However, its unlikely 20psi is going to suit your needs.

That said, the real test: how did it feel once you did? Did it get better or worse?

i mean he literally said what you said and to try it out and ask a forum. so here i am. at 21 it felt ok but i still could feel break away. thus me asking in this thread

Which tires, size and wheel size are you using?

I've never run lower then 26 psi hot, started feeling inconsistent for me. I usually set at 29 psi hot and bleed down to 28-30 based on balance. Re71r 245/40/17 17x9, I've heard bfg and yoke like 1-2 psi more.

20 psi sounds like Hoosiers on a <2200 lb car pressures, not really relevant to this car/class.

Edit I see the size now, still curious about compound and I've run these pressures down to the low 50s, ambient and in the damp/wet. When it's chilly you usually have less grip as the tires don't stay warm, everyone is dealing with the same thing and it's just something to drive around imho

ok let me restate my question, i run 255/40/17 RE71rs. i normally run 24psi but was having sever rear grip issues in the cold at that psi. what pressure should i run them at since i have 2 more events this year and it probably will be just as cold

[Autoenthusiastasm]

Since I’m not planning on changing exhaust or header I would be only stage 1. Seems like a lot of cash for a single use unless it has a big improvement on tourqe and flattens the dip so to speak

It's third on my list of priorities for a reason.
Once you get the wheels/tires/suspension sorted the 15 hp from header+tune is the next few tenths to the pointy end.

24 psi seems really low to me. What are your camber settings?
I run 255/40R17 as well, but A052s. I don't dare go below 29 psi in the front as I'm already a bit warmer on the outside shoulder with some extra wear. Currently running -3.8 front camber

Rear I'm at 27-28 psi with -2.5 camber.

If it's cold and your having traction issues, it's probably not a tire pressure problem. Might just be because it's cold. Or perhaps it's cold and your tires are starting to heat cycle out.

I've never ran my car on Bridgestones, but 24 seems really low. Especially for 255's.

As far as adapting to lower temps, blankets help. And don't open your hood.

Another thought, and something I've played with at some colder events, is to take a sacrificial run with traction control on and hope to retain some of the heat that generates.

i thought about them being heat cycled out since ive been running pretty much every weekend this year. but i have the same camber more or less. -3.7 front -2.5 back. i asked one of the really good stx drivers what psi i should be at at the start of the year and he said 27 front 26 back but to check the indicator and temps since im on 255s and not 245s. i ended up dropping to 24 to get to the indicators

Seems like Perrin 22mm bar is most common. I was going to go with LPC LCA but I guess they are illegal u less bushing is changed out. I need to keep the height near stock because I daily and winter drive my car. If I want around -2.5 chamber in the rear can I get there without LCA’s? I am not changing my exhaust . Is the improvement in tourqe with the Unequal length header worth it? I’m Keeping my 7.5 wheels as I have brand new 225 Re 71s and need to use them up or sell before I get my 17x9 wheels. Do I need new endlinks for the front if ride height is near stock? Do I need the subframe (bushings - what do they do?). Is the tablet worth if exhaust is stock. I’m trying to spend my money wisely as my wife is keeping tabs. Not looking for National level build but competitive local mid sized region.

Have you considered SSC or do you want to bite the big bullet and go to STX?

I don't think those are supposed to be indicators.

I posed that question before and some say the ssc has some unusual handling characteristics. Plus there are not many running ssc. Lots running STX. The BRZ seems very competitive in STX.

well shit. this might not be relevant soon anyway, i might be selling it to get a more "practical" and "family car" my wife wants me to get. time to boost a wrx until it blows. sadly ill probably have to return it to stock, sell that, so watch for a part out in December

It is better with the new tire and adjustable end link allowance.

With that said, having competed in both, the car is WAY more fun with a header/tune, so I would recommend those. The car with my STX exhaust really isn't any louder than it was in SSC with the Nameless muffled track pipe.
