Has anyone ran these tires?

They're cheap, I was wondering if they'd be a good alternative to cheap trackday tires since the Federal RSR's are starting to get a bit more pricey.

 

For the same price (less actually) I'd just get RS3s.

 

Where?!?

$516 for a set of 4

These are $480 for a set... granted it's $9 per tire, but you can get some nice tire stems for that much. Plus the RS3's are on special, likely won't be by the time I need new tires.

 

I'm running them right now got them from tire rack so far my impression on this tire is really amazed. I had the z2's prior similar grip just a little more flex since the z2's are known to have very stiff sidewalls. I've run the RSR's and my friend drove my car and he runs rs3's and he loved the the way the car handled with these tires. Definately a tire to try out.

 

Nice, thanks. I still have half the life left on my R-S3's on my track wheels. But these will definitely be going on next.

 

I have a set on my AP1. I broke them in and took them to the Dragon. 741 miles of spirited driving through the mountains. So far, so good. More to come.

 

I tested them and they were very similar to the other Extreme Performance tires in the test. While they were not quite up to the RE71R they were in the same ball park. If I can help let me know.

Thought I'd drop a review in here. Got these on early spring and have run them for about 12k miles now. They're probably at around 25-30% left with 60 miles/day highway plus some spirited driving and a few autocross sessions. Overall pretty happy with them, grip has started to fall off pretty good at this point, however some of this may be attributed to me swapping them left to right due to some mild camberwear. I'm just a bit more careful now especially in the rain but still feel really good in the dry. Not sure if I'll get another set next year, probably not, I was on a decent budget this year and will probably spend the extra $100 or so for a set to get something better.

I will say they can be very loud, 80mph on the highway with the top up and I thought my diff was going to blow. I swapped a diff, CVs and even did a thorough wheel bearing check because I refused to believe that these tires were that loud. Once I swapped right to left the noise all but disappeared.

 

I put 3 trackdays and 6k miles on a set, replaced the rears with another set of SUR4. I think they are great tires for the price, but definitely loud.

 

Had my first track day at Heartland Park Topeka last week with these tires. They replaced RE71 that I had trashed in only 2 previous outings. I was able to drop 2 seconds of my lap, with no obvious excessive tire wear.... and at 75% of the RE price
