More than a year since I updated this. Car hasn’t done many miles but a heck of a lot to report. Certainly a bit more than the usual annual MOT update…
After buying all the gear to do the 18z upgrade a while back, then selling it all when I changed my mind, I’ve had a hankering to revisit the subject. I didn’t go with the 18z’s as it would have prevented me from using the standard 17 inch wheels. So I’ve now opted for some 17z’s.
I picked these up off ebay for the very reasonable price of £150 delivered. They arrived and they were pretty much as expected – old, dirty, crusty but overall not in terrible shape.
I gave them a full strip down and rebuild with all new parts. I’ve never rebuilt a set of calipers before so found a couple of useful videos on Youtube (oh what did people do before the internet). I was surprised how straight forward it all was. Aside from one of the link pipes, which I had to proper butcher to get out, they came apart with relative ease and rebuilding them was even easier.
After fully dismantling them, cleaning them up and painting them, I was left with this bundle
And here’s the finished product. Delighted with how they turned out.
I’ve gone with Volvo V70R discs which are perfect for this set up, aside from the bolt holes. They need to be opened up slightly (16.8mm to 19mm) to suit the B5. I initially went down the lazy route – I have a engineering shop near-by so popped in to see if they’d do it for me, but they didn’t want to mess with any braking components, fair enough. So along to the local Toolstation I went and picked up a 19mm drill bit. Job done for less than a tenner (although I’m sure a professional would have been neater).
There’s loads of info online on this upgrade but here’s a list of what I needed and the cost involved:
Brembo 17z calipers - £150 (eBay from someone breaking a Cayenne)
Frentech Braking 17z rebuild kit - £110 (seals, dust covers, pistons and bleed nipples)
Link pipes - £28 (custom made from someone on eBay)
Febi pad fitting kit (182292) - £15 (Autodoc - PN)
Brembo discs (09.8614.11) - £105 (Autodoc)
Brembo pads (P85069) - £80 (Autodoc)
SID Motorsport mounting bolts - £35
HEL Performance brake lines (AUD-6-360) - £54
ATE Type 200 Dot 4 brake fluid - £15 (Autodoc)
Misc bits - £60 (paint, decals, brake cleaner, grease, drill bit etc)
Around £650 in total. For that, I have a fully rebuilt set of 17z’s as well as brand new discs, pads and all fitting hardware. I’d say that’s decent value for money for a BBK.
Anyway enough about brakes. I mentioned a while back I’d been gathering parts for an underside overhaul. To say this grew arms and legs would be an understatement. I started off gathering a few select bits and pieces as and when they popped up for sale, but somehow ended up with this absolute haul…
So yeah, I got a bit carried away. I also made the mistake of keeping a spreadsheet of everything I spent – that was a bad call. Eyewatering doesn’t cut it. I’ve probably missed some stuff but I did the following:
- Front & rear subframes blasted and powder coated (front fitted with Verkline polybushes, rear has solid bushes)
- Front subframe support brackets and cross brace also blasted and coated
- All uprights blasted and powder coated (rears fitted with Verkline lower polybush)
- New Lemforder front arm kit with inner & outer tie rods (new rack boots too)
- New KW V1 coilovers
- All 4 driveshafts refurbished
- New ABS sensors all round and headlight levels sensors with new arms
- Fully rebuilt 17z brake set up with new discs, pads, braided lines, fitting kit etc.
- Fully rebuilt OEM rear calipers with new discs, pads, OEM shields, braided lines etc.
- Front & rear H&R arbs blasted and powder coated (came out a beautiful merlin purple!)
- New arb bush brackets front & rear
- Engine mount brackets blasted and coated
- New 034 engine mounts
- Gearbox mount brackets blasted and coated
- New 034 gearbox mounts
- New OEM undertray rear mounting bar
- New handbrake cables
- New Powerflex snub mount with blasted and powder coated bracket
- Front upper suspension brackets/top hats
- New OEM diff crossmember
- Diff support bracket blated and powder coated
- New Verkline diff mount
- New exhaust hangers all round (rear hanger bracket blasted and coated too)
- New section of rear brake hard line
- Rear upper arms blasted and powder coated, fitted with Verkline polybushes
- Rear lower arms blasted and powder coated, fitted with Verkline polybushes
- ABS brackets blasted & powder coated
- OEM rear turrets imported from America (proper mint)
- New Lemforder rear drop links
- New Meyle rear tie bars
- New OEM headlight sensor bracket
- Stainless steel fuel tank straps
- Various new OEM fuel tank guards/shields
- And of course, a whole host of new nuts, bolts and washers (mix of genuine and aftermarket)
Parts above came from across the globe – America, Germany, Poland, Lithuania and of course all over the UK. Websites I found useful for sourcing stuff – Audi Tradition of course, riauto.org, rscarparts.de, Autodoc, WOTMotorsport, and of course AudiSRS!
