Got a track related question? I'll try to answer.

On a similar note, how do people feel about remote reservoir shocks? Good? Bad? Not worth the point cost in competition? Etc.

If you're hitting the bump stops, you'll see spikes on the G sensor on your datalogger. If you're not seeing spikes, you're not on the bump stops (or you're on them but very progressively), and it's not an issue.

Remotes are given points in competition because there is a distinct advantage to be had

Hmmm, I'm not quite sure what sort of spikes you mean (longitudinal? vertical?) or the duration/magnitude of those spikes. I am seeing longitudinal spike on a one second sort of period, but I think those are from my throttle steering.

What kinds of advantages do remote reservoirs yield? I've read that on lower end dampers they induce hysteresis into the shock's behavior so they aren't good until you get to higher end shocks, but once you are into that realm what kinds of benefits do they yield?

More control via more precise control of the damping, additional cooling, ability to change gas pressure on the fly, larger oil/gas capacity, easier access to adjustments, the list goes on and on

So today at the track, ambient temp ~80F, peak oil temp 258, coolant 225. I have a front mount turbo set up. are these numbers too high? should I focus on coolant cooling more? is air flow everything to keeps temps down or is there maximum threshold to cooling with just air?

So this weekend while I was at VIR I accidentally had a money shift, going from the top of 4th gear into 3rd. I think everything is still ok, drove the car home ~300 miles from the track and didn't hear or feel anything strange. Just wanted to know if there is anything I should look out for to know if I damaged the car.

I've done that twice on track.
My motor's done 10000kms since the last time, so I guess it's OK.
Not nice when it happens, and it happens quite easily.

Have the car inspected by a trusted mechanic. The valvetrain is where there might be damage.

While that is something that you never want to do (for alot of very obvious reasons); I think our engines are fairly resistant to damage from mechanical over revving. I've heard of several people who have done mechanical over-revs and not had any apparent ill effect.

If you are worried, you can have the engine borescoped to check the valves for damage. You could also have a compression and leakdown test performed but that would probably be difficult with our engines and the spark plug access.

One of the sacrifices this car made for its low center of gravity, near inaccessible heads. I'll probably take it to my usual shop for an engine/trans/diff fluid change and ask him to give the car a once over, just to make sure there isn't anything obviously wrong. It still feels fine, doesn't seem to be down on power or making weird noises so I think I'm ok with rolling the dice and not getting it thoroughly inspected.

If it does blow, that just means its time for a built NA motor, which I might actually have the money for if I'm unable to do track events for a while

Which wing do you guys run on your car?

I think most people don't put wings on these cars (at least for functional track purposes). Aerodynamically these cars are pretty good in stock form so it isn't as needed as other cars. That said I am sure some people have put functional wings on them and I there are people going more for looks who have "wings" on their cars.

I think the big question would be, what issue are you trying to solve with the wing?

APR and Voltex are the two go-to options, and we sell both

So I plan on tracking (or atleast Autoxing) my BRZ soon and want to get it more track friendly. The car is great and I have only had a few chances to really test it out. I figured I would ask this question here instead of started another thread. My mod list is going to be short. As of now CBE, Drop in Filter, chasebays wiring, adding OFT and Header soon, maybe switching to E85. This will be all I am doing for power.

Now for the Track. I ask that you order these Mods, What mod would you do first what would you do last. Heres what I gathered I should add to make the BRZ more track friendly.

Tires (OEMs have 14k on them, mostly highway)
brake pads and fluid
Bushings (everywhere)
Strut braces
Oil Cooler
Trans & Dif Fluids
Short shifter
Aero Mods ( BRZ Limited with OEM wing, no difuser)

Driver Mods will come first. Like I said, I need more time behind the wheel. These mods will be added slowly. Let me know what you would do first! Thanks

Oil cooler
Brake pads and fluid
alignment <-- actually helps quite a bit, especially with tire life

Then...

tires
other fluids
more brake pads
more tires
another set of tires
more brake pads, etc

The rest you only do after you identify a problem that is bugging you. You start changing some of those items and you can get on a spiral of mods to address issues resulting from a previous mod.
