Fast Road Geometry Settings

[mwmackenzie]

Hi Folks,

I have my car booked in for a 4 wheel geo tomorrow morning and looking for some settings to have it set up to.

I've had a route about on here and another MR2 forum and not found anything conclusive on this. I can find race car setting and folk saying it's a personal thing, which I know it is but I'm just looking for a starting point which doesn't have so much understeer dialed into it, just a nice balance.. Car is a na rev5, lowered 40mm and used primarily as a commuter with weekend jaunts down the back roads and it'll be very, very lucky to see a track as it's just so slow lol. That said, trackdays are more about exploring the limits, staying within them and enjoying what you have for what it is, so on that basis it may get an outting yet lol...

Currently inclined to go with stock settings but a tad less understeer might be nice;)

Thanks in advance

Stock settings are the way to go for road use.
You should not have understeer, what has been done to the car?

Hi mate,

These settings above are certainly a good start, I hope that helps.

Cheers, Michael.

If you use the Hunter equipment there are three options, the last option is the one that I used and is for a Rev 1 Jap Turbo import.

You can also check your VIN against the system.

Thanks guys, car is just lowered on standard shocks and now on 17's so adjustment is very limited, I think stock may well be the way to go to start, going for a run tomorrow so will see where I want/need to go from there

Thanks!

Thanks for that I gave them these figures and they were somewhere closeish lol

Front

toe NS 0.04 OS 0.03 total 0.07

Front Camber
NS-1.08 OS-0.43

( Not adjustable but I can get hold of camber bolts, do you think these figure need addressing as they're 0.5 degree different side to side?

Rear
Toe NS 0.1 OS 0.14 Total 0.24

Camber
NS -1.41 OS -1.55

How do these figs look to you, feels i bit better than before but it was a bit out
To Start I had same camber as after but ..

Front

Toe OS 0.00 NS -0.06( Out of recomended range )

Rear

Toe OS +0.19 ( Out of recomended range ) NS+ 0.43 ( Out of recomended range)


Any input welcome and apreciated

caster?

After fitting Polly bushes mine was reset from 3.56 to 2.39 on each side. tolerance range is 2.15 to 3.15

What is your thrust angle?
Mine was -0.01 and drives as straight as a dye on & off boost.

[mwmackenzie]

Caster is not adjustable on the rev 5 or is it? It was OK anyhow at

NS 3.47 OS 3.24. Both Green and within the tollerances they had listed of
2.28-3.58

Thrust angle went from -0.12 to -0.02 I/m not sure what this should be as it's grey on the sheet and no arrow showing within tollerances and no tollerances listed.

Thanks for looking at the figures and feedback
