:help

What can I do to prevent my 240 from the front end from skiddin straight when i flip a ***** from a stop?

When I crank the wheel and give it gas the front tires refuse to bite and the front tires just slide. The tires are khumo ecsta's.

Got good grip in the back. Got terrible grip in the front.

Ps. allignment, and camber are perfect

this is sposed to be a good drift car

If I apply the gas, and turn the wheel hard, the front tires are like a sled

My $0.02: Get rid of the kumhos, they're cheap for a reason. Get a nice rear sway bar and some of SPL's subframe collars.

That will be a good start. Then you'll be ready for the shock/spring or coilover upgrade. I'm still looking for a good setup for my driving taste in that department.

It is not the tires. Cause only the front tires are sliding

If you look at my back tires they are bald from doing brake stands, but when I turn the corners the front end is sliding out :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused:

ok, you are a clown.

The Kumho's DO suck, they are quite possibly the sh1ttiest tires I have ever driven on in my life, and like Vkoslak said, they are cheap for a reason.

I can virtually guarantee that they are your #2 problem because your #1 problem is that you have a bad technique. You can't just cut the wheel and expect the car to turn in like a mofo and start a drift because A) you will exceed the front tires grip threshold (especially on 712's that have crappy turn in anyway) 2)it is a noobie mistake and turning the wheel more in the direction you want to go will only produce MORE understeer the more you turn it

If you want to flip a ****** like that, you need to have some decent tires out front and get going slightly, then turn the wheel a bit and clutch kick the ever living crap out of the car. Doing it this way will get the car to start turning, and then when you clutch kick it, it shocks the system and the front wheels bite (since they are already turning) and the rear wheels will lose traction and track around to the front.

Are you trying to help? Cause right now I'm getting mixed signals, I'm really not sure......

Then why aren't my back tires sucking. My back tires are virtually bald from brake stands yet the front end with near new tread is slipping

Okay, 1) you weren't there 2) This is not my first 240, the other one had stock titres, it handled like **** compared to the khumo's but atleast it was balanced. This 240 is very tricky see post # 2 in this thread

divert yourself to above response

I didn't ask how to drift, but thanks.

So far, I like the Kuhmo Ecsta MX's that I am running. According to Tire Rackm they tested very competetively with the BFG KD's and had better braking results and wet traction at much less cost.

As far as the reason for the understeer, it could be several. The important thing it to try and isolate it. But it's hard without the right equipment on a short run where tires don't really show abnormal wear patterns. Maybe mark the sidewall with white shoe polish and try the turn again. If it starts to rub off too far into the sidewall, then you can probably help the problem with some more air pressure. Additional camber will probably make a bigger difference, but then you might see some decline in braking performance if you add too much.

Keep in mind just about any car that is driven too hard into a turn will understeer. With too much speed, the front tires will have a very difficult time turning the car in. If you are trying to get the rear end to kick out from a stop, try either dumping the clutch with the front wheels straight and then add steering once you get the wheels spinning real good. Or, get a slight amount of momentum first, then start the turn-in, then add throttle. You have to get the car to start some amount of rotation first when doing this though, especially if you are fighting against understeer.
