FAQ’S – FREQUENTLY ASKED QUESTIONS are HERE
|Suspension adjustment||Affect on vehicle balance, extreme useable adjustment limit||Symptom of TOO MUCH adjustment|
|Front spring rate increase||More understeer||Terminal understeer, front of car hops in corners, excess wheelspin in FWD car|
|Front spring rate decrease||Less understeer||Too much oversteer, oversteer then understeer if spring is so soft that the car bottoms under lean, car bottom excessively with a jolting ride|
|Rear spring rate increase.||More oversteer||Too much oversteer, hop in corners, twitchy|
|Rear spring rate decrease||Less oversteer||Car understeers, if way to soft car understeers then oversteers as car bottoms out under lean, car bottoms out excessively with a jolting ride|
|Front antisway bar stiffer||More understeer||Terminal understeer, Lifts inside front tire off the ground which can cause massive wheelspin, also not good for most effective tire usage as inside wheel is now doing nothing|
|Front antisway bar softer||Less understeer||Oversteer|
|Rear antisway bar stiffer||More oversteer||Big time oversteer, Can cause the inside rear tie to lift off the ground which is not too bad on a FWD car. On Classics, if this happens while trail braking into a turn, the abs can shut the brakes down which can be a bit scary|
|Rear antisway bar softer||Less oversteer||understeer|
|Front tire pressure higher||Less understeer
Except with BFG R-1 tires. They will grip less and understeer more if the pressures are increased within a reasonable amount.
|No traction as tire is crowned so more understeer, bad wheel spin, jarring ride, center of tires wear out|
|Front tire pressure lower||More understeer
Except with BFG R-1 tires. They will grip more and understeer less if the pressures are decreased within a reasonable amount.
|Edges of tires wear quickly because tire is folding over, feels mushy, tires chunk because low pressure means more heat build up|
|Rear tire pressures higher||Less oversteer
Except with BFG R-1 tires. They will grip less and oversteer more if the pressures are increased within a reasonable amount.
|No traction as tire is crowned so more oversteer, bad wheel spin on RWD cars, jarring ride, center of tire wears out|
|Rear tire pressures lower||More oversteer
Except with BFG R-1 tires.
They will grip more and oversteer less if the pressures are decreased within a reasonable amount.
|Edges of tires wear quickly because tire is folding over and cupping upward, feels loose in back, tires chunk because low pressure means more heat build up|
|More negative camber on front wheels||Less understeer/ -3 degrees||Poor braking, car is road crown sensitive, twitchy, tires wear out on the inside edge|
|Positive camber on front wheels||More understeer, a little can make the tires last a little longer||Poor braking, car is road crown sensitive, twitchy, tires wear out on the outside edge You almost never want to have positive camber unless you are a dweeb|
|More negative camber on rear wheels||Less oversteer, more rear grip, less breakaway warning when limit is exceeded/-3 degrees||More oversteer, car feels twitchy in back, tires wear out on inside edge|
|More positive camber at rear||More oversteer, more forgiving at limit||Car feels twitchy in the back, tires wear out on outside edge|
|Ride height to low, rice boy style||Car twitchy with unpredictable dynamics, don’t race on when you see it because they will crash, taking you out||Everything that could possibly be wrong, sudden over or understeer, twitchy due to bumpsteer|
|Toe-in front||Car is stable while going straight. Turn in is average/1/8-inch total toe-in||Car has slow twitchiness under braking, feels odd, kills the outside edge of tires|
|Toe-in rear||car is less likely to suddenly oversteer when throttle is lifted/1/8-inch total toe-in||Weird slow rocking movement in back, feels slow but still unstable, wears the outside edge of tires|
|Toe-out front||Car turns in well, works pretty good in FWD cars as they tend to toe-in under load/1/4-inch total toe out||Car is real twitchy under braking, car is very road crown sensitive, car wanders on straight road, kills inside edge of tires.|
|Toe-out rear||Helps the car rotate, useful on tight low speed courses and slalom events/1/8-inch total toe out||Not too good for street driving, causes lift throttle oversteer, car makes violent side to side rocking motions in rear, tires wear more on insides|
|Positive front caster||Helps both stability, steady state cornering and turn in because the suspension will get more negative camber when the wheel is turned/ 6-7 degrees positive, negative caster is not useable||Can increase understeer, especially in cars with wide, low profile tires due to a non-linear increase in corner weight. Increases steering effort, SE-R’s are not easily modified to make this adjustable, FWD cars can see an increase of torque steer with excessive positive caster|
