I have no idea. All I know is that there are different angles on the front wheels. :S

Start from parallel or slight toe in and go from there

As above, roughly parellel is a good place to be, tiny (And I do mean TINY) bit of toe out would probably work well, but go to far and it will ruin it.

No, in fact its more likely to cause understeer

Depends on how you drive at the end of the day, and the rest of the front suspension components. I gave you the 'safe' option as a point of reference.

Slight toe in on the front will increase your stability, slight toe out will increase your turn in.

Most racers use the effect of camber thrust on a FWD car to aid turn in, so setting parallel or slight toe in, is the option we prefer for people who dont know what they want.

I use toe out on cold days to scrub the tyres and get heat into them quicker giving you an advantage, and in longer sessions/events use toe in to save the tyre and have a more comfortable day.

I got KONI suspension and springs. Pollybushes in both front and back. Think I'll set the Toe parallell just to see how the car is performing. Tomorrow will be the first time on the track with it so will have to wait n see.

BTW. My my suspension is adjustable. Shall I shoose the hardest set-up or what will work best with the springs? Both springs and shocks were bought from Koni.

Never a good idea to learn on the hardest setting.

If its a dry day find the mid point of each unit by counting the clicks forward and backward and start off by setting the front in the middle and the backs 2 clicks soft of middle.

If the back tries to push on in the corners try things like a softer tyre compound or lower tyre pressures or even disconnecting the rear ARB before going harder.

Just go out and have fun - the learning comes with practice and knowing what you want

Definately agree that starting softish on the suspension is better than starting too hard

Sounds great. Tried the hardest setup on an open road the other day just to see what it was like. And to be honest it did not feel any good. I'll just go for a softer setup from now on until I've learnd to drive the car to the maximum.

What do you mean by disconnecting the rear ARB?

Im driving on brand new Toyo Proxis R888 195/50-15 on a Azev 15*7 wheel. Hopefully it whill be a dry track with about 15-20 degrees airtemp. What tirepressure would you recommend?

Depending on the compound of 888 I'd run the fronts at around 26-28 and the rears 24-26 hot.

So when cold make sure you start off with lower pressures than those as the heat will pump them up.

If you dont know what the ARB is dont worry about it

My tires have a soft compound. But I'll start with your recomendations and see how it feels.

If you mean anti roll bar with ARB I know exactly what it is. Got pollybushes on that little fella. Is'nt it risky to remove the ARB? Allways thought the rear end off the car would be verry lurchy without it.

How can it be risky when the base models dont even have one !

No need to remove anything, just disconnect 1 side as that has the same effect as removing it and it will stop the back end pushing on (creating oversteer) if the suspension set up is too hard.

All trial and error, you wont find a set up your happy with with just one trackday...

Go play.. you have plenty options to go at

Aight... did'nt know they were specik for the RST.

The car worked really good btw. A slight understeering and the brakes need a restoration vs. upgrade. Ill try n disconect the ARB next time to see if I can get rid of the understeering.

Counting the days to next track day.

Glad it went well.

Grippier front tyres will help with understeering too
