Just downloaded the app and should be receiving a package tomorrow! Ape FTW.
Is it in yet? Is it in yet? 
In…
So far so good. 4 days of sitting and it’s only lost 2%. oh…and 45lbs! pics to come shortly
Sorry for the delayed response. Haven’t used the car in a few weeks and wanted to give a good listen. The answer is It works okay. The woofer (sub?) still works but has greatly diminished bass. The nature of a Good bass from woofer/sub is to isolate the wave of the front of the speaker from the sound wave of rear of the speaker to make it efficient. Hence why woofers come in enclosures, trunk or speaker box. In the RS5, with the removed seat, the efficiency is greatly reduced but not completely because although the seat is removed, the rear of the speaker is sorta in a different enclosure. Ie trunk.
Anyway, I much prefer the sound of the engine so no priority in updating Audi system atm.
Good older thread on here I thought I’d bump back up. Obviously the JHM Stg2 tune is probably the best performance item you can do but it works better with Headers? Lighter, free flowing exhaust. Best single item for weight if you have OEM rotors is a set of OEM or aftermarket Forged wheels, stronger and lighter. I love the Rotors look but couldn’t stand the weight. They are now on my S5 but even that car will get Forged wheels soon. For weight I’ll add in the complete removal of the SAI system, weight in the far front (twin airpumps) plus hoses going to the back of the engine, plus it cleans things up and looks better. I posted elseware but the ECS Carbon Fiber rear Spoiler was 30oz less than the plastic OEM, almost 2lbs there. Seibon Carbon fiber hood was worth 20lbs+, Front higher weight but a pretty sturdy hood. There are lighter Carbon fiber hoods out there (really thin) but the Seibon could be said to be close to an OEM quality item. Ask Carbon rear diffuser, I’ll weight the OEM one this week but the Ask Carbon is sweet (Thanks Ape for the recommned). I decided I wanted a nice Carbon Fiber engine cover as my original plastic looked a little faded, the Nitrocomposites (UK) piece is almost 1lb lighter. Titanium Wheel bolts, you can get them on sale from USP Motorsports or ECS tuning for around $200 as set and they don’t corrode (sorry but if you live in the NE your Salt can probably corrode anything).

Hahnmgh63, you bring up some great suggestions! I will start looking into the SAI delete now that there seems to be some info on it. I’m a big fan of deleting unnecessary weight ESPECIALLY in the front end.
I’m going to be doing the SAI delete thanks to @hahnmgh63 and his help. I’m just waiting for my gaskets and I’m ready to go !
The plates I got of eBay for 10 pounds inc p+p they are for an e46 bmw and are egr delete plate’s but are the right size exactly with about 4/5 mm thickness, the oem gaskets cost 3 odd pounds so it’s an easy cheap mod if you do it yourself 
GERMANBrew, when you removed the rear seatbelts did you have to code them out to keep from getting and Airbag warning? I know the rears have Pyro initiators on them so they’ve got the Yellow plugs. You are right that they are a real pain to remove. I replaced a bad one on my S5 a couple of years ago but now I want to remove them from the S5 & RS5, not like I’m ever going to put someone in the back seat.
Hahn, I can’t give you a definitive yes/no about the rear belts because I have an “AIRBAG” light on already due to the Wingbacks. I did scan the car though several times and I don’t recall seeing anything seatbelt related. I’ll check again this summer when I pull the old gal out of the stable.
I’ve been on the hunt for OEM RS5 wingbacks without much luck.
Besides eBay.co.uk any suggestions on where else I should be looking?
I found mine on EBay.DE the German site. Sometimes RS246.com has a set. PartsBy Topher on IG might be able to help as well. You have to be patient and ready to go. It took me 18 months to find and secure mine.
Thanks!
We will see what pops up =D
Are they still $5k?
They are still $5K and UP. Inflation right?
The other option would be to go with the Recaro CS’s from AMX Performance out of Poland. He reworks the covers to your specifications.
did the OEM wingbacks only come in B8 RS5’s in EU? Or also B8.5s?
They came in 8.5’s also. We Americans are too fat to get them.

Same with the C5 RS6’s. I had to buy a set for my RS6 from Germany a few years ago.
Rs4’s had them as well b8 & b8.5’s
Rs4 seats will work in the rs5?
Any modifications needed?
I may have found myself some rs4 wingbacks.
RS4 ones will work just as well other than having the wrong stamp in the headrest.
Mine are from a Cabriolet RS5 so those have a latch mechanism integrated into the “harness holes” in the shoulders area. It’s kind of slick and let’s you fold the seat forward with ease. I think the R8 ones have that as well.
Issues wise…you will get an “AIRBAG” light in the cluster and you will have the “Passenger Airbags OFF” constantly illuminated. There are fixes for both. I’ll get around to those someday.
