I'm spinning out of the hole with 1.8 60 foot times to a 11.220@123.I just ordered a Spohn Rear Anti Sway Drag Bar and would like opinions if Lower Control Arm relocation brackets are also necessary to help hook up? BTW, my car is not lowered

Below are my suspension mods to date:

SpohnAdjustable Tubular Polyurethane Ended Trailing (Lower Control) Arms
Spohn Adjustable Tubular Polyurethane EndedPanhard Bar
Energy Suspension Polyurethane Transmissionand Torque Arm mounts
Prothane Motion Control Polyurethane Motormounts and bushings
Competition Engineering 3-way adjustable dragshocks (rear),
BMR adjustable Torque Arm
Kenny Brown Double Diamond Subframeconnectors

+1 on what tires, that car should be pulling 1.4-5's with ease.

IMO Adjustable shocks are more important at your power level than a drag bar even a stock style drag bar like the spohn. Not that it won't help, but if you weren't having a ton of chassis twist off the line then that wasn't money best spent IMO again. Most of the time a car at your weight and power just doesn't have the torque required to twist up the chassis to where that drag bar will actually significantly reduce the short times, where a set of even single adjustable shocks will be like night and day between getting down the track everytime with the most power out the hole you can throw at the car and using the suspension to adjust the 60' and not the power output or the launch rpm of the car.

I don't mean the 3 way one's either like you have not hating just trying to help.

What are the set on now?

:chug:

The clutch assembly needed to run on a Drag Radial or any radial requires something more then most will never deal with and the cost factor is out of sight and thats on a drag only set up.

That call is not needed yet. He's not making the power to make that call.

His problems can be solved here with a tire change and suspension tweaks.

I have gotten cars like yours to hook on the street with no suspension mods. Madman is in the business to make money and there is nothing wrong with that. He is the guy I would go to when I am trying to make a car put an extreme amount of power to the ground and I don't mean 500-600hp I'm talking 800+

Thank you all for your input. The car was running on street tires with MT 275/40/17 Drag Radials. I was foot braking at around 2700-2800 at launch

As for the transmission it's a Rossler 4L65E Terminator-3 with Yank 3200 Lock Up Stall Converter. I decided to go with the 3200 so when I go to the bottle it won't flash to high coming out of the hole and reduce top end slipage.

Really? That was your answer to the OP's question? :nono:

OP, the tire you have is more then capable of cutting better 60fts the a 1.8x so something with the car's suspension is definitely not working. I agree with the shocks being a good suggestion and yes by all means so relo brackets may do wonders for you.

So why don't you give him some advise, since your so good :funny:

I will, since you can't.

OP, since your torque arm adjustable, you need to check your pinion angle for starters. It doesn't have much bearing on hooking but its something I like to check first since it will give you an indication if something is out of whack. -2 is where it needs to be. I have played with that number depending on how the suspension is mounted (rubber vs poly vs solid).


The second thing, I need to know the settings of your shocks. The more settings you have the more complicated and sensitive it is to changes. In the rear you don't need all those adjustments. The cheap ass Strange adj shocks work good in the rear. Adjustability comes in play more on the front suspension for transfer and rebound.

Also, I would like to see a vid of the car launching at the track. If you can get that for us it would be a big help in seeing how your car is reacting.

Hey, csj2ta its spelled "advice". So now, I gave both of you advice.;)

Just to show you how I hook on the street. We are the car on the right. Fast forward to 2:20. No relocation brackets, no adj. torque arm. 26" hoosier slick.

Pinion angle is set at -2. Adjustable rear shocks are set at 30/70

Hey I can do that!!! :D

Mine isn't on the street though:(

Compression was too loose in the front on that run and tire pressure wasn't high enough so it came down kinda hard. Thank god for SYA bars.

Need a vid Bill. I need to see how you drive plus I need to see how the car is reacting.

id have to say adjustable front shocks are needed, a video will help. but w/out any adjustment up front to allow the car to plant the rear tires, those comp eng rear 30/70's are gonna do the trick. i kno from experience. relocation brackets in the the bottom hole. and as 87silverbullet said - a video will give everyone responding to this thread an idea of how its leaving a lot better than description.
