Indy 19S4 Afternoon

The Truck gets looser over a run you will need to make it tighter early in the run and if it gets tighter you might consider loosening it a little bit early in the run.  

Set Starts off tight and gets looser as the run goes on.  If it is too loose at the end of the run consider adding some more spring to the left rear.  Other options would be ballast forward or trackbar down.  The opposite will loosen it.  I strongly suggest you put in a full fuel run before adjusting.

Adjustments

Overall Tight/Loose: Trackbar up will loosen and trackbar down will tighten.  If possible move both sides equally.  Cross Weight can be used as well but it is a complicated process

Entry Tight/Loose:  Ballast forward will tighten the entry and Ballast back or negative will loosen entry.

Exit Tight/Loose:  Rear spring split.  a larger spring split will make it turn better on corner exit and a smaller spring split will tighten it on exit

Long Run Ballance:   Ballast will have some effect on the long-run balance,  back or negative will wear looser over a run and ballast forward or positive will wear tighter over a run.  In general,  if the car gets looser over a run you will need to make it tighter early in the run and if it gets tighter you might consider loosening it a little bit early in the run.  There is a lot of give and take between short-run speed and long-run stability.

UDATED 11/14/2019

The truck was pushing center off in the practice room last night so we reworked the rear spring package and ballast.  Truck is fairly nuetral for the first 2/3 of a run and then starts to move to the tight side.  For long run ballance try moving the ballast back or negative  and inch or two and resetting the front ride heights with the front right spring perch.  Minor adjustments should be made with the track bar.  If a big swing is needed try dropping the left rear spring 25 to 50 lbs and resetting the ride height on that same corner.

Michigan Afternoon

The set felt good at a hot afternoon Michigan track accross a full fuel run. As alwaysit id highly suggest you put in some full fuel runs before you run it and after any major changes.

Adjustments

Overall Tight/Loose: Trackbar up will loosen and trackbar down will tighten. If possible move both sides equally. Cross Weight may be the best adjustment on this set for tight/loos accross the long run but biut not by much adjusting crossweight on these coil bound sets is a complicated process. Try to maintain that front left spring deflection as closely as possible if you adjust crossweight.

Entry Tight/Loose: Ballast forward will tighten the entry and Ballast back or negative will loosen entry.

Exit Tight/Loose: Rear spring split. a larger spring split will make it turn better on corner exit and a smaller spring split will tighten it on exit

Long Run Ballance: Ballast will have some effect on the long-run balance, back or negative will wear looser over a run and ballast forward or positive will wear tighter over a run.

Dover Shared Base - S6 NTM 7

The set felt good at accross multiple runs Wednesday night. If you take care of the tires they will have not problems making a full fueld run. If abused we've seen blowouts halfway through a run.

Chicagoland 20S1 Shared Base NTM V7

The set felt good at accross multiple runs Saturday night. If you take care of the tires they will have not problems making a full fuel run. If anything this set is a little on the tight side after the tires heat up and if you abuse the RF it will get extremely tight.  If you can handle a looser truck those first 3 or 4 laps I suggest you loosen it up a bit and as always id highly suggest you put in some full fuel runs before you run it and after any major changes.
