Been pretty busy around these parts as far as Roxy is concerned. Here is what I did this week.

  • New Struts. OEM, super sport
  • Springs. Eibach, lightly used.
  • Rear sway bar. HK Compitition, adjustble.
  • Replaced boot trim (!)
  • Cleaned throttle body
  • Fresh coat of wax

So far, I can tell the improvement in the overall ride of Roxy. As you already know, she was getting pretty rattly. That is no longer the case. Nice and solid. Rear sway bar has been set to the middle setting on both sides.

Since I’ve barely had the chance to actually drive her at the speed limit, let alone hunt down some curves to do a proper test. So far, I have been able to drive some of the highway interchanges that challenge regular motorists, and I have been able to take them at the speed limit. The suspension is settling in nicely and I expect further testing to happen tomorrow morning.

Notice throttle body cleaning. This was recommended to me by Jerry at Eurotechs to correct a horrible stumble while the A/C was on. Of course he was right and now she only stumbles when the fan turns on, which is SOP for her.

Finally, a fresh coat of wax to top off the week. Next week starts by ordering the missing trim piece from Mr. MINI Parts. Whew. It’s a never ending battle.


Had the chance to test out the new setup on the closest thing Phoenix has to twisties; South Mountain roads to the TV Towers. Not much, but it’s a 30MPH road with the really tight corners, elevation changes and the like. I can report that my MINI definitely handles differently than it did before. Dare I say, better. Turn in is faster, I can actually rotate the rear end slightly and she stays flat. I’m very pleased.

  1. Man, she definitely doesn’t look 265,283 with this new fresh coat of wax. Well done! I’m curious to know how long it takes you to have her this clean?

  2. Thanks Alexandre!

    This is nothing more than a car wash and a coat of wax. Total time is usually less than an hour. Full detail with clay bar and wax, which I do when it cools down, usually only takes me an extra 45 minutes. Still using Meguair’s tech wax too. Love that stuff.

  3. DB, Roxy’s looking good and congrats on the new upgrades!

    I have a similar stumble with my 03’R53. Although mine happens intermittently at cold start and also randomly at running temp (ac on or off). Could it be the fuel pump? What did they do to clean the throttle body, is it something you could do on your own? Thanks

    1. Thanks Ben!

      There are multiple stumbles with the older MINIs. One was endemic to the R53. Mostly a software issue among other things. It was an issue that was mostly corrected via warranty and service visits.

      The other seems to only affect me. When the A/C is on, I get a stumble at idle, mostly when the second fan turns on. It was REALLY bad prior to cleaning the throttle body, happening any time I came to a stop, even causing a stall on occassion. This ‘stumble’ used to really bad when my car was new, but again, it was a software issue. It took about 3 revisions to get right.

      Yours could be the fuel pump. Could be the throttle body. You might just need a tune-up (plugs and wires). Best bet would be to get it checked out, maybe at the dealer to see if there is anything crazy going on.
