  1. Haha no worries, I'm certainly no expert thats for sure! Those wilwoods look quite nice. When the time comes to sort out the brakes I'll have to blow the dust off some of my textbooks and start doing some sizing calculations haha Interesting to know about the E38 MC, and thats a good point, keeping the brake size within the 17" wheels will probably be the biggest headache with any Big Brake Kit Done a bit more work on the car, made a decent start on stripping down my spare rear subframe So I can start building up a shopping list of all the stuff I'm going to need! Getting the bushes out seems like its going to be fun... as well as getting new ones in..
  2. There is a Bosch specific wiper set for the E34 because of the reverse hook on the drivers wiper, the part number is Bosch 602S. You can get them cheaper than that, especially when EuroCarParts have one of their sales on I've used them before and they're absolutely fine, I'm currently using some Valeo universal blades which also seem fine but I've got a spare set of Bosch's for when these go Alternatively you can swap an E36 wiper arm on in place of the reverse hook one so you can fit whatever blades you like, @Blackman has done this to his E34 recently I believe
  3. Cheers! No worries about the essay, I'm actually a Brakes engineer for an OEM manufacturer so I get to deal with this exciting stuff all day If I was doing a brake upgrade I would do both the fronts and rears as otherwise I'd run the risk of altering the brake balance adversely as you say. If going for bigger piston calipers I'd also consider changing the master cylinder as well to keep the pedal effort the same As far as I can see, the 540i brakes aren't much bigger than the 'standard' brakes if at all, but have a wider vent gap in the discs so should be better for cooling. Cooling must have been a concern with the higher speeds of the 540i given the brake cooling ducts in the bumper as well I'd argue against there being no benefit in upgrading to bigger OEM stuff, though for the cost to get M5 oppo piston brakes these days, you're probably not far off getting some properly big aftermarket calipers and discs, so its a bit of a case of diminishing returns with the OEM bits. Good quality parts are a good start as you say, I've heard of DS2500's before and they get good reviews. It all depends on what I end up using the car for really, I'd still like to keep it as a daily so track spec pads that squeal all day will become a nuisance haha, also I'd like to keep running 17" wheels for the time being which obviously limits how big I can go on wheels. The standard brakes aren't too bad to be fair, pedal feel could be better but thats pretty standard for a sliding caliper.
  4. After having a load of aggro from the refurb place with finishing off the centre caps, I finally got these fitted to my car
  5. I am terrible at keeping this up to date! Right whats been happening with the 520i? Well the Sports wood trim has mostly been fitted now, just got the gear stick surround and the little square that goes on the centre console then its all swapped over. I've also put some of the black interior bits like the sunvisors and overhead handles in as it means I can get rid of the grey stuff and get some space back in the house! I will eventually be recovering the headlining in black material (maybe alcantara?) so it will be like a Sport Touring. I've also got to cut out the holes for the sunvisor lights and nick the loom for them from the 525i. The auto dim rear view mirror wiring is also part of this loom, although I'm still not 100% sure mine is an auto dim but the wiring plugs match up so I guess I'll see what happens when I plug it in Aside from the interior, I gave the roof bars a quick test fitting The ends need painting but they fit nicely, just need to get a roof box or try out the bike carriers I've got and it will be super practical! I got my BBS RT/Style 19's refurbed, this was a right old saga with the refurb place not being able to get the plastic centre caps painted satisfactorily and having issues with paint matching.. In the end they've worked out ok but it was more stressful than I would have liked! But the outcome was pretty good Before After They'll not be on for long as the winter salt will be out soon. I'm currently trying to source some donor wheels to go on the 525i shell I have so I can take the 15" BBS off that to paint up as winter wheels.. Should be sorted soon I also noticed this on the front wing while cleaning.. Yayy... I've been dragging my heels badly on the 525i, got preoccupied with getting my RX7 back on the road and attempting to sell it to raise funds for BMW mods But I've sort of got a plan of action now, I'm going to push to get the remaining bits I need out of the 525i, and get rid of the shell. I'll then be able to get the 520i on the driveway and can start removing bits that need replacing (rear subframe, driveline, HVAC system etc.) In parallel, I'm planning to give the M50b25 a bit of a refresh, including M54b30 internals, M54 intake cam and a Non Vanos b25 intake cam for the exhaust. I've also been reading around this site and getting ideas about Eaton M90's.... I'm also going to drag my spare 525i rear subframe out of the garage and begin rebuilding it with the LSD and new bushes and a bit of paint etc. I'm also in two minds about brake upgrades, 540i brakes seem to be thin on the ground these days so I might just stick with good pads and discs and the standard calipers.. not sure yet Anyway, lots of plans, just need to put them into action!
