Is this correct? No, disrespect Jason. I'm just confused because the
solution to the understeer in the stock MR2 suspension that is generally
given is to run the front tires with a bit more pressure than the rear. I
drive an '87 mk1 one and a '93 mk2 and staggering the front to rear tire
pressures with about 3 PSI more in the front seems to work well for me...
Any other opinions out there?
