Does Your Rolla Under Steer

[Mr Revhead[RL]]

i would think that maybe its extreme body roll rather than on two wheels.

 

you will NOT get on two wheels in the wet unless you hit something. you just will not have the grip needed.

 

 

btw.. to all you using king springs...... theyre are much much better options out there!

a spring is not just a spring

As long as you run good front tyres, its not much of a problem.

In my opinion, if you have two wheels in the air, and two wheels on the road with actual grip, and you're still negotiating the corner, you're about to start using your roof to smash shit, and the world for you is about to become a sad place.

Ok, I was talking to some random customer and this was his idea on my under steer. "I'm a shit driver with a shit car :)" his said that his charger did something like this too. it was coursed by braking into the corner and then accelerating hard.

 

The idea was that the front end dips on braking and on accelerating the front end lifts. This make the front end light for a second and makes the front end slip.

 

 

 

He told me to get a different car, the problem is the engine in the middle of the front wheels. Putting to much weight at the front and making this problem worse. Most well handling cars have the wheels in front of the engine.

TURTLE CRAP!

 

Slow down before the corner and the understeer magically disappears. Once at the apex, gradually feed in the power. Guess what you will be quicker too.

I think your customer needs to get some sort of a clue. Col's right, it's about learning the best way to get a car around a corner. Treat it ugly enough, and any car will understeer. My 25 was fairly unattractive, it wanted to be driven on the throttle, preferably whilst looking out of the side window. No attitude= no turning. Treat it right though, and it was quite quick.

 

I'd like to state here and now, there's no way you're going around corners on two wheels..

 

Tyre's= You get what you pay for. I'd be getting wider ones for a start.

 

Suspension= See above. King's are nice, monroes are fine. Custom are better, koni's/ Bilsteins rock..... keep going up in price and the handling becomes orgasmic.

 

I was told once by a wise man, understeer is when you're looking at what you're about to hit, and oversteer is when you aren't.

what a wak thread...

Dude, if you don't like it, don't read it. No ones forcing you.

curiouser and curiouser (said Alice to the white rabbit).

165 is on the thin side

• fuel efficient? yes ...
  
• good for tootling about town to get the shopping? yes ...
  
• light on the steering for little old ladies reverse parking? yes ...
  
• good if you're into pushing your car a little more than these car's original target audience? no.
  

get some 185's next time you're tyre shopping - that's a good general purpose size.

 

aside:

incidentally 165 65 13 is probably on the small (rolling diameter) side too ... speedo will probably be reading high.

I have 185x65x13 on the AE71which works out a tad under the original rolling diameter

The 25 is harder as I swapped a manual box into an auto without changing the diff - keeping the original speedo drive, I think 185x55x13 was the best fit.

 

From your description, you're just describing characteristicly "ordinary" behaviour.

If you come into a corner too hard, you will understeer - in addition to the lack of steering, the steering wheel will feel light.

As the speed washes off and grip becomes reachievable, the tyres bite and you start steering in the direction they're pointing - the steering gets heavier as the front wheels are now "doing something".

Oversteer may eventuate depending on how hard you accelerate out of the corner, and how much grip you have.

This is fairly standard behaviour - you get rid of the understeer by driving "better" and by modifying your suspension when your skill outstrips it. At this point you start to consider the effect of shocks, tyres, swaybars etc.

 

The only odd thing about your story is the "two wheels" bit - I'd be seriously looking at whether your observers are giving you correct information here. Get someone to drag out a camera phone and get some footage - because two wheels in the scenarios you're describing means something is

• broken
  
• geschtinkered
  
• rotten in the state of Denmark
  

Now .. last point.

you're not doing this testing on public roads are you?

That's an accident just waiting to happen :) - if you're lucky, you'll understeer into a curb and fsck your front end, injuring nothing but your pride. If you're unlucky, you'l loop it and finish up on the wrong side of the road with a prime-mover bearing down on your now stalled car. If you're really unlucky, you'll injure someone else.

I'm with slapper ... public roads are not the place to screw around as there are people around ... find yourself a country block
