updated. added my time from this morning as well:
hrd..... VE SS Commodore...... Nankang AR1...... BCs, exhaust..... 1:00.75 Natsoft

Lakeside I assume, good time, less than one sec to get to the Zed's best.

Not technically a PB but I finally cracked a 1:09 at Wakefield Park on Street Tyres yesterday. Been trying to do that for 5 years. I feel like that's more of an achievement than my time on A050's from back when I couldn't drive for shit.

Reedy - Wakefield Park - Mazda3 MPS - Michelin Cup 2 - 210kW - 1:09.9023

[trdee]

Now 1:08.65 (natsoft). Same specs except I've got 296mm brakes on the front now and BC coilovers

Now 1:07.7058. Same specs but with nankgang AR1 225/45/15s all round

[hrd]

biscan - added. Hopefully not much damage to man or machine
Neesan - yeah Lakeside mate. Went back yesterday with bigger Redline Brembo brakes, but no real improvement. 1:00.71, just 0.04 faster lol
Reedy - I updated your time/tyres. Pretty good getting 2 tenths away from A050s on street rubber!
Trdee - updated. Killing it on the Nankangs!

What lap timer do you use and are you using your phone to record out the front screen mate?

[Reedy]

Harry’s lap timer with external GPS and 3 gopros. Telemetry is done in post with racerender.

How much would you attribute the time (vs your AD08R time, 1:05.94) down to tyres?

How much would you attribute the time (vs your AD08R time, 1:05.94) down to tyres?

It's hard to tell as there were a couple of factors that contributed to the improvement.

More power (approximately 420whp vs 480whp), was up 7kmh on the back straight (223kmh vs 230kmh)
Better brakes (stock with PFC08s vs Alcon kit with FR6). Coming into turn 7 I was pulling -1.37g vs -1.05 with stock brakes.
I've done a bit of driver training since then so technique was better.

But I am very impressed with the tyres, definitely a big step up over AD08Rs, but definitely won't last as long.
Although AD08Rs run out of grip long before they run out of tread.
They don't need much warm up (my first lap was in the 64s) and they did 12 hot laps in a row with no real change in feel or performance.

On the road they feel a bit more compliant than AD08s and traction is much better, I can actually go full throttle in second gear without lighting up the tyres.
