[QUOTE=DSC Sport;1596454643]I finally pulled my alignment sheets and the rear caster towards the end season was .7 so we were good and could be why it felt so good. Every time i track the car we try something different. but never both front and rear at the same time. When you do this i found its much easier to truly feel the differences.

I will look into modifying a pair of Granatelli bars to replicate the oem's in the spring. Common sense is toe out on turn in must help rotation. As we call it "no brake turn ten" at WGI rotation is king and a must to pull it off in the high 90's!

What are your thoughts on GM's new calibration or are they just copying your best set up for track and street?

Thanks allot for your help and thoughts.

[QUOTE=Mad Dog 24;1596460302]No run the granetelli the way it is dont re engineer it I have the curve calculated in the static toe setting
GM is a completely different algorithm and there is no comparison in theory. one is based on ground hook and looks at tire freq the other a combination of ground hook and skyhook that is why I offer you the ability to tune its completely user friendly. or run my off the shelf tune and its damn good. You will find the ultimate ride and performance that your shocks can offer with the DSC after that you have to step up and buy shocks with a true high speed range

[QUOTE=DSC Sport;1596462907]The DSC controller in "due time" as they say, thanks, .

I am headed to the alignment shop a 1PM today.

I would like an little input from you guys on what settings you would recommend to the DSC sport recommendation for 100% street use with no track and mostly interstate driving. My problem is planting power and snap oversteer which I hope that setting caster to .8 corrects. It's as if I have 200HP that I cannot use due to lack of traction with the current factory alignment which the settings are unknown.

That said, what changes would you make to camber to maximize straight line traction and what if any changes would you make to toe to maximize tire life?

Thanks in advance for your input!

If you're more into straight line acceleration I'd just use DSC's street alignment. If you're mostly street but do hpde's I'd say their street/track alignment. All of this info is on DSC's website.

Use the DSC Street Settings. As for reducing tire spin you do have to remember the LT4 has a lot of low end torque compared to most other high performance engines. Because of that you have a lot more Horsepower from 1000 to 3600 rpm than NA aspirated engines of the same or smaller size. Yes, there may be engines with the same amount of max torque but there are few that have around 440 lb ft at 1000 rpm. That means you have enough power to break almost any tire loose as soon as you drop the hammer no matter what the alignment is or no matter which suspension controller you have.

The alignment and the DSC controller may make controlling the car a little easier when the rear tires are spinning but you will still need to practice throttle control by rolling onto the throttle and modulating the throttle to keep wheel spin at about 17% (which means rotating about 17% faster than if they were gripping the pavement and not sliding). With as much low end power these cars have there is just no way to drop the hammer without shocking the tires into slippage.

Max tire life then 0 toe or close too front and rear. Max straight line performance then I would keep the camber to a minimum on the rear and front not a worry. You cant go wrong with the DSC.

Your one of many experiencing the snap over steer. My car almost saw a ditch over that issue when it had 200 miles on it. Scared the sheet out of me. Found the rear caster negative on the passenger side and positive on the drivers, thanks GM.

Yes scared or white knuckled especially in the rain stock is scary. Run the off the shelf DSC tune and the street car setup caster in the rear is critical leave all washers in on pure street I can't help myself when the car is setup right you can hang the tail out and have a heck of a time . Since setup the DSC way my C7 is pure fun

Has anyone had the new alignment for DSC "slip" out of place? Just wondering if i should get the granatelli links.

Is it ok to run DSC street/track alignment settings on stock mag ride tune? Going to have my car at a quality dealer (abel) and figured id have them align it to DSC settings before inget the controller so i can feel what stock is like at the track.

Mad Dog 24

Yes many of the stock GM eccentrics may slip out of place. It has to myself and our customers, DANGEROUS. We now install on ALL track cars these camber plates and Mark has plates for the Granatelli rods too.

Amt makes camber plates that won't let things slip. They also sell the Granitelli links with a plate that keeps it from moving as well. They work great. I have them on my car.

Great minds Dog. lol

I was told by the manufacturer that unless you are running slicks and/or extremely hard on the curbing, OEM parts are fine if torqued correctly.

In almost 5 years of driving/instructing, I have not seen my alignment slip. I am fairly easy on curbing though and run the Cup 2's....

I marked all my settings, and the OEM settings didn't slip in my case, either.

0DSC Sport

When you align the car make sure to always mark the eccentrics and put some serious torque into the fastener I double wrench them most all the cars we do are track cars we really lock them down and do the front the same way mark and put some fear into the fastener it will stay.

Car will be at the shop next week for oil, was wondering if i can have them do the DSC alignment street/track (not full track) on the car before I get the controller.

Just bought track wheels, tires, pads and aero and need to chill on the bank account for a month.

Poor-sha

The controller shouldn't affect alignment.

Pacembellum

I guess a better way of asking my question should have been, any issues running the DSC alignment on a factory Mag ride tune?

gpuglisi

No issues, do it.
