Electric Classic Cars has a YouTube video "Classic Mini bolt-in kit". 


I think it weighs too much for everyday driving and who has a smooth airport runway to go back and forth. 

Those are the guys we got our kit from. On paper ours has the same 33kw capacity, but we've found that realistically you cant actually use the last couple of watts as it just isn't enough juice to propel the car at any speed. Technically there's 2-3 kw left, but the voltage dips below the inverter's cutoff threshold when you do anything more than a couple mph. As far as the weight goes I'm not sure how they've kept theirs under 1600lbs. Theirs being a Mk1 helps a little, but the rear battery pack alone weighs 265lbs, and I'd estimate the under-seat pack at 40-50, meaning they started with a car that weighed less than 1300lbs? The weight of the tesla motor plus the front battery pack is very very close to the weight of a bare a series. During its previous restoration before we got ahold of this car someone did take the liberty of bathing every square inch of the interior with sound deadening coating and then applied dynamat on top of that, so there are easily a few unnecessary pounds on this shell. A while back we had an an automatic Rover SPi in the shop that tipped our scale at 1710, so I dont feel too awful broken up about this car coming in at 1800. 

This one https://www.youtube.com/watch?v=fKWe1R1bWOM appears to be the same set up but with the 33kw set up. But they say it's about 700kgs which would be around 1530lbs, and theirs has a roll cage. Why is yours over 1800lbs?
Hopefully you've improved your buying process from 2 years ago when I tried to purchase that blue shell that you were advertising, after spending 2 months trying to buy it for the advertising price and get the car details for my broker. Wasn't too impressed. 

This is definitely a big concern for us as well, and a big reason that we are using standard suspension components rather than designing our own. So far we're happy with the handling, though we havent pushed it particularly hard through corners. The extra weight in the rear is clearly an extra burden on the rear suspension cones, and I think we'll try switching them out for coils to see what we get. Haven't ever been happy with coil-over suspension because of noise and lack of travel, and the idea of the weight of the vehicle now relying on the rear shock mounts has never sat well with me.  Currently running a front anti-roll bar, and may try a rear as well. With this conversion the goal has been to make every aspect "at least as good as" the standard car. We've often felt that high performance minis sacrifice some comfort or handling in the name of speed. "at least as good as" seems like a super easy target but having driven a couple of virtually new MPi cars, an ERA turbo, and some other well sorted a-series cars, I know they're hard to beat in terms of enjoyment. We've very easily hit the speed and comfort targets, so now its down to dialing in the handling and trying to make the car feel lighter than it actually is. 

We (and the car) are in Buellton California. I couldn't find a whole lot of info on the Moment Motors conversion, but it appears to use a minitec (or similar) front subframe, honda transmission, and hyper9 motor. couldn't find any kWh or range specs, thought I'd love to know some more about it.  

I like the idea of the electric motor, but my concern is the weight. With over 1800 lbs dry, I think you are at the upper range of weight capacity of the mini. You have added 25 - 40% more weight to a very light car. Put two average size people, maybe a couple of kids in the back seat and you've certainly disrupted the mini handling characteristics. Ok take out the extra passengers and strap in your dog, that's still 200 lbs added to 1800 and you are still 33% over the base weight of 1433 lb mini. Besides the look of the mini, the second benefit of the mini is the handling. Can the suspension components work in concert with added weight? You have to believe that I'm from the school of Colin Chapman.

Where is the car located? This price range put it in the same ballpark as a Moment Motors conversion.

This one weighs just over 1800lbs. Weight distribution is close to 55/45. Its C8 corvette money and we don't hesitate to point that out to prospective buyers. 

How much does it weigh? Pretty steep competition for that kinda money.

Hey all. I work at Gildred Racing in CA, and we've recently completed our first Tesla conversion using a kit developed by Electric Classic Cars in the U.K. We started off with a cosmetically *decent* 1971 MKIII with a blown up 998 and stripped it down to bare bones before proceeding with the conversion. Posting this here now to field any and all questions, comments, concerns, and criticisms, whatever they may be.  ECC assembles their own battery packs using LG or CALB batteries as they have a greater power density for their size than a tesla pack. The conversion requires very few modifications to the body shell and does not require the removal of the inner fenders or any modifications to the tunnel or trunk floor. It uses a modified standard front subframe, so all of the suspension and therefore suspension geometry is standard and compatible with existing aftermarket upgraded parts. It uses a Tesla SDU (small drive unit) rated at approximately 294HP and 243ft/lb and 3 battery packs linked in series, good for 348V and 29kWh of power. The next couple of conversion kits we will be receiving will have a slightly higher kWh rating, hopefully around 34. When driven sensibly its good for about 110 miles of range on a charge. if driven around town at the pace of a mini 850 you could probably expect 150 or more. As it sits it has a greater range than a new Citroen Ami, electric Smart ForTwo, Mazda MX-30, or the new 2022 electric Mini. This car is equipped with a Quaife ATB limited slip diff, and 2 drive modes that can be configured to the users liking. Currently they are "normal" and "sport" but could easily be changed to be even more economical. Regenerative braking is also configurable and can be dialed up high enough to allow for 1 pedal driving if preferred. We dont yet have an official 0-60 number but it should be somewhere around 5 seconds on street tires. Top speed is also unknown, but is estimated around 110 on 10" wheels. The cost for a conversion like this is, in short, a lot. This car is currently for sale with a 6 figure asking price. As we continue to work along side ECC to make this conversion more streamlined we hope to see the cost to come down as well. We'll be taking delivery of at least 4 more conversion kits early next year which have already been spoken for. This kit is not available to the public, and will not be sold to do-it-yourself installers.
