  • Rear Tyres Unavailable 265/40/ZR17

    Unfortunately the cost of importing from USA is prohibitive. Michelin Classic has Pilot Sport 2 - 275/40/R17 which fits fine (I have fitted these last week). These are available in the UK via Blackcircles, Longstone Tyres, and Beaulieau Tyres.

  • Rear Tyres Unavailable 265/40/ZR17

    I cannot find a supply of 265/40/ZR17 tyres for the standard 10J rears. The only tyre I can find on the internet is the Hankook Ventus S1 Evo K107. This is being sold by "Tyres Guru" and Debs Blythe managed to get two from them. However, when I ordered two, they contacted me and said my credit card payment had not processed (a lie as there is nothing wrong with my credit card) and I must transfer the funds directly into their bank account. This sounded alarm bells so I did some online checks and found loads of bad reviews for this company, which is just a front for Delticom AG. This company has many internet "shop windows". Common complaints are failure to supply, failure to refund or asking for more money as the price has gone up. One to be avoided.

    However: This leaves us without any alternative for our original fitment.

    My current tyres are Dunlop SP Sport Maxx, but they no longer make them in this size.

  • 3.91 LSD Coming Up For Sale

    I am going to swap out the 3.91 Limited Slip Differential to take my 840 CiSport back to stock 2.64 before I put it up for sale. I am now retired and hardly use my car, just a couple of hundred miles in the last two years and can no longer afford to keep it.

    I bought the diff from DickB (member of this site) of Holland and have had great fun with it in. It was originally from an E34 M5 3.6. Part No: 33102226601

    My car was transformed with it fitted, really hot off the line for acceleration and with the LSD, no tyre slip. It corners as if it is on "rails". Mid-range acceleration is instantaneous, without need for kickdown.

    However, I know that the best price I will achieve for my car is in standard specification so hence the swap over.

    If anyone is interested, please let me know - I am looking for £900 for this rare differential.

    There are a few threads on here about the 3.91 diff. You will need to swap over the rear cover, as I will put it on my 2.64 diff. The bolt holes are identical so this is no issue.

  • Diff. Swap

    Hi Terminator: How's your car running now - have you got the Supercharger to function correctly and are you still running with the 3.91 diff? I fitted this model of diff (E34/M5 LSD) a couple of years ago and absolutely love the improvement to acceleration and cornering. Fuel consumption has hardly been impacted. I drive it spiritedly and with the stock diff got 22MPG (13L/100K). With the 3.91 Diff I get 21MPG (13.5L/100K). A little price to pay for great improvement in performance!.

    Top speed - I chickened out at 140MPH (225Klm/hr) with still more to go. Cornering is much tighter with the LSD, you can really accelerate through them and feel the car hunch down and grip and launching from a standing start is instant acceleration with no loss of grip.

  • Bottom Bolt Torque - Rear Shocks

    I am getting a squeaky noise from the rear suspension. I've replaced the shock-absorber top mounts, fitted top reinforcement plates, replaced all bushes & bearings on the rear suspension, new bushes in the drag links (front and rear), so a bit frustrated. I am suspecting the torque setting on the bottom bolt securing the shock-absorber to the spring pan (wishbone). As the diagram below shows (I'm no CAD user), the relationship between the wishbone and the shock-absorber goes through different angles as the suspension moves. Therefore the shock-absorber must have to pivot around the bottom bolt. However, the shock-absorber bottom mounting is fitted with a solid tube, embedded in rubber (not a bearing). When fitting it into the wishbone arm the tube gets clamped between the two sides of the arm pan, especially if the securing bolt is tightened to the recommended torque. This prevents it from rotating. This seems counter-intuitive to me, surely this must create stress in the bottom shock-absorber mounting as the suspension moves up and down?

  • Changing the center tie rod - help needed

    Interesting. Looking at your photo and the diagram in realoem, I would have thought the tierod is the same whether the car is RHD or LHD. The two ball joints should have the same resistance when new. If you look at part no: 32211138867 (on my car a RHD) then this is fitted to a wide range of variants:

    If I lookup your part number it only shows it listed for one variant:

  • Brembo Caliper Overhaul

    Hi Danilo:
    The front Brembo calipers are aluminium so you shouldn't have any rust (maybe a little oxidation?).

    I fitted the dust covers to the pistons BEFORE I inserted the pistons into the calipers. This ensured the fit around the piston was correct. As the piston slipped into the caliper I pushed the dust cover outer ring around the lip on the caliper. Finally I used a large (40 mm or 42 mm) socket placed over the dust cover then gently used a lever between the socket and the opposing caliper piston to apply downward pressure on the dust cover to ensure it was snugly seated.
