Let's Talk Track Tires - 2022 Edition

Has anyone compared lap times between CUP 2's and A052's? I need new tyres and am deciding between them. Cup 2's are $2000 per set and A052's are $2600 AUD. Keen to hear anyones experience with how their lap times and respective durability compare If I can get more than 6 track days out of a set that would be great but I doubt the A052's last longer than the Michelin's do.

If you happen to have a wet track at some point you can put 10 seconds between yourself and someone on Cup 2.

Yoko significantly faster, the exact difference depends on the individual track. They also wear significantly faster. Softer sidewall so more vague steering but I don't find that a huge issue in a Porsche sports car. Biggest gain is in traction limited zones and slow corners.

Wear rate is a big downside, but I don't find that they drop off as much as a cup 2 in terms of lap time over its life span. After 10-12 cycles you start to feel the edge of that massive traction being lost a little, but it's not terrible. Cup 2 hold thread for very long but the second half it's just hard rubber without much grip.
Cup 2 tend to do their fastest lap when they're brand new. 052 are very good brand new but they are at their absolute best after 2 or 3 cycles. It's important to cool them all the way down at that point though to get that crazy record lap grip on the first flier after that.

Love to turn: On the Goodyears, What wheel widths and offsets are you using? Any rubbing or other issues?

Any one tried them on GT4 yet? Was a lot of hype when they were announced. Looking at sizes, only option would be 265/35 and 295/30 which would mess with the rake a bit. Curious if anyone has given these tires or this size a go?

I am not competing for any prizes so I will stick with CUP 2's for now. If my mate in his Lotus ends up threatening my lap times I might splash for A052's but while I am just driving for fun and not competitively I am keen to avoid getting into arms races.

The rubbing appears to be caused by the larger tires especially the 265 front tires. So if your are still running 245s in the front then maybe it wouldn't an issue. A 255/295 combo could also work well. I definitely like the 40mm stagger from front to rear over the stock 50mm of OEM stagger. Better bite into the corners, less understeer, and just better overall balance in the car for me. The car also rides a little lower than stock due to the original factory setting and then adding so much shim to the front and rear LCAs of the car to get the desired negative camber. It will be raised about 2mm the next time I adjust the alignment. All these things will fine tune the set up and should get rid of the tiny rub that I had with the Trofeos. I have yet to get the tar remover out to clean the rubber off of the wheel wells to see if the GYSC3Rs are currently rubbing.

Wheels are 9x19 ET50 and 11x19 ET48 Forgelines. The tires are 265/305-19s which fit ok but with a bit of rub on the inside of the top of the fenders. Already been through one set of tires without any damage to the them. The Gooodyears are slightly smaller to my first set of the now discontinued Trofeo Rs so they appear to fit a little better...... snip ...I have yet to get the tar remover out to clean the rubber off of the wheel wells to see if the GYSC3Rs are currently rubbing.

I will be putting on motorsport camber plates since the front tires are pretty far out with the shim maxed out to get -3.02 and -3.05 of camber. Then I can remove a few mm of shim on the front LCAs to tuck the front wheels back in. A front offset of 55 could have solved this problem had I known better, but no one else had brought it up before. The rubbing appears to be caused by the larger tires especially the 265 front tires.

SPRING RATIOS (front/rear)
GT4 Springs: 45/80 = 56%
Swift Upgrade: 60/80 = 75%
4RS Spring: 100/140 = 71%
The stock fronts are overly soft for the track but nice on the road. An upgrade to 60Nm front springs will balance the ratio to be more like the RS, which will help the handling balance of the car. Less nose dive under braking, more level in cornering, still compliant for some forgiveness, and less expensive. An easy upgrade for those who would like to stay closer to OEM. Then there is the full spring upgrade with the tried and true 80/100 Nm Swift package that so many people have already put into service.

Camber plates are up next with probably some 60Nm Swift front springs at the same time. No real extra labor to install at the same time. It won't be RS stiff, but will certainly be an improvement over the current 45Nm ones. They will also blend in nicely with the standard rears, not over stress the shock tower mounts, and remain well inside the shock dampening characteristics of the standard PASM shocks. The caster pucks are great and further tighten up the steering response of the car.
