This weekend was my first time with the Boxster at the track.

to cure the understeer, we want a bit more grip up front. we do this IN THIS CASE by adding pressure to the front tires.

i say IN THIS CASE because people will argue that increasing the pressure will DECREASE grip & that lowering the pressure will increase the size of the contact patch & add grip. tires are funny things. above & below a certain range, lowering the pressure WILL increase grip. however, within a specific range, adding air actually increases the efficiency of the tire & adds grip.

at any rate, i know from experience with THIS tire and THIS car that 34F/30R helps to neutralize understeer. give it a shot.

I never have issues with front end grip, it is mostly about balancing it with the rear with my set up so getting more front end grip isn't normally my concern. I tried running larger tires up front (actually due to stock sizing not being available in time for the next track day) and the extra grip in the front slowed things down as I wasn't able to get on the gas as early coming out of high speed corners.

What tires / sizes are you running?

I find that a 26psi to 28psi cold temp all the way around gives a dead neutral car on most "R" tires with my setup. I guess alignment and other issues have a big part in our tire pressure balance front to rear and car to car.

mdex - keep in mind you're running r-comp & the OP is running street tires. also, his car is stock. if you're on r-comp, i'm guessing you have a few other bits installed that help neutralize the handling.

True that... but driving stock cars as well (and even on street tires!) I still have found that most understeer can be dialed out (or at least back to the point that most people don't notice it) with alignment.... which gets us back to the original posters question as well, not that I am not enjoying our discussion on set up overall with our cars.

I just looked at the top of my shock towers to assess the camber situation. It looks like they dialed out as much camber as they possibly could. There is a ton of room to add more. :dance:
Looks like an alignment is in my future.

Great thread! Sorry diverge a bit:

I have a great deal of trouble balancing the Box (stock S with 15/23spacers) while in power on oversteer ( I hope this is the right term). Things seem a lot different in this car. Yes I am a novice driver and as some of you may have guessed already this would be in less than dry conditions. What is the single most disruptive driver input in this case? I would think coming of the throttle too abruptly would be the worst, second: over counter steer.

The slide is great fun until I come to my senses and want to properly correct it. What is the proper technique?

the trick is to manage your angle of attack. in a front engine car with a long hood, you can throw the rear WAY out and the heavy weight of the engine up front acts as an anchor, helping to pull the rear back in line. in a mid engined car with all the weight at the center, it's very easy to pass the point of no return. the RATE of rotation will also be quicker, so the driver will have to react faster. react is really the wrong word; you almost have to anticipate & start dialing in correction ahead of time. practice and be careful!

Yes, definitely.....but I actually feel that I am over correcting and getting back end fish tailing as a result! It could be that I am letting off the throttle when I shouldn't
