RS5 assembled suspension

[FlyS4]

RS5 assembled suspension. Front set up has about 5k miles. Rear has about 1k miles. Very clean- like new without any issues. This will fit B8 and b8.5 A4, A5, S4, S5 and of course the RS5. $1000.

As a heads up for those looking to by these, rs5/s4/s5 front ends are much heavier and due to that, audi puts a different type of spring up front. With that in effect, it may cause the front end of your a4/a5 to be higher than usual.

Thanks for your concern but it isn't true.

Is that an S4 in the picture or did you put this suspension in the Camry?

Seriously, though - Can you explain how Slick's statement isn't true?

[FlyS4]

If anything the front is lower than an original S4 stock ride height. It is not higher. Speaking from my personal experience.

This makes no sense, you need a stiffer spring for the heavier motor. If you put this on an A4 you'll be sitting higher than stock. Sure, it'll fit though.

If it makes no sense, let me try to explain. But first do you know the weight difference across these 3 engines you mentioned?

To address your comment about A4 being higher than stock is absurd. A4 stock suspension sits higher than all S4, S5, and RS5 that’s unless A4 is an Sline where it shares the same suspension as base non EDS S4. Furthermore almost all aftermarket is selling the same suspension for the platform regardless on the engine and transmission configuration. For example bilstein pss10 are the same part number across the whole platform. Same goes to the lowering springs. I even provided the picture showing that RS5 suspension is no higher on my personal s4. Please, you are engineer, research the market before you try to ruin my for sale post.

Sort of, the spring rates are different depending on the axle weight range. Hence the multiple color codes across the b8/8.5 platform springs, which aren't very visible in your photos. We're more concerned with A4 fit than S4.

Color codes are not platform specific but rather lower and stiffer on the account of The H&R line of lowering springs ranging from OE, Sport, and super Sport are all developed across the whole b8, b8.5 platform. There is no different spring rates across a particular spring for a specific engine.

So there's no spring rate difference between a 6MT, 6AT, and and 8AT both with a 2T motor? Not to mention throwing 3T motor and DSG trans springs in any of the latter? OK...

That’s right. In aftermarket suspension or lowering springs there is not. You better tell me why base s4 suspension is used on an s line A4. According to your theory the A4 will rise like sq5 up front.

We are talking OEM suspensions. You'll notice all the springs have a different part number (two digit letter) which equate to different spring codes. You can not have a spring that achieves the same height/damping across a varied weight without changing the constant. Brush up on Hooke's law.

[FlyS4]

You are missing my point. Height wise the difference is negligible if any. That is why aftermarket isn’t worried either. You still failed to provide engine weights.

2L is a cast iron around 315 lbs. Unsure on the S4

Wouldn’t imagine there is a big difference. V8 has 2 Extra cylinders, however, V6 supercharged has a supercharger, heat exchanger and a pump that cools it, which weighs a considerable amount.

Just by comparing the whole car curb weight it’s within 100-150 lbs difference for the whole car.

No on is trying to shit on your thread bro, and i wish you the best of luck on selling your items. But there are a couple of threads on this topic and most have come to conclusion that it does infact raise the front of the vehicle. It may not do it so much on an s4 using rs5 springs but the a4/a5 front end is much lighter. Anyhow, glws

Can’t speak of the A4 because I haven’t tried it. Sounds like b12 kit would be perfect on the A4 in that case. I will have that for sale soon.

What I do know- like I said. Every kit out there is cross compatible across all the engines, so if it was so high up front it would affect every single aftermarket set up.
