4lb split was the wrong recommendation given to you. We have severe understeer in stock form, so it makes absolutely no sense to put MORE pressure in the front. That will just add more understeer and compound the problem. You can get up to -2.0 camber in front on the stock suspension with no mods - just an alignment - so there is no lack of camber. You should put more pressure in the rear to promote rotation.

Not all old timers. Bob Tunnell can whip the whole field without a single course walk. He and John Ames have both given the advice to focus on looking ahead rather than walking the course a lot. Do what works for you, but I don't consider it sage advice similar to the tire pressure split advice.

80lbs is what I do for daily, but 90-100 for racing as per the norm. I do also have aftermarket extended studs, lugs, and wheels.

 

For racing i use the 100lbs torque spec on the wheels and had never had a problem with any wheels.. warrtalon i have used a few several methods with tire preasure and so on . i came to the conclusion that theres a certain sweet spot for when tires have sufficient grip but then again it varies with different tires.. if you over preasureize it they will slide... if you under inflate them.. they will slide.. so maybe it has to do with different types of tires because with street tires you normally have to keep a good preasure in the rear for them not to fold over


to add:
No one can tell you an exact preasure to run.. You have to take responsibility to adjust preasures and feel what is best for your setup..

 

Well I have to say that autoX is AMAZING!!! I never thought I could have that much fun in my car. I'm hooked for life. I ran higher pressure in the rear, but obviously since I had nothing to compare it to, I couldn't tell if it was making a huge difference. My biggest thing is I need to unwind a bit more to combat my understeer (I went a little too hot into some corners). Obviously I wasn't the fastest, the only thing I cared about was if my times droped each time I ran, which they did. My best time was a 58 and the FTD was a 52 (evo btw). Thank you all for your input and I can't wait get back out there again!

 

Yep, Kierkergaard, that's what it comes down to - having fun, making clean runs and getting quicker each time out. Glad you enjoyed yourself.

As for the tire pressure thing, it's amazing how fiddling with that can make a big difference to the car.

I used to subscribe to the notion (for the past 3 years) of higher rear pressures helping the car rotate more but read on the tirerack.com website that you should actually run higher pressures in the front to promote oversteer.

I run Bridgestone RE55S semiclicks as my daily and autoX tire and have been running 30 front, 32 rear hot pressures very happily for wuite some time. So, curious to see what would happen, I reversed the pressures to 32 front and 30 rear one night and went out for a play...and wow, much more oversteer!!!!

I wouldn't have believed it if i didn't try it!

Point is - find a nice parking lot near a gas station with an air pump and try it yourself...especially ona stiock evo it's a fun thing to play with.

And PS, for street tires, the correct pressures for you will be much higher....I'd to something like 38f/40r or 40f/38r as a ballpark setup. If you run more than a 2psi differential between front and rear the results are even more extreme, I'm still playing with all that. But you have to monitor your tire wear and how far they're rolling over...each tire has a "sweet pot" beyond which if you go too high or too low you just start losing grip.

Note - for autocross it's nice to have some rotation but i still run 30f/32r hot for track use. I like to play with the tail but in the interest of quick lap times too much oversteer is too much of a good thing!

Now go play, and have fun mate!

 

I have found that track temp has alot to do with the tire presure split working. Colder tire temps = lower rear tire presure. Higher temps = higher presure in the rear. I tried the lower presures in the rear at devens last season and it worked in the morning, but as the temp went up I noticed the tires getting over heated and the car did not rotate as well. I went the other way and the car responded nicely. It all depends on your cars setup and your personal preference. Mark Dadio, (07 SM SCCA champ), and I shared my evo at an event and he jacked the rear presures way up. I could not keep the rer end behinde me and he was loving it. It all depends on what you like and what your skill lvel is I guess.
