Buy a 2020 ?

It’s very clearly a six port in that photo. The flex tubes are a dead giveaway, 2 port doesn’t have that.

If you run a harness, you want to run a HANS device. I personally use a Rev2 HANS device with a six point harness. You can get away with a 4-point ASM harness but the six point is a much better idea.

Dashbuilt uses backing plates plus 3+ bolts per plate. StudioRSR has no backing plates and even uses rivnuts for mounting. They are basically show car rollbars.

Yea that thing isn’t going to pass any NASA tech. Unfortunately time trials like grid life, etc are very “light” on rules. Even the SCCA Time Trials rule book states only 1 bolt needed, which is unfortunate.

OEM Brembo fronts can be found for $150 each new.

I do, I read the rule books, and this car isn’t a drag car, nor is it going faster than 10.0 1/4 mile.

That is not correct. NHRA, NASA and SCCA all allow bolt in roll bars per their respective rule books.

The part you already have is a bmw part. Exact same thing. Toyota doesn’t make the same part in a different factory with Toyota stampings. “Nice bmw!!”

275/40/18 is closer to stock ratio if you care about your speedo being more accurate. It’s the size I run with Nankang CR-S tires. 30 and 35 will make the speedo be off. 295/30/18 had my speedo off almost 10 mph at 130mph.

It would start leaning out once the fuel trims max. Since the Supra runs 14.3-13.8 already at WOT, running leaner is really running leaner…

I mean, both do that but yes, the plates would tip it in without adding track width like the LCA would, so technically I guess it would give you more fender clearance. That's only going to be a possible issue on very wide and tall tires like 295/40 and up.

I purchased my set of GTC02 from Aspec and got them in four days. They even reached out to make sure I wanted the size I ordered to make sure they would fit (18x10.5)

Yup, also if you want more negative camber than just one can give you. I have both on my car and run -3.7 in the front.

@Evolution I wonder if you could pound the rotor shields flat? The reason the rocks get stuck is because the shields are all wavy.

It's just like the Evos, you need an actual continental flex fuel sensor wired into the ECU and the ECU tuned/modded to have flex fuel tables properly setup. (see screenshot below) What is *not* like the Evos is that you have to also add port injection to run full E85. Things get complicated...

That's not correct. If you change camber from the top where the whole wheel/hub/strut assembly moves forward/aft, you do not gain/lose any clearance. Same thing with the lower LCA, the whole assembly moves forward/aft. If you have one of the older designs of MacPherson where the strut assembly...

Yup, there are tables in the ECU for specifically this reason.

I think @zrk is talking about straight line drag racing and most of us are talking about track use with corners and lateral forces that sweep the gas from saddle to saddle. It's 1000% a real thing on tracks with corners where you turn your steering wheels and with big right handed sweepers...
