Ouch indeed.

We're working on a motorsports grade Tegris unit now which will be mounted to the crash beam solely. Perfecting it now on car/in CAD and designing/finalizing it so it will be very modular.

Yikes, that was rough. Glad everyone is ok!

Need to teach Dave how to spin Ricochet properly! =)

That was quite the tank-slapper. Nicely done!

We've already started pulling out the interior... That didn't take long. Figured since we splashed dirty water all in the car, might as well strip it out and cage it!

Obvious question: Was this the fault of the splitter? Well, yes and no. It's an inherent problem with racing a "street" style splitter that hangs on the front bumper. When the splitter digs in, the bumper has to go with it. This is part of why you see most racecars have separate mounts for the splitter and the front fascia, or at least have a frame mount that carries the bulk of the load with a few cable stays up at the front. Velox made a great splitter, we just smashed it up. Incidental durability testing, if you will.

So where do we go from here? Well, it's racecar time. We were planning on testing out a Grimmspeed strut bar and Essex brake kit this weekend, but this kind of stalled out those plans. Coming this weekend, we'll start gutting the car for a full cage. We've picked out the seats we're going with, and we'll document everything through here as we go.

Stay tuned, it's racecar time!

Interesting read. Yes, most of street style splitter mount on front bumper resulting in several issues (not gonna go full depth).

iirc Driveway Labs' v2 front slipper do mount directly into the chassis instead of front bumper. But sounds like Velox is working on front slipper that mount to the chassis, so it'll be interesting to see what/how it'll turns out.

Ouch! Good to hear everyone is OK.

Which Essex kit? Endurance, Sprint, or Formula. I hear you are a dealer now. Looks like I have someone local for when I decide which AP Racing kit...

Endurance. I ran the numbers myself, as if I was going to design my own kit, and they came to the same decision I did. The front bias is a little higher, which is what you need for a race tire.

That, and the awesome caliper mount with integrated duct.

Ouch! hope its not to torn up... insurance claim? lol

GSpeed · 10-29-2015, 10:01 PM

Nah, it's really not that bad. Just tore up the bumper cover. A new one is only like $300 from Subaru, so I'm sure we can find one for cheaper than that. For a bad off like that, that's pretty cheap.

If you can enlighten me on that part. I'm not gonna BS say I know everything, cuz I don't. Why do you want front bias higher if you have racing tires? It's honest question.

GSpeed · 10-29-2015, 10:49 PM

Higher coefficient of friction means more weight transfer to the front of the car. So more bias towards the front means you've got the braking force where you want it. Of course, this thoroughly confuses the EBD system, so something like Beastronix's device is a lifesaver.

Like the install Jake! Looking forward to the results. Email me if you need anything.

Any idea as to when you will have the factory button housing?

Thanks! Kinda make sense... but at the same time, kinda don't. I'll do my homework

I have an extra FR-S front bumper in very good shape. Too bad it will cost more than the value of the bumper it'self to ship it to texas. ($350 to fed-ex to Austin when i checked) lol

GSpeed · 10-30-2015, 01:19 PM

Thanks for the offer. Like you said, we'll probably just buy a new BRZ bumper.

See you later, interior!
