Squatting the rear of the car

I had noticed, i will post some pics later, but i actually saw that my car squats so hard dumping the clutch at 6000 when i was trying to launch really hard, even though it bogged, but the TQ arm actually contacted the body and split the sheet metal, anyone ever have this happen before?

I'd inspect or replace your tranny mount first.

that split isn't above the tranny, it's under the backseat by the rear center section.

LCARB time

Re: Squatting the rear of the car

the lcarb's aren't reserved just for cars at a lowered ride height. they add anti-squat, which avoids carnage such as you're experiencing.

Re: Squatting the rear of the car

Little bit of LCARB and some work to the shocks/springs could help that as long as the tires continue to bite. Abit stiffer rear shocks can help control the body squat and transfer more of that energy to the tires/rear

Ok, i thought they were for lowered cars. How does it effect the car from squatting? I was just thinking a stiffer shock.

No biggie, my car is just a beater, so i actually thought it was cool that my car does hook that hard at the track, but it isnt good.

Yea, a stiffer shock is the first on the list but i dont know what kind that are decent but not expensive.



So, assuming removing the front WS6 sway bar will not help this?

Re: Squatting the rear of the car

remove the front sway bar and weld on some relocation brackets and you'll be good to go, put them in the middle hole and hit it.

Stiffer shocks are probably not needed until you do the above first so save your pennies. Or buy some air lift bags before the shocks.

My .02 of course, so take it for what you will.

Re: Squatting the rear of the car

Yep try shocks after you try LCARB's and sway bar. Should beable to launch decent with sway bar, but doesnt hurt to lose it.

Re: Squatting the rear of the car

It rolls out hard as hell, but bogs, i am sure it needs jet extensions, as hard as the front end does come up, the fuel has to be sloshing to the back so hard that the rear metering blocks are just not getting any fuel to the jet openings.

Thanks for the advice guys, LCA relocators are on the to do ASAP list.

But, i just scored a 1000$ wad from my dad for an early Christmas deal, so a set of ported heads are coming WAY sooner than i planned, LOL.

Got some more mustang **** to whoop on.

Re: Squatting the rear of the car

My car did the same thing but mine did not put hole in the floor pan just rubbed it. I was running stock torque arm with solid trans mount. I think it was the whole arm flexed and the car squatting. I was running low 12's with the stall converter and slicks. I would also suggest the LCA relocation and a after market arm. The LCA's help a lot

Re: Squatting the rear of the car

how about a $350 driveshaft first? then $100 on relocation brakets, then worry about it ?

Re: Squatting the rear of the car

i am doubtful its squatting that badly. probably damage from hitting a dip in the road. my gta has hit the floorpan before also, but its not from launching. im assuming it happened while trailering the car somewhere.

Re: Squatting the rear of the car

I bet it is squatting that bad. Mine would hit the bump stops on a footbrake launch before putting the brackets in. After putting them in, no more squatting and the wheel to fender gap actually stays the same or gets a little bit bigger.

I think the relocation brackets will do the trick, as thinking about it all night while at work, it just makes since.

Local shop is going to make me one, should be cheaper than that too.

Launching at 6000 i think did it, because it was not there when i removed the interior carpet, then i went to the track, then it was there, not dis or anything like that, my exhaust would let me know otherwise by scraping REALLY bad.

Looks way better, thanks for the pics.

Thanks for all the input fellas, i really never knew it would be something to use on a stock ride height car, so as soon as i can, i will be getting a set. I got the cash for heads right now, so that is the primary focus as well as the drive shaft and LCARBs. Otherwise, removing the front sway bar and the front impact bar are happening really soon, i have to see how much it will help on the street, i think a couple bags of concrete for the hatch to see if i can really launch on a couple mustang guys locally talking ****. They jump out and i have to reel them in.

Re: Squatting the rear of the car

evilcartman, what was the 60' on those shots?

my 4th gen would 1.53 off a 6k dump and never did anything close to that. lowered with eibach pro springs, stock shocks, no relocation brackets, but it did have a fairly short body mounted torque arm. front swaybar was still on there.

The short/body mount arms increase the "hit" on their own.

if its the jegs/alston style arm, those give a ton of A/S% themselves, usually making the LCARBs not needed

i know, but the lca's are quite a bit "negative" due to it being lowered. it must add a boatload of a/s. what arm was evilcartman running in the pic?

Re: Squatting the rear of the car

Don't remember the 60' times but probably 1.80 something in the first shot and high 1.60 to low 1.70's in the second shot. I'm running a Spohn torque arm mounted to the crossmember. The shorty arms really change things up. Guy I used to help out was running one on his 4th gen bird launching at 7000 and he'd get a ton of fender/wheel separation. He had to raise the lower shock mount so it wouldn't extend to the end and unload the tires.

Re: Squatting the rear of the car

Mine hooks pretty hard, 1.4-60'. The torque arm at the diff hit the tunnel so many times it finally ripped thru. I notched the tunnel and welded it back up. It almost looks like its supposed to be like that.

Re: Squatting the rear of the car

why not put some relocation brackets on that thing? i bet you get well into the 1.3x range with them when you get rid of all of that squatting

What torque arm are you using?

I put a much bigger hole in the floor when my BMR adjusting link broke (not its fault).

I have LCARB's on both cars. I was running the stick car in the upper hole when the adjuster broke. When I get it sorted out, I'm going to try the middle hole, because it was still slipping pretty good off the line, whether 4000 RPM or 5500 RPM launch.

Re: Squatting the rear of the car

It is the pic i guess, i should remove them for weight reduction, LOL.


Was a great night, i got my 7.2 at 97 MPH, i wanted a 7.1, but they kicked me for no fire suit, biitches. Was on a 1.6 60 foot, so i wanted to drop to 10 PSI and hit it again, but they said my leather jacket was not good enough, LOL.

Nothing broke or made funny noises, so i dont know if i could be happier picking up 3 MPH and a few tenths from a carb adjustment and swaybar removal.

The LCARBs seem to be working, here is the video, i got sideways launching and had to just ride it out, it just didnt want to hook like usual on 12 PSI, i usually run 10, but wanted to step down and didnt get to make a 10 PSI run, which would have got me a 1.5 60 because i would have launched at 6K.

So, 6.9x is the near future goal when the 243 heads go on, i am sure i will see it happen, love the wide band, the LCARBs seem to have been a great 60$ investment, thanks for the support and suggestions fellas:
