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 |