I spent a bit of time ceramic coating whatever I could before it all went on, no harm in adding a bit of extra protection before it all went on.
Although not really part of the underside refresh, I also bought a new (to me) exhaust for the car. It consists of a set of Originiall Fabrications 3” downpipes mated to a 3” system made my Stainless Creations in Falkirk. I got this from Ross (rosscopeco) who I know went through a few systems before he settled on this. I was looking for something a little quieter than my current system that still had a nice purr to it; I’d never actually heard this system but seemed like it would tick all the boxes.
It didn’t even cross my mind to fit all this myself, well beyond my skill/patience/knowledge levels, so I sent the car down to Jimbo a few months back. Made the 3 hour drive, dropped the car off, left all the parts, and headed home. It was actually nice to have an empty garage after having all this cluttering the place up for so long, probably took me over 2 years to accumulate it all.
With it being winter I didn’t overly miss the car for a few months, probably wouldn’t have left the garage anyway. Jimbo worked away on it when he could and kept me updated; no super nasty surprises but we did find one of my rear springs was snapped, so just as well new coilovers were part of the parts bundle. Also found a fair amount of rust in the arches when the liners came out.
Needless to say this all got dealt with before any new parts went on.
I actually don’t have too many photos of how well it turned out but here’s a few to whet your appetite!
Jimbo slapped a coating of clear waxoyl on everything as well which should keep it looking fresh for as long as possible. I need to get the BBS wheels back on soon so I’ll hopefully be able to grab some more photos when the cars jacked up.
I also had a new radiator fitted while the car was down there as I’d noticed a very slight leak over the previous year or so.
I collected her last week and brought all the old parts back up in the daily driver. Exhaust, coilovers and front arm kit all sold but I’ll be sending the rest off for blasting and powder coating in the coming weeks if anyone is looking for some shiny refurbished parts!
Back up the road and she was cleaned and straight in for an MOT a few days later. ‘F**k me mate, it’s like MOT’ing a 3 year old motor’ was music to my ears.
Glad it now looks as good underneath as it does on top. I’ve spent more on this refurbishment project than I did on purchasing the car 7 years ago… and I’ve questioned many times if it would be worthwhile and the comments from the MOT tester were at least some kind of validation! I’ll never get anywhere near my money back if I did sell but its done now and I’m happy with the car.
Got a few little niggles to sort out now but nothing major.
- Car needs properly set up and tracked before I can really drive it. I’m booked into Kenneth Brown Motor Engineering in Hillington next month, heard good things about him.
- I have a slight rattle coming from somewhere at around 3,000rpm. Jimbo thinks part of the exhaust system, which seems logical, but I can also hear a little rattle coming from somewhere while driving over rough ground, audible when the cars freewheeling. So it could just be a loose shield somewhere or something. I’ll need to investigate.
- The exhaust sounds lovely, so nice and quiet when cruising but a lovely growl under load, but it sits tight against my rear valance. Its booked into Cal-tek in Ayr next week to get the positioning tweaked.
- My ABS/traction control light has popped on a couple of time since I got the car back; doesn’t seem to be any rhyme nor rhythm to it. No particular speed, time and not necessarily under breaking. Will need to give it a scan and see what corner its coming from but my laptops on the blink.
- I also noticed the headlining was sagging when I got the car back to that’ll need to come out and get re-glued.
Hopefully I’ll have all that rectified in the coming months.
Lastly, as if all that wasn’t enough, I bought a full K04 kit for the car, again from Ross’ breaker. OEM BW K04 turbos (done around 35k miles from new), OEM RS4 inlets, OEM RS4 intercoolers and shrouds, hoses, Deka injectors, 044 fuel pump and 034 Motorsport basket. Price was very fair so seemed like a no brainer. Brakes, exhaust and clutch are all ready for the upgrade now, so this should be pretty much everything else I need should I decide to upgrade in future (that’ll be another visit to Jimbo).
725 miles covered in the last 12 months, somehow not my lowest! Although around 300 of those were the round trip to Jimbo…