  6. Nice tip on the E36 Wiper arm, I'll be trying that myself in the future Shame the M parallels didn't work out, but throwing stars will be a good look. If you were looking for other alternatives, I may have a set of 17" staggered Flat stars (style 16 from memory) for sale soon.. Also was the windscreen chap just London based? I've got a crack in my screen that I need to get sorted but I've read too many stories of people having trouble with windscreen guys not doing them properly! Car should look good with the Bilstein stuff on!
  7. I did a cruise retrofit on my 1995 520i not too long ago, I did start a thread on here which kinda went through what I had to fit. I did find my car was pre-wired for it, though equally I've got a 1994 525i Sport which isn't pre-wired for cruise! Essentially, you'll need to fit the actuator in the engine bay (bolts on using the same bolts as the power steering reservoir and there should be a electrical plug there if pre-wired). There are different mounting brackets depending on which engine the car it was fitted to came with, and the cables are a bit different also. Behind the passenger side lower speaker, there'll be a blue plug for the control unit Then under the steering column there should be a plug for the stalk, the stalk itself slides and clicks into place on the right hand side of the column. You'll either need to use the lower column shroud from a car with cruise, or dremel out the hole for the stalk (its marked on the back side of the shroud anyway) There are a couple designs of stalk, one for airbag cars and one for non-airbag. I believe the stalk with a 'bend' in it is the one for the later cars with airbags (thats what I have in mine at least). The part might be the same as the E36 but I'd cross reference the part number on realoem to be sure If your 525i is a manual, you'll also need to fit a clutch switch by the clutch pedal, its a bit hard to explain where it should go and there are a couple of different designs of bracket to hold the switch. I've currently just got the clutch switch plug bridged with a wire so I can't cancel the cruise with the clutch, but at some point I'll do the footwell gymnastics and try to fit the switch again! Of course if you don't have the prewiring then it makes everything that bit harder!
  8. It's how it is I'm afraid. The conical shape of a tapered wheel bolt or nut provides a centering effect without the need for a spigot ring. With 5 tapered bolts around the PCD, there is no way the wheel could move around the hub once tightened up. Some designs of wheel which don't use tapered bolts, do use the hub as the primary source of wheel location and in this scenario, spigot rings would be absolutely required.
  9. What load on the wheel bolts? Thats not how they work. The wheel is held on by the friction force given by the clamp load from properly torqued wheel bolts. The wheel doesn't rely on the bolts strength in shear. With tapered bolts you don't need spigot rings to stop vibrations, they'll merely aid fitting the wheels before you get all the bolts in. Also consider that most spigot rings are plastic, they won't be any use at taking any loads from the wheel.
  10. To answer your question on the hub spigot rings, since the E34 uses tapered wheel bolts, the bolts themselves will centre the wheel to the hub even if the spigot ring isn't fitted. So long as the bolts remain torqued up the wheel will be centralised on the hub
  11. Got my Style 19s back from the refurbers, just need them to finish off the centre caps then I can get the tyres swapped on from my flat stars and on the car
  12. Nice work on that rear axle refurb, something I'm contemplating having to do soon with my touring when I swap from a 520i to 525i rear end
  13. Oh and a 'before' picture for comparison Admittedly it had just come off the jack in this photo but there was quite an arch gap before I lowered the front anyway!
  14. I was in a similar situation to you last year when I decided to lower my 520i touring a bit on the front end, I did it via the 'cheap' route and to me its got the 'look' I was after in terms of the front arch gap This is with some 40mm lowering springs on the front (some 'AP Sport's off ebay). At the same time I had new top mounts and new dampers fitted on the front. I just went with reasonable price pattern parts for the top mounts and dampers. While this does give the desired look and for the majority of the time driving its fine, over bigger undulations and bumps, the front suspension can get a bit crashy as its quite underdamped. Like yours, mine isn't a particularly fast E34 so its not bothered me too much in the past year or so of daily-ing it! I can't give any advice on actually doing the job as I couldn't be bothered at the time and got a local garage to do it. It didn't look as though it should be a particularly difficult job though Hope this helps!
  15. Don't the lower spec later cars have slightly different top mounts on the front struts? (as well as the early/late strut differences?) My 520i has the small cap on the strut tower where my 525i has a bigger cap over the strut tower, I think the damper diameter might be different on these as well? Memory is a bit hazy as its been a little while since I changed the front dampers on my car!
