Post Up a Picture of your Silvia

The front camber seems to actually be a bit too little on the negative side atm, the front end is getting modded for next season with that in mind as well. There's a couple degrees of negative on the rear too and the setup is more understeery than tail happy on corner entry now. But from my and other people's experience the fastest setup is always a bit on the understeer side of balance. Just need to test MUCH more next year, on 2006 the gearbox was always broken between races so haven't really had a chance to work on the setups either.

Ah ok, it looks like zero on the back, but thats probably from the excess on the front.

Do you have any probs under braking? ie lack of grip. I was running 3 degs on the front of my S12, and it was easy to lock the wheels up.

What sort of castor do you run on the front? More or less than standard?

[silveR]

Very stable under braking, and can overbrake even some lighter cars sometimes so can't complain. And shitloads more caster than standard, no way you could drive that thing fast without a good power steering. Mine has a fully electrical one from a Corsa C

So regarding the more castor do you prefer the stability that this provides? I would have thought less castor maybe better as it would make it more agile, although less likely to self centre. How hard was it to implement the electric power steering?

The caster indeed improves the stability and makes the car handle "like I want it to handle". Difficult to explain... Although you can't just point at one detail and rule the way a car handles because of a setup, it's a combination of everything starting from tire pressures and ending with the initial torque of the LSD. If the caster angle is decreased a lot the car becomes like a snake trying to go here and there all the time. Maybe suits someone's way of driving but indeed not mine

About the power steering, not that difficult compared to many other things, but then again the car was built around these parts after it was first completely dismanteled to pieces. One of the best features of the car it is, makes life very easy and features adjustment for steering feel as well.

Should I make a topic about the car, after all this is (or used to be) the photo topic...

Oops didnt realise it was the photo thread
