SHIFT 2 UNLEASHED Tuning Tips: Tires & BrakesPosted on April 4, 2011
Everyone knows a car doesn’t perform well when it’s got a flat tire, let alone four flat tires. Using that as an extreme example, one can understand that by slightly adjusting tire pressure, you can improve the handling of a car.
I wouldn’t recommend solely increasing or decreasing tire pressure. It should be used in conjunction with the other tuning aspects offered, some of which I’ve already described. I want to reiterate that going overboard with one area can affect the rest of your tuning in a negative way. Making small tweaks to different parts will almost always garner better results than maxing out the settings on just one.
I decreased the front to 40.00, and increased the rear to 55.00, promoting oversteer. This immediately helped bring the rear-end around in the middle of the corner, getting the car pointed quicker, essentially allowing me to get back on the accelerator sooner. Anything larger than 10-15 in either direction is generally too much.
Whereas the tire pressure seemed to help in the middle of the corner, I still felt I was having to over-slow for the entry. By increasing the rear brake balance to 55.00, my entry improved enough to where I felt the car was helping me turn, instead of working against me. That being said, I wouldn’t advise going any higher than that. Couple your brake balance with a brake pressure between 10.00-15.00, and you should find the car acting more like it should.
Again, I can’t stress enough that while changing tire pressure may seem minor, small changes to multiple areas result in a better tuned car than giant changes in the more important areas. Make enough small changes and you’ll find yourself rising higher and higher on the Speedwall.
