Car squatting too much at the track. So I went to the track, and I had no issues hooking. Car made 440whp, m6, on a 27x11 hoosier QTP. launching between 5100-5600 rpms. I feel like I have a bunch of wasted energy, the nose is coming up really high, very close to lifting the tires, and the back is squatting super low. Cutting a 1.7 60 foot, viking DA coil overs up front, and some lowering springs (intrax? they're purple) with the heater hose mod and comp engineering cheap drag shocks. whats the Best course of action? vikings out back? Somehow lift the rear up a bit? I have about 200 lbs coming off the car this winter, and a lot of it is off the nose, so I want to get the suspension working, Thanks in advance!

Another thing I should mention, is I have a long torque arm set up, and I can't justify changing it at the moment. Just got the exhaust to fit perfect, and got the relocation crossmember in. Maybe down the line Ill go with a short one.

What hole are you using? You want the to be slightly uphill toward the front of car. Better shocks will be needed down the road some day but might not just yet. Research on lower control arm angle and you'll see how important the angle is for separation or squat in the rear.

If it's working now your not far off from what your car wants though. You could slowly try tightening up the front extension now. Should make the 60 a little quicker and take away some of the rear end squat. Just keep tightening the front until the rear tires don't hold anymore.

Good shocks in the rear are going to be very helpful in getting the 6 speed to leave well.
I had some Comp 3-ways that I recently changed out for Vikings and it's night and day difference for me.
Shocks won't fix suspension geometry, but they can help control things.
If the rear end is squatting then you have less than 100% anti-squat. You want as little squat/separation of the body and the rear end as possible.
Try bringing the ride height backup, you can use stock springs with the stock rubber spacer, or do the heater hose mod to drop it down a little.

What tq arm and what is it's postion?
Edit...just seen you have a long arm. But still wondering yhe position.
1.7 60s can be done with a m6 and 100% stock suspension with ftont bar gone with ease on a dr. So no need to reinvent the wheel. Maybe just correct a mistake.

I just ordered a UMI drag bar. the front is really loose, and the car hooks well. I'm thinking maybe stock rear springs, vikngs in the rear, and the drag bar will probably help a bit. then ill tighten up the front a little at a time. nose comes up pretty high which I'm sure is hurting my 60 foot as well?

The drag bar will help greatly. I have been 1.27 sixty with the same shocks you are currently using on the back. Do you recall the setting you adjusted the shocks to? I would get someone to video the tire from side view and watch in slow motion to see how the tire reacts when you hit it. You will more than likely be surprised with what you see. After watching the video your first thought maybe add more air.
Of course going to stock spring height and better shock is only going to help.
Good luck and be safe!

I forget the compression. it comes up pretty fast and slams back down, gotta figure it out. I'll watch a video and report back!

if you decide to do Vikings, may I suggest the crusaders over the warriors? The crusaders will resist rear squat better IMO.
