Neg. camber machined rear spacers???

[Tamago]

the reason that camber spacers were never made is because:

under compression, camber on a trailing arm axle turns into toe-in.. so. if i were to develop camber shims for the stock-height yaris, and they're installed on a lowered yaris, a good portion of my camber would now turn into toe-in (the car is already toe-in from the factory). so, now your tires truly ARE gonna get shredded..

likewise, if i designed the camber spacers for a lowered yaris, and someone with a stock-height yaris installed them on their car, a lot of that camber would now be toe-out.. which is not a safe thing for the average car/average driver (toe out makes you spin out)..

this is why we (Penguin Garage) never developed camber spacers. as far as the kiwi who knocked off our design, i cannot answer as to why he never made any...
