Is200 Tracking Settings

[kev dood]

A while ago I posted the tracking settings, which I also think Rodders (?) put in the knowledge section.

Anyway, I had also emailed Lexus GB about these and they have come back with some slightly different figure!!

Mine I think originated from a mixture from mainly Javadude and Supracharged IS340. Maybe there are differnent settings per different model years, see email below.

Original settings from Javadude etc etc. are...

FRONT

Caster Min = 5 deg 16', Max = 6 deg 16'

Camber Min = -0 deg 51', Max = 0 deg 9'

Toe Min = -0 deg 6', Max = 0 deg 18'

SAI = 9 deg 16'

REAR

Camber Min = -0 deg 53', Max = 0 deg 7'

Toe Min = 0 deg, Max = 0 deg 24'

Lexus GB sent me this email.

Can anyone shed any light on these, as the front camber settings for example, differ quite a bit!

Also, what is SAI??

[ColinBarber]

They both read the same to me

One gives the maximum/minimum figures and the other gives the mid point and the allowed tolerance each way.

I think the Lexus way of writing it is perfered as those are the figures you should be aiming for when adjusting.

Sorry peeps!

SAI stands for Swivel Axis Inclination , same as KPI which means King Pin Inclination , AFAIK its best described as the angle formed between the vertical axis and a line drawn between the upper and lower balljoints of the wishbones , to the ground .

Are these settings the same on bigger wheels..

Or Lowered suspension..?
