@seamkv.supra / romanLegion9574's build log & history

[razorlab]

Most of its miles are on the street and it was horribly jumpy before -- can't have it go full racecar until I have a separate car as for regular usage. It does dial down the oversteer a bit. Honestly, with how bad WA roads are, I prefer the much more neutral alignment since there's a lot of unpredictability from the roads themselves with dips and bumps.

Also worth noting that it hooks up much better on a hard launch.

I do some occasional track days (less than before because of part time grad school commitments), so I'll see if this majorly compromises track performance when I'm out there next month.

The jumpiness was probably more to do with your front toe settings, just as an FYI.

I would monitor your tire wear with that front toe.

Yup, will do, thanks for the tip!

Took the car out for a proper brake pad break-in and to get a feel for it. The Endless RF 650 + Endless MX72 pads are killer at stopping the car. Excellent firm pedal feel (no sponginess) and it stops on a dime. The coilovers and sway bars also keep the car a lot more planted. I certainly have to relearn what the new limits are in corners.

Nice build, and great to hear about the performance of the pads. Leaning toward the Endless pads since I track, autocross, and street. Are they very loud on the street?

Not at all. No squealing like race brakes. They've been quiet so far, and they offer a bit more stopping power than OEM.

Dialed in the JB4 with a custom map 6 tune courtesy of @Jesse DaBears. The power delivery is so smooth now!

Checked in on this with a few miles down, and looks good so far. I'll keep an eye out for wear for a while more.

Installed these slip-on exhaust tips today, will take pics tomorrow.

They should hold me over till I finall decide on a valved dual exit titanium exhaust.

Exhaust tips -- not a perfect fit, but still pretty good IMO

RK Titanium charge pipe also installed. The engine cover doesn't clear the sensors, and will need to be cut.

Hit the Ridge today to get a feel for the car after all the track prep. It's hard to break old habits of where the edge of grip is; the new threshold is much higher.

After much experimenting, got down to a 2:01 on greasy PS4Ses during my last session of the day. I know for sure I can get into the high 1:50s in an earlier session and with more practice with the upgraded brakes (Endless MX72 + Endless brake fluid make it stop on a dime, I can brake much later or much less for the same effect).

Didn't time myself last time around, but I was keeping up with some 718 Cayman GTSes that were running 2:15s during my first time out there.

Added a Titan Motorsports exhaust from a local ex-Supra owner. Sounds killer, no rattle, a much deeper note, and awesome on the overrun!

What was the weight reduction with this setup?

Got a dyno run for the map6 today at Drift Office.

They told me their baselines were 350whp/350wtq for a stock '21. Good gains on the JB4, but looks like I'll need to go full FEMTO unlock for next steps.

So estimated gains of DP + map6 were 35whp & 95 wtq on 92 octane.

Track day photos in link. Down to a 1:56.7 at the Ridge, and the car and I still have more to offer.
