okay my qustion is this, will adding width to the rear end increase launch because the more even weight distribution? as you can see my car has the factory starfish wheels which tuck in on the rear axle compared to the front. its ugly and i feel if i put spacers in, it will improve cornering and probably the launch also. is it most likely gonna help with a little traction and make it easier on my already weakened traclock?

edit: i do run at a nhra sanctioned track so i would preffer if they were track legal. i believe that means i need hubcentric correct?

cuz that would require a lot more money that i wish i had haha and i picked up an 18x10 inch wheel the other day and it weighs like twice the weight of my stock ones. i kinda like having stock looking car cuz it suprises tons of newer cars that cost 4xs the cash

buy some 17x9 cobra r wheels...they are light and you can mount a wider tire on it. plus they flush out nicely in the wheel well...i loved them on my old GT

To improve weight distribution on the rear tires, you want to shift the center of gravity towards the center axis of the tires. Adding wheel spacers will actually do the opposite (force distribution will be towards the inside of the tires). They will also increase rotational mass. So really no point for straight line applications.

what you just said about weight distribution made no sense.. the rotational mass would be additional but because its in a small radius it would be negligable. but if i widened the track it most certainly would level the weight distribution across the rear a little bit

sticking your tires out farther will not help you evenly distribute weight on the rear. If you want to help distribute the weight, put an air bag in the right rear

Haha not sure if you're serious, but I'll humor anyway. The center of gravity of the car along the transverse axis is near the 0 point. Evening the weight distribution along the width of the tires means evenly distributing force or load along the contact patch. When you space out the tires, your force distribution becomes an inverse half bell curve distribution with greatest load towards the inside of the tires. Kind of like this for the passenger side:

Granted, you're going to have this condition no matter what, but when you put spacers that displace the tires positively along the transverse axis (further apart), you make this condition worse. In effect you're shifting the weight distribution or stress distribution along your tire contact patch in the axial direction towards the vehicle neutral point. It's not going to be a noticeable condition, but it certainly won't help you.

im not sure where your getting this info from... perhaps your missunderstanding me. ive been around stock cars a while, and if we run wheels on the car with smaller backspacing and equal with rim, it makes the car wider thus helping the cars weight stay centered through a corner... now i know im going straight, but if i make the tires wider apart, the weight imbalance of my car which is heavy on the drivers side will become a more neutral percentage from the left rear to the right rear without moving weight around in the car. im looking at the picture above and it appears to show the pressure distributing into the ground.. maybe you could clarify that for me? and im not being cocky i just dont understang the image right now
