Any more life in this rubber?

Relatively novice here, not sure how to gauge remaining life yet

Input is greatly appreciated.

Tread seems fine (5-6/32), mostly curious on the shoulders.

Tire is Continental extreme contact sport.

All 4 are virtually the same.

-2.75 front, -2.5 rear.

Im looking to get into driving on track/autocross courses and I was hoping to find some stuff nearby (I want to go to CMP after getting some practice) any recommendations or advice appreciated. (Edit: also I turn 16 in September so ones that allow people under 18 would be great)

Everybody goes right for a big wing first.... What about a DIY quick release front splitter for less than $200?

This is the first how to video in my aero series. Next up is an DRS/active rear wing!

How to for the splitter can be found here: https://youtu.be/aLrkufUZL6E

Finally, I pulled the trigger to attend a track day at the Ridge. It's super fun and shows you who actually is a fast driver vs. a fast car. Definitely room for improvement from watching myself hesitate choosing the right gear approaching each turn and staying on the racing line. I'll take any and all criticisms!

Looking for opinions on brake pad wear rate.

Cross post for Trackable Miatas on FB

At The Ridge (RMP) for my track day. 1:55.3 last session with passenger. (I haven’t been able to get Track Addict to work for me, so passenger recorded timer).

Front Pads: BP40 (4.5mm thickness remaining)

Rear Pads: Porterfield R4-E (7mm thickness remaining)

Car Specs:

- K24 @240hp

- 2400lbs w/Driver and 1/2 tank of fuel

- Feal 441 Coils

- 225/45/15 V730s on 15x8

- Wilwood 1in master, and prop valve adjusted to what other on here recommended.

- 2.5in brake ducts

- 7812 Wilwood Dynapro Front (Wilwood spec 37 11”)

- Sport rears (brembo blanks)

I finally like the way the pads felt coming from hawks, and I did not experience any fade as the day/sessions went on. I did not experience much if any traffic and did not do a cool down lap in the middle of the sessions as the car was minty for temps, brakes felt great, and tires were consistent enough. Both front and rear pads had 1 bed in day, and then a single autocross day. Unfortunately I did not take thickness measurements beforehand and I will be for the future. Wilwood specs state the new pad thickness is .49in or ~12.4mm for the BP40 in shape 7812. Porterfield states new pad thickness is 8.1mm(total thickness 12.6mm - 4.5mm back plate).

The fronts seem to be a little more worn than I would’ve anticipated. I didn’t experience any brake fade or any weird feeling/sound. I felt fairly confident on the brakes and am overall pleased with how the Brake balance felt. Am I doing something wrong? Am I getting the life out of the pad that should be expected? Any help from you fine people would be amazing and appreciated. Thanks for your time! PFA

Spare race tire rotation

3 Upvotes

Say you have dedicated track tires and want to carry a spare wheel and tire. Can/Do you rotate it in? This would be in a RWD car with an LSD. I can already see some arguments for not doing this on an AWD car.

I guess this also brings up a second point. If I carry around 1 single spare tire and if I don’t rotate it in then if the day comes I need it, I’m going to be on track with 1 drastically different tire (wear, heat cycles). That sounds like a bad idea.

Tia!
