Hey fellas im in need of some help getting my car to hook up. Its a stock suspension camaro with a sb/th400, it runs mid 10s with 60foots from 1.41 to 1.55
I leave on the transbrake at 4200rpm ,whippes the tires around 2 or 3 times then goes. I had 3 way comp engneering shocks on the back and stock preloaded sway bar. I junked that stuff for qa1 double adjustables and wolfe sway bar, but not tested yet. Shocks are 0 rebound 12 compression.
Theres 90/10s and moroso trick spings in the front, copy of s&w torque arm, lca's in the bottom hole and 28x10 hoosier slicks.
Am i headed in the right direction with the shocks and arb? Should i have a shorter torque arm with a lower powered car?to hit the tires that much harder?

 

Stiff wall tire? How many passes on them?

 

Not stiff wall, 4 months old 60 or so passes with lots of hole left.

 

Sidewalls are probably toast honestly.

 

Why 4200 on the brake? What converter is in it? Did you always leave there?

I leave at 3500 with my 355...and it goes the same 60' as leaving at 3100..just does a better wheelstand.

Id look into some fresh tires...see if thats an issue...

 

Btw...i run a spohn pro t orque arm and stock rear shocks..same front struts.

 

These cars are too heavy to run anything but a stiff sidewall and expect them to last more than 40 or so passes.

 

Ive got 60passes on my radials and have a little bit of tread left...barely!

 

A 28x10.5Stiff would last 100+ on my car. The radials last about 40-60 before the tread is gone. The non-stiff would beat the Sidewalls out of them before the tread would be gone.

 

Ive tryed leaving from 3000 all the way up to 5200 and still spins the tires.

 

Tires have to be done...if they used to work and not now. Nose heavy cars need all the help they can get for traction. I thought my radials were gone...balanced the car and it launched better than before...and i added 100# to the rear of the car.

 

I ordered a set of mickeythompson 3055s. Ill try that. thanks for the help guys.

 

i am not a believer in the sidewalls going away thing.... yet. ran standard sidewalls for probably around 100 passes or so with no signs of going away. i run a s&w torque arm as well as moroso front springs. i would say that if your car is spinning at the release of the transbrake, you should try to move the lca's lower to make it hit the tire harder. i normally ran 12lbs of air in my hoosier 28x10.5's.

 

This summer i tryed a shorter tq arm. 25 inches from the front tq arm bolt in length. I had the best traction with this set up but it was hit and miss and the tires where new then.
Then i tryed the pete z bars and that was a complete failure, Spinning everytime.
Both set up where with the cheap shocks and stock sway bar. Ill try stiff sidewall tires and go from there.

 

how heavy is this car?

 

Its never been on any scales. I wouldnt say its lightweight or anything. Everything i took out i probley added back in with the cage and the s60.

 

Stiff sidewalls all the way, try tubes as well.. I would also agree with sidewalls being shot, mine go very quickly in my stick car, and had same issue in 87 when Auto.. I have pics with 12 lb of air and wheel almost on pavement on launch - however short tq arm also.

 

I finally got to try it out. 1.37 in 60 feet all day long. It seprates a little too much but i never seen any pictures untill racing was over, somthing to work on next year. Thanks for the help guys.

 

Nice! Looks like it is working well now!

 

I did a couple things to help separation in my 87, stock location of LCA's and lowered rear, mine would separate till shocks fully extended.. If still issues get single adjustable shocks as they control extension not compression..
Nice launch.

 

mine seperates like that if it does a wheelstand. if it stays down its normally ok. i think when the car is at such an angle, the rear tires try to run out from under the car and thats why it seperates so much.

 

what torque arm is in the car? i noticed that the short torque arm cars (like mine, running a jegster) would seperate more than a longer torque arm...wonder if there is anything to that?

 

I copied off the s&w tq arm. Its 53 inches from the front bolt hole to the heim joint in front i think. I used a slider instead of a shackle, you can see part of the tq arm crossmember in the pucture.

 

What changes did u make?

 

double adjustable rear shocks, arb, and stiff sidewall tires.

 

can you tighten the front shocks any?

 

no comp 90/10s on the front

 

try some limiters up front..... should be able to pick up some more in the 60'.

 

Do you get any front end wobble that you can feel in the steering wheel after the front vines down I have similar front end setup and mine shakes like crazy if I really get aggressive off the line. Are u running a steering stabilizer?

 

i dont run a stabilizer and mine doesnt do the wobble when it comes back down.

 

You running s 10 steering box? Im running p/s box with lines looped thinking the slop in the box is causing my really bad wobble. All new front suspension/ steering parts too

 

yes, s-10 box in my car.

 

I had the real bad wobble and it was worn tie rods and stuff.

 

I replaced the tie rods etc with my s10 steering box and it shakes a lottle but actually lands pretty easy 60' out from 1" off the bumper.

 

I had the whobble at the first of the season. Bought the ed quay steering damper and it hasnt done it since. I still have the ps box with the lines looped. Mine shook so bad i thought the wheels where falling off.

 

Haha thats funny...not really..but mine just shakes like 2 degrees left then right in a split second then fine. Actually lands easier now that it goes up higher

I think a lot has to do with your engine trans and gear combo...makes it drive out and down easier on the car...or a poor combo drops like a ton of bricks. Limiters may make yours perfect.
