Update. Been a minute.

General/Life
Been gone due to life and stuff. I have so little free time but that's good. Working 3 jobs, fulltime student and Chief Mechanical for FSAE. Been designing entire suspension geometries and stuff. Exams and work have been bleeding me from the wrists though. I did recently land a kinda job for 4D Engineering. Raceshop but they play with the hillclimb cars for Pikes Peak. I say kinda as it's piece work and inconsistent. I'm trying to build more stuff for our platform as well, for my use and yours.

Rally
During the rally the car was cold, ran good. All that. There was a stupid amount of throttle oversteer which was a pleasant surprise. In the bad news I blew my shocks. Like Megadead. IC held well, overall was a good day.

New Parts
Since I last posted there's been some additions.
-Silvers 2 way Coilovers; nice pieces, haven't had time to put them to work.
-Aluminum IC-->Throttle body adapter. Fun fact OEM the diameter is 47mm. Our throttle bodies are 58mm. Thanks Toyota.
-Intercooler heatshield and turbo blanket; this stuff works, spools faster and engine bay is much cooler.

Status
Coilovers each dropped 2 lbs off each wheel, even with the 2way canister. Nice free weight savings. IC adapter was a day and night change for how simple it was. Boost builds harder and faster with much more induction noise to boot. Coilovers keep the car so much flatter but heck their rough. Havent had time to push them due to...brake failure...See when doing coilovers you have to undo the brakes. In that process we broke a bleeder valve. We fixed it, or so we thought, but I cannot for the life of me get them to bleed right. I'm trying again tomorrow to see what I can get moving.

New goals/next to do
Battery box install and straight intake. Everything helps right?
Full underbody aerodynamics. Flatbottom with routing and correct diffusing. Should be fun. Stupid amounts of engineering but I'll love it.
GTIII-RS turbo, boost controller, recirc etc. Just as it comes. My new boss at 4D is basically mandating to me that I have to make 400 AWHP.
Full custom exhaust 3"
Roll center correction kit
Clean up interior, flock and fix dash, flock doors, a pillars etc.

Anyways we'll see how race season goes. I'm entering into both track attack and rallyx. Hopefully I'll be more present here!

UPDATE:

Coilovers:
Silvers 2 ways are dope! I haven't been able to really dial them as I am still not fully aligned and my brakes are shot. More on that later.
Couple Notes;
-The rebound adjustment is under the car, no remote reservoir. Kinda a issue but I think I'm just going to bring race ramps with me to the track to adjust. Extra step but its what happens.
-Spring rates are just right, the car is stiff don't get me wrong but its still streetable, even in Colorado. I will def need some lower rates for rally though. 8k FR 6k R. Probably half that for rally.
-The adjustment does make some major differences, valving appears to be predictable but have a good wide band.
-Ride height is super nice as I custom ordered mine to be able to RAISE the car. 1.25" but I also lowered it about an inch so super broad adjustment.
-I'll have to get back on some things once race season boots

Brakes
My front drivers caliper piston seal went out. IE no brake pressure, on calipers that are OEM Toyota @ less than 1.5 years old. $180 a piece. So I have decided to go larger brake kit. My goals were to clear 16" rims as these are what I'll rally on but also increase rotor diameter, brake pressure, and consistency.
My solution was some Dynalite Narrows from wilwood with 12.09" rotors. Not a major size increase but a whole 2.5kg drop per front wheel on mass. I am building custom tophats, radial mounts, and powder coating the whole thing. I'll post a full engineering breakdown on the engineering thread. I did all the math on pressure increase, bias change, total heat capacity, etc. I also plan to add brake cooling ducts that are carbon and fancy.

Wheel Bearings
Ever hear a weird noise from the wheel and nothing appears to be wrong. Well its probably I kid you not, a grenaded wheel bearing. After touge driving there was a weird clank grinding sound. Thought my CV died. Nope we pull the wheel at my work and out comes ball bearing and steel shrapnel. Anyways there already fixed but the car drove about 30 miles with 2 wheel bearings pretending to be IEDs.

Next steps
-Turbo systems, Boost control and recirc, new heat exchanger for WTA
-Bodykit
-Aero, going to scan the whole underside of the car
