The two main leaders are still the RT660 and A052. The Nankang CR1 isn't too far behind, nor the V730, but no one in our big region is running these. The Conti's are too new, but are an endurance tire. I'd go with an RT660 even if it meant a narrow "225". The Falken's run wide anyways. A 225 is virtually fits like a 235 despite the number. With that said, being your son is learning and doing daily driver duties, I don't think putting him on the fastest tire is the best way to learn. I tell everyone who's picking up the sport to run on something like a Conti ECS.... 300-400TW, not top tier tire for a year. Get the driving down a bit, a good line, all that... then increase mechanical grip. I see too many newbies run out and order the best tires and then rely on those for a decent time, but not improve their driving for a long while.

I ran the 224/45/17 A052's on the stock PP wheels. I did add the 3mm spacer and I had plenty of room left between the strut and sidewall. Much more than the RE-71R's in 225 on the +53 wheel. I got 149 runs out of them exactly. They have a few more in them, but that was my run count for the year. They're below the wear bars, but the outer edges held up with -1.3 degrees camber. On a good note, I moved up from 37th to 31st in a highly competitive region. Our 10 top were just about all winning at nationals this year.... so yeah. The A052's worked, but I don't know if they were the best for the car in DS. My main grip was they overheated quickly. My morning runs were good, but afternoon once it heated up, I rarely improved. Many times I was sitting in the top 15 (out of about 100) going into the afternoon, but ended up falling to around 25. I'll likely try to RT660's this year as most in my region have switched to these for prices and their ability to take more heat. Price-wise, the A052's in 225/45/17 were $800 last year and $1000 this year. RT660's are up, but now those are ~$650 ($550 last year). I'm up in the air again with wheel choice. The PP wheels worked last year with the A052's being 21lbs. The RT660's are 24lbs, so the1 15.7lb weight of the STI wheels would be ideal. The 660's run wide, probably wider than the Yoks, so we'll see which I decide to roll the dice on. The good news is once I fit the 660's on the PP wheels with the 3mm spacer and find I have more than 5mm of clearance, that confirms they're fit with the lighter STI wheels.... for the year after. I still think the 660's will work better for our climate and the BRZ in street class with limited camber. The Yoks worked ok, but didn't seem ideal - likely due to the lack of camber. But they made it and didn't disintegrate in <50 runs like many said they would. They would be AMAZING on an STX setup with -4 degrees of camber and 245's.

I've not had any issues with RT660 break-in but am running on concrete in Lincoln. I got about 90 runs out of the RT660s even with rotation and flipping on the wheels. But the GTI's brake vectoring heat-cycled them pretty hard. A seam was showing on one tire when i sold them, so though still safe, delamination was beginning.
