again, I follow, and maybe it's my lack of experience with spacers, but your video seems to indicate that the lip on the 8mm spacer is simply too small in diameter for the wheel hub, thus the slop, is that incorrect? Or is the lip nearly non-existent because of the lack of material for which the 8mm is machined, and that's where the slop is created?

[Acejam]

There is a smooth beveled lip on the 8mm and that's it. The 10mm has the bevel and then necks down to the longer extension piece. This extension piece is the crucial part. It's non-existent on the 8mm spacer and is the root cause of the issue.

Compare pics of the 8mm and 10mm ECS spacers and it should be more noticeable.

Gotcha, thanks for the education!

Is this the same issue with other 8mm spacers by different manufacturers? I understand the point of using smaller stock for smaller parts (and thus becomes a matter of cost), but it seems that with larger stock that allows for additional machining and thus gives a proper extension for fitment, would make for a better product. Maybe a longer extension on an 8mm spacer would be too thin and not structurally sound when the dynamics come into play...?

I feel like I'm straying off course here...

Thanks again for the explanations, Acejam!

Great video man! I must have the V1 8mm spacers because there's no lip on mine at all.

I had a small vibration on my peelers at around 60mph that I attributed to my PSS as well. Read on to see how I was wrong.

Today I put on a set of 19" titanium rotors just like the ones you have. I swapped the PSS onto them. Took the car on the highway and it shook like crazy at anything above 60mph. My first thought was the place balanced the tires wrong, but they told me when they installed the wheels that the fronts we're going to vibrate because of the spacer. I ignored them and said put the spacers back on anyway since I've been using them with my stock peelers and it wasn't too bad.

So I went back home and popped all the spacers off myself. Put the wheels back on the car with no spacers. Took it on the highways agin and smooth as silk! So now I know the tires were balanced correctly.

Went back home and put the ECS 12mm spacers in the front (this might be too much spacer for the front, I'm still deciding), and I threw an H&R 15mm spacer in the rear. Took the car back on the highway again and still nice and smooth!

So the more of the story is, the 8mm spacers are complete garbage, BUT for some reason they seem to be even worse on the titanium rotors.

Sorry if I’m reviving a dead thread. But in conclusion, forgetting about the 8mm, are the 10mm (front), 12mm(rear), better? Meaning no vibrating?

I used this kit (10mm front, 12mm rear) for a couple years with stock S4 Rotors and didn’t have any vibration issues. Stopped using it earlier this year (different wheels) and still have it but haven’t got around to posting it for sale. Thanks for reminding me lol. PM if interested.
