I recently switched from 0 front toe to 1/16" toe out (similar to what you have) and I did not notice a significant change in balance.
imho throw another half degree of camber at the front, I'm at -4.0 degrees, have been at -4.2 and have heard a few cars trying -4.5 and even -5.0.
Everything else seems to be in the ballpark.

-4.5deg is resulting in a slight variation in wear across an A052 with more wear towards the inside for me. Not talking about too much though. I'll be dropping mine back towards the 4deg area to even out the wear.

22mm in the front? What dampers and springs do you.

Redshift competition coilovers. They are revolved B.C Coil-overs…. Running 8k f/r. With perin end links

Wait, so you have toe in up front? Yeah, that doesn't help anything.

You definitely don’t want any toe in up front. I run zero front toe, but some people like a little bit of toe out for better turn in. Since I daily drive my FRS, I run zero as a compromise.

The alignment machine stated .05 toe ( I’m assuming that would be toe out and -05 would be toe in. Is this the correct assumption?. If that is the case . Would toe put help with turn in or harm it.

positive is toe in which helps in straight line stability and is what most road cars have because the average joe just wants to drive down the freeway without spilling their coffee but hurts turn in since you have to turn the steering wheel further to get more direction change. It's wonky but probably not helping you if it's actually toe-in.

Edit: you have such a tiny amount of toe in at 0.05 degrees that I really don't think this is your root issue and changing it won't get you where you want to be if it's understeering enough for you to post on here instead of just band-aiding it with an air pressure tweak.

I have a question about spraying tires. I have Yokohama a052. I am attending the national tour event in Romulus N.y this weekend. Weather forecast is 80 each day. Slight chance for rain one day. Run in an old airfield paved with one section of concrete. First do you think spraying will matter with three runs, no co driver. 2nd. Do you spray side walls or tread, if so why. Thanks

I wouldn't spray the tires in those conditions. You shouldn't get anywhere near overheating the Yoks.

Thanks, just curious. Spray tread or sidewalls.

If/when you need to spray, I always spray the tread.

[steverife]

Most of your heat is coming from your brakes. I usually try to hit sidewalls first, then inside of the wheel as much as possible, then tread.

I finally have a starting setup (of sorts):

- GReddy/KW V2 coilovers 6k/7k (336/392)
- Karcepts front bar, full soft
- RPF1 17x9 +35
- 255/40-17 RT660
- Camber 2.5F/1.8R (limited by the top hats) 1mm toe F/R

Nothing fell off or made any strange noises on the test drive last night so I signed up for a local Saturday, we'll see how I do, it's been a while.
