Question regarding rear camber?

[pudding]

Good reading.  Coincidentally, I've been experimenting with tyre pressures recently and it doesn't come as much of a surprise that it rides and handles best on the factory pressures written on the petrol flap

Funny that. You'd almost think VW spent a bit of time sussing out what works best

Being more used to 90s VW tyre pressures around 30 psi, I was stunned when I saw the MK5 needs 2.6 bar!!!   It works though

I'd recommend you guys have a read of this, best explanation I could find. Few posts down

I thank you...was for a moment thinking I was wrong all along in my own set up. My suspension travel is quite limited given I have both front and rear H&R ARB's...and still can push a little if accelerating a bit through corners. This is why I have been running 35lbs-R and 37lbs-F for such a long time. Regardless, the OP likely isn't interested much in fine tuning suspension for tracking but thank you for another confirmation of what I had always thought.

After reading a about it, I think this is the best statement, but until today I was convinced that if u lower front pressure you'll decrease understeer: 

Both are correct. Any deviation from optimum pressure will reduce grip on that end, so going either higher or lower from ideal will work. HOWEVER, if you lower the pressure, you are also softening the spring rate which leads to less understeer and now you have two factors working against each other.

One thing is clear tough, i was wrong.

Hey, I was ready to find I had been wrong all along. I read about understeer corrections awhile ago. I found it helps noticeably having the fronts at 2 psi more pressure and the ride is even softer and easier on the seat meter.

I was convinced that if you lower the pressure a bit on the front, you'll get more grip. I will use this info to my advantage next time I'll go to the track.

I would advise you to use negative camber if you want to race. It's the best option for the track.

Indeed, but too much negative camber is crap on public roads.
