better balance?

anyone tryed to better balance there mr2? 91 is mine cause the wieght percentages is like 45 55 and i want it perfect 50/50 and saw a lead bar of 150 in someones car and was wondering how much wieght i would need to put in the car to make it a 50/50 100? 150? understeer is killer. was also just wondering if anyone else has tryed anything like this let me know laterz

the last thing you ever want to do is add weight. understeer can be combatted with things as little as tire pressure and toe, or entire suspensions.

why would you want 50/50 balance?

Yes, id like to know also, why would you want a 50/50 balance? Any weight transfer of any kind will mess up the 50/50 balance.

y not 50 50? under braking you get 5 more in the front and 5 less the back and under acceleration you get 5 more in the back and 5 less in the front so you stick and break better. its the ideal weight balance for a vehicle y do you think all the high end models are like this?

Adding weight to one end of the car to have it more balanced is horrible idea. Regardless of whatever benefit you want to argue having 50/50 offers, the extra weight to make that happens would really hinder your braking, acceleration and handling.

I've taken 300+ lbs off of my car and a large portion of that was from the driver forward so I suspect my weight balance is even "worse" than 45/55.

That being said, there are plenty of high-end performance cars that are not 50/50 so saying "all" high end cars are 50/50 is not accurate.

Realistically, the net affect of static (Sitting still) weight balance is almost negligible on performance. What really matters is the dynamic weight balance once you start throwing the car around.

mr2envy, where are you getting this data from:
under braking you get 5 more in the front and 5 less the back and under acceleration you get 5 more in the back and 5 less in the front so you stick and break better.

someone who knows more then you just cause you have a nice car and race it dont mean shit

Franz,

The caliber of your response indicates what kind of person you are.
Thanks for being so candid.

I think it is also obvious you have no source for the "data" you offered.

Good luck with you MR2.

as if its not like i can say the same about you

100% agreed. I assure you that I am well aware of what I project and how it reflects the caliber of person I am.

Nice to see all you guys getting along like this so nicely. Must be great to know a 13 year old kid has better manners than mr2envy... :rofl:

manners who attacked who and im not only talking about what kind of person you are but also were you are getting ur data from have you tried it? i came here to discuss and all that happens is ppl saying no that wont work but how would they know if they havnt tryed it? granted you might know alot of things probly more then i but about this topic its seems you have no experiance just personal opinion

no one attacked anyone...

jeff had a valid point, thought not completely accurate. the static weight distribution of your car will have an effect on performance, but more for how you set the car up.


So no, in most cases you don't want to add weight to a car. Unless it is to meet a weight requirement for a racing class. The mk2 mr2 is heavy enough as it is, that it would be silly to try to "balance out the car" by making it heavier. If you want better balance, get rid of the rear metal part of your bumper (if legal in your area).

i agree with dan and hyde. and 'franz', i think a guy who runs 11.1 might have a little more experience then yourself, so it just might be prudent to listen instead of running your mouth.

who attacked who? that who would be you, and nobody else.

personally i'm interested if there's any way to measure dynamic response. outside of torsional rigidity and static distribution, are there any other factors that are measureable?

thanks :)

yea so he runs 11s but whats that have to do with him trying to better balance his car? he doesnt have any experiance in even attempting it

manners who attacked who
You attacked me - Post #6.

You posted something as a FACT.
I asked for clarification on where you got that information and Post #6 is your response? Please explain what that adds to the discussion? :rolleyes:

If you know "someone who knows more" than us, why don't you ask them your question instead of posting on here?

i came here to discuss and all that happens is ppl saying no that wont work but how would they know if they havnt tryed it?
If you asked us if you could get to the 10th floor of a building by jumping out of a 5th floor window and we said no ... would we have to try it to know? :rolleyes:

no one attacked anyone...
I kindly disagree. See Post #6.

Uhm ... That is what I said:

If you want better balance, get rid of the rear metal part of your bumper (if legal in your area).
That is a really bad idea. The heavy metal in the bumper of a MKII is a crucial part of it's crash protection. When you get hit on your bumpers that is what forces the energy around the interior through the structure of the car. I would not touch those bars unless you have a full cage.

yea so he runs 11s but whats that have to do with him trying to better balance his car? he doesnt have any experiance in even attempting it
I agree that running 11s has nothing to do with having a better balance, but it does indicate a certain level of commitment to the car.

I have no experience in balance?
Who are you to say what experience I have?

5 hillclimb wins this year while destroying all 5 records.
3 SCCA autocrosses and 3 wins. 6 drag races and 1 win.

I was undefeated in every event I entered this year that had turns.

Do you really think that would happen with an unbalanced car?

I make sure the "balance" of my car is where it needs to be under dynamic (race) conditions. Bragging that you have a 50/50 weight balanced car means nothing unless you can do something with it. It's like people that put down huge HP numbers on the dyno and the car doesn't run impressive times.

Do you want your car to perform on the scale or the road/track?
If all you are looking for is 50/50 then by all means, adding weight is a swell idea. Power to you. I bet you could get it equal down to the ounce if that what gets you excited.

I'll take a 60/40 car that sets records everywhere it goes over a 50/50 car that fails to perform.

If you asked us if you could get to the 10th floor of a building by jumping out of a 5th floor window and we said no ... would we have to try it to know? :rolleyes:

best af post in the mr2 section ever
mr2 envy- i know a ton of 65-35 fwd cars that would destroy the "high end 50/50 wiehgt sports cars" with equl drivers

jeff says it best, its not the actual weight distribution taht really matters its how you use the weight that is given to you

look at the 350z, 53/47 weight and handles a fuckload better than an s2000 at 50/50, yet it cant drift with anything unless you throw it around and gets lots of understeer(no clutch kick etc...)
