STX Rules and Setup Questions

Better gearing? Didn't it get a tad shorter?

[xwd]

It did, that's why I added the blurb about revving it to 8k. I know guys are already running the car to 8k or higher but I have concerns about doing that.

IMHO the 2017 would have been a better car with its gearing on the nationals courses this year and most of the courses I've driven this year, with an 8k redline.

I kind of agree on the gearing, just look at the ND's, people thought their 2nd gear would be problematic.

When I test drove the 2017 BRZ last night, I specifically tried to pay attention to the gearing. 1st gear seemed to pull good, once through the torque dip, and 2nd gear was OK but was definitely shorter. I think I saw max of 54mph in 2nd gear, but I was obviously not pounding it against the limiter as it was brand new.

Also kind of hard to draw a comparison with my tuned/bolt-ons car and a stock one. Having the torque dip again was awful, hah.

54?! That's major. I tag 62 at the limiter in 2nd...

[xwd]

Based on stock tire size I think the theoretical is 57. If you have a 7800 RPM redline the 4.1 results in a 62mph redline, with the new 4.3 gearing it's 59. If you rev to 8000 it's 61.

People rev up to 8k and over? Brave.

Keep in mind 54mph was not on the limiter, I remember the shift light just came on and I backed off and saw the 54mph.

I get to 61mph in my car with 7600rpm limiter.

I realize these are "silly"; but if you've seen my car in person lately you'll immediately understand the plan I'm hatching.

F:1 says you can

Your reason is a little more... extreme, but I have them for the same reason and I'm not sure it worked. You'll have trouble mounting, one of mine needs professional help unfortunately, on the side I had an incident and the body isn't perfect... It needs to tape to the side.

[justint5387]

STI lip, sideskirt, bumper valance, and diffuser are standard parts on the series blue package.

[2superblus]

So in short the answer is YES. As it was offered on the Blue series BRZ

I have fought this already.. As Bart said .."short answer is YES.. there is a bit more to it.. as it falls under "model" As it is offered as optional Equipment in the BRZ Accessories Brochure. I use it for Protection more than anything... otherwise the rocker panels and front bumper take a Beating as you well know. had mine on for over 2 years now.. with multiple National events.. and didn't have an issue...

From Fastrack:

"Street Touring
#19962 Is this legal for a STX BRZ/FRS?
Per 14.10.B, OE traction control systems may be electronically disabled. Members are encouraged to understand the limits of the allowances, whereby 14.10.B only applies to OE traction control systems and such devices may perform no other functions."

Did I miss out on some sweet rules-gray-area cheating? :P
