    So I assume, if I ever take my Mirage (European Spacestar) to the UK after the warranty is gone, I would have to search for a UK gearbox, to get lower RPMS at high speed?
    I would love to do that !!

    What if you replaced the USDM 3rd gear(1.3) with the UKDM 4th gear(1.047), as well as swapping our 4.55 for their 3.5 final drive? I think this is the most economical transmission possible, the next step would be the tallest/skinniest wheels you could fit.

    Let's consider the other end of the spectrum. What is the quickest gearing we could have? It looks like the UKDM 4th and 5th would actually be 'faster' gears than the US versions?

    Added to post #1: photos of the part number labels from the taller-geared Euro spec transmission and a North American transmission.

    I'm switching to 185-60-15 tires soon. These will drop my 5th gear RPMs at 60mph to around 2800 (it would usually be 3000 with Enasaves). Not a huge difference, but I'm moving in the right direction and my car sees plenty of freeway cruising.

    Have to consider the increased aero drag from wider tires though! (Well documented.) Also, higher ride height = more drag. It's a balancing game. An air dam or tire deflectors could help there.

    All that said, I will be trying taller tires as well, once the snow is gone (soon).

    Have you considered 175 something whatever size they are that dirk and I run? They are a little taller and not as wide as a 185. I know the 185 60's I use at work are noticeably heavier than the stockers. But even scotty probably knows that.
    I did get noticeably better mileage with the stock tires during the short time I ran them.

    I think a taller tire might be more beneficial on a 5 speed over a cvt.

    I don't expect to be taken seriously until I start my youtube channel.

    Top Fuel can't use the 175/65r14 (23" outside diameter) tires that Dirk uses, because he switched to 15" rims.

    Even Scotty would have know that!

    I do think 175/65r14 (23") & 185/55r15 (23") tires would have been perfect factory size Mirage tires for the States, because those are two popular tire sizes with many choices to pick from. I don't blame people for going to those sizes for better choices/options.

    As far as snow tires go, 165/65r14 (22.4") is not a bad snow tire size for a small car. The last thing I want is a wider snow tire on the roads that I travel on, but that is not the discussion here. If the option existed, I would pick a 155 wide tire for snow. I would have even explored 155 wide tires with a 13" rims, but we all know 13" rims don't work on 2017+ Mirages.

    I would be a bit skeptical of using oversized tires on a small economy, especially with a CVT transmission. Even with the manual, I would be a bit concerned (not as overly concerned).

    I look forward to your experiment. My hypothesis would be that you aren't going to be overly impressed with the larger tires. A hypothesis is just an educated guess, however. Proving a hypothesis wrong is just as good as proving it right sometimes. I hope your new tires do what you want them to do! I look forward to hearing about the outcome!
