The best way to measure pressure is to use a needle pyrometer which you stick in the tire right after your run. You take temps of the inside, middle and outside tread of the front tires.
If it's even across it's perfect.
If it's hot in the middle you have too much air.
If it's hot on the shoulders you need more.
Then you adjust the rear pressures to your liking.
Falken Azenis RT-615 in 195/60R14. Suspension is stock with most bushings replaced with polyurethane, alignment is was done recently factory settings. The LSD is 1.5 way clutch type and is fairly aggresive, it is a race unit. I know this is pretty much the only thing that changes the dynamics of the car significantly from stock, cuts down on understeer a lot, I think it's the reason I can make the rear slide pretty easily in faster corners. I believe I have around 38-39 in the front and something like 23-24 in the rear. I don't drive the car hard enough so that the tires get overheated or probably too much hotter than they get normally. Just a corner or two here and there on backroads I like, nothing where I can run hard for extended periods, not safe.
It almost seems to me that the pressure that is good for longer sweeping corners taken at higher speeds isn't as good for lower speed tight corners, like auto-x corners. When I purposely overinflated the rears with my old set, I liked how it felt in tight corners, it seems to be easier to get it to turn faster and not understeer, but it felt unstable and almost scary in faster sweeping corners, I had to take them slower because it felt like the back ran out of grip earlier. It almost seems like less rear grip is better from slower corners but worse for faster ones. I know in fast corners, as I push harder and am pretty smooth, usually the rear starts to let go first, but in a tight corner it's usually the front that looses grip first, it's harder to make the rear rotate, I dunno if that's a driving issue because I can do it sometimes with the same low rear pressure, it's just not as easy to do as in a faster corner. Braking for a lower speed corner is more difficult for me so maybe that's why, I tend to brake too early and not hard enough sometimes I cut in too early and don't let off the brake at the right second. I think it's harder because less time is spent braking and also when you start to brake seems harder to judge perfectly than for a higher speed corner. It's almost like with braking for a lower speed corner you're doing everything faster so it's easier to make a mistake if that makes any sense. When I do it right, it feels like the rear unloads a lot since I am on the brake hard enough and a quick cut in and a later apex makes the rear want to rotate, it just feels like the car doesn't really want to do it since it's hard to induce. I'm guessing it could be the stock suspension so overinflation in the rear compensates for that in tighter corners right? Even if it doesn't feel as good in faster ones.
Sorry if I blabbed too much or didn't make sense.
