daniel .. depend on ur own driving style, whether u prefer understeer or oversteer ?
1) when u got a sport suspension (PSS9) with normal street compound tyres, ur car chracteristic wil b more to understeer ...
Braking point n handling wil play the roles ... if u brake too late even though ur car bodyroll not much .. but the front tyres loss traction n wil force u to run wide n out of ur racing line. so u must understand where is ur car Max n Min braking point, even u brake earlier dun mean ur laptimes wil b slow...
u brake earlier , u also can accelerate earlier in the middle of the apex . this type of driving style wil b more comfortable n easy to handle.
2) when u got a set of racing compound slick / semi slick tyres with standard suspension ... ur car characteristic wil b more to oversteering ...
everytime u brakes , ur car bodyroll wil b huge n like a snake ...even u got a set of racing compound tyres , the G-force wil kick u out of ur racing line, :nyehehe: then u wil fight like hell to keep the car on the track ...
this will also endanger others car behind u .. coz ppl dun know where exactly ur car wil go ...
for me i wil go for sport suspension coz the characteristic for UDM (rear wheel drive) already is Oversteer, if ur setting stil go for oversteer .. then track wil not suitable .. go to the carpark n do some drifting ..
just my 2 cents ... soli if i got mentioned anythings wrong
