Can anyone help me out? I like the car a little loose. I have used the BFG KDW's at 45 front 42 rear in the past.

You'll probably have to do a little experiminting, but those should be good starting points. You may be able to get away with a little less air in the fronts with the V700's. As far as the rear goes, I wouldn't go any higher then that otherwise you won't build any heat in the tires. 2004 Focus PZEV 2.3L - KW sport suspension, SP camber plates, Eibach front swaybar, FS intake, FS Stealth exhaust, 3.82 Final, Torsen ATB, Prothane MM insert, E1 CSVT wheels 1/4 mile - 15.201@89.4mph

To get more oversteer in FWD you actually want to lower your rear pressures. You are correct that it depends on driving style however. The biggest problem most people have is they go into corners way too hot and end up trying to toss the car into it. This in turn causes severe understeer and no matter what the tire pressures are, it won't help. 2004 Focus PZEV 2.3L - KW sport suspension, SP camber plates, Eibach front swaybar, FS intake, FS Stealth exhaust, 3.82 Final, Torsen ATB, Prothane MM insert, E1 CSVT wheels 1/4 mile - 15.201@89.4mph

Qbert, maybe my theory is wrong, but I've read that you lower the pressure on the end of the car thats sliding out so if you have problems with understeer lowering a little can help. Think of this, more air in tire the harder it is. thats why its able to slide out in the rear. Now with our cars with the 4 link in the rear and "passive" rear steering you want some play in the suspension, so it can travel and make all those cool geometric changes Really i've set my car up both ways firm front, loose rear, and vice-versa... and alot of combinations in between.. I can tell you this.. alot has to do with the type of course I'm on. When in Peru I ran opposite setup as the SVT tour, and we were within .2 of each other, now driver skill has to have some factor. And when I ran the T&T I ran times so close to each other with both set ups... I can't say for sure which works better, heck I'm not sure which I like better.. Well..back to the garage gotta fix this beast... :P 99 Cougar V6 Tourmaline Green: MTX, KKM, Borla Dual...

You can definitely dial in oversteer by increasing the rear pressures, but this does it by taking away traction. Your rear tires will probably never heat up if you have them up that high. 36psi in the rears isn't even low enough to cause them to scuff the sides. Basically driving technique has more of a role to play as you stated. Drivers who like to go into corners fairly fast and trailbrake through them probably will benefit from higher rear pressures. I don't like doing this though, too much room for error and not the quickest way through the corner, well not with the Contour anyway. Doing it this way does not allow you to get back on throttle soon enough. I go into corners fairly slow with light trail braking just after turn in to get the rear end to move slightly. No later then mid corner I'm already rolling back onto the throttle. With the lower tire pressure in the rear the tires have the ability to heat up ultimately creating the most traction. Try a drastic change one day. Drop your rear pressures a lot, possibly down to the 32psi range. Not saying it will work for your driving style, but you may be surprised to find what the car feels like. I think you are correct on the course design playing a big role in tire pressures also. Sweeper course, like I run a lot, require me to run lower rear pressures. Transition courses should probably be run at a higher rear pressure. 2004 Focus PZEV 2.3L - KW sport suspension, SP camber plates, Eibach front swaybar, FS intake, FS Stealth exhaust, 3.82 Final, Torsen ATB, Prothane MM insert, E1 CSVT wheels 1/4 mile - 15.201@89.4mph
