Toyota Supra Informational Video

Another Toyota Supra Informational video from the vaults, a Toyota Sales US video back in the launch year of 1993. Still to this day the Supra does not age, for those that watch the video please take note that the supra was probably closer to 4.9 seconds from 0-60mph for the US version. Thanks to Youtube user roliks.

If you know of any Toyota OEM or museum videos for the 2JZ either on Youtube or elsewhere 2JZGarage would love to see them, comment below or contact us directly.

REAS Suspension Diagram, Pictures and Information

Found in the 97.9-02 JDM Toyota Supra (RZ and SZ-R only) was the REAS suspension system – REAS (Relative Absorber System) shock absorber system.

I was lucky enough to have this suspension in my supra before I swapped it out a few years ago for some HKS hypermax coilovers.

I’ve posted a link below with some information on the system and also one of my favourite pictures of the supra, a chassis picture without the shell showing the REAS suspension.

Basically it was to improve ride comfort while still having good flat cornering ability. I’ve also put some pictures of mine when I pulled it out, I still have this available although I’m not sure if they can be re-filled or re-used.

(Translation from Toyota Japan – hence the japanese-english translation wording!)

REAS (Relative Absorber System) for comfortable ride and high handlings stability.
The REAS features an entirely new mechanism that functions not only to achieve a comfortable ride with a relatively small amount of damping force in cases like when both tires hit a gap in the road, but also functions to stabilize the body of the automobile against lateral “rolling” motion by adding a suitable amount of extra damping force and absorb the force acting in the lateral roll direction, as when cornering, when the pattern of depressions and protrusions in the road surface are different on the left and right wheel sides or when subjected to cross winds. Three main points of the REAS structure are as follows

1. The left and right shock absorbers have separate oil chambers with a REAS valve positioned on the connection flow passage.

2A single gas chamber is shared by the left and right.

3. Using the separate actions of hydraulic fluid and gas, a separating piston is activated by the coupled movements from the right and left.

Supra gear/diff ratio and tyre size ratio calculator

This calculator shows the effect of fitting various sized diff and gearboxes to the MKIV supra, it also contains a graphical chart showing the effect of different tyre and wheel sizes and also offsets that effect both fitment to the hub and the change on speed/acceleration. There are two main sheets on the file, Wheel size fitment and gear ratio calculator.

Thanks to Homer off mkivsupra.net owners club for this excel file, If you have any other handy supra or 2jz related calculators feel free to contact us below.
