What did you do to your Supra today?

[Gabe]

Cut the break pad wear sensors, bypassed them and tucked them away.

I don’t need no stinking pad sensors telling me when I need to change the pads.

I haven’t driven the car, but seems that the car did not notice when I cut them

Tested my new QuickJacks

Next to the cooling/heating mini-split system, quickjacks has been the best garage purchase I have made.

I'd venture a guess that it only checks when the car is started, similar to when it looks for burnt out bulbs and such.

Replaced my Guibo. Rear end clunk/vibration is gone.

Also tried one of those $150 amazon lips...It broke before I even left my apt complex. Cheap brittle plastic + 30 degree weather.

When did this clunk happen for you?

Can't wait to see what mine looks like, I can't even see out the rear view mirror at WOT the whole car vibrates so much.

When did this clunk happen for you?

I was doing 2-3 track days a month for 10 months out of the year for ~3years with the car, plus being at Tennessee Intl Raceway every weekend when not at the track.

I'd say the increased stress from the driving did it in. It's not as bad as I've seen, but it is a wear item.

Did the audio “upgrade” still need to get zip ties so I can get the mesh on there but overall I am happy with my work.

How's the bass quality now? I'm going to work on mine this weekend.

I previously ran the Verus rear diffuser and while it did a decent job, the whole bottom-rear end of the Supra could really be improved in terms of drag and downforce. I recently posted the rear bumper cut and today I modified a new diffuser that has about 50% more surface area for air to attach to (vs the Verus). I've CAD designed a bracket that's still in queue to be CNC'd, but if things go as planned, this new setup will be lighter than the Verus diffuser by about a few lbs while reducing more drag providing additional downforce.

It definitely helps with the rattles and release of energy into the hatch area. It will never be anything like an after market setup but it does sound better.

Awesome. Pls share pics of it once installed. And opinions on how it works.

I'm a youtube certified aerodynamicist as of yesterday after watching this video. Something something tire squirt strake and mount it further forward. Regardless you might find something useful from this.

I got aero consultation from JFK Aero a little over a year ago before I ordered parts. Obviously regarding the A90, but specifically class limitations on aero, adding/removing what's allowed in said class and optimizing from there. There's so much nuance to what can make aero work properly, whether the weight added, drag is worth the downforce, and so on and so forth.

I had a pretty basic knowledge of how aero functioned like most of us, but I found tons of value from the consultation. Mostly from debunking repeated misinformation on the internet... like how people seem to repeat how diffusers are not useful and actually harmful without running a full floor. Untrue. The diffuser needs to be setup correctly for it's application. Most classes that are "street" do not allow a full floor, but allow front aero and rear aero typically within 3"-5" inches of OEM body line. Considering that, a rear diffuser is still very much useful without a full floor, but it needs to be positioned correctly.

Without a full floor however, you won't get max benefit, which is why I opted to get a larger rear diffuser last in my setup.
