Drag Racing Coilovers ...

This transfer is a 2x blade as it allows the car to put power to the ground. On the other hand, our IRS really kills the tire contact patch and as it cambers more - as it squats. You loose so much tire contact patch that we loose a bunch of traction.

What you want for our car IMO is as stiff of a rear as you can so we minimal - camber as the weight shifts to the back. The front should be able to rise and compress in a equal and smooth fashion as to allow the car to b level out in one smooth action as to not disrupt the weight transfer from the back wheel.

Just think about it some. Stomp on gas weight transfers to the back. If the front is smooth and bounces up and down, with ever time your head dips weight is transfers back to the front (this means rear just lost lots of traction). Ever time the head rises again on the bounce, the rear suddenly gets more traction and blast off again lifting the front again and the cycle continues.

I have done lots of research on drag racing over the last few months. All this info is just from my own research which I have yet to test. I really don't want to spend the $$ on adjustable coilovers just for 1/2 a second.

Anyhow, how I would adjust/dial in the suspension roughly is by doing burn outs as I don't have a long track readily available to test and tune. I would do a quick burn out and then inspect the rubber on n the road. First Try to adjust the front for a nice steady and controllable rise and fall. then try to get the back burnt rubber to be as even on the inside and outside as possible. Yes it's not perfect or the ideal was to set up a racing setup but it should work, at least in my head.

I did the cheapest thing as zeroed out everything on my car, camber, toe on all 4 corners and runs nt05r drag radials. I do ok but still upset that im far from 11's with all the $ already spent.

I'm looking to buy a fishing boat so that's why I have not upgraded my suspension, get an LSD and ecutec.

Me likes fishing too and gotten into it again.

Our cars don't really lift the front enough to bounce [not yet at least with stock suspension] this is due to the IRS and the squat.
Your conclusion here regarding the shift of weight transfer and loss of traction and acceleration in this instance is spot on though.

I also am limited in doing 'test hits' to dial in the launch - RPM, Traction Control [EcuTEk], etc.
No real safe out of the way place to do it since I live in a congested metropolitan area.

I can get away with one test maybe, but then have to keep moving on.
I did try doing short burn outs with my buddy watching from behind...observing the amount of squat and the contact patch.
The 19" M/T's did a fair job of countering the squat at '0' camber during the burn outs.

The LSD and the EcuTek would help you towards your goal of getting in to the 11's.

I think the Drag Racing Coilovers would help as well.

1/2 second IS a lot of time when it comes down to it at the Drag Strip.

Good luck on your Fishing Boat ...lol... [seems that Fish are a lot smarter than me, never had any luck at all catching them ]

The front end does lift some. Not as much as other cars but it does. I think she will lift more as the back end gets more traction and really launches her out the hole.

I also forgot to mention that I run stock tires in the front and NT05r at the track.

I pump up the front tires to 40 psi to help shift some of the weight to the back (it's minimal but I believe it helps some). The back drag radials are dropped anywhere from 25-20 psi while hot. I swap my rears out at home on the lift then drive to the drag strip on them. By the time I get there and pass Tech, they have long been warmed. I drop the rear psi then.

AMR

STRANGE
Will look in to them as well ...

Did go down to AAM in Maryland to check on the car and pay on the bill [ouch]
Got to test drive it a little and got some verbal numbers too ...
They are sending me the Dyno Graph next week...hopefully that is.
SEMA is coming up and they are getting ready to travel
