why does the left front lift higher then right side on launch?

**greatwhiteZ28** · 07-27-2007, 08:28 PM

someone told me before but still dont really know why

**mrr23** · 07-28-2007, 05:38 PM

the direction of the motor when it moves is from driver's side to passenger side. meaning the motor is lifting up on the driver's side of the car from the rotation of the crankshaft.

i thought the passenger wheel picks up higher?

**greatwhiteZ28** · 07-29-2007, 02:58 PM

Not that I know of.

Ever see an older semi take off from a light with a heavy load?? Lots of times the drivers side front wheel pulls off the ground

would that be somethign to do with the diff??

The differencial has alot to do with it to. The passenger side is the side that recieves power first untill the limited slip kicks in. engine torque does it as well though. Plus the way the panhard bar is attached, when you launch the car not only squats down but the rear squats to the right (passenger) as well there for making the driver side want to lift more.

It's a combination of things but all these do have an affect.

soo some will lift on pass and some on drv. cool,

not sure if this is true or not but kinda beleive this guy. this one TAwith like 600+ HP said that when doing some passes at the races with t tops off that it twisted or soemthing. soo no i guess the t tops are lil harder to put on or line up casue he twisted it......

**greatwhiteZ28** · 08-10-2007, 05:53 PM

all i know is that when i talked to him on the street the tops were on soo either its bull or there supper tight

**thecorrectformula** · 08-10-2007, 06:09 PM

Most cars will lift more on the driver side like your asking because of the diff. and engine.

Anyone pushing 600+HP who doesn't have SFC's and a full list of other chassis and suspension upgrades is probably an idiot. If he twisted the chassis badly enough that he couldn't get the T-tops back on, he's probably screwed.

**greatwhiteZ28** · 08-10-2007, 08:00 PM

not sure if he had all that done, but from the looks of everything i think he might of.. maybe he was just low balling the # of hp for the street races>>> i dont know

**greatwhiteZ28** · 08-10-2007, 08:01 PM

i know thats not super common of stuff not fitting but have you ever heard of that?

**BLKCLOUD** · 08-11-2007, 02:07 AM

The driver's side tire will always be the tire trying to lift the most - unless you have an engine that runs backwards. Around here, who knows.

Minor suspension work can fix the twist.

FYI, first image is slicks, second is DRs.

**greatwhiteZ28** · 08-12-2007, 05:02 PM

would tires help this

**greatwhiteZ28** · 08-12-2007, 05:04 PM

and when your talking minor suspension work would that be add a stiffer spring in the right rear, like on the eibach drag launch kit??

when is the drag launch kit really help out these car for racing. would it help out on a 12 sec car or is it more suited for the 10-11;s

**BULLET_WS6** · 08-12-2007, 05:06 PM

torque my friend.. nothings gonna fix it cept for a more rigid frame cuz its just frame twisting... tires wont effect other than the fact u get more grip an get more air...

**greatwhiteZ28** · 08-12-2007, 05:08 PM

kinda knew that just the pics and post made it seem like the dr s helped out .

Sorry for any confusion. I was trying to show the difference between a hard launch and virtually no suspension vs a hard launch with some modest, but very useful suspensino mods.

To cure the twist, you need to stiffen the passenger side more than the driver's side. That can be done with an anti-roll bar, or it can be done with air bags, which is what I went with. I ran 20-25 psi on the passenger side spring, ~5 psi on the other. Combined with cheap, non-adjustable control arms, and a set of adjustable shocks (once again, stiffer on the passenger side) the result was what you see in the second pic - a much cleaner, straighter launch without breaking the bank. Very easy to adjust, too.
