IPD bars help?
They ought to help with the understeer, but not with the dive. That’s a function of suspension geometry and spring rates at either or both ends of the car. If you want to fix understeer, here’s a list in increasing order of cost: 1. Pump the front tires higher. Cost: Free. This will reduce the amount that the tire rolls over under cornering loads. If you drove this car on a dealer’s lot, it’s probably 20 to 25 pounds too low all around – they go for that boulevard ride every time. Start with the maximum printed on the sidewall and move up in 2-lb increments from there till you can’t observe a change in the car’s behavior (or you dislike the way the car behaves), and then back off two pounds. Tradeoffs: On the plus side, this will sharpen steering response even at small movements of the wheel (say, tracking a lane on the freeway). It might also help fuel economy, but not as much as pumping all four tires up to the higher pressure will. On the minus side, it will make your car ride a lit
