What tyre pressures are you running on your BEC's?
My car is 453kg and I am currently running on 18ps front adn 20 rears. Weight distribution is 52/48...corner weighted
is it right?
Sounds about right but it depends on how the car is handling- tyre pressures can be used to modify the handling to an extent (easier than adjusting
suspension).
I run 20 back and front personally cos it's easy to remember and the tyres seem to be wearing nice and evenly
Also depends what tyres you are running. A normal road tyre will need more pressure as they have softer sidewalls but a motorsport tyre (R888, A048R etc) have stiffer sidewalls. On a BEC with R888 I would say 20PSI was on the high side. 17-18 would be a better bet.
I was using about 16 psi, and that felt ok
there was a thread on here a while back with some info from toyo re there r888 tyre. they suggested much more preassure but i always ran 20 front and back!
i run 13psi frnt and rear weighs in about 550 plus me
A048's rear R888 front
try it lower it grips really well
13 psi is way too low for a 048, especially on a 13" rim. Are you sure you are not compensating for too hard suspension?
Yoko technicians have said that the 048's give their best grip when running at 22psi hot - on my race car I would typically start around 16/17
psi cold. On a standard car on the road you would probably add a little more as you (hopefully) won't be going banzai on the road.
For standard road tyres 18-20psi would be the norm.

I run 16psi but that is on soft hilclimb-compound slicks (13 inch) - works for what I need!
