Re: Driving Techniques - How to stop the front end from 'pushing'	Mon, 07 June 2004 02:51

If your having to tighten the apex in the corner and your understeering theres 2 things wrong in terms of your style.. firstly you havent been looking up and ahead through the corner and secondly, because of the first error youve misjudged the apex. EDIT: also forgot to add here if your brakeing thru the corner youve left it too late, you need to achieve nearly 90% of your brakeing in a straight line before you turn the wheel in to the corner.. the other 10% is for control at entry, you should be acclerating before you hit the apex. now that youve discovered your driving flaw lets look at the mechanics of it. Forget about improving the suspension for a sec... if youve come in hot or are having to tighten and you are understeeringthen you can try these few things.. remeber to try this on a safe track first that way theres no.. mishaps ... in a FWD floor the thing and hang on, it may break more traction on the inside wheel depending on the point in the torque range your sitting in or the quality of your suspension, but a FWD will pull out of understeer almost every time. In RWD once the front is letting go the worst thing you can do (insert IMHO here) is to brake... unless you are going so fast your going to hit something anyway and you want to try and scrub off the speed before impact. Braking throws the weight back over the front which is allready forceing the tyres to an irregular shape at the contact patch and to loose traction.. the added weight shift spreads the contact patch wider and as we all know.. wider tyres when sliding, especially in the wet offer less traction than a narrow contact patch due to weight dispersion. In my experience a couple of things that seem to work are this... if you have good throttle control over your vehicle and are confident in your ability, then you can feather the throttle to make the weight transfer foward and back, you do this by keeping the car neutral in terms of accel and also using the throttle to make the car slow slightly by closing right off then a slight blip back on. imagine it as ABS without the brakes, it works better on loose surfaces than hard as the rear tends to kick sideways as well to help counter the understeer. Ive found it can also help to turn the steering wheel a little harder into the corner on the back off to throw the ass out more another way is to use full throttle, wait till the car is at a point so far understeering into the corner that you know if you dump a load of horsepower the car will end up in a straight line pointing in the direction you want to travel, keep the pedal well down until it starts to grip then ease off, this is great for tarmac and is close to what the "drift" guys do in japan. in a smaller powered vehicle like a sprinter etc you will need to dump on the throttle, then quickly pop the clutch to make the rears spin up. warning! on the road where theres all sorts of solid objects around you, this isnt a guide for the uninitiated!!! the final way to combat it is to throw the car in to a negative stance, this feels horrible,unnatural, and is hard to make yourself do. as it starts to slide up front engage the clutch and keep it there until the car regains composure this can seem like forever, do not touch the brakes or engage the gear during any of this time, and the G forces feel very unnatural.. but it does work, not really usefull for any performance application but it does make the car regain itself. ok beyond all this the main issue is you probhably havent set the car up correctly .. and i cant be bothered writing another thousand words right now Warning!!: the words and descriptions used in this scenario are not neccesarily the opinion of the toymods board, it is the authors intention that this advice be used on roads which are not for general public use [Updated on: Mon, 07 June 2004 09:28] [Report message to a moderator]
