0 '17 86s in DS because they're classed in CS
About 30 or so mk1.0 cars making up half the DS field

@imnotsureaboutbrz nothing will change about the classing because you'd have to prove that the '17 cars are no faster than the early cars to bump them down a class. The data doesn't exist to support a change. Just because a car doesn't show up doesn't mean it's improperly classed otherwise you'd see a bunch of cars nobody runs jumping classes all the time due to having only a few data points for reference. There simply aren't many '17 cars out there yet, most serious autocrossers got a taste of the early cars and decided whether or not to stick with them, the '17 wasn't going to change any minds and I guarantee they will be produced in fewer numbers so they will be rare in SCCA unless they get reclassed as an overdog.

I was playing with the idea of picking up a cheap street class car, one of the more attractive options is running a Boxster or Z3 in CS, <$10k buy in for a 6 cylinder roadster, might stand a chance on the faster courses if the lack of camber doesn't leave them hanging out to dry on the sweepers...

A lot. Over half the field is Twins. There are 58 cars in DS, and I got to 32 before my browser on my phone jumped and I lost my spot. Decided I didn't wanna start over. I'd guess around ~35

@justinco and his codriver are the only guys running a 2017 MY Brz in STX.

FYI he's 25th out of 58 after the first day!

CS was a shark tank this year.

I really liked the the east course but just couldn't quite put it together over there. I was not looking forward to the west course but ended up getting the run I wanted there. (More or less)

-Would have liked to get a twin deeper into the trophies but my driving was stuck somewhere between "not bad" and "pretty good" when a lot of my competition was busy being AWESOME.

Justin really improved on the other side. Congrats justinco.

Congrats on the trophy! Impressive.

Does anyone know the stiffness of the front TRD bar compared to stock? I can't find a number on it besides diameter, which isn't enough to calculate stiffness without knowing the arm length.

I don't remember the actual percentages, but I do remember that the front bar increases stiffness considerably more than the rear bar.

The first day was tough, I did not drive too well

Thanks

Made a couple suspension changes for day 2. Had more confidence in the car and was able to drive it good enough for a decent come back. Happy with the trophy! With better driving, a better result is achievable for sure. Time to start prepping for 2018

Currently running RPF1's w/ 245/40/17 Rival S 1.5, hawk street/race brake pads, spec-D tuning catback, and about to do OEM crash bolts with custom alignment.

Well I have koni yellow's on the way, I'll keep y'all updated with how the car does compared to the sachs once I'm on them and have a couple events under my belt on them. I know it won't be a great sample size but at least we'll have some kind of idea on it. I have another BRZ driver (DS) in my region and I'll get him to drive with me some to see what we can figure out!

The Konis are pretty good and I assume you bought the full-bodied ones? I know it's been hounded on here, but make sure you get the washers from Koni so you're legal in CS.

Have you driven the Sachs vs. regular OEM shocks?

They are full bodied and will have washers. But I have not driven on the OEM shocks.

I'm also looking at getting a front bar but wondering if it'd be better to get the koni's set up like I want first, then retweak when the bar is on. Or throw konis and an adjustable front bar together and work it out that way.

I just switched from the Perrin 19mm front to both TRD package bars, and I need more seat time to figure it out (and the BFG tires). I have not driven a 2017 and not sure if their stock bars are bigger, but I would do the bar too. I'd warn against going too big on the front bar, but I've found that any size can work if you adjust your driving style.

I broke the rule of changing lots of things before the biggest annual event, and my car felt great but was a little unfamiliar to me because of the changes I made. I think I'm now in the boat of getting the car how it should be, then make incremental shock, bar setting, tire pressure changes to get where it suits me best. I just need to find the money for the fancy shocks.

When I ran the TRD springs and sways, the car understeered. I ended up using the TRD rear bar and an ST front bar on the soft setting.
