    Driving technique and its impact on pad deposits/"warped" rotors

    One typical example (MQB/Mk.7 rear axle, so with Ate caliper): Indisputably Galfer made (in Italy). That "Ate" might be somewhat misleading to the public. That said, most VW, Audi and Porsche (and some BMW, at least) rotors are made from SHW. My Porsche's rotors are SHW made (and Brembo made...

    Driving technique and its impact on pad deposits/"warped" rotors

    Tiguan Mk.1 I guess. Very most if not all MQB cars (Tiguan Mk.2) use to use TRW calipers on front and Ate calipers on rear. So TRW and Ate deliver the caliper to the factory including the pads. BUT: This does NOT mean these pads are TRW or Ate made. In fact TRW (ZF) and Ate (Continental) are...

    Driving technique and its impact on pad deposits/"warped" rotors

    Yes, that's fairly common. Did you check for runout? If you're interested to solve this issue this is the first thing I'd do. .

    Driving technique and its impact on pad deposits/"warped" rotors

    . Wife driving the family car and excessive heat? I doubt it. Probably just way more simple instead. I'd almost bet it's no deposits but just runout (resulting in DTV) due to poor (not so perfect) installation. .

    Ravenol RCS 5W-40

    . In my understanding RCS is a thicker and high SAPS brother of RUP (mid SAPS, it comes with BMW LL-04, MB 229.51, formerly VW 511 00, Porsche C40 and A40 before). I use to run RCS on my old 930 (no daily of course) for several years. OC every two years, way below 5000 mls. That said, I'll...

    Increase in pad slaps

    "Warped rotors" are a myth. The common problem is run-out (mostly due to poor labour) which leds to excessive DTV. That's what the driver notices, not due to "warping". .

    Increase in pad slaps

    I complete agree with you due to runout and measuring before running a new set of pads, no matter if you use new rotors or the old ones. However, "induction hardening" is BS. Car brake rotors use gray cast iron (commonly GG15, GG25 or GG26). You could harden steel but no gray cast iron. No way. .

    Increase in pad slaps

    Maybe BMW/Mini, but VW and Audi rotors use to have enough meat (MinTh vs new) for a second set of pads. For example 25 vs 22 mm. That said, I was quoted >$2000 at the VW dealer for my GTI two years ago, front and rear, rotors and pads including labour. No thanks, I'll do it myself this year. .

    Gearbox oil for mk2 Ford fiesta

    Gearbox oil for mk2 Ford fiesta

    While generally mixing mineral and synthetic is a non-issue you should definetly perform a full oil change anyway. Different oils mean different add packs, resulting in both weaker shifting quality and protection. I've been guessing Ravenol might harder to obtain yesterday, so just get...

    Gearbox oil for mk2 Ford fiesta

    . You're based in the UK I assume? Both oils might serve fairly. BUT: Why mineral fluid at all? Your Fiesta deserves a synthetic MTF. This manual is old. Gear oil got better since compared to 1988. From what this shop's offerings I'd try this one instead: Transmax Multivehicle 75W-90...

    Help pick an engine oil for 2014 Skoda Superb 3.6 VR6

    VW 504 00 or VW 511 00. M1 ESP 0W-30 or ESP 5W-30 or M1 ESP X4 0W-40 or Shell Helix ECT 0W-30 or Shell Helix Ultra AV-L 0W-30 (same). If you love to spend more I'd consider Ravenol VMP 5W-30 or Ravenol RUP 5W-40 (had VW 511 00 before but no longer). .

    Built in Phono stage question - preamp

    I wouldn't really call an MM cartridge "low impedance". Yeah, your, I suppose, Ortofon 2M Red will be happy with your integrated prepreamp. The AT-95E is crap anyway, vastly overrated. .
