understeer

[Brad Roberts]

JHandy,

I know what track you are running. Have you met Fedrick in the BoxsterS yet at your local Austin track? Have you seen him POLE VAULT ahead in lap times recently? Ask him who helped him dial in and setup his ill handling BoxsterS He had never owned a water cooled Porsche until this his current S. He owns a shop in San Antonio that specializes in early air cooled 911's

JHandy,

I autocross. Those are low speed events vs HPDE which have much higher speeds. Things that work for me (like the big GT3 bar) might not work for you.

I suggest that you go with 35psi all around. And then the critical thing is to get someone else to drive the car and let them tell you whether the car understeers too much.

In high speed events understeer is the best friend a novice has. If you listen to everything you read here, you might make your car dangerously loose and end up leaving the track backwards when you run out of talent.

It's something that's easy to happen - a novice overdrives the car into corners and gets understeer because he is going too fast, he adjusts the car until it doesn't understeer in the slow corners and all of a sudden it wickedly snap spins when he lifts a tiny bit in a fast corner.

SO make your changes slowly, one at a time. Get opinions from experienced track guys. Get someone to drive your car.
