Questions about prepping car for track.

Currently running ST coilovers Just picked up a set of SPL LCA's. Toe arms will be ordered shortly. I know better coilovers will help with adjustable damping but that wont be till later this year. I have another 1k or so budget left for suspension this month and hoping to dial in a good suspension setup. This will be my first time on a real track, been doing autoX as a hobby for the past couple years. Finally able to go full track as this is no longer my daily. Car has JRSC, sitting on 255's

What should i be looking for for an alignment specs. How much camber? front back and toe? Thanks for any help, really looking for a good starting point

Imho you can start for track alignment -3dg front camber, -2.5 rear camber, zero front toe, +0.15dg total rear toe-in. But different tires and different aero mods may need different optimal camber, so camber is best dialed depending from pirometer tire temp readings.
Also i guess that HPDE will load brakes much more then auto-x, thus you may also need upgrade pads & fluid.

^These are the most common alignment specs I see mentioned around here. I'd agree and say that's a good place to start. Depending on your confidence going into your first track days, you may not find you're utilizing the whole tire at those camber levels, so if you side on slightly less camber, that'd be fine too.

But, absolutely make sure your brakes are up to snuff. DOT4 fluid and track pads of your choosing.

Why are the USDM STI springs (B2010CA000) "not applicable to Limited with Performance Package"?

We know the lowering springs such as the RCE yellows have not changed over the years and they work well with the PP Sachs dampers. Following that logic, why wouldn't the USDM STI springs work well with or be "applicable to" the Sachs dampers?
Good question, @BaatLuk, I was wondering the same thing...

Honestly...I'm sure they work just fine with either damper. It's too bad STI never releases their spring rates though.

Alignment after RCE yellows (with camber bolts and adjustable rear LCA) - Good enough?

A couple of weeks ago, I installed the RCE yellow springs on my '18 PP BRZ. I also purchased and installed the SPC camber bolts and SPC rear LCAs since they've been recommended to "dial back" the alignment within specs.

I LOVE the way they ride and how the car handles now even more than before! I thought they'd be a bit stiff, but I think they're just right pairing with the SACHS.

Now, last week I went for an alignment. This is a reputable shop and the shop owner did the alignment himself in just over 2 hours. He said the front is fine but wouldn't result in more negative camber without camber plates and that the rear was "fine" for DD.

With the camber bolts in the front and a 20mm (.08") drop from the RCE yellows, the max negative camber the shop was able to get was -1.5 on both sides with 0 toe. I was hoping for -2.0. Is there any way to get more negative camber without moving to camber plates or is -1.5 sufficient for DD?

The rear resulted in a slight more puzzling setting. I was hoping for 1/16" total toe in but the shop had it set up in degrees: .08 degrees. Not sure how that compares since everywhere I've searched for a degree-to-inches conversion yielded in different numbers and results.

The rear LCAs helped bring the camber back a bit, but not enough. My left rear shows -1.3 and my right rear shows -1.8. Quite the difference. I was hoping for more adjustability with the LCAs.

Anyone know or have any experience with the rear toe arms? Would a set of adjustable SPC toe arms benefit in further adjustability in the rear to even out the camber between left and right or am I splitting hairs on a DD at this point?

(I apologize if this has been answered somewhere before, but I literally spent the last 3 days searching and reading countless threads and couldn't find a straight answer.)

There are other front camber options available here:
http://www.ft86club.com/forums/showthread.php?t=103609

In terms of the rear something seems off there. Did they give you a printout showing the before specs as well?

You shouldn't need toe arms. .08 is minimal and getting it exactly .00 isn't something all shops are willing to do since it takes a ton of time to get exact camber/toe specs and most people don't really care. Sounds like they did decent but you could probably find better next time. BTW is that total toe or each side?

For a DD I wouldn't worry too much. No reason to really have a bunch of camber for a car that isn't driven hard. Zero toe is best for tire life though.

Thank you for your input and for that link on the front camber options!

I've attached the rear section of the printout below.

The before specs will be way off since I installed the LCAs myself in my garaged and "eyeballed" the rear camber adjustments just so I can get it to the shop for the alignment.

I was hoping for 1/32" toe in on each side in the rear and an even camber between -1.2 and -1.5 in the rear. Nothing too crazy since it won't see much track time - at least this year anyway.

The toe is fine imo.

There is no reason they shouldn't have gotten the camber where you wanted seeing this. It's OK for now as a DD imo, but I would find a new place next time you get an alignment. Shouldn't wear bad but just rotate your tires like you should and it won't be any worry at all.

Growler Motor Labs in Plano, TX. They were very well recommended and have lots of experience with the twins and WRX platforms.

Any recommendations?
