my manner of driving is a bit strange but SEEMS to be fast... hell i'll post a replay of the car in action
 
Hey, MilleniumHand, welcome to GTP. Sorry to be off-topic here, but would your username be a reference to "He's got a watch with a minute hand, a millenium hand, and an eon hand..."?

If I can make some suggestions on the setup for you:

It sounds like you've made the rear of the car very soft, then had to jack the front ride height way up in order to get the static weight distribution biased towards the front, to help with understeer. I would think this would make the car handle oddly. I would also jack the brake numbers wayyyy up for better braking. Here are my suggestions:

Spring rate front: 8.5
Spring rate rear: 6.5-7
Ride height front: 112
Ride height rear: 112
Shock bound front: 5
Shock bound rear: 4
Shock rebound front: 8
Shock rebound rear: 6-7
Camber angle front: 3.0
Camber angle rear: 1.0
Toe angle front: -0.5
Toe angle rear: +0.5
Stabilizers front: 4
Stabilizers rear: 5

Brakes
Front:10
Rear:10

Those spring rates seem a little low, but start there. If the car seems to wallow, crank them up a little. Typically you want shock bound to be in the 3-5 range, to allow the car to absorb bumps, and shock rebound to be in the 6-9 range, to keep the tires planted well. Almost always, the B/R values should be higher for the rear dampers than the front, to encourage rotation (oversteer).

Camber is your friend. Adding camber really helps to keep the tires flat on the road as the car leans, which maximizes grip. I usually start with 2.5-3 degrees in front so the front end grips all the way through the turns, and start at 1.0 or so for the rear. If the car understeers, decrease the rear camber a little and increase the front. Vice versa if the car oversteers.

Stabilizers I usually start set to 4/4, which controls body roll without costing too much traction. If the car understeers, bump the rear up a notch or two. If it still understeers, bump the front down a notch.

Hope this helps!
 
What do you mean, "lose grip during braking"? Is the car understeering - not rotating enough as you enter a corner? If so, try the ones I have listed. It should make a big difference in the handling.

The settings you have are very different from the way I would set the car up. You say you have a 'bit strange' driving style. Could you describe it?

The line I quoted is from the song Particle Man by They Might Be Giants. That's why I asked.
 
I use a pseudo-drift style

I turn and break while the body roll from the turn is still in place causing the rear tires to break free from the ground while leaving the front tires with traction.

under acceleration i prefer having a sizeable amount of grip while being able to powerslide the car with ease for a minute amount of time.


for my racing style, understeer is good.
 
Well traction in turning relies a lot on the LSD. Set the decel and accel low so that the traction breaks entering and if not enough sliding rotation is present the lower accel lets the tires slip when feathering the gas in lower gears. Then upshift to gain traction, then back down to get your revs back up...assuming you're using a manual transmission.
 
I took some of you two's suggestions into account
I cut .4 secs off my previous lap time that brings my lap time with it down to 1'06.647


Spring rate front: 7.5
Spring rate rear: 9.0
Ride height front: 118
Ride height rear: 118
Shock bound front: 8
Shock bound rear: 5
Shock rebound front: 7
Shock rebound rear: 4
Camber angle front: 0.6
Camber angle rear: 1.0
Toe angle front: 0.0
Toe angle rear: 1.0
Stabilizers front: 1
Stabilizers rear: 4

limited slip

Initial torque: 15
Acceleration: 30
Deceleration: 10

the rest the same as last time
 
Why are your cambers so low? Up the front to between 2.5-3 and the rear between 1.2-1.7...see what that does for you.
