Thanks ! Would be nice, otherwise it will be some slow charging.

Yes, it´s a bit strange, I also got a chargingcable in package and it got full 3 phase connection, but it perhaps for the supercharging mode.

Plastic piece where small box supposed to be.

Brian, first of all I`m inspired by Göran Malmberg and his " Zero Car": Dont build in angles and characteristics into a suspension who you have no idea about. Now the car is neutral.
Weightdistrubution in the Elvito is problably not the same as in the Corvette.
The coilovers I´m using has very likely not the same setup as the Corvettes.
I also had a long discussion in a swedish forum with people who is racing with their Super Sevens and all ended up in this setup :)

Okay, but wouldn't it also make sense to not modify geometry which you don't have any idea about? The suspension still has camber change, caster, and kingpin inclination (as it should)... you haven't zeroed those out. Why is anti-dive/anti-squat different?

Right - the Vito is taller and heavier than a Corvette, so it likely needs more anti-dive and anti-squat. Springs are springs, whether they're coiled-up steel wire or flat composite strips; you have presumably increased spring rates to match the higher mass, and have chosen stabilizer bars for the taller vehicle but perhaps more moderate cornering expectations. Did you determine spring rates specifically to work with zero anti-dive and anti-squat?

Does the van with Corvette suspension seem more like a stock Corvette, or more like a racing Lotus Super 7? My guess is that those little cars set up for racing are very stiffly sprung for their mass, and although short are extremely low, so will dive and squat very little even without anti-dive/anti-squat geometry. Is the Elvito racing-stiff... and isn't it a couple of metres tall?

Brian, I have only zeored out anti-squat and anti-dive, all other parameters are the same. Anti-dive and anti-squat lock up the suspension to make the travelling comfortable. If you have race ambitions and wants to brake before a sharp curve, you dont want the suspension to lock up, you still want it to function to get the best grip and keep the speed up.

The Vito will not be heavier than the Corvette, se enclosed document ( in swedish of course). I have been weighted every part I removed from Elvito and weighted every part i put on. Next step will be plastic side windows etc.
Also I lowered the center of gravity, batterypack is under the floor, motor in center of wheels and so on. Only thing which is high is roof. Dont forget Volvo 855 in BTCC back in the days :D

My coilovers is quite stiff, problaby requires testing.

Starting to disamble car for painting. Isolation matt inside torpedo wall 5 kg, removed.

Invalid file....hmm odt document.

No, that's not true at all. Anti-dive and anti-squat produce a vertical component of longitudinal force (upward force at the front in response to braking force; downward force at the rear in response to drive force) to reduce the suspension movement required to handle the load shift required. It doesn't interfere with suspension movement at all. Locking up suspension travel would never help ride comfort, and this isn't really for ride comfort anyway - it is to improve the speed of response.

The degree of anti-dive/anti-squat chosen for a stock street vehicle may not be appropriate in a race applications, due to lower centre of mass and much stiffer springing typical of a race car. You may not need anti-dive/anti-squat, but understanding what you are changing might be a good idea.

The Vito will not be heavier than the Corvette, se enclosed document ( in swedish of course). I have been weighted every part I removed from Elvito and weighted every part i put on. Next step will be plastic side windows etc.

The suspension, wheels, tires, and brakes are the same (and thus at the same height) in the Corvette and Elvito. The transaxle of a Corvette is the same height as the Tesla motor. the Corvette engine is almost as low as the battery of the Elvito. The Vito body - which is a significant part of the vehicle mass - is higher, so the overall result will probably have a higher centre of mass.

Brian, thank you for the lesson ! Must admit I have jumped to conlusion. Built this Super V8 and there I used Corvette suspension and had all the discussions about anti-dive and anti-squat to be or not. Then when I started the Elvito projekt I just transformed the " knowledge" into Elvito suspension setup assuming it was the best. Now I´m a bit confused.

When I wrote lowering the center of gravity I was comparing the original MB Vito not with Corvette.

Ah, that makes a lot more sense! :)

You can just complete the Elvito project to the running state with the geometry as-is. If that works well, celebrate! If it dives and squats more than you want, you can then modify the mounting points.

Sorry, I missed that; yes, the Elvito will definitely have a lower centre of mass than the original Vito. I was comparing to the Corvette, because of the Corvette suspension.

:)Yes C4 suspension dana 44, Ford Mustang GT 2003 4,6 l engine, edis 8 and Megasquirt :D
The mix of brands (Ford engine and ignition, Chevy suspension and final drive, aftermarket engine management) would be good preparation for a typical conversion project, which often mixes a battery from one EV OEM with the motor from another and electronics from someone else. Ironically, the Elvito is essentially all-Tesla for the EV components. :)

Hello, thank you !
Yes, ev conversion is the next step in evolution , built natural aspirated, turbo charged and a car with v8. Now it's time for future

That sounds very nice, Kevin !

I was a bit slow, did not think I had to act that fast.

For the moment I´m upgrading my solarplant with some more solarcells and rearrange some of them for better outcome during all day.
