Hahaha yeah, I had to trailer the car home when I bought it. I have a little experience with that, shouldn't be too much trouble to get it down to Tabcat Bridge. Be pretty funny to be running silent and creep up on people. It really just needs some better tires but its down fall will be the brakes. They will die a fiery quick death, it is a heavy little car.
That said, I've only managed to put in the control module for the VSP so it's all quiet running now. No more forward motion sound, no more backup beeper. I decided not to put the coils on until I get wheels/tires and do it all at once. That way I can get the alignment dialed in for the wheels I want to run. Most likely 19's....
The front can run camber bolts which is nice and easy. The rears are a pain. Torsion bar doesn't allow for any type of control arm or slider for adjustment. Have to slip an angled shim ring in behind the rear hub after unbolting the entire assembly. Very limited options for camber adjustment. I think -1 might be the most available unless I try and stack 2 shims but I think thats a bad idea. I know the brake might not be centered right and more than a few Prius dudes had issues with rear shim rings and brake spacing. Oh well. Hopefully just get it low enough and be able to run close to 0 or -0.5 with a 0 toe and I'll be happy. Try and run about the same up front.
Plenty of fender lip for roll/shave/pull if needed for clearance but I'm not going too aggressive on the fitment. Probably 19x8.5 +35 and run 225/40/19 tires or 225/35/19. I may drop to 18"s but I don't really want to. It's a few hundred dollar difference but eh, I think with the large wheel arches and "big" side profile it needs a big wheel to fill them. I don't want to go any wider than 225 due to rolling resistance and just plain not needing that much tire but I also don't want to stretch a tire very much. 225 on a 9" is my comfort limit. I don't want to try a 225 on a 9.5 with a short sidewall like a 35 series.

saw some battery news and thought about your leaf - 200 miles of range on 6 minutes of charging from a new lithium battery. If this is true and they bring it to market, it'd be a pretty big game changer for electric cars.
Toshiba Develops Next-Generation Lithium-ion Battery with New Anode Material
・New battery realizes driving range of electric vehicles boosted to 320km on 6-minute, ultra-rapid recharge, triple that possible with current lithium-ion battery.
・New anode material, titanium niobium oxide achieves double the capacity of the anode of current lithium-ion batteries.
TOKYO—Toshiba Corporation (TOKYO: 6502), an industry leader in lithium-ion battery technology, today announced the development of its next-generation SCiBTM, which uses a new material to double the capacity of the battery anode. The new battery offers high- energy density and the ultra-rapid recharging required for automotive applications, and will give a compact electric vehicle (EV) with a drive range of 320km* after only six minutes of ultra-rapid recharging—three times the distance possible with current lithium-ion batteries.
Toshiba launched the SCiBTM as a safe, long-life, fast charging lithium-ion battery in 2008. Since then, the company has constantly refined the technology and improved real-world performance. For its next-generation SCiBTM, Toshiba has developed a titanium niobium oxide anode material that has double the lithium storage capacity by volume of the graphite-based anodes generally used in lithium-ion batteries.
The new battery also offers high energy density and ultra-rapid recharging characteristics, and its titanium niobium oxide anode is much less likely to experience lithium metal deposition during ultra-rapid recharging or recharging in cold conditions—a cause of battery degradation and internal short circuiting.
Toshiba’s current SCiBTM employs a lithium titanium oxide anode, and is known for excellent operating characteristics in respect of safety, long life and rapid charging. It has found wide use in vehicles and industrial and infrastructure applications, including automobiles, buses, railroad cars, elevators and power plants. The high energy density of the battery, and its rapid recharging, have made important contributions to enhancing the convenience and promoting the spread of EV.
Building on this heritage, Toshiba has developed a proprietary method for synthesizing and disarranging crystals of titanium niobium oxide and storing lithium ions more efficiently in the crystal structure. The anode of the next-generation SCiBTM realized through this approach has double times the capacity of the anode of current lithium-ion batteries.
“We are very excited by the potential of the new titanium niobium oxide anode and the next-generation SCiBTM,” said Dr. Osamu Hori, Director of Corporate Research & Development Center at Toshiba Corporation. “Rather than an incremental improvement, this is a game changing advance that will make a significant difference to the range and performance of EV. We will continue to improve the battery’s performance and aim to put the next-generation SCiBTM into practical application in fiscal year 2019.”
Rigorous testing of a 50Ah prototype of the new battery has confirmed that it retains the long life cycle, low-temperature operation, excellent safety and rapid recharging characteristics of the current SCiBTM. The energy density by volume of battery is twice that of the current SCiBTM. The next-generation SCiBTMmaintains over 90% of its initial capacity after being put through 5,000 charge/discharge cycles, and ultra-rapid recharging can be done in cold conditions, with temperatures as low as minus 10°C, in only ten minutes.
Toshiba will continue to develop higher energy density batteries that extend the range of EVs and support ultra-rapid recharging, and aims to commercialize the next-generation SCiBTM in fiscal year 2019.
Part of the research work on the next-generation SCiBTM was subsidized by Japan’s New Energy and Industrial Technology Development Organization (NEDO).
