Not sure where to start with this, but I'll start with my setup.
Iron block H/C 6 liter LS, soon to be LSA this fall. 4L60E
Front:
Stock SB coil springs (new)
G Comp 2" lowering spindles
90/10 Calvert Racing Shocks
All other steering and suspension stock
Rear:
Stock multi leafs
Steel 2" lowering blocks
Calvert Racing 9 way adjustable shocks (relocated inboard and behind axle)
Cal Tracs
Here is my question. My main focus was traction and going in a straight line. Basically drag racing and straight-line street fun. It for sure sees more street than track. I researched 90/10 shocks and read some guys said its sketchy AF and some guys are like iv ran them for years with no issues. And I will say, its definitely different. But im having bump steer issues. Its not often, but it will do it going slightly downhill with a small dip at the bottom and when it does it always darts to the right. have never got it to do it any other time or anything over 45 mph. Going down the highway its never done it, just bumpy windy two lane.
I know X and F body A-arms arent the best for geometry. And im not afraid to swap to the tubular variety but dont want to if I dont have to and especially still have bump steer.
So, my questions are this:
Can the 90/10's cause bump steer?
Could it be the factory A arms because its lowered? (it drives straight as a string)
Should I swap to single adjustable front shocks and ditch the 90/10s? (stiffer on the street, softer on the strip/race)
